Metadata

  • Commit Message: feat(a2a): A2A facade session and plan lifecycle operations functional via CLI
  • Branch: feature/m6-a2a-facade-cli

Background

M6 (v3.5.0) acceptance criterion: the A2A local facade must support session and plan lifecycle operations that are fully functional via the CLI. Per the testing spec (docs/development/testing.md lines 1446-1558), the A2A Local Facade supports 11 operations including session management, plan lifecycle, and agent discovery.

Per the E2E suite (m6_e2e_verification.robot), tests verify: creating porting actions from YAML config (line 17), executing plans on large projects (line 28), plan apply via lifecycle CLI (line 83), and decision tree structure (line 114).

Expected Behavior

  1. agents session CLI commands work through the A2A facade
  2. Plan lifecycle operations (use, execute, apply) route through the A2A facade
  3. A2A facade supports all 11 documented operations in local mode
  4. Session state persists across CLI invocations
  5. Plan lifecycle transitions are validated by the facade

Acceptance Criteria

  • A2A facade routes session operations correctly
  • Plan lifecycle (use, execute, apply) works through A2A facade via CLI
  • All 11 A2A Local Facade operations functional
  • Robot E2E tests for action creation, plan execution, and plan apply pass
  • Unit tests cover: session create/resume, plan lifecycle through facade, error handling

Supporting Information

  • E2E tests: robot/m6_e2e_verification.robot lines 17, 28, 83, 114
  • Testing spec: docs/development/testing.md lines 1446-1558
  • ADR-047 (A2A Standard Adoption), ADR-048 (Server Architecture)

Subtasks

  • Implement A2A local facade session operations
  • Wire plan lifecycle CLI commands through A2A facade
  • Implement all 11 A2A facade operations
  • Add session state persistence
  • Tests (Behave): Add scenarios for facade operations
  • Tests (Robot): Verify E2E acceptance tests pass
  • Verify coverage >=97% via nox -s coverage_report
  • Run nox (all default sessions), fix any errors

Implementation Notes — Day 37

Approach: Facade Notification Pattern

Rather than rewriting all CLI commands to be facade-first (which would risk breaking existing tests and behavior), adopted a notification pattern: CLI commands perform the primary work via direct service calls, then notify the A2A facade for protocol compliance. This preserves backward compatibility while establishing the A2A data flow.

Key Code Locations

  • src/cleveragents/a2a/cli_bootstrap.py — Facade construction and caching (commit 99fd8454)
  • src/cleveragents/cli/commands/session.py — Facade notification in create command
  • src/cleveragents/cli/commands/plan.py_notify_facade() helper, notifications in use/execute/apply

Quality Gates

  • Lint: | Typecheck: 0 errors | Unit tests: 385 features, 11113 scenarios | Integration: all passed | Coverage: 97%
