Background

Part of Epic #5168 (Context CLI Commands). The agents context CLI commands need robust error handling: invalid project names, missing context configurations, budget constraint violations, and filesystem errors must all produce clear, actionable error messages rather than raw exceptions.

Expected Behavior

  • agents context add with an invalid project name shows a clear error
  • agents context show when no context is configured shows a helpful message
  • agents context clear on a non-existent project shows a clear error
  • agents context inspect when tier storage is unavailable shows a degraded-mode message
  • All errors exit with non-zero exit code
  • All errors produce Rich-formatted error panels (or JSON error objects with --format json)

Acceptance Criteria

  • agents context add validates project name format before calling service layer
  • agents context show handles ContextNotFoundError gracefully
  • agents context clear handles missing project gracefully
  • agents context inspect handles unavailable tier storage gracefully
  • All error paths exit with code 1
  • Error messages include actionable guidance (e.g., "Run agents context add first")
  • --format json produces {"error": "...", "code": "..."} on error
  • Pyright strict mode passes

Metadata

  • Branch: feat/v3.4.0/context-cli-error-handling
  • Commit Message: feat(context): implement robust error handling for agents context commands
  • Milestone: v3.4.0
  • Parent Epic: #5168

Subtasks

  • Define ContextCliError hierarchy in context CLI module
  • Add argument validation to context add (project name, policy format)
  • Add ContextNotFoundError handling to context show
  • Add missing-project handling to context clear
  • Add tier-unavailable handling to context inspect
  • Implement JSON error response format
  • Write Behave scenarios for all error paths
  • Verify exit codes in integration tests

Definition of Done

  • All subtasks completed
  • All Behave error scenarios pass
  • nox passes with coverage >= 97%
  • No raw exceptions leak to CLI output

The `agents context` CLI commands need robust error handling: invalid project names, missing context configurations, budget constraint violations, and filesystem errors must all produce clear, actionable error messages rather than raw exceptions. ## Expected Behavior - `agents context add` with an invalid project name shows a clear error - `agents context show` when no context is configured shows a helpful message - `agents context clear` on a non-existent project shows a clear error - `agents context inspect` when tier storage is unavailable shows a degraded-mode message - All errors exit with non-zero exit code - All errors produce Rich-formatted error panels (or JSON error objects with `--format json`) ## Acceptance Criteria - [ ] `agents context add` validates project name format before calling service layer - [ ] `agents context show` handles `ContextNotFoundError` gracefully - [ ] `agents context clear` handles missing project gracefully - [ ] `agents context inspect` handles unavailable tier storage gracefully - [ ] All error paths exit with code 1 - [ ] Error messages include actionable guidance (e.g., "Run `agents context add` first") - [ ] `--format json` produces `{"error": "...", "code": "..."}` on error - [ ] Pyright strict mode passes ## Metadata - **Branch**: `feat/v3.4.0/context-cli-error-handling` - **Commit Message**: `feat(context): implement robust error handling for agents context commands` - **Milestone**: v3.4.0 - **Parent Epic**: #5168 ## Subtasks - [ ] Define `ContextCliError` hierarchy in context CLI module - [ ] Add argument validation to `context add` (project name, policy format) - [ ] Add `ContextNotFoundError` handling to `context show` - [ ] Add missing-project handling to `context clear` - [ ] Add tier-unavailable handling to `context inspect` - [ ] Implement JSON error response format - [ ] Write Behave scenarios for all error paths - [ ] Verify exit codes in integration tests ## Definition of Done - [ ] All subtasks completed - [ ] All Behave error scenarios pass - [ ] `nox` passes with coverage >= 97% - [ ] No raw exceptions leak to CLI output --- **Automated by CleverAgents Bot** Supervisor: Epic Planner | Agent: epic-planning-pool-supervisor
