What Changed

Adds Oh My Pi (omp) as a seventh built-in provider, driving its native stdio ACP server (omp acp) through the existing generic ACP client stack (packages/effect-acp + apps/server/src/provider/acp/). No new transport, no new infra: the layout mirrors the Grok/Cursor drivers exactly.

  • OmpDriver — provider bundle; manual-only maintenance (T3 never guesses an omp update command); model catalog sourced exclusively from the probe ACP session's configOptions during status checks (nothing hardcoded).
  • OmpAdapter — session lifecycle on the shared ACP runtime: permission bridging via session/request_permission echoing the advertised snake_case option ids (auto-approve in Full access), elicitation bridged for both the typed session/elicitation method and the official-SDK ext method elicitation/create (flat {action, content} response — see fix(effect-acp): elicitation method name and response shape drift from official ACP SDK #9048 for why both are needed), omp task-tool calls projected into the Agents panel, steering merge via in-flight prompt counting, pre-prompt cancel.
  • OmpProvideromp --version probe + ACP model discovery; thought_level/context_size/fast configOptions map to reasoning/contextWindow/fastMode descriptors.
  • OmpTextGeneration — unattended commit/PR/branch/title generation with --auto-approve and elicitation disabled.
  • Contracts — OmpSettings/OmpSettingsPatch, off by default like cursor/grok/opencode; display name "Oh My Pi".
  • Web/mobile — provider icon, settings metadata, add-provider entry; model rows render the provider and upstream label per model (existing ModelListRow behavior, now reachable for omp).

RuntimeMode → omp approval flags: Supervised --approval-mode=always-ask, Auto-accept edits --approval-mode=write, Auto --auto-approve, Full access --approval-mode=yolo. Auth reuses credentials already under ~/.omp (omp's single agent ACP auth method); T3 manages no keys.

This is a rebase of the driver work from #9038 onto current main, with the review findings from that PR resolved (auto reasoning normalization, task-tool key allowlist, theme-adaptive icon, text-gen auto-approve, semaphore release on stop/failure, failed-turn terminal event, pre-prompt cancel) and main-drift fixes (maintenance resolver API, removed PROVIDER_OPTIONS import).

Why

omp ships a maintained native ACP server, and T3 already ships a complete ACP client runtime — the driver is a thin shim on proven machinery. The alternative user path today (an OpenCode-driver instance pointed at the omp binary) cannot work: omp does not speak the @opencode-ai/sdk server protocol, so those instances fail with "Timed out waiting for OpenCode server start". Discussion: #10883.

UI Changes

Checklist

  • This PR is small and focused
  • I explained what changed and why
  • I included before/after screenshots for any UI changes
  • I included a video for animation/interaction changes (N/A — no motion changes)

Validation

  • pnpm tc clean; server/contracts/web suites green, including ~30 omp adapter tests covering streaming, approvals, elicitation (both wire shapes), model-switch-without-respawn, cancel, and subagent projection.
  • End-to-end against a real omp 18.1.15 install: 11.9k-model catalog discovered via ACP, streamed turn rendered in the built desktop UI.

Summary by CodeRabbit

  • New Features

    • Added Oh My Pi as an Early Access provider, disabled by default.
    • Supports dynamic model discovery, custom models, model and thinking options, session resume, approvals, user input, task tools, cancellation, and streamed responses.

🟠 High src/model.ts:224

When only omp is enabled, automatic text generation sends gpt-5.6-luna (DEFAULT_TEXT_GENERATION_MODEL) to session/set_config_option, overwriting or rejecting OMP's current configured model and preventing generation until the user selects one manually. Because OMP_DRIVER_KIND is registered here without entries in either default-model map, ModelSelection.model falls back to that unrelated default; add OMP-specific entries to both maps (or otherwise preserve its configured model).

Fixed in c2a565c: applyOmpAcpModelSelection now validates the requested slug against the advertised model configOption and skips writes for unadvertised slugs, so a cross-provider text-generation default (gpt-5.6-luna) can no longer overwrite or reject omp's configured model. Reasoning/context/fast selections still apply against the re-read options.

🟡 Medium Layers/OmpProvider.ts:379

Every discovered model receives the capabilities computed for the probe session’s currently selected model, so the picker advertises invalid reasoning choices or omits valid ones for other models. After a model switch, resolveOmpAcpConfigUpdates re-reads model-specific options and ignores those mismatched selections; capabilities must be derived per model (or refreshed when the model changes).

Fixed in c2a565c: capabilities are attached only to the catalog entry matching the probe session's current model (trimmed currentValue); every other entry reports null and the adapter re-reads per-model options at selection time, dropping mismatched selections. omp advertises a flat slug list (no per-model configOptions like Cursor), so per-model discovery is not available on this protocol.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🔵 Low · up to 75245

Oh My Pi generally works, but uncommon ACP option layouts or whitespace can select or report the wrong model, and two adapter tests can be flaky. These are bounded issues suitable for correction before or shortly after merge.

Store the effective model during session start.

applyRequestedSessionConfiguration now returns the model retained by ACP, but this call discards it. session.model then uses the requested value at Line 1043. If ACP does not advertise that value, ACP keeps its configured model while the new session reports the rejected model until a later turn completes.

