Measures how well an agent completes real Plane tasks through an MCP tool surface, so tool-surface decisions rest on measurements instead of estimates — the last consolidation proposal's cost claims were off by 3.4x when measured. 34 tasks run against a live Plane API with fixtures seeded and torn down per task, each graded by a verifier that reads state back through the API rather than reading the agent's prose. Per task it reports pass/fail, tool calls to done, which tools were picked and whether they were optimal, errors, and the final answer. The harness is agent- and surface-agnostic. Five drivers (Codex, Claude Code, Antigravity, opencode, and the Anthropic SDK tool runner) all record real JSON-RPC traffic through a recording proxy, so call counts come off the wire rather than from self-report. Any stdio MCP server can be measured with --server-cmd, which is how competing PR surfaces were compared head to head. evals/README.md is the runbook; evals/DESIGN.md is the rationale. The task catalog keeps per-surface overlays so a surface that genuinely cannot do something is reported as a capability gap rather than a failure.

drivers.py had grown to 1947 lines holding four unrelated jobs: recording-proxy plumbing, CLI subprocess lifecycle, four vendors' transcript parsers, and the four driver classes. Each vendor's config writer, launcher and output parser sat scattered across it, so adding a driver meant touching the same file in four places and reading past three other vendors' quirks to do it. Now base/process/sidecar hold the vendor-neutral machinery and each vendor owns one module. Public imports are unchanged: evals/drivers/__init__.py re-exports the same names, built from the actual call sites rather than guessed. The boundary immediately paid for itself. Generic row mapping was reaching into Claude's usage parser whenever a CLI driver left usage_total unset, which would apply one vendor's token accounting to another's usage dict and report the result as fact. Drivers now own their own normalization and a missing total stays None, which is honest; a test pins that. Names that cross a module boundary lost their underscore prefix, since an imported name is a public name. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The in-process "sdk" path was not a driver: it lived inline in run.py, and get_driver returned None for it, so run_live carried two parallel code paths that had to be kept in sync. It also delegated the entire agent loop to a beta API (client.beta.messages.tool_runner plus the SDK's MCP tool conversion), which made one vendor's message shapes structural to the harness. The loop is now ours and provider-neutral. A backend owns conversation state and wire format behind start/next_turn/add_tool_results, so the driver deals in ToolCall and ToolResult and never sees a provider's block types. Anthropic runs on the stable Messages API; an OpenAI backend ships alongside it, importing lazily and taking an injectable client so the package stays uninstalled and the tests stay offline. Adding a provider is now one module. Because the driver executes tools itself it holds every result in full, so response-token cost no longer needs a provider endpoint: a backend may supply a counter, otherwise the count is estimated from the text and the row says so rather than quietly reporting an estimate as measured. The behaviour that carries correctness is preserved and now tested directly: tools are never executed on a refusal-terminated turn, results pair to calls by id rather than ordinal with a mismatch flag when ids do not line up, and iteration exhaustion is only flagged mid-tool-loop. Every row field report.py and existing result files depend on is unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Only the in-process driver could report what a tool response costs in context, because it was the sole path holding the result text; CLI rows carried a "no API key" marker instead of a number. That silently limited the metric to one driver, and the metric is a large part of why the harness exists. Both paths now derive tokens from one shared estimator, so they cannot drift, and rows say when a count is estimated rather than measured — report.py labels a column estimated, measured, or mixed instead of presenting all three alike. Exact CLI-side counting is available but off by default: the proxy can retain serialized tool-result text for a real tokenizer to count, at the cost of writing live workspace data into the sidecar. For comparing surfaces the default estimate is monotonic in the quantity being compared, so the precision is rarely worth that trade; the README says so where the flag is documented. The proxy stays stdlib-only — it runs inside the server's process tree with a scrubbed PYTHONPATH, so tokenizing happens in analysis code, never there.

tasks.py was 2798 lines: the catalog, 34 verifiers, answer matchers, API lookup helpers and prompt binding. Adding a single task meant opening all of it. Tasks now live with their own verifiers, grouped by class — read, write, schema, cross, debias — because those are edited together, so splitting data from behaviour would only mean two files open for every change. Shared machinery moves to common.py, and the package takes over the evals.tasks module path so every existing import is untouched. Task order is load-bearing: battery_fingerprint hashes the catalog and every result file we have carries that hash, so a reordering would silently invalidate comparisons against past runs rather than fail. The fingerprint is unchanged (6425dcc64404, 34 tasks) and a test now pins the id order. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
run.py was argparse wiring, model-alias resolution, the live run loop and the canary in one 976-line module, so the entry point and the machinery it drives could not be read or tested apart. cli.py now owns argument parsing and dispatch, runner.py owns run_live, the canary and their row/resume/meta bookkeeping, and runner never imports argparse. run.py stays as a thin delegating shim because python -m evals.run appears in every script, runbook and doc we have; its CLI behaviour and --help are unchanged.

Four phases of refactor left DESIGN.md instructing readers to build the driver on the Anthropic beta tool_runner and "not improvise alternatives" — which is exactly what we did, and for reasons the document should now explain. It also still described the harness as a walking skeleton with a section on what was not built yet. It is now the rationale for what exists: what each metric buys, why verification reads the API back instead of grading prose, why call counts come off the wire, and where the driver/backend seam sits. Roadmap sections are deleted rather than updated; git history is the roadmap. The README's prerequisites claimed a Business/Enterprise licence was required. It is not: the mock flag server enables every flag regardless, and a workspace with no licence row seeds every fixture — checked by canary rather than argued. Restored with sharper wording: the feature-flag cache trap (a cached answer from the wrong flag server makes gated endpoints 402 and looks exactly like a plan problem, so it is worth checking first), and the fact that Codex rejects the short model aliases the harness forwards unchanged.

The driver called itself generic while being Anthropic-shaped: it imported both
concrete backends and picked between them with an if/else, and the loop branched
on Anthropic's own stop_reason strings ("refusal", "pause_turn"), so any other
provider had to impersonate Anthropic to work. Adding a third provider meant
editing the supposedly generic driver.
Stop reasons are now an enum we own, with each backend mapping its provider's
values in, and backends register themselves so the driver imports none of them —
a test registers a dummy backend and drives the whole loop through it to prove a
new provider needs no driver changes. The enum's serialized values match what
rows already carried, so old result files stay comparable, and each turn keeps
the provider's raw reason for debugging.
Model tiers were the same leak one level up: sonnet and haiku were the harness
vocabulary, so every non-Anthropic driver mapped from a vendor it has nothing to
do with, and codex-cli forwarded "sonnet" to a CLI that rejects it. The tiers are
now standard and fast, resolved per driver and per provider, with every mapping
verified against the provider rather than assumed. Anything that is not a tier
passes through untouched. OpenCode's tiers are deliberately unmapped because its
models are project-configured: it fails with instructions instead of guessing,
since a plausible wrong ID silently benchmarks a different model.

