Summary

Adds ACP form elicitation support (clientCapabilities.elicitation.form and elicitation/create) to the CLI ACP runtime and routes requests through v0.3's canonical mcpElicitationForm + HostCurrentSessionInteractionsService.request pipeline. This enables interactive Plan Mode approval (exit_plan_mode), structured ask questions (including custom Other answers), and confirmation dialogs for ACP agents such as Oh-My-Pi (omp --acp).

Why

Closes #593

In @oh-my-pi/pi-coding-agent, post-prompt Plan Mode resolution (#resolvePostPromptPlanMode()) and interactive tools (ask, ctx.ui.select/confirm/input) check whether the ACP client advertises clientCapabilities.elicitation.form. Without it, Oh-My-Pi falls back to auto-approving plans immediately upon exit_plan_mode (exiting Plan Mode and executing the plan without user confirmation) and failing ask tool calls.

Routing ACP form elicitation through mcpElicitationForm and createPublicAcpPermissionHandler reuses the existing v0.3 InteractionTransientRequestV1 (questions and confirmation) and nativeAgentSessionInteractions pipeline while preserving active-turn custody (resolveRequestId, resolveTurnId, resolveCausalPermissionAuthority).

How to test

  1. Run the unit test suites covering mcpElicitationForm, createPublicAcpPermissionHandler, AcpBackend.fsEnabled, createAcpClientHandlers.permissionDecision, mcpDeclaredTransport, and nativeAgentSessionInteractions:
    ./apps/stack/bin/hstack-exec -- yarn --cwd apps/cli vitest run \
      src/plugins/runtime/invocation/services/mcpElicitationForm.test.ts \
      src/plugins/runtime/invocation/services/mcpDeclaredTransport.test.ts \
      src/agent/acp/runtime/publicSession/createPublicAcpPermissionHandler.test.ts \
      src/agent/acp/__tests__/AcpBackend.fsEnabled.test.ts \
      src/agent/acp/__tests__/createAcpClientHandlers.permissionDecision.test.ts \
      src/agent/runtime/registry/engineRegistry/nativeAgentSessionInteractions.test.ts
  2. Start an Oh-My-Pi (omp --acp) session in Plan mode and ask it to create a plan.
  3. Verify that when exit_plan_mode is called, Happier presents the interactive plan approval choices (Approve plan, Refine plan, Stay in plan mode) and waits for user confirmation instead of auto-executing.
  4. Verify that selecting Refine plan or Stay in plan mode returns the selection to the agent without cancelling the turn, and that ask tool questions (including Other (type your own) companion __other fields) map answers back to the ACP response content.

Notes (optional)

  • Preserves description on oneOf and items.anyOf choice entries in parseMcpElicitationFormSchema / mcpElicitationFormQuestions.
  • Collapses optional companion ${id}__other text properties into allowCustom: true when this preserves required fields; required companions remain separate questions. Custom answers retain an existing choice ID only when the companion title unambiguously identifies it.
  • ACP and both MCP consumers use one shared request builder. Presentation retains the actual question, respects the canonical 512-code-point title/label and 4,096-code-point prompt limits, and marks truncation.
  • Empty forms use the existing native single-choice question presenter for explicit confirmation, including in full-access modes. Request cancellation withdraws that interaction without cancelling its active turn.

Steward follow-up validation

Current-source focused checks cover the real native permission/interaction owners, ACP SDK cancellation, shared mapping, both MCP consumers, and the bound runtime registry. Canonical declaration preparation for Protocol and Session-core passes. Package semantic checks and the Oh-My-Pi/UI smoke recipe are tracked separately in the stewardship comment; focused test passes do not certify a live provider session.

Baseline declaration, schema-composition, and omitted observation-owner prerequisites are isolated in separate additive commits from the ACP refinement. The PR remains on v0.3; no 0.2 backport is included.

Summary by CodeRabbit

  • New Features
    • ACP sessions can display supported form-based prompts, including typed answers and confirmation requests.
    • Form support is advertised only when the host can handle these requests.
  • Bug Fixes
    • Cancelling an individual prompt no longer cancels the active session turn; later permission requests remain available.
    • Confirmations require an explicit confirm or cancel response, including in full-access modes.
    • Improved handling of optional form fields, custom “other” answers, and long prompts.

