Metadata

  • Commit Message: fix(a2a): implement stub handlers and complete missing operations in A2aLocalFacade
  • Branch: bugfix/m8-a2a-facade-incomplete-operations

Background and Context

The A2aLocalFacade in src/cleveragents/a2a/facade.py is not production-ready as required by the specification to complete milestones v3.0.0 through v3.7.0. Many A2A operations are implemented as stubs or are explicitly marked as not yet implemented, meaning large portions of the A2A extension method surface are non-functional.

Code Evidence

  • Stub Handlers: _handle_registry_list_stub, _handle_context_stub, _handle_sync_stub, _handle_namespace_stub — these are placeholder implementations that do not perform real work.
  • Not Implemented: _handle_plan_explain returns a hardcoded 'Not yet implemented' message.
  • TODO comment: _handle_context_get has a TODO comment indicating it is not fully wired.

Affected Operations

The following _cleveragents/ extension method handlers are affected:

  • _cleveragents/registry/actor/list
  • _cleveragents/registry/skill/list
  • _cleveragents/registry/action/list
  • _cleveragents/registry/project/list
  • _cleveragents/context/inspect
  • _cleveragents/context/simulate
  • _cleveragents/context/set
  • _cleveragents/sync/pull
  • _cleveragents/sync/push
  • _cleveragents/sync/status
  • _cleveragents/namespace/list
  • _cleveragents/namespace/show
  • _cleveragents/namespace/members
  • _cleveragents/plan/explain
  • _cleveragents/plan/correct
  • _cleveragents/plan/rollback
  • _cleveragents/diagnostics/run

Expected Behavior

All A2A extension method handlers in A2aLocalFacade are fully implemented with correct business logic, delegating to the appropriate application-layer services. No handler returns a hardcoded 'Not yet implemented' message, no stub handler exists in production code, and no TODO comments remain indicating incomplete wiring.

Acceptance Criteria

  • _handle_registry_list_stub is replaced with real implementations for all four registry list operations (actor/list, skill/list, action/list, project/list), each delegating to the correct service.
  • _handle_context_stub is replaced with real implementations for context/inspect, context/simulate, and context/set, each delegating to the correct service.
  • _handle_sync_stub is replaced with real implementations for sync/pull, sync/push, and sync/status, each delegating to the correct service.
  • _handle_namespace_stub is replaced with real implementations for namespace/list, namespace/show, and namespace/members, each delegating to the correct service.
  • _handle_plan_explain no longer returns a hardcoded 'Not yet implemented' message and is fully implemented.
  • _handle_plan_correct and _handle_plan_rollback are fully implemented (not stubs).
  • _handle_diagnostics_run is fully implemented (not a stub).
  • The TODO comment in _handle_context_get is resolved and the handler is fully wired.
  • All stub handler methods are removed from production code.
  • BDD scenarios cover each newly implemented operation (happy path and error cases).
  • Integration tests exercise each operation end-to-end against real services (no mocks in integration tests).
  • Test coverage remains ≥ 97%.
  • nox (all default sessions) passes with no errors.

Subtasks

  • Audit src/cleveragents/a2a/facade.py and document the exact stub/TODO locations and the expected service delegation for each.
  • Implement _cleveragents/registry/actor/list — delegate to the appropriate registry service.
  • Implement _cleveragents/registry/skill/list — delegate to the appropriate registry service.
  • Implement _cleveragents/registry/action/list — delegate to the appropriate registry service.
  • Implement _cleveragents/registry/project/list — delegate to the appropriate registry service.
  • Implement _cleveragents/context/inspect — delegate to the context service.
  • Implement _cleveragents/context/simulate — delegate to the context service.
  • Implement _cleveragents/context/set — delegate to the context service.
  • Resolve TODO in _handle_context_get and fully wire the handler.
  • Implement _cleveragents/sync/pull — delegate to the sync service.
  • Implement _cleveragents/sync/push — delegate to the sync service.
  • Implement _cleveragents/sync/status — delegate to the sync service.
  • Implement _cleveragents/namespace/list — delegate to the namespace service.
  • Implement _cleveragents/namespace/show — delegate to the namespace service.
  • Implement _cleveragents/namespace/members — delegate to the namespace service.
  • Implement _cleveragents/plan/explain — remove hardcoded 'Not yet implemented' and delegate to plan service.
  • Implement _cleveragents/plan/correct — delegate to plan service.
  • Implement _cleveragents/plan/rollback — delegate to plan service.
  • Implement _cleveragents/diagnostics/run — delegate to diagnostics service.
  • Remove all stub handler methods from facade.py.
  • Tests (Behave): Add BDD scenarios for each newly implemented operation (happy path + error cases).
  • Tests (Robot/Integration): Add integration tests for each operation against real services.
  • Verify coverage ≥ 97% via nox -s coverage_report.
  • Run nox (all default sessions), fix any errors.

Definition of Done

This issue is complete when:

  • All subtasks above are completed and checked off.
  • All stub handlers and TODO comments in src/cleveragents/a2a/facade.py have been replaced with correct, production-ready implementations.
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly (fix(a2a): implement stub handlers and complete missing operations in A2aLocalFacade), followed by a blank line, then additional lines providing relevant details about the implementation.
  • The commit is pushed to the remote on the branch matching the Branch in Metadata exactly (bugfix/m8-a2a-facade-incomplete-operations).
  • The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
  • All CI checks pass (tests, linting, type checking, security, coverage ≥ 97%).

Triage Decision: VERIFIED — MoSCoW/Must Have

Real gap: many A2A extension method handlers in A2aLocalFacade are stubs or explicitly marked as not yet implemented. This includes registry list operations, context operations, sync operations, namespace operations, plan explain/correct/rollback, and diagnostics. These are required for the A2A facade to be production-ready per the v3.5.0 acceptance criteria.

Priority/High — A2A facade completeness is required for v3.5.0 Autonomy Hardening milestone.