Every CLI driver repeated the same sequence: temp dir, write the vendor MCP config, wrap the server command in the recording proxy, run it, parse the vendor's output, harvest the proxy on timeout, reconcile, assemble an AgentRun. Four copies of one algorithm — and the duplication had already cost us, because the process-group kill, the timeout harvest and a wrong-server bug each had to be fixed in more than one copy, with no way to tell whether a copy was missed. CliDriver now owns that sequence once and the vendors express only what differs: write_mcp_config, build_command, invoke_cli, parse_output, plus validate_run and finalize_run for the two drivers that need them. Claude, Codex, Antigravity and OpenCode drop 250 lines between them. Free functions stayed free on purpose. strip_mcp_prefix, normalize_tool_call, normalize_claude_usage, the vendor parsers and the token estimator have no vendor polymorphism and no state; as methods they would need an object to test and would drift toward coupling to self. The line that matters is whether shared logic dispatches on it, not whether it happens to live near a class. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A result row was an untyped dict of ~32 keys, built in pieces across runner.py and the driver row mapper, and read in report.py through some thirty separate .get() calls. Nothing declared the shape, so a new field had to be threaded through every construction site by hand — which is how result_tokens_estimated was added — and a mistyped key read as None and reported as zero. CallRecord and TaskResult now own one to_row serializer and one from_row reader, with an explicit schema version. Usage's short on-disk keys survive as part of that declared schema rather than a hand-maintained "legacy" shim; a docstring records that nothing in-repo reads them and they exist for humans and ad-hoc analysis of stored runs. Reading old files is the point, not a nicety: past batteries are what the harness is for. from_row loads pre-change rows, proven against real rows lifted out of battery4 and battery5 files rather than synthesized ones, and report output on those files is byte-identical to before this change. wall_time_s now means the same thing everywhere. Codex measured the CLI invocation while the other three included our own config setup, and the field is compared across drivers. It excludes setup for all of them, mirroring how the API driver times the agent loop alone; rows written earlier include a few milliseconds of setup for three drivers. A test now pins the template contract itself: a minimal subclass inherits proxy-first call counting and timeout harvesting without reimplementing either, which is the guarantee the base class exists to provide.

Verifiers that scan free text measure how an agent writes, not what the tool surface can do. C2 had run 25 times and passed 6 — split by agent that is claude-cli 6 of 8 and codex-cli 0 of 17, because it hunted for changelog content in prose and a terse-but-correct answer never matched. Read at face value that says a surface is worse under GPT, which is false. R2 had the same shape: the prompt asked for "the integer count only" while the verifier matched the number anywhere in the text, so "There are four urgent open work items" failed. Ten tasks now state an explicit output contract in the prompt and match it exactly — the pattern the de-bias tasks already used. A correct answer in any style passes; an absent or wrong one still fails, which the canary proves by rejecting a do-nothing agent on every task. Prompts are part of the catalog, so the battery fingerprint moves from 6425dcc64404 to 182c4748ef14 and results for changed tasks are no longer comparable with battery3/4/5. That is the honest consequence of fixing the questions rather than the answers, so the README says it and report warns when a table spans fingerprints instead of silently comparing different questions. Five unrelated semantic gaps were found and deliberately left alone rather than tuned: R7 accepts any exact state without proving the transition is legal, W8 cannot verify "yesterday" because the worklog surface has no logged-date field, W10 checks a page's name but not its body, W3 checks one distinctive phrase of the requested comment, and L2 counts activities without checking the phrases.

Every battery so far has been n=1, and we have seen tasks flip between near-identical runs, so differences of one or two tasks are currently indistinguishable from variance. Measuring that noise floor needs the multi-rep path to be trustworthy, and an audit found it was not. Multi-file --table selected the last row per task and dropped earlier repetitions from cells and totals, so a five-rep battery would have rendered as one sample per task while looking like five. --reps 0 or negative ran nothing and exited successfully. A/B call-count comparison used the last successful repetition rather than a median, letting run order move the answer. Tables now aggregate every completed repetition, report per-task k/n with a Wilson interval, flag tasks that did not answer identically each time, and state the resulting minimum meaningful difference between surfaces. Single-rep files render exactly as before, which nearly all of our stored results are. Two caveats are documented rather than papered over: resume files do not record the intended rep count, so raising --reps works while lowering it leaves higher-numbered reps in place.

seed.py was 1152 lines: client construction, the dry-run plan text, plan-gate detection, project creation with identifier retry, workspace and project feature toggles, the workspace-artifact preclean, the dispatcher, ten fixture builders and teardown. It was the last file in the harness where unrelated work shared a module. Each Plane object now owns its own module — work items, labels, item types, cycles, modules, intake, customers, releases — with the dispatcher in build.py, teardown in remove.py, and project setup in projects.py. The package takes over the evals.seed path, so no import anywhere needed editing, and __init__ carries re-exports and no logic. Names follow simple-technical-English rules: plain words with one meaning, no abbreviations, and nothing named utils, helpers, misc, common, core or manager, since a module whose name has no membership rule collects whatever has no home. modules.py is named for Plane's Module object and says so. Verified by the live canary rather than unit tests alone: it seeds and tears down every fixture path against a real API, still rejects a do-nothing agent on all 33 live tasks, and leaves no projects behind.