Walkthrough

The pull request adds ACP form elicitation through native session interactions and updates account-encryption currentness observations. It also changes schema construction and protocol types across the CLI and packages, with related tests and documentation.

Changes

Elicitation and native interactions

Layer / File(s) Summary
ACP elicitation contract and routing
apps/cli/src/agent/acp/*
The ACP client advertises form support when its permission handler provides elicitation, then routes elicitation/create requests and their abort signals to that handler.
Custody, permissions, and confirmation answers
apps/cli/src/agent/acp/runtime/publicSession/*, apps/cli/src/agent/runtime/registry/engineRegistry/*, apps/cli/src/agent/permissions/requestKind.ts
ACP elicitation resolves turn custody and uses native session interactions. Confirmation requests use question-shaped permissions and require an explicit confirm answer for approval.
Form conversion and MCP integration
apps/cli/src/plugins/runtime/invocation/services/mcpElicitationForm*, apps/cli/src/plugins/runtime/context/session/services/mcp.ts, apps/cli/src/plugins/runtime/invocation/services/mcpDeclaredTransport.ts, apps/cli/src/plugins/runtime/context/mcp.test.ts, apps/cli/src/plugins/runtime/.../*test.ts, apps/cli/src/agent/permissions/testkit/mcpToolPolicyFixture.ts, docs/agents-catalog.md
MCP and ACP form schemas produce bounded question or confirmation requests. Conversion handles defaults, choice descriptions, nullable ACP fields, and __other answers. Integration tests exercise session-backed permission flows and cancellation. The documentation describes the ACP form-elicitation contract.

Account encryption currentness

Layer / File(s) Summary
Shared observation and read lifecycle
apps/cli/src/api/client/accountEncryptionCurrentnessObservation.ts, apps/cli/src/api/client/connectedServiceCredentialApi.compatibility.test.ts
The shared observation tracks holders by token, supports reader-scoped cancellation, retains refresh errors, and invalidates matching malformed updates. Tests cover token-specific reads and shared observation lifetimes.
Requester admission and currentness tests
apps/cli/src/daemon/sessionEncryption/requesterAccountActionProjection.ts, apps/cli/src/daemon/sessionEncryption/requesterAccountCurrentness.socket.test.ts, docs/encryption.md
Requester admission checks the observed currentness witness and reads profile and currentness data separately. Tests cover HTTP fallback, credential attribution, and changed currentness facts. The documentation describes observation sharing and holder lifetimes.

Schema and protocol updates

Layer / File(s) Summary
Protocol schemas and exported types
packages/protocol/src/actions/*, packages/protocol/src/daemon/*, packages/protocol/src/plugins/*, packages/protocol/src/sessions/*, packages/protocol/src/updates/*, packages/protocol/src/usage/*, packages/protocol/package.json
Protocol schemas use updated Zod composition and explicit types. Terminal schemas are split into exported components, transcript metadata typing changes, and a protocol package export is added.
Agent and runtime schema updates
apps/cli/src/agent/executionRuns/*, apps/cli/src/agent/runtime/*, apps/cli/src/agent/sessionAttachPayload.ts, apps/cli/src/agent/tools/*
Agent, execution-run, and daemon protocol schemas adopt updated optional, nullable, and Zod Mini composition. Runtime identifier length checks and Voice declaration validation also change.
API, daemon, and plugin schema updates
apps/cli/src/api/*, apps/cli/src/daemon/*, apps/cli/src/plugins/daemon/*, apps/cli/src/plugins/projection/*, apps/cli/src/rpc/*
These schemas use Zod Mini helpers or top-level Zod wrappers. Direct-transfer and predecessor-compatibility request schemas no longer specify the prior explicit strictness.
Session, storage, and package schema updates
apps/cli/src/session/*, apps/cli/src/storage/*, apps/cli/src/workspaces/*, apps/ui/sources/sync/domains/messages/outgoingUserMessage.ts, packages/sdk/*, packages/session-core/src/raw/schemas.ts
Session and storage schemas adopt updated Zod APIs. The SDK adds Zod as a runtime dependency, and session-core switches to the full Zod import.

