feat(server): add Oh My Pi (omp) as an ACP provider - #10893
Conversation
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 with manual-only maintenance (T3 never guesses an omp update command) and a dynamic model catalog sourced exclusively from the probe ACP session's configOptions. - OmpAdapter: session lifecycle, permission bridging (session/request_permission with 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, and pre-prompt cancel. - OmpProvider: `omp --version` probe plus ACP model discovery; thought level/context/fast configOptions map to reasoning/context/fastMode. - OmpTextGeneration: unattended commit/PR/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, picker wiring; model rows show the provider and upstream label per model. RuntimeMode maps to omp approval flags: Supervised --approval-mode=always-ask, Auto-accept edits --approval-mode=write, Auto --auto-approve, Full access --approval-mode=yolo. Tests: adapter/provider/support/text-generation suites on the shared mock ACP agent (omp shapes incl. flat elicitation responses), plus picker row label coverage. Verified end to end against a real omp 18.1.15 install (11.9k-model catalog, streamed turn in the built UI).

🟠 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).

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).

Add the !ctx.stopped guard to the success settle path.
sendTurn is not protected by withThreadLock. If stopSession closes the session scope during ctx.acp.prompt, the prompt can resume with a cancelled success result. The success path can then emit turn.completed after session.exited. Match the existing error-path guard:

Does @effect/vitest it.effect provide TestClock instead of the live Clock?
💡 Result:
Yes, @effect/vitest's it.effect automatically provides a TestClock instead of the live Clock [1][2][3]. When you use it.effect, the test environment is automatically configured with a TestContext that includes the TestClock [1][2]. This allows you to simulate the passage of time deterministically without waiting for real-world time to pass, which is ideal for testing time-based effects like sleeps, timeouts, and schedules [4][5]. If you need to use the live system clock instead of the simulated TestClock, you should use it.live, which runs the test within the live Effect environment [1][2][3].

@effect/vitest it.effect TestClock it.live official README
💡 Result:
In @effect/vitest, the functions it.effect and it.live are primary test runners used to handle Effect-based tests with different environment requirements [1][2][3]. it.effect it.effect is the standard runner for Effect programs in tests [3]. It automatically provides a TestContext, which includes services like TestClock [1][2][3]. By default, this TestClock starts at 0, allowing you to perform deterministic, time-based testing without waiting for real time to pass [1][2][4]. When using it.effect, you can simulate time passage by using TestClock.adjust [1][2][3]. it.live it.live is used when you need to run tests in the live Effect environment rather than the simulated test environment [1][2][3]. This runner uses the actual system clock and is typically used for integration tests or when real-time behavior is required [1][2][3]. Key Differences Environment: it.effect provides TestClock and other test services for deterministic behavior [2][3], whereas it.live provides access to the real-world environment (real system clock) [1][2]. Usage: it.effect is recommended for most unit tests to keep them fast and deterministic [4][3]. it.live is specifically for scenarios where the test requires interaction with real-world time or other live services [1][2][3]. Cleanup: Both runners automatically provide and manage a Scope for every test, ensuring that resources are cleaned up once the test completes [2][3][5]. In summary, use it.effect when you want to control time deterministically via TestClock, and use it.live when your test must interact with the actual system clock or live environment [1][2][3].

"@effect/vitest" "4.0.0-rc.112" it.effect TestClock it.live
💡 Result:
In the context of Effect testing using @effect/vitest (specifically in version 4.0.0-rc.112), it.effect, TestClock, and it.live are utilities used to control how time and side effects are handled within your test suite [1][2]. it.effect This is a test runner helper provided by @effect/vitest that allows you to write tests as Effect programs [1]. When you use it.effect, the Effect runtime handles the execution, allowing for features like automatic dependency injection and structured concurrency management within your tests [3][4]. TestClock The TestClock is a specialized service used in testing to control the passage of time [5]. It allows you to simulate the passage of time deterministically without waiting for actual real-world time to elapse [3]. This is essential for testing time-sensitive logic, such as timeouts, debouncing, or delayed execution. When using the TestClock, you can use methods to manipulate time, such as adjusting the clock or waiting for specific durations, which then trigger the completion of suspended effects [5]. it.live While it.effect is used for standard, isolated tests (often using mocked services like the TestClock), it.live is typically used for integration tests where you need to perform "live" or real-world effects [2]. Using it.live tells the test runner to execute the Effect program with a live environment—meaning it will use real system time, actual network calls, or real filesystem access, rather than the mocked or virtualized services that might be injected during unit tests [2]. In summary: - Use it.effect for deterministic, isolated tests, often paired with TestClock to manipulate time safely [5][3]. - Use it.live when you need to execute code against real-world side effects, bypassing the default test mocks [2].

Run the file-polling test with the live clock.
The third it.effect test calls waitForFileContent after the child exits. it.effect provides TestClock, but the child writes exit.log on real time. If the first read fails, Effect.sleep(25) waits for a test-clock advance, so the loop can remain suspended until the Vitest timeout. Use it.live for this test or provide the live clock to waitForFileContent.

What Changed
Adds Oh My Pi (

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'sconfigOptionsduring status checks (nothing hardcoded).OmpAdapter— session lifecycle on the shared ACP runtime: permission bridging viasession/request_permissionechoing the advertised snake_case option ids (auto-approve in Full access), elicitation bridged for both the typedsession/elicitationmethod and the official-SDK ext methodelicitation/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), omptask-tool calls projected into the Agents panel, steering merge via in-flight prompt counting, pre-prompt cancel.OmpProvider—omp --versionprobe + ACP model discovery;thought_level/context_size/fastconfigOptions map to reasoning/contextWindow/fastMode descriptors.OmpTextGeneration— unattended commit/PR/branch/title generation with--auto-approveand elicitation disabled.OmpSettings/OmpSettingsPatch, off by default like cursor/grok/opencode; display name "Oh My Pi".ModelListRowbehavior, 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 singleagentACP 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_OPTIONSimport).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
ompbinary) cannot work: omp does not speak the@opencode-ai/sdkserver protocol, so those instances fail with "Timed out waiting for OpenCode server start". Discussion: #10883.UI Changes