report.py was 846 lines doing four unrelated jobs — statistics, row loading, summarising, and rendering — and it grew by 200 lines in a single session, which made it the fastest-degrading file in the harness. Each job now has a module: statistics, load, summary, table, compare, with the CLI in __main__ so `python -m evals.report` is unchanged. Statistics stays inside the package rather than moving to the root, because nothing else imports Wilson or the sign test; it graduates the day a second package does. The statistics themselves moved verbatim — a cleanup that quietly altered how an interval is computed would invalidate every past comparison while reading as cosmetic. Rows are now read only through TaskResult, so row-shape knowledge lives solely in results.py. What remains untyped is one level up: summarize() still returns a bare dict whose _meta keys the renderers reach into, which is the same problem worth fixing next. Verified by output equivalence rather than test count, on all three paths against the previous commit: single-rep tables, multi-rep aggregation on a file with deliberately unstable tasks, and the A/B comparison. All byte-identical. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Three changes that all reduce noise rather than move it around. runner.py was 753 lines with run_live about 300 of them: seeding, driving, verification, row assembly, teardown and resume bookkeeping interleaved in one function, which made it the hardest code here to follow. It is now a package — live, resume, meta, canary — and a single repetition runs through its own function with a thin loop around it. Splitting it into root modules would have traded one problem for another, so the package keeps evals/ root from growing and every existing import still resolves. token_counting moves into drivers, whose two modules are its only consumers. The rule we settled on is that a helper lives with its user and graduates to the root when a second package needs it; keeping it at the top level advertised a shared dependency that did not exist. The default output directory becomes evals/output, because evals/results.py and evals/results/ differed only in punctuation. An existing results directory is left on disk untouched — it may hold earlier runs — and stays ignored. Verified through the real loop, not fakes: the live canary still rejects a do-nothing agent on all 33 tasks, and a live two-task run passes with nothing left behind in the workspace. A decomposition that reordered teardown against verification would pass the offline suite and only fail on a battery. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The harness once measured three tool surfaces served by one server: full, v2, and v2-schema. The v2 work is set aside, and no server this tree can launch reads PLANE_MCP_SURFACE — so `--surface v2` ran the legacy server under a v2 label. Every real comparison used --server-cmd, where overlay-based tool-choice classification is disabled anyway, which left the whole overlay mechanism dead. A run now says what to call its column (--label, free-form) and what server to launch (--server-cmd / --server-env). Those were one flag before. - `--surface` becomes `--label`; rows carry `label`, and `classification` becomes `server`, which is `local` or `external` and says whether the mispick counters mean anything. - Task overlays, resolve_surface_tool_sets, and PLANE_MCP_SURFACE are gone. Tasks keep one optimal/alternate set each; no prompt, verifier, fixture, or tool set changed. - The `sdk` driver alias and its infra_sdk error class are gone: no result row on this machine ever used either. - evals/run.py was a facade holding a duplicate run_live that re-resolved the model. The command is now `python -m evals`. A skipped task keeps its own test now that overlays no longer supply one: a seed that raises TaskSkipped must record the skip, leave the success denominator empty, and still tear down. Verified live against a local Plane: the canary rejects a do-nothing agent on all 33 verifiers, and R1/W1 pass through the real driver with the workspace left empty.
evals/drivers held two kinds of driver in two different shapes: api/ was a package (one driver plus its per-provider backends) while the CLI side was eight loose files at the root, despite being the same shape — one template plus its per-vendor implementations plus shared subprocess and sidecar machinery. The CLI drivers now live in drivers/cli/, so each kind is a package holding its own machinery and the root keeps only what both kinds use: the driver protocol and the shared token estimate. base.py becomes protocol.py, which is what it holds and is a name we allow. Imports through `evals.drivers` are unchanged; only the modules behind that face moved.
The README opened by telling you to export PLANE_EE_API_DIR and PLANE_EE_VENV and run evals/env.sh, which made a plane-ee checkout and a second virtualenv look mandatory. They never were. The harness reaches its target through three EVAL_PLANE_* variables and knows nothing else about it, so a local plane-ee, a staging box, and a hosted workspace are the same thing to it. Those two variables were prerequisites of the bootstrap script alone. How a developer gets an instance to measure against is their own setup, so the script and the mock feature-flag server leave the repo; localdev/ is ignored. The prerequisites are now what they actually are: a reachable Plane with a key that can create and delete fixtures, and model access for the chosen driver. The local gotchas stay, including the feature-flag cache trap, which is the most expensive thing here to rediscover.
evals/drivers buried the two actual drivers a level down under filenames that described neither — api/driver.py held ApiDriver, cli/template.py held the CliDriver template — while the folders named after them held the per-vendor modules. Both drivers now live in drivers/driver.py, which leaves api/ and cli/ holding exactly what their names say. The two classes are concatenated, not refactored: they share nothing but the shape the runner calls. drivers/protocol.py is gone with them. It held an AgentDriver Protocol that nothing inherited, no type checker verified (there is none in this repo), and whose only consumer annotated its own parameter as Any — plus REPO_ROOT, which is not a protocol and was the third copy of that constant. get_driver now returns ApiDriver | CliDriver, which is both true and checkable, and REPO_ROOT is defined once in evals/__init__.py. evals/proxy.py keeps its own copy with a comment: it runs with the repo scrubbed off PYTHONPATH and cannot import its own package. Result types move to where results are defined. agent_run_to_task_result, agent_run_to_harness_dict, and AgentRun leave the driver package for evals/results.py — AgentRun has to move with them or results.py cannot import it without a cycle. token_counting.py and the MCP tool-name readers follow the same rule and graduate to evals/ now that two packages use them; the latter as tool_names.py, which is also what let results.py drop a deferred import that existed only to dodge that cycle. Restoring the two MCP translation helpers during the merge exposed that neither was tested, which is why a dropped `import json` broke no test while leaving any image-returning tool a NameError at run time. Both are covered now, and the mixed-content test was confirmed to fail without that import.
evals/tasks/common.py held three unrelated jobs under a name that described none of them and is on our banned list: binding a prompt to a seeded fixture, grading an agent's answer against a contract, and reading Plane to establish what is actually true. Those are now prompts.py, answers.py, and lookups.py, so a verifier author can see which of the three they need. TaskSkipped gets its own module rather than sitting beside PromptBindError. A skip is not a failure anywhere in this harness — the report keeps skips out of success denominators — and filing it under errors would blur the one distinction the reporting is careful about. tasks/__init__.py is now re-exports only; the catalog assembly, the pinned id order, and the fingerprint hash live in catalog.py. The package's public face is unchanged: `from evals.tasks import TASKS, get_tasks, TaskSkipped, ...` still works, and the task modules now import the specific module they need instead of a re-export. Placement only, proven by the fingerprint: it hashes every task's prompt and tool sets, and it is byte-identical at d546d3181bdb across 34 tasks in the same pinned order. All 22 definitions moved verbatim.
summarize() returned a dict of task id to dict, with the run-level totals smuggled in under the key "_meta". Seven places across table.py, command.py and compare.py had to remember that key existed, and forgetting one would either treat the totals as a task or drop them. Every field read was an untyped .get with a default, so a misspelled field name read as a missing value instead of failing. TaskSummary and Summary replace it. unstable, success, unstable_task_ids, and unstable_tasks are derived properties rather than stored fields, so the count of unstable tasks can no longer disagree with the list of them. No metric changed. Proven by byte-comparing all three report modes — single, table, and markdown table — over a real 34-task battery across three columns before and after: identical output.
_run_task_repetition was 183 lines nested six levels deep, and the error taxonomy ran through its else-chains. That taxonomy decides whether a failure is blamed on the agent or on the infrastructure, so it is the most consequential logic here and the least safe thing to restructure blind. So it was pinned first. Twelve characterization tests now drive run_live end to end and assert the recorded row for every branch: seed skip, seed failure, missing bug_type, prompt-bind failure, API-driver failure, CLI-driver failure, CLI timeout, error_max_turns staying a task failure, verifier skip, verifier error, external mispick nulling, and the success path's model identity. Five were new. infra_api had no test anywhere before this — the branch that decides whether a provider outage is recorded as a failed task. The function is now 73 lines of stage calls over seven helpers, each owning one stage and reporting whether to continue. Teardown still runs in a finally that covers every path, including skips and errors. Verified as behaviour-preserving three ways: the twelve tests pass unchanged against both the old and the new function; mutating three branches (api→cli, seed→task, max_turns→infra) each fails its own test, so they discriminate rather than merely pass; and a live run covering a success, a mutation, and a genuine env skip leaves the workspace empty.
The nine test_evals_*.py files were grouped by when they were written. Finding where something was tested meant guessing: test_evals_proxy.py was 2011 lines covering the recording proxy, the CLI driver template and model-tier resolution, and test_evals_hardening.py was 1423 lines importing from eight modules. tests/evals/ now mirrors the harness, so each source module has one obvious place. The autouse credential fixture and the row reader stop being duplicated per file and live in tests/evals/conftest.py. Placement only, proven two ways: pytest collects exactly the same 374 tests before and after, and all 300 test functions are byte-identical to their previous versions apart from one fixture path that had to change because its file moved two directories deeper. The five non-eval test files are untouched. They do carry three ruff findings that a wider lint scope now surfaces; all three already exist on origin/main and are left alone.
A full battery is tens of minutes long and printed nothing until each task had already finished — and stdout is block-buffered when redirected to a file, so a run in the background showed an empty log the whole way through. A stalled run and a working one looked identical, and the only way to tell was to parse the partial JSONL. Each repetition now announces itself before it starts, with its position in the run and elapsed time, and reports a running pass/fail/skip tally after. The run ends with one summary line. Every progress print flushes.