Capture the result and initialize session.model from appliedConfiguration.model. Add a start-session test for an unadvertised requested model.

Review response (squashed into c2a565c, single commit on current main):

  • model.ts default-model maps (High): omp has no static default slug — its catalog is discovered dynamically from the ACP model configOption. applyOmpAcpModelSelection now validates the requested slug against the advertised options and skips unadvertised writes, so cross-provider defaults (e.g. text generation's gpt-5.6-luna when omp is the only enabled provider) preserve the CLI's configured model; reasoning/context/fast selections still apply against the re-read options.
  • rollback (Medium): supportsConversationRollback: false (Antigravity precedent); ProviderService gates on it.
  • per-model capabilities (Medium): omp advertises a flat slug list (no per-model configOptions like Cursor), so capabilities attach only to the probe session's current model (trimmed currentValue); other entries report null and the adapter re-reads options per model at selection time.
  • config/prompt atomicity (Medium): per-session dispatch Semaphore; permit spans configuration write → turn.started → dispatch registration, released on dispatched or prompt-fiber exit (raced), never across the prompt, so steers stay concurrent; join carries onInterrupt interruption.
  • !ctx.stopped success-settle guard (Major): added.
  • boolean model option / trim currentValue (Major/Minor quick wins): shared select-guarded findOmpModelConfigOption; trimmed comparison.
  • test runner rule: Effect.runPromise removed in favor of @effect/vitest; real-time polling suites use it.live (frozen TestClock would park them).

Gates on this commit: pnpm tc clean, vp check 0 errors, server 4317/4317, contracts 371/371, web 4453/4453 (ports-free runs; PortScanner's two curated-port cases are environmental when another listener holds 3000/3773). Also validated end to end against a real omp 18.1.15 install (11.9k-model catalog, streamed turn in the built desktop UI).

Use modelOption.id as the write target.

When a non-select model option appears before the select option, shouldWrite validates the select option but modelConfigId targets the non-select option. The code can then send a model slug to the wrong ACP option.

-      const modelConfigId = anyModelOption?.id ?? "model";
+      const modelConfigId = modelOption?.id ?? anyModelOption?.id ?? "model";

getOmpConfigOptionCategory and the local category probe apply the same normalization. No shared accessor change is needed.

Adds omp (https://github.com/can1357/oh-my-pi) as a seventh built-in
provider by driving its native stdio ACP server (`omp acp`) through the
existing generic ACP client stack (effect-acp), mirroring the
Cursor/Grok driver layout:

- OmpDriver: provider bundle; manual-only maintenance (T3 never guesses
  an omp update command); model catalog sourced exclusively from the
  probe ACP session's configOptions during status checks.
- OmpAdapter: session lifecycle on the shared ACP runtime: permission
  bridging via session/request_permission echoing advertised snake_case
  option ids, dual elicitation bridging (typed session/elicitation plus
  the official-SDK ext method elicitation/create with its flat
  response), task-tool subagent projection into the Agents panel,
  steering merge, pre-prompt and in-permit cancel checkpoints, and a
  per-session dispatch lock that serializes the configuration write,
  the turn.started stamp, and the session/prompt dispatch registration
  (omp applies model writes to the shared session). The permit is
  released on dispatch registration or prompt fiber exit (raced), never
  held across the prompt, so steers stay concurrent; the join carries
  onInterrupt interruption so post-dispatch cancels cannot orphan a
  prompt. Rollback is advertised unsupported: the ACP session cannot
  rewind its native conversation history.
- OmpProvider: `omp --version` probe plus ACP model discovery;
  capabilities attach only to the model the probe session currently
  runs (trimmed currentValue), other catalog entries report null. Owns
  both model-option selectors (select-guarded and unguarded existence
  probe) so their category/id normalization cannot drift.
- OmpAcpSupport: spawn args per RuntimeMode (Supervised
  --approval-mode=always-ask, Auto-accept edits --approval-mode=write,
  Auto --auto-approve, Full access --approval-mode=yolo); model writes
  only when the session advertises no model option at all (write
  through) or advertises the requested slug in its select model option;
  unadvertised slugs and non-select model options preserve the session's
  configured model, and the effective model is returned so callers stamp
  truthful turn/session state.
- OmpTextGeneration: unattended commit/PR/branch/title generation with
  --auto-approve and elicitation disabled.
- Contracts: OmpSettings/OmpSettingsPatch, off by default like
  cursor/grok/opencode; display name "Oh My Pi".
- Web/mobile: provider icon, settings metadata, add-provider entry;
  model rows render the provider and upstream label per model.

Tests: adapter/provider/support/text-generation suites on the shared
mock ACP agent covering the four model-write cases (no model option,
advertised slug, unadvertised slug, non-select model option), flat
elicitation responses, prepare-cancel permit release, dispatch
serialization order, thread-filtered event consumers, plus picker row
label coverage. Validated end to end against a real omp 18.1.15
install (11.9k-model catalog, streamed turn in the built desktop UI).