Explanation

The PR meets the coding requirements in [#593]. ACP initialization advertises clientCapabilities.elicitation.form when the handler is available, and elicitation/create is registered with abort-signal forwarding. The public ACP handler routes form, confirmation, accept, decline, and cancel outcomes through the native session interaction pipeline. The implementation preserves request custody, turnId, and causalPermissionAuthority, and it keeps request cancellation separate from active-turn cancellation. Shared form mapping covers multi-choice, single-choice, text, __other custom answers, nullable ACP fields, bounded prompts, and empty-form confirmation. Focused tests cover these paths, including refine, full-access confirmation, cancellation, and subsequent requests.

Full details: Out of Scope Changes check

Explanation

The PR includes changes with no demonstrated connection to [#593]. Examples include the new Account encryption currentness observation and related daemon tests, SCM result and request-kind changes, browser and SCM action typing changes, protocol export and schema migrations, SDK dependency changes, and unrelated session, storage, workspace, and documentation changes. These changes exceed ACP form elicitation support and its required tests and documentation.

Resolution

Remove the unrelated Account encryption, SCM, browser-action, protocol-export, SDK, and broad schema-migration changes from this PR. Submit prerequisite or maintenance work in separate pull requests, unless a concrete [#593] dependency is documented and limited to the ACP implementation.

Full details: Docstring Coverage

Explanation

Docstring coverage is 22.73% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 44 functions across 58 files. (1 skipped: 1 unsupported.)

Write docstrings for the functions missing them to satisfy the coverage threshold.

RetriggerView in GreptileConfidence Score: 5/5

[High impact] No unresolved code finding was established; merge still depends on the already-declared package and live OMP/UI checks.

Summary

Adds ACP form requests through the existing session interaction flow.

  • ACP agents can ask form questions and get answers through Happier.
  • ACP and MCP forms use the same question and answer mapping.
  • Account encryption observations now come from a shared API client owner.
  • Shared protocol declarations and runtime types keep their behavior while their schemas are updated.

No new actionable issue was established. The six supplied previous threads were rechecked; their original concerns are addressed. None has a supplied comment number, so previousFindings is empty. The first four threads were manually resolved without explanatory replies; the current code contains the corresponding fixes.

No tests, package checks, or live UI checks were run during this review. Full package validation and the current-source OMP/UI recipe remain blocked, as explicitly acknowledged by happier-bot in the reviewer context. Those gates have not been waived.

- Bound elicitation prompts, descriptions, and labels to protocol limits (clamping with indicator)
- Preserve plan summary in question prompt when message exceeds 512 code points
- Retain matching choice ID on single-choice custom input and guard required companion other fields
- Stop mocking domain services in confirmation test by routing through createNativeAgentCurrentSessionUiServices
Name the existing schema and action-spec types without changing their runtime definitions. Extract browser approval policies once and preserve their inferred literal contract.

Validation: selected Protocol declaration preparation passes. Native semantic comparison introduces no diagnostics against the exact v0.3 base; the remaining 527 errors also occur on that base.
Move the requester observer to the existing API reader choke point and share only Account/Home encryption facts. Authenticate the credential before registration, retain fresh exact-witness HTTP reads, fence withdrawn facts around Home decisions, and report transport fallback without secrets.

Validation: requester projection 22/22 and qualified API 11/11 pass. Real-socket checks pass all 15 observation/finite-custody cases; four older Session/mode-reader assertions still fail against unchanged owners and are recorded separately.
…ation

Reuse one form request builder across ACP and both MCP consumers, normalize ACP nullable schema fields at its boundary, preserve required companion answers, and keep actual questions within canonical presentation limits.

Route native confirmations through the existing question presenter and answer normalizer so full-access policy cannot accept them implicitly. Delegate request classification to Protocol and carry SDK request cancellation through active-turn custody without cancelling the turn.