ensuring a failed cycles.list_work_items call cannot pass W6 based only on the
close signal.
In `@evals/token_counting.py`:
- Around line 29-49: Add tiktoken to the evals optional dependency extra so
count_result_text_tokens can use precise tokenization when the evals environment
is installed. Keep the existing fallback estimate behavior unchanged when
tiktoken is unavailable or fails.
In `@tests/evals/drivers/test_cli_driver.py`:
- Around line 331-334: Update the assertions in the test around
apply_proxy_sidecar to remove the redundant calls identity/equality checks and
assert the returned src value directly for the empty-sidecar fallback,
preserving the expected proxy or original-source behavior.
In `@tests/evals/drivers/test_vendors.py`:
- Around line 452-485: Update test_claude_driver_falls_back_to_transcript to
monkeypatch Path.home so find_claude_transcript resolves the planted transcript
under a temporary fake home rather than the real user home. Create the expected
.claude/projects directory beneath that fake home and remove the unnecessary
HOME environment mutation; retain the existing transcript assertions and
cleanup.
In `@tests/evals/runner/test_resume.py`:
- Around line 140-152: Rename the unused n_retry unpacked variable in
test_load_resume_skip_keys_truncated_json to _n_retry, leaving the tuple
unpacking and all assertions unchanged.
In `@tests/evals/seed/test_seed.py`:
- Around line 454-457: Update tests/evals/seed/test_seed.py lines 454-457,
478-481, and 500-503 to import and call remove_stale_workspace_artifacts instead
of _preclean_ws3_workspace_artifacts. In lines 510-536, import
CHECKOUT_TIMEOUT_TITLE and require_activities, then replace R5_TITLE and
_gate_activity_worker in both activity-gate tests with the new symbols.
In `@tests/evals/tasks/test_catalog.py`:
- Around line 157-161: Update test_tasks_module_has_no_hardcoded_uuids to
inspect the source of each task submodule, including read, write, and debias,
rather than only the evals.tasks facade; apply the existing UUID-shaped-literal
assertion across all collected module sources.
In `@tests/evals/test_cli.py`:
- Around line 14-45: Update test_cmd_list_prints_all_task_ids to derive expected
IDs from the TASKS definition rather than maintaining separate DESIGN_IDS and
EXTRA_IDS sets, and assert the parsed ID column exactly matches that expected
set. Avoid substring checks such as “tid in out” so IDs like W1 cannot match
W10; preserve the successful return-code assertion.
In `@tests/fixtures/evals_historical_rows.jsonl`:
- Around line 1-2: Sanitize the fixture’s machine-specific and personal
metadata: in the rows’ driver_notes, replace absolute temporary paths with the
neutral proxy-sidecar placeholder, and change the row 1 label from the personal
value to the generic historical-v2 value. Preserve all other fixture data
unchanged.

Nitpick comments:
In `@evals/drivers/driver.py`:
- Around line 245-291: Bound the API driver loop using the existing timeout
configuration: apply an async timeout to both backend.next_turn() and
mcp_client.call_tool() so stalled provider or MCP operations cannot block the
run indefinitely. Add a documented constructor-level tool-call timeout default
if needed, and record the timeout outcome with the established note or
stopped_reason="timeout" behavior so the run remains bounded and produces its
result.
In `@evals/listing.py`:
- Around line 176-196: Consolidate the duplicated setup in the server-command
branch around the command selection logic: keep only the differing command and
cmd_args assignments in each branch, then perform the shared label normalization
and _listing_stdio_env call with its existing RuntimeError handling once after
the branch.
In `@evals/report/command.py`:
- Around line 35-39: Update the argument validation in the command’s main flow
to reject --markdown unless --table is also specified, before dispatching
summary or A/B output paths; remove the unreachable len(paths) < 1 check while
preserving the existing empty-files handling.
In `@evals/report/table.py`:
- Around line 37-43: Rename the local token_mode variable in the report table
logic to a non-token name, and update all references in its mode checks plus the
later result_tokens_marker call to use the new name; do not add noqa
suppressions.
In `@evals/results.py`:
- Around line 555-560: Remove the no-op conditional checking run.usage and
run.usage_scope in the else branch, including its pass statement; leave the
existing cum_input, cum_reason, and usage_per_iteration initialization
unchanged.
In `@evals/seed/__init__.py`:
- Around line 103-171: Sort the entries in __all__ alphabetically to satisfy
RUF022, preserving every existing export and leaving the surrounding module
unchanged.
In `@evals/seed/cycles.py`:
- Around line 100-121: Export a shared constant for the “Session cookie not
rotated after login” fixture title from work_items.py, then import and use it in
the active-item lookup, overdue-item lookup, and overdue context assignment in
the cycle seeding flow, matching the existing PAYMENT_WEBHOOK_TITLE pattern.
In `@evals/seed/item_types.py`:
- Around line 42-46: Update the import flow containing
work_item_types.import_to_project to tolerate HttpError statuses 400 and 409
when the work item type is already imported, matching the handling in
seed_second_project; re-raise all other errors and import HttpError from
plane.errors.errors.
In `@evals/seed/releases.py`:
- Around line 23-34: Update the changelog seed flow around
plane.releases.changelog.update to catch only the SDK’s specific error type,
while preserving the non-fatal behavior. Record a boolean outcome in context
that is false on failure and true only after a successful update, alongside
release_changelog_text, so verifiers can distinguish seed failure from
verification failure.
In `@evals/seed/work_items.py`:
- Around line 129-131: Replace the assert checking urgent_count in the fixture
invariant with an unconditional RuntimeError when the count is not 4, preserving
the existing diagnostic message so validation occurs in all Python optimization
modes.
In `@evals/tasks/__init__.py`:
- Around line 71-141: Sort the __all__ entries in evals/tasks/__init__.py
according to Ruff RUF022’s isort-style ordering, preserving every exported
symbol and removing the lint violation.
In `@evals/tasks/catalog.py`:
- Around line 52-62: Update TASKS assembly to select the trailing read task by
its explicit task ID rather than READ_TASKS[6], while preserving the existing
catalog order and EXPECTED_TASK_IDS validation. Reuse the task’s established ID
value and ensure missing or duplicate matches are handled explicitly instead of
silently selecting the wrong task.
In `@evals/tasks/cross.py`:
- Around line 133-142: Update the changelog item normalization in the parsing
loop around markers and shipped to strip the full set of sentence-ending
punctuation characters, including periods, exclamation marks, and question
marks, while preserving the existing whitespace trimming and entry extraction
behavior.
In `@evals/tasks/debias.py`:
- Around line 159-178: Rename the local ids set in verify_i3 to a distinct name
such as cycle_item_ids, and update all additions, membership checks, and
diagnostic formatting in that function to use the new name while preserving
behavior.
In `@evals/tasks/write.py`:
- Around line 265-286: The archived-item lookup in the verification flow must
inspect all pages rather than only the first 100 results. Update the
list_archived logic around arch_ids to follow its pagination cursor until
exhausted, while preserving the existing exception handling and target-ID
membership checks.
In `@tests/evals/drivers/test_api_driver.py`:
- Around line 32-107: Move FakeBackend, FakeMcpSession, make_driver, and
run_driver from tests/evals/drivers/test_api_driver.py lines 32-107 into
tests/evals/conftest.py, then import the shared definitions in the original
module. Delete the duplicate definitions from tests/evals/test_results.py lines
28-103 and import the same shared versions there.
In `@tests/evals/report/test_table.py`:
- Around line 61-62: Tighten the assertions in the report table tests: make the
first assertion verify the value at the rendered i_err column position rather
than matching “2” anywhere in the output, adjusting column offsets to the actual
layout, and change the no-dedupe assertion to require the deterministic “1/2”
result instead of accepting either outcome.
In `@tests/evals/tasks/test_verifiers.py`:
- Around line 532-563: The tests currently duplicate the due-date arithmetic
instead of exercising the seed implementation. Extract the computation into a
named helper in the seed package, then update
test_f8_r3_due_date_clamped_to_iso_week and
test_f8_seed_r3_due_date_function_matches to call that helper while preserving
their existing weekday and weekend assertions.
- Around line 100-102: Move the section banner comments currently inside the
inner _go coroutine bodies to module level between the corresponding test
functions. Apply this consistently to the banners near the referenced sections,
keeping each banner immediately before the tests it describes and leaving
assertions and asyncio.run(_go()) behavior unchanged.
- Around line 40-41: Move the shared _item helper to tests/evals/conftest.py,
renaming its id parameter to item_id. In tests/evals/tasks/test_verifiers.py
lines 40-41, use the shared helper; in
tests/evals/tasks/test_debias_verifiers.py lines 44-45 and
tests/evals/tasks/test_output_contracts.py lines 26-27, import it and delete
each local duplicate.
In `@tests/evals/test_token_counting.py`:
- Around line 13-24: Add encode_ordinary to the FakeEncoding used by the test
for count_result_text_tokens, returning the expected token list and asserting
the serialized workspace result input; keep encode as the fallback
implementation so the test exercises the production-preferred branch.

