Conversation checks and opt-in Claude replies for follow-ups (0.3.5) - #4
Merged
Merged
Conversation
….3.5) Follow-ups were judged by criteria that ask what the message itself says, so context moved probabilities without moving verdicts: in a probe on invented sessions, one displayed score in nine changed, and a follow-up failed "which file" even when the agent's reply had named it. Context alone cannot fix that; the criteria have to read the conversation. - Each check gains a conversation form in src/checks.ts: present if the follow-up supplies it, or the shown conversation settled it and the follow-up relies on it. Own threshold and inline eligibility; none is inline-eligible until the conversation eval measures it, so with replies on, always mode sends and records but shows nothing yet. - JEVPROMPTCOACH_SESSION_REPLIES=1 (off by default) sends the last two exchanges from Claude Code's transcript. src/conversation.ts keeps only the closing visible text of each turn: no tool calls, tool output, thinking or subagent records, and a *-bypassed exchange is dropped with its reply. Everything is redacted at the current level; metadata_only sends nothing. The transcript tail is read in about 4 ms. - fixtures-init --conversations builds unlabelled follow-up fixtures locally; eval --conversations measures and tunes against them and refuses unlabelled files. Both fixture sets and their raw eval output are gitignored and on the leak scan's forbidden list. - Wire tests cover each transcript filter, redaction of replies, the opt-in default and metadata_only; each fails with its guard removed. Thresholds for the conversation checks are placeholders until the fixture set has been labelled by hand and tuned.

Replies repeat .env lines, connection strings and command output, which prompts rarely carry. Probing the rules with invented values found ten shapes that went through untouched; each is now stripped at every privacy level, prompts included: - scheme://user:password@host (the password; user and host are kept). A Postgres URL in an env line was only caught before because the email rule happened to swallow "password@host". - Stripe sk_/rk_ live and test keys, npm_, github_pat_, SendGrid SG. - Slack and Discord webhook URLs, Azure SAS signatures. - Anything labelled password/passwd/pwd, JSON keys included, and names ending in _PASS, _PWD or _AUTH. The short suffixes need an underscore so bypass: or oauth: in code is not taken for a secret; false-positive cases are in the tests. Each new test entry leaks on main and is stripped here. The leak scanner learns the same key formats. Against local history: the prompt log holds nothing the new rules would change, and one of ~9,000 reply blocks had a URL credential (a placeholder on localhost), the shape this closes. A secret with no prefix and no label, like a bare hex token, still looks like a commit hash and is not removed. The README says so.
Redaction
- Hex runs of 16+ characters with a digit become [HEX] (0x prefix too).
Commit SHAs included: the marker still tells the scorer an identifier
was named, and UUIDs survive because their hex runs are shorter.
- A random-looking token of 20+ characters becomes [KEY]. Sized on real
history first: long mixed tokens there are mostly migration names,
slugs and constants, all with a 5+ lowercase run; keys switch classes
constantly. Across ~10,000 prompts and reply blocks it fired 7 times,
all on random shapes. Identifier false-positive cases are in the tests.
- Password and secret labels accept "is" as a separator ("the password
is x"), a shape found in real history that the rules missed.
Eval
- Both modes send what the plugin sends: every text through the
configured privacy level. The standalone set still clears 0.9 on every
measurable check; results re-baselined, movement within model drift.
- "never predicts fail" is no longer reported as "too few fail cases".
Conversation checks
- 40 follow-ups from local history labelled blind (before any Jev output)
by the agent, not a person; the fixture file stays gitignored.
- Against those labels, scoring with Claude's replies ranks
named_target at AUC 0.82 versus 0.63 alone; prompts-only context adds
nothing. success_condition's conversation wording credited every
follow-up (AUC 0.55); it was rewritten after that run to state the rule
the labels followed (a step like commit or deploy is not an end state),
which brought it to 0.78, level with standalone.
- Thresholds from --tune. Inline-eligible by the usual rule (CV
fail-precision >= 0.90 over >= 10 fails): constraints (0.97/34) and
verification (0.97/38), both flattered by base rate. named_target
(0.60/11) and success_condition (0.75/18) are recorded, not shown.

A follow-up now goes to Jev with up to the last two exchanges before it (the developer's prompts and the closing text of Claude's replies) unless JEVPROMPTCOACH_SESSION_REPLIES=0. Early in a session it sends whatever is there; the first prompt is still judged alone. Without a transcript, as on a Claude Code that does not pass one, it falls back to earlier prompts. Replies go through the same redaction as prompts, and a secret is as likely to be pasted into a prompt as quoted back in a reply, which is the case for the default. The filters in src/conversation.ts are unchanged. Tests: on by default, =0 falls back to prompts only, and the first prompt of a session with a transcript is still scored alone. Checked end to end against Jev with no settings: three prompts and two replies on the wire, 456 ms, and only the inline-eligible conversation checks on the notice.
- A queued prompt (typed while the agent works) is its own exchange, so the bypass rules apply to it and a *-prefixed one is dropped with the reply that answers it. Before, it was skipped and that reply was appended to the previous exchange and sent. - System and SDK messages close the current exchange and start an excluded one, so text answering them is never taken as a reply to the developer's prompt. Local transcripts carry about 400 such records. - Narration is dropped even when a record holds text and a tool call together; only blocks after the last tool_use count. No record does that today, so this is defensive. - The prompt being scored is recognised by promptMatchKey (preamble stripped, whitespace collapsed, hashed) rather than a hash of the raw text; about 4% of local prompts are split into several blocks in the transcript and missed the old match. Only an exchange with no reply is dropped, so an earlier identical prompt that was answered stays. The hook passes the key, never the text, and stripPreamble moves to src/hash.ts so the hook imports nothing new. - READMEs describe the [HEX] and [KEY] rules and narrow the stated limit to word-like secrets with no label. Each new test fails on the previous code.