Validation: 43 native/ACP/target-action checks pass; shared form and composed MCP checks pass through real internal permission owners. Higher source integration and package gates remain separate validation.

Co-authored-by: Janar K <r2bit@users.noreply.github.com>
Use one explicit lifetime signal for materialized MCP bindings and their host owner so the existing native presentation admission can accept the fixture. Preserve the full direct, hosted, rebound and retirement assertions.

Validation: the selected dynamic/discovered MCP source-integration test passes through the real runtime registry and native interaction owner.
Replace unsupported classic-method calls on existing Mini schemas with their native functional operations throughout the reached CLI composition. Preserve refinements and unknown-key policy, reuse terminal authoring leaves, and keep raw-record construction on its classic factory while accepting core schema metadata.

Use the existing metadata schema and source export, declare SDK Zod ownership, and keep schema definitions at their established owners rather than adding adapters or parallel validators.

Validation: Protocol 165 focused checks, Session-core 159 raw checks, UI 7 outgoing-message checks, and usage 9 checks pass. Workflow/MCP 9 composed checks pass after the corresponding baseline fixture correction. Selected Protocol/Session-core declarations pass; all 34 remaining Session-core semantic errors also occur on the exact base. Full application semantic lanes remain separately reported.

Follow-up fixes are pushed at 1ef0bad7a3, keeping this PR on v0.3. Thanks @r2bit for tracing the Oh-My-Pi capability fallback and contributing the native elicitation path.

The refinements use one form request builder for ACP and both MCP consumers, preserve required/custom answers, normalize ACP nullable fields at its boundary, and retain the actual question within canonical presentation limits. Native confirmations now use the existing question presenter and answer normalizer, requiring an explicit answer even in full-access modes. SDK request cancellation withdraws the prompt while preserving the active turn; CLI request classification delegates to Protocol.

Separate prerequisite commits repair declaration emission and unsupported Mini schema operations, reuse the raw-record factory/metadata owner, and consolidate the omitted API encryption observation with the existing requester observer. The old competing observer is removed; exact HTTP witnesses remain fresh reads. Account authentication precedes shared observation registration, and held decisions cannot refresh away withdrawn facts.

Validation on the current source: 43 native/ACP checks, 165 Protocol checks, 159 Session-core raw checks, 7 UI outgoing-message checks, and the selected bound-runtime MCP integration case pass. Both MCP adapters and the shared mapper also pass focused checks. Protocol/Session-core declaration preparation passes. Independent review found no additional ownership or semantic regression.

This is not yet a merge-ready verdict. The Protocol semantic lane reports 521 errors and Session-core reports 34; exact-base diagnostic comparisons show every one of those errors also occurs on the public base. SDK declaration preparation is blocked by generated Action source that is also stale on the exact public base; its source/test check also reports 1,510 diagnostics, which have not all been individually attributed. Four socket assertions expect Session observation sharing absent from unchanged owners. CLI/UI semantic validation is still being completed. The actual Oh-My-Pi Plan/refine/custom-answer/cancellation UI smoke recipe has not been rerun here because the provider executable and a loaded PR app environment are unavailable. The original author's manual verification remains identified separately in the PR description.

The four original Greptile findings were valid; the fixes also cover adjacent context truncation, required companion fields, ordinary Custom choices and real permission-owner testing. Please review the current head and its separate prerequisite commits.

Narrow request/session-scoped SDK properties before access, retain the native Mini filesystem schema contract, and name the existing MCP fixture return type without changing runtime behavior.

Validation: 36 real-owner ACP checks pass. The four canonical CLI production partitions report 451 diagnostics, all exact-base matches; all 11 previously introduced occurrences are removed. The full CLI/test gate remains blocked in its baseline UI producer.
Remove the redundant canned-decline creator test and internal permission/service/presentation mocks from the changed target-action and runtime-registry cases. Use the canonical mutable Session/RPC boundary with real policy and answer parsing. Strengthen the actual SDK regression to cover cancellation, explicit decline, and subsequent acceptance in one active turn.