Scope the TypeError fallback to the runner signature.
super().invoke_cli runs the CLI. The except TypeError block catches every TypeError raised anywhere inside that call, then invokes the CLI a second time. If a TypeError originates after the process starts, the agent runs twice. For write tasks this repeats Plane mutations and doubles quota use.
Detect the unsupported env= keyword before the retry.

Parse single-object JSON output, not only multi-line JSONL.
The aggregation branch requires a newline in stdout. opencode run --format json can emit one JSON object on one line. In that case final_text keeps the raw JSON string, and the output-contract grader receives serialized JSON instead of the answer text.
Add a single-object path.

Exclude unknown cum_input_tokens from the median.
TaskResult.cum_input_tokens is int | None, and from_row keeps None when the persisted field is null. Line 163 maps None to 0.0, so med_cum_input treats "not reported" as zero and understates the median. Line 160 already skips None for result_tokens; apply the same rule here.

The two sets contain 24 IDs. The PR objective specifies 34 seeded tasks. This test can miss omitted task IDs.

`enable_workspace_features(exclude={"customers"})` returned before calling the
API, so it only ever set True. That is sound for project features only because a
fresh project is created per task-rep; the workspace persists. S5 asks the agent
to enable cycles, worklogs and workspace customers, and its teardown then forced
customers back on — so from the second run onward one of its three clauses was
already satisfied before the agent acted. Both eval workspaces read
customers=True after full teardown.
Omission is not exclusion for project features either: page_view defaults to
True, so excluding pages by omission would have left the feature on. It worked
only because the two features S5 excludes happen to default false.
Excluded features are now written False. Teardown restores the value seeding
found instead of forcing True, since the harness runs against an instance it
does not own.
The fingerprint hashes prompts and tool sets, not fixtures, so this change would
otherwise redefine what S5 asks while still claiming comparability with earlier
results. CATALOG_REVISION makes that visible and is bumped here.

The evaluated agent holds Plane credentials and shell access, so it could answer a task without going through the surface being measured. Three reviewers named that the largest gap. The architectural fix - a separate server behind a harness-owned proxy, with the agent holding no credential - is designed but is multi-day work, and until it lands the property is an assurance argument rather than a measurement. Every run now reports four named indicators: a success with no Plane call at all, a mutating task that passed without any call that plausibly writes, a correct answer with no target-bound evidence where evidence was configured, and a call count far below the task's own observed distribution. They are named separately because they are different diagnoses, and each names the rows it flagged so a number can be investigated. Mutation intent comes from the catalog's own tags rather than a second list that would drift from the first, and the call-count rule compares against the observed distribution rather than a declared floor - this harness removed author-declared call floors precisely because hand-declared numbers became fiction. A plain outlier fence flagged ordinary one-call variation where the interquartile range is zero, so the rule also requires the count to be at most half the task median. Zero prints explicitly, because a silent absence reads the same as never having checked. The reported limitation is part of the output: this sees off-surface work only when it leaves a trace signature, and cannot see an agent that also makes convincing surface calls. Across 154 recorded live rows it flags nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Every report path now prints the off-surface indicators, including --table, which built its footer without them. Zero prints explicitly, because a silent absence is indistinguishable from "not checked". A comparison refuses any surface that lacks a tool_manifest_fingerprint. Missing is a value, not a wildcard — the rule already held within one file and now holds across A/B inputs, so the reporter can no longer print a comparison in which one surface is unidentified. Claude runs under isolated HOME, CLAUDE_CONFIG_DIR and XDG roots rather than inheriting ambient user state, and its transcript is copied to a durable artifact directory before the task directory is destroyed, so the reference a row persists still resolves when someone comes to read it. A failed credentials copy aborts instead of running the battery unauthenticated. The transcript location travels with the launch rather than living on the driver, so a concurrent runner cannot make one task read another's directory. The claims match the evidence. Claude's effective-config exclusivity rests on management readback plus the vendor's documented --strict-mcp-config contract, not on observing the evaluated invocation, and says so. Antigravity 1.1.13 has no introspection command at all, so its exclusivity is labelled unverifiable in the driver and in DESIGN.md rather than implied.

Comparing two tool surfaces is mostly a question about friction, and the comparison could not see it. Call deltas were medians of raw call counts over successful rows, so a surface on which the agent fails schema validation three times and succeeds on the fourth scored identically to one where it succeeded on the first — same pass rate, and the wasted calls read as "more calls" with nothing to say they were rejections. The proxy already recorded is_error per call and the row already persisted errored_calls. Nothing new is measured; what changed is that the comparison reads them. Both the absolute count and the rate are reported, because either alone misleads: a rate improves when extra successful calls dilute a fixed number of failures, and a count carries no sense of how much was attempted. Both are paired by task and bootstrapped over task pairs, matching how the call delta already treats tasks as the sampling unit. Every path that prints the call delta prints these too, zero included, since a silent absence reads as clean when it means unmeasured. is_error is the MCP-level failure flag, so this counts tool-reported failures rather than schema rejections specifically, and the reports say so.