…ency From an independent review of the branch; each item reproduced first. - A prompt queued while the agent works on a bypassed or otherwise excluded prompt inherits the exclusion. Before, the bypassed turn's closing text was filed under the queued exchange and sent. - Narration is dropped before any tool call type (server_tool_use for web search, mcp_tool_use), not only tool_use. - An unreadable transcript falls back to the earlier prompts in the log instead of scoring the follow-up alone. - Earlier prompts are clamped to the scorer's size before redaction. - url-credentials: empty user (redis://:pw@host), '@' or '/' inside the password; a port followed by a path is not taken for one. - random-token: the five-lowercase veto missed 20-37% of random tokens. Replaced by a digit requirement, a CamelCase veto (most capitals start a word) and a 0.40 class-switch ratio, judged per chunk and on the whole token, with '/' and '+' allowed so base64 secrets are caught. By simulation: 92% of random 20-char tokens, 97-99.9% from 32 chars, 99% of 40-char base64; no identifier false positives in the tests, and 5 hits across local history, all random shapes. - long-hex no longer skips hex after a hyphen. - Latency, including on main: a 50 KB run of dots, dashes or letters took 1.2-4.2 s in the email, azure-client-secret and hasFilePath regexes, on every prompt the hook sees. Bounded or anchored; now 20 ms or less. A test holds applyPrivacy under 250 ms on those runs. - test/fixtures/README.md: --count=60, which is what the CLI parses. Both evals re-run: standalone unchanged; conversation eligibility unchanged (constraints 0.97/34, verification 0.97/38).

From CodeRabbit's second pass; each reproduced by a test that fails on the previous code. - Context was clamped to the scorer's size before it was redacted, and replies were cut to their last 1,500 characters before redaction too. A credential across either cut became a fragment no rule recognises (redis://svc:<first half> with its @host cut off) and was sent. Now everything is redacted whole and clamped after, in the inline path and in fixtures-init. Redaction is linear since the last commit: a 1 MB reply takes 36 ms. - A meta record from the system or an SDK now closes the exchange before it, like a non-meta one. Local transcripts hold 11 such records. - Exclusions record why: a queued prompt inherits one only from a prompt that must not be shown, not from a system or SDK boundary, which hides nothing. A queued prompt after a system message is kept. - url-credentials takes the password to the last '@' a host follows, so one holding both '@' and '/' is masked whole. It can take a path with an '@' in it too; masking too much is the safe way round. No fixture text redacts differently, so the eval results stand.

fixtures-init --conversations kept earlier prompts, and the follow-up, at full length, while the scorer sends the first 3,000 and last 1,000 characters. A person labelling could then credit text Jev never sees. Every turn is now redacted and then clamped as the scorer clamps. Raised by CodeRabbit. The eval was unaffected, since it clamps before sending and clampPrompt is idempotent. In the local labelled set two context prompts exceeded the limit; both labels were re-checked against the clamped text and stand. A CLI test builds fixtures from an invented history and asserts the sizes and that no credential fragment survives; it fails on the previous code.

Summary
Follow-ups are now judged together with the conversation before them, Claude's replies included, on by default. Redaction also gets stronger for the kind of text those replies quote back, and the eval now redacts the way the plugin does. The conversation checks are tuned on 40 labelled follow-ups. Only the two that clear the usual bar show inline.
Changes
src/checks.ts, with its own threshold and inline eligibility, set by--tune.JEVPROMPTCOACH_SESSION_REPLIES=0falls back to earlier prompts only. Only the closing visible text of each turn is kept, and a*-bypassed exchange is dropped along with its reply. Everything is redacted, andmetadata_onlysends nothing. Reading the transcript tail takes about 4 ms, and the on-demand path is unchanged.github_pat_/SendGrid keys, Slack and Discord webhooks, Azure SAS signatures.passwordlabels (including JSON keys and "password is …") and_PASS/_PWD/_AUTHnames.[HEX], and random-looking tokens of 20+ characters become[KEY].fixtures-init --conversationsbuilds the set locally. The eval refuses unlabelled files.main. A 50 KB run of dots, dashes or letters took 1.2–4.2 s in three existing regexes (email, azure-client-secret, hasFilePath), on every prompt the hook sees. They're now bounded or anchored and take 20 ms or less, and a test holds this.@//in the password.Results (conversation set, 40 follow-ups)
Scoring with earlier prompts only (0.3.0) added nothing over scoring alone. The standalone set still clears 0.9 on every measurable check under redaction.
Notes
success_condition's conversation wording was rewritten after it credited every follow-up (AUC 0.55). The new wording states the rule the labels already followed.constraintsandverificationfail on most follow-ups, so their precision is flattered.