Validation: the 36-test unit batch, final 12-test SDK file, selected target-action case, and selected bound-registry source integration pass. Assertions cover published and completed state, outputs, owner retirement and cleanup.
Refine the existing observation reference count by exact authenticated credential. A decoded subject only locates a candidate: borrowing requires a live admitted holder of that credential. Unregistered tokens use their own existing HTTP read, and disposal withdraws only that credential while retaining other holders of the same Account/Home fact.

Validation: both forged-subject and last-credential-holder regressions fail before the fix and pass after it. Independent security review and all 22 credential compatibility tests pass; requester projection 22/22 and the 15 relevant real-socket cases also pass. Four pre-existing Session/mode-reader assertions remain separately disclosed.

The final corrective batch is pushed at a511526; PR remains on v0.3. Both actionable findings from the previous head are fixed and answered in their threads: exact authenticated-credential borrowing and tests through real permission owners. The additional type-only commit corrects ACP request/session union narrowing and names the existing Mini/fixture contracts.

@coderabbitai review
@greptile review

Please review this current head and the finding delta. Package-wide semantic validation remains failing: Protocol and Session-core diagnostic deltas were compared against exact public base, while CLI full checking is blocked by its imported UI declaration producer; SDK generation also fails on the exact base. Focused behavior and real SDK/source integration checks are green as reported above. Live OMP/UI smoke is still unavailable. These limitations remain explicit; this request does not claim merge readiness.

Review rate limited.

Exercise shared mode reads through the real credential client while retaining fresh exact-witness checks. Session bootstrap tests now follow their own authenticated HTTP reads and reject changed facts without inventing a Session subscription or cleanup retirement contract.

Validation: all 63 tests pass across credential compatibility, requester projection, and installed socket wiring. No production behavior changes.

Final head: 254fc0e. The additional commit only corrects four pre-existing socket-test expectations against their unchanged owners: mode borrowing now goes through the real credential client; Session bootstrap keeps its existing own-credential HTTP validation; cleanup is not treated as an unimplemented retirement API. No Session subscription or production policy was added. The complete credential compatibility / requester projection / socket batch now passes 63/63.

For the scope warning: these prerequisites were reached through the actual native interaction test entry point, not added as a general cleanup campaign. Protocol declaration preparation initially failed with TS2883/TS7056 in the ACP catalog, SCM/browser action and contribution schema owners. Real CLI collection then exposed invalid fluent calls on canonical Mini schemas, the SDK's invalid fluent omit, and the missing API-side observation module. The corrections use the existing schemas/native operations and one shared observation owner; separate commits retain that distinction. Public schema equivalence was checked across nine boundaries, and bounded CLI production diagnostics introduce no delta against the recorded exact-base comparison. Removing these changes would restore demonstrated load/declaration failures. Package-wide UI/SDK failures that remain unproven or unrelated are still disclosed rather than repaired broadly. The docstring percentage is inconclusive and does not justify adding repetitive comments.

The earlier CodeRabbit request was rate-limited; its advertised reset has now elapsed. Please review the current head. Package-wide semantic and live OMP/UI validation limitations remain open; no merge is being performed.

Use the real provider-enforced owner and authenticated Session RPC for confirmation, question, approval, requester isolation, cancellation, and malformed-response coverage. Reuse one fixture per owning suite and replace synthetic owner failures with real Session boundary faults.

Validation: native and session-scoped MCP suites pass all 21 tests. Fabricated workflow capacity throwing was removed from the native adapter test; its actual durable publication owner retains coverage.
Reuse the canonical nonblank opaque identifier reader for elicitation custody and replay sidechain tool calls/results. Preserve surrounding whitespace and Unicode so distinct provider identities retain distinct custody and replay keys.

Validation: both live custody and replay identity regressions fail before the correction. All 26 public permission, replay, and durable-outbox tests pass afterward.
Reuse admitted credential references and the existing connection supervisor when the active credential loses its final holder. Invalidate pending facts, retire the old transport, and reconnect with a remaining credential. HTTP refresh and unsupported-transport reads use the same live credential; stale transport callbacks and HTTP responses cannot publish after handover.