The design claimed a repetition's fixture truth is reproducible from its persisted seed. It is not: seeding reads the current date for cycle and work-item dates, and an identifier collision retries with fresh randomness drawn outside the seeded namespace, so the same seed on another day builds a different fixture. What the seed does guarantee is the property it was built for and the one the harness depends on — each repetition's sentinels are independent, so no repetition can leak another's answer. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`codex exec` is non-interactive, so an MCP call that raises an approval request has nobody to answer it and Codex cancels its own call with "user cancelled MCP tool call". The agent then answers from nothing. That is not hypothetical: a live run recorded zero Plane calls on every task across three drivers while still emitting confident answers — one row reported "count: 3" for an urgent-work-item count it never queried. Verifiers caught it through missing target-bound provenance, so nothing scored as a false pass, but the battery was measuring the model's imagination rather than the tool surface. Config isolation is what severed it. The developer config routes approvals through automatic review; an isolated home inherits nothing, which is the point of isolation, so it has to say so itself. The test asserts the setting is present, because 562 passing tests said nothing about a run that made no calls at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A repetition that fails during seeding never launches an agent, so no tools/list is ever observed and there is no manifest to record. Requiring one anyway made mixed present/missing look like a mismatch and refused the comparison outright. That is not theoretical: the first live A/B was refused because six rows — L2 and L5, identical on both surfaces, failing in seeding — carried no fingerprint. Every statistic in the report already excludes those rows, so the refusal blocked a comparison that was sound in every respect it was meant to protect. Identity is now read from the rows that actually reached the surface. The rule the refusal exists for is unchanged: among rows that ran, a missing manifest is still a value rather than a wildcard, and a surface without one still cannot be compared.

# Conflicts: # uv.lock
`work_items.attachments.list` returns a bare `list[WorkItemAttachment]`, not the paged envelope every other list endpoint returns, so reading `.results` raised AttributeError. L5 died in seeding on every repetition of every run — six rows lost across the two A/B batteries — and it read as an environment problem rather than a one-line type mistake. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
L2's seeder required its randomized comment phrase to appear in the work item's activity readback. Plane's activity API never returns comment text — it returns the creation row and nothing else — so the requirement could not be satisfied by any agent, any worker, or any amount of waiting. L2 failed in seeding on every repetition and was absent from every result this harness has produced. Evidence is now the activity count bound to the seeded work item, which is what L2 asks for in its prompt and what its verifier already checks. The count comes from the same paginated envelope the agent reads, so provenance still requires a request that named the target and a response that carried the answer. CATALOG_REVISION 8: this changes what L2 measures. Nothing is lost across the transition, because before it L2 produced no rows at all. The pinned fingerprint and revision tests are updated rather than removed, and the gate test now encodes the new contract instead of the impossible one. Canary: 35/35 verified, 0 skipped, 0 errored — the whole catalog for the first time. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The live runner refuses to start a read task whose seed registered no target-bound evidence. It asked `configured_evidence_labels` for sentinels and targets and left out aggregates, so the gate was stricter than the matcher it guards: the proxy matches an exact total_count for a targeted request exactly as it matches a sentinel value. A read task whose answer *is* a count could therefore register its evidence and still be rejected as having registered none. L2 failed that way on all three repetitions of the first battery to reach it — the seeding bug that had hidden the gate was fixed one commit earlier, so this only became reachable now. The canary never saw it: it does not run the live seed gate. The test covers the predicate directly, including that targets alone and an unbound aggregate still do not count. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A work item's `state` is an id, so reading its name takes a second call: one names the work item and returns no name, the next returns the name and names only the state. Evidence bound to the work item alone demanded both halves in a single response, which no surface that returns state as an id can produce. R1 and I2 failed every repetition of the first full-catalog battery while answering correctly — the note read `answer_correct=true ... provenance=missing (0 evidence-bearing of 7 successful Plane calls)`. The consolidated surface returns `state` as a bare UUID, confirmed directly against v0.3.0, so the second call is the only way to the name. The seeded state is a target too. Both ids are seeded, so the agent must still name the thing it was asked about; it may now do so across the two calls the surface actually requires. Verified live: R1 and I2 both 0/3 -> 3/3. CATALOG_REVISION 9. Pinned fingerprint, revision and synthetic-battery values updated rather than removed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
R6 registered only one provable shape: a single count grouped by project_id. Counting each project separately reaches the same answer and is what every agent actually did, so a correct winner scored as unproven on all three repetitions. Both aggregate setters replaced the label's registered specs instead of appending, so a task could only ever have one acceptable shape — which is why the two could not simply be called together. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01J5kpUxiB9fd9apXJP6MA7K
A sentinel is a per-run random string that exists only inside Plane, and the agent's only route to Plane is the surface being measured. Its presence in a response the agent received is therefore proof on its own, so the request no longer has to name a particular entity. That target binding was an enumeration of approved routes through 183 actions, and it could never be complete. It rejected reading a state by listing a project's states, finding the active cycle by listing a project's cycles, and counting two projects separately — six defects in one week, every one a correct answer scored as unproven. Counts keep the binding, because a small integer is guessable where a random string is not. DESIGN.md now states both rules, and states that the harness measures a cooperative agent rather than an adversarial one.

A nonzero codex exit was scored as a finished attempt: the default stop reason was end_turn whatever the process did, so an authentication or network failure that still emitted a partial message got verified and counted in the success rate. opencode and antigravity already map a nonzero exit to error, so this skewed driver comparisons against them too. A plan-gated skip ends before the agent starts and so carries no tool manifest, exactly like a seed failure. Identity validation excluded only the latter, so one gated task made every offline report command exit 2 on a file the live summary called complete. Also: --dry-run described a project W11 does not build, the CLI listing test covered 24 of 35 tasks, and one usage branch did nothing.

Give L1 a worklog the agent did not create. Its answer was the id of the item it had just logged time on, and the write echoes that id, so both the answer and its provenance were satisfied without ever reading the project worklog summary the task exists to exercise. The seeded row is on an item the prompt never names. Count an undelivered line. Recording happens before forwarding so a fast child cannot race an unregistered pending id; the cost was that a broken pipe left a match in a sidecar still marked complete, proving surface use the agent never had. It now makes the sidecar non-authoritative. Restore the negative cases both transport tests lost: each had only responses that carry the sentinel, so a bug labelling every checked response would have passed, and the proxy had no wrong-target aggregate case at all. The retention claim was also wrong. A correct answer to R1 *is* the seeded state name, so sentinels do reach a row through final_text and verifier notes; only the response body and the evidence machinery are covered.

The test launches the real CLI in the scrubbed environment it is testing, and opencode can block on setup it cannot complete there.

work_logs.create takes a plain mapping where its sibling resources take request models, so L1 seeded nothing and failed as infra on every repetition. The offline fake now asserts the argument is a mapping, so passing a model fails a test rather than a battery. R6's second project had no Bug type of its own. Work item types are project-owned unless the workspace owns them, and its bugs were created carrying the main project's type id, so an agent resolving 'Bug' inside that project counted zero and named the main one — always in that direction, which is what gave it away. The oracle read those ids back directly and disagreed, so a correct agent was scored wrong roughly half the time. L1's contract was ambiguous once its summary held more than one row: "exactly one 'logged-minutes: 90' line and one 'summary-work-item-id' line for every row" was read by every repetition as one logged-minutes line per row. The clauses are now separate. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01J5kpUxiB9fd9apXJP6MA7K
One L1 repetition skipped as plan-gated on worklogs while the next two seeded and passed in the same workspace, and the reason string was all that survived — so whether it was a plan limit, a feature toggle, or a transient failure is now unknowable. The status code and message travel beside the reason, which stays byte-stable because the skip taxonomy matches it exactly.

is_plan_gate lived in seed/projects, so every seeder that could meet a paid feature imported the project resource module to reach it. That made projects a policy hub and produced the package's only import cycle, since item_types needs the classifier while projects needs the item-type seeder. Both now import seed/gates. stdio_server_env lived in runner/live, the live-run composition root, so importing a pure token-counting helper loaded 71 evals modules. It is now a leaf: that import loads 3. Source no longer routes TaskSkipped through evals/tasks/skip.py. That path shipped and a compat test pins it, but everything imported it while the canonical evals/errors was imported by almost nothing, which made the shim look like the real module. The layering itself was already sound in every direction that matters, so the new boundary tests pin it rather than change it: offline reporting must not drag in live-run code, fixtures must not drag in agent backends, and the proxy must not drag in either. One test proves the probe can observe a violation, so a boundary test that cannot fail does not pass silently.

Reports read three task facts from the live catalog: whether a task mutates Plane, its prompt text, and the fixtures it needs, which decides whether a plan-gated skip was expected. All three are properties of the run, so reading them from the working tree meant an old result file could be reinterpreted after the catalog changed — the exact drift the battery fingerprint and identity validation exist to prevent. The meta header now carries them, and report/ no longer imports evals.tasks at all. skip_taxonomy keeps a fallback for files written before the header existed, which is the only remaining path to the catalog and is now reached only by them. A file with no metadata cannot support the write-without-write-call indicator, so that indicator says "not evaluated" instead of printing a zero. A silent zero reads as checked-and-clean, which is the opposite of unknown.

drivers/driver.py held both the owned API loop and the CLI subprocess template. Nothing crossed between them — measured, zero shared names of its own, only stdlib and the two leaf modules evidence.py and results.py — so the two halves were sharing a file and nothing else. Each surface now names its shared abstraction the same way: base.py holds what the sibling vendor files implement. In api/ that is the renamed backend.py, the protocol anthropic.py and openai.py satisfy; in cli/ it is the CliDriver template the four agent CLIs fill in. ApiDriver keeps its own module because it is the single concrete loop, not a base. The api-local BackendFactory alias is gone. It named a different shape than the registry's BackendFactory in the same package, and the move put the two side by side; it had one use, now inlined. process.py, sidecar.py and base.py stay asymmetric between the two directories on purpose. A CLI driver never speaks to a model, so it needs no backend; the API driver owns its loop and sees every call directly, so it needs neither a recording proxy nor a process group.
evals/drivers/__init__.py re-exported forty names. Two of them, KNOWN_DRIVERS and get_driver, are what production uses; the rest were vendor internals — find_codex_rollout, parse_claude_transcript_calls, proxy_pid_path — re-exported only so tests could reach them through the package. Because Python runs a package's __init__ before any submodule, that wall made every consumer load all five agent CLIs. Importing evals.drivers.api.base, which shares nothing with them, pulled in the whole CLI tree: 108 modules became 699. Splitting driver.py did not fix this on its own, and could not have. Each vendor is now imported inside the get_driver branch that returns it, and tests import each name from the module that defines it. Reading the registry loads neither surface; asking for codex-cli loads the CLI side and not the API one, nor the other three vendors. Five boundary cases pin that, in fresh interpreters. They need a second probe: the existing one reduces a module to its depth-1 package name, so both surfaces read as "drivers" and the edge is inexpressible. The new probe matches full module prefixes, and has its own positive control.
evals/ had eighteen top-level modules, and a flat listing said nothing about what they were. Ten of them import nothing else inside evals: they are the vocabulary every other layer sits on, and errors.py at 21 lines looked like a peer of proxy.py at 860. Those ten plus results.py now live in evals/core/. The set is not a judgement call — it is exactly the modules that already satisfied "imports only each other", verified before the move. What makes this a boundary rather than a label is that membership is checked. A package named after its position in the dependency graph becomes a dumping ground unless the position is testable; here it is, so a boundary case asserts that importing any core module loads no evals module outside core. Membership is discovered from the directory rather than listed, because a hand-kept list makes the check opt-in — a module dropped into core/ and omitted from the list could import whatever it liked. Verified by planting a violating module and watching the case name it without any test edit. core/__init__.py deliberately re-exports nothing. A re-export wall there would make importing one core module load all eleven, which is the coupling just removed from drivers/__init__.py. Six modules stay at the top level. cli, cleanup and listing are entry points at the top of the graph, not vocabulary. proxy is a separate program spawned as `python -m evals.proxy`, so that path is public. skip_taxonomy imports the task catalog and result_lifecycle imports skip_taxonomy, so neither is floor — splitting result_lifecycle from results reads oddly but is honest. One assertion had to move rather than survive: BOUNDARIES pinned errors.py as depending on nothing of ours, but it matches depth-1 package names, and once results moved under core its depth-1 name became core, so the entry forbidding results could no longer match. Re-asserted at the granularity that survives the move: errors may load nothing beyond evals and evals.core themselves.
W1, W9, S1, S2 and S4 had no behavioural test. Every other part of the harness now has an instrument pointed at it, so these five were the last path from an agent mistake to an inflated headline. The cases ask what a loosened verifier would accept, rather than covering the happy path. W1 matches the auth label by seeded id, so a decoy renamed label fails, and it fails closed when the seed has no label id rather than letting the requirement vanish. W9 needs all three titles at high, not two of three. S1 only accepts a Severity reachable by type-scoped listing and distinguishes three outcomes that must stay distinct: authoritative 404 is a clean failure, a 500 is a VerifierReadError outside the denominator, and an unseeded bug type is a skip. S2 needs both the Fibonacci subset and the item estimate, via either the expanded or the UUID shape. S4 turns on the sign, so swapping accept and decline fails. Ten loosenings were applied to the verifier modules one at a time and all ten were caught, each by the case written for it.
Every claude-cli row was charged to infrastructure. The cause was one opaque boolean: the proxy reported pumps_alive if any of its three pump threads was still running at finalization, and one session with a live pump vetoed the merged trace. Claude Code opens two MCP sessions per task and signals them on exit, so the session that did the work finalizes with its stdin read parked on a client that will never write again. Measured on a live run: the only live stream was stdin, the call was recorded before the signal, and the trace was discarded anyway. A live stdin pump after a signal or child exit cannot have lost anything — no further request can arrive, and an in-flight request that never got its answer is already counted as an unmatched response. A live output pump is different: the server may have been mid-reply when the deadline expired. The proxy now records which streams were pumping rather than a bare boolean, which is what made this diagnosable at all. The raw fact stays in the sidecar; the consumer decides what it means, and sidecars written before the per-stream detail keep the old stricter reading instead of being reinterpreted after the fact. Verified end to end: the R6 smoke that failed as infra_trace now evaluates, with trace_integrity true, and scores as a genuine model failure naming zero Plane calls as the reason.
An eval of a tool surface gave the agent Claude Code's full built-in set alongside the 28 Plane tools. permission_mode is bypassPermissions, so the --allowedTools=mcp__plane__* argument granted auto-approval without restricting anything, and Bash ran unchallenged. Measured on a haiku subset: 11 of 24 repetitions made zero MCP calls. Each searched for a tool, did not call it, then spent its remaining turns in the shell. Ten exhausted the 15-turn budget with an empty answer. The eleventh succeeded — it added sys.path to the repo it was standing in, imported plane_mcp, ran `env | grep -i plane`, found the API key and called Plane's REST API directly. The work item really was added to the cycle, so the task verified as passed with no MCP call recorded at all. The driver now passes --tools= so the agent keeps none of Claude Code's own tools. That removes the bypass rather than merely detecting it after the fact, and it has a second effect: with the built-ins gone the total tool count falls under the threshold that defers MCP tools behind ToolSearch, so the surface arrives directly, the way every other driver already sees it. builtin_tools=None restores Claude Code's defaults for anyone who wants to measure the agent product rather than the surface.
Two fixes that both let a claude-cli run be read honestly. A session that never called tools/list was counted as disagreeing about the manifest. Claude Code lists tools in one session and makes its calls in a second, so the quiet one discarded the fingerprint on nearly every row and the reporter refused the file: its rows could not be shown to have hit the same surface. Silence is not contradiction, and two sessions naming different fingerprints is already caught by len(unique) > 1. Write verifiers read Plane back, which answers "did the state change", not "did the agent change it through the surface under test". Measured: an agent that could not work the tools out added the repo it was standing in to sys.path, took the API key from its own environment and mutated Plane over REST. The work item really was added to the cycle, so the task scored a pass with no tool call recorded at all. A write task that changed Plane with no successful tool call now fails and says so. Only when the trace is trustworthy — where integrity is false the row is already an infrastructure error and zero calls means the recording failed rather than the agent skipping the surface.
The project name is everything an agent gets: it is told the name and must resolve it to a UUID, because project_id is required by 121 of the 183 actions. A weaker model skipped that step and submitted a substring of the name as the id instead. "EVAL 3c128f21" got sent verbatim as project_id. An earlier attempt at this moved the hex into parentheses — "EVAL Delivery Planning (3c128f21)" — and made it worse rather than better: the parentheses turned the hex into a cleaner token to extract, and non-UUID project_id attempts went from 4 to 17 across six repetitions. That commit was reverted. The hex was the bait in both shapes, so the name no longer carries any. A word drawn deterministically from the run prefix keeps names distinct enough that a leftover project from a crashed run cannot make a name lookup ambiguous, and keeps R6's two projects apart — its expected answer is a project name. Teardown deletes by recorded project_id, so uniqueness in the name was never needed for correctness, and `evals.cleanup --prefix "EVAL "` still matches. Real projects are not named after UUID fragments. A fixture that invites a confusion the surface would never meet in production charges the model for the harness's own choice.
Two independent defects meant no agy row ever produced a measurement.
The driver ran agy under an isolated HOME. agy keeps its OAuth token in the
macOS login keychain, which Security resolves through $HOME/Library/Keychains,
so the override made the keychain unfindable ("A keychain cannot be found to
store \"antigravity\"") and every run failed unauthenticated. Isolate with the
undocumented --gemini_dir instead: it relocates agy's whole state tree, which
is all the isolation was ever for, and leaves the credential reachable. agy
ignores a relative value and silently falls back to the real tree, so the path
is resolved before use.
The prompt was passed as a trailing positional after a bare -p. agy parses with
Go's flag package, where --print (documented alias: --prompt) is a string flag
that consumes the next argv entry -- so -p took "--output-format" as the prompt,
the real prompt became a stray positional that ended flag parsing, and
--dangerously-skip-permissions never took effect. agy answered a question about
its own CLI and then denied its own tool calls. Every string flag now uses the
--flag=value form, with --print last, so argument order cannot matter.
Also drops the invoke_cli override: it existed to retry without env= for
injected test runners, and nothing reaches it now.
Verified live against eval-surface-a: C1 alone, then C1,S1,S2,S5,W5,W6,I3,R6 on
gemini-3.6-flash-low -- 8/8 rows evaluated, 7 pass, and the one failure is a
wrong answer rather than an infra error.