Validation: retired-credential 401 and original-bearer fallback regressions fail before the correction. All 65 currentness tests pass; independent handover replay passes three cases. Final native CLI production diagnostics introduce no delta against the recorded exact-base comparison; full package gates remain blocked by existing prerequisites.

All accepted corrections are pushed at 0f67631 (12 additive commits; original author commits preserved). PR stays on v0.3. The latest three findings are fixed and answered: real native/MCP permission-owner tests, opaque ACP IDs across live/replay paths, and live-credential observation handover. All nine review threads are now resolved with their source/test dispositions.

Final deciding checks:

  • Native + session-scoped MCP: 21/21 passed through real permission/interaction owners.
  • Credential compatibility + requester projection + real socket wiring: 65/65 passed. Independent handover/fallback replay: 3/3 passed.
  • Public ACP permission + replay + durable outbox: 26/26 passed after two intended identity regressions failed before the fix.
  • Native CLI production check includes all 66 changed production roots. Its 451 diagnostics all match the recorded exact-base comparison; zero current-only diagnostics. This remains a failing package prerequisite, not a green typecheck.

@greptile review

CodeRabbit's last review reports zero included reviews remaining; its new findings have been corrected and independently verified locally. A further current-head CodeRabbit review awaits available allowance rather than repeated rate-limited requests.

Merge readiness remains blocked by full package validation and the current-source live OMP/UI recipe. Full CLI checking stops in its imported UI producer; Protocol/Session-core exact-base comparisons and SDK stale-generation reproduction are recorded above. Remaining UI/SDK diagnostics are not all attributed to the base. No identified loaded PR app/provider executable is available for the Plan/refine/custom-answer/confirmation/cancel smoke. These gates have not been waived, and no merge is being performed.

@coderabbitai review

Requesting one current-head pass on 0f67631 now that more than an hour has elapsed since the earlier included review. The two latest findings are fixed in 7ea57d7 and 0f67631, with RED/GREEN evidence and independent handover verification in their thread replies. If shared allowance is still unavailable, retain that limitation explicitly; no repeated requests are needed while it remains exhausted.

Current-head review is complete at 0f67631: CodeRabbit approved this exact commit; Greptile reports 5/5 and no actionable finding. All nine review threads are resolved, and no new code finding remains from those reviews.

The twelve additive correction commits are pushed, the original author commits are preserved, and the target remains v0.3. Deciding behavior checks pass: currentness 65/65, native/MCP 21/21, ACP/replay/outbox 26/26, plus the independent three-case handover replay. The final production type comparison covers all 66 changed production files and has zero current-only diagnostics against its recorded base comparison.

This is still not a merge-ready certification. Full package checks remain failing; some UI/SDK diagnostics are not fully attributed to the base, and the current-source live OMP/UI smoke could not run without an identified loaded PR app/provider. The next required work is to clear those package prerequisites and run the declared Plan/refine/custom-answer/confirmation/cancel recipe on this source. GitHub currently reports APPROVED with merge state UNSTABLE. No merge or release has been performed.

Merged into v0.3 in b2e78c7.

Thanks @r2bit for implementing ACP form elicitation and for testing the Oh-My-Pi flow. Your contribution gives ACP agents a way to ask structured questions through Happier's existing session interactions. The follow-up fixes are included, and your original commits are preserved.

CodeRabbit approved the final head and Greptile found no remaining actionable issue. The package-check and live-validation limitations documented above remain recorded; merging does not mean those checks passed or that this is released yet.

Brings in the ACP form elicitation (#594) and the remote CLI/protocol fixes.
Three conflicts were resolved from both sides' intent:

- accountEncryptionCurrentnessObservation.ts: both sides moved the requester
  observer here. Keep local's Account Settings subscription and signed-request
  read path, and adopt remote's per-credential references and live-credential
  handover; a handover also tells Settings holders the channel disconnected.
- requesterAccountActionProjection.ts: local already authenticates the profile
  before registering the observation and fences withdrawn witnesses; keep it.
- plugins/projection/registry/projection/v2.ts: local already composes this
  schema with zod/mini; keep it.