What this is
An eval harness for the Plane MCP tool surface, under
evals/. It runs a fixed battery oftasks against a real Plane instance through a real agent, records what the agent actually did,
and produces a report that either supports a comparison between two tool surfaces or refuses
to make one.
The refusals are the point. Most of this branch is not new capability — it is the harness
learning to decline to answer when the data cannot support the answer.
How it works
Tasks and fixtures. A battery is a catalog of tasks (
evals/tasks/), each declaring what itneeds. The harness seeds its own fixtures, runs each task N times, verifies the outcome against
Plane, and tears the fixtures down. A capability the workspace's plan excludes is skipped with a
reason rather than failing, so a battery adapts to the plan it meets instead of requiring every
feature flag forced on.
Drivers.
apiowns its own model and tool loop;codex-cli,claude-cli,opencode-cliand
antigravity-clidrive real vendor CLIs. Each CLI runs against an isolated configurationhome so the harness measures the surface it configured and not the developer's own MCP servers.
Recording. A proxy sits in front of the MCP server and records the JSON-RPC traffic, so the
trace is what crossed the wire rather than what the agent reported. Every recorded session must
finalize; a session that ends without its metadata is trace loss, and trace loss is typed as
infrastructure error and excluded from the success denominator rather than counted as failure.
Verification. A read task passes only if the answer is right and the recorded calls show
the agent got it from the surface. That second question is one property, not a per-task list of
approved call shapes: a seeder writes a per-run random value into Plane, and since the agent's
only route to Plane is the surface under measurement, that value appearing in a response it
received is the proof. Counts are the exception — a small integer is guessable, so an exact
total_countcounts only from a request naming a seeded entity. Expected values never reach theagent's side of the boundary: the config carries
(length, sha256)fingerprints and aggregateshapes, never the answers.
What it refuses to do
provider, driver and server are checked on raw rows before deduplication. A battery mismatch
is unconditional; other dimensions may be declared varied with
--vary. A comparison in whichany surface lacks a tool-manifest fingerprint is refused — missing is a value, not a wildcard.
its metadata, and a sequence gap are all loss.
rather than pass quietly.
What it measures beyond pass rate
provenance, implausibly few calls. Zero prints explicitly, because a silent absence is
indistinguishable from "not checked".
surface where the agent fails validation three times before succeeding scores identically to
one where it succeeds immediately.
not five independent trials. The pooled rate stays visible and is labelled pooled.
What it reports on the shipped surface
A full battery against v0.3.0 — 35 tasks × 3 reps,
codex-cliongpt-5.6-luna, 1h52m:[0.97, 1.00][0.95, 1.00]The single failure is a genuine agent lapse: it created a blocking dependency and never attached
the reference link. The offline reporter reproduces the live summary exactly, which exercises the
identity and report path on a real file rather than a fixture.
Read the success rate as a statement about this battery as much as the surface: one model, and 35
tasks that were iterated against while the harness was being built. It is strong evidence that the
instrument no longer manufactures failures, and weak evidence about tasks nobody tuned against.
The friction column is the more informative output — one task errors 26.7% of its calls while
still completing, which a pass rate alone cannot show.
Known limits, stated in the reports themselves
defeat the measurement. The evaluated agent runs as the same OS user, in the same filesystem,
holding the same Plane credentials, so it could edit its own result row, forge a proxy
sidecar, or skip MCP entirely. The indicators above catch traces of that; no verifier rule
closes it.
evals/DESIGN.mdstates this as a scope decision rather than leaving it to berediscovered. Closing it means running the agent in a separate trust domain — designed
separately, not in this PR.
is_errorcounts all MCP-level tool failures, not schema rejections specifically.not a full replay recipe — seeding also depends on the date and on collision retries.
