Phase: Implementation

Execute a single implementation plan.

Arguments

$ARGUMENTS - Path to the plan file (e.g., plans/workflow-1-setup-auth.md)

Steps

1. Read Plan File

Read the plan file to understand:

• Tasks to implement
• Dependencies
• Acceptance criteria
• GitHub issue number

2. Execute Implementation

Invoke the sdlc implement skill:

/sdlc:implement $ARGUMENTS

This will:

• Execute the plan in TDD mode (if configured)
• Create commits for each significant change
• Run tests to verify implementation
• Link commits to the GitHub issue

3. Verify Implementation

After implementation:

• Check all tests pass
• Verify no linting errors
• Confirm changes match plan requirements

4. Update Progress File

Mark the plan as completed:

- [x] $ARGUMENTS (issue: #N)

Increment the completed count.

5. Emit Signal

For individual plan completion:

<plan>PLAN_N_COMPLETE</plan>

After ALL plans are done:

<phase>IMPLEMENTATION_COMPLETE</phase>

Decision Logic

• If this is the last plan → emit IMPLEMENTATION_COMPLETE
• If more plans remain → emit PLAN_N_COMPLETE where N is the plan number

Check the progress file to determine:

completed: X
total: Y

If X == Y after this plan, this is the last one.

Error Handling

If implementation fails:

<promise>FAILED</promise>
<error>Implementation failed: {reason}</error>

Output Format

On success (not last plan):

Plan implemented successfully: $ARGUMENTS

Changes:
- Created src/auth/login.ts
- Added tests in tests/auth/login.test.ts
- Updated routes in src/routes.ts

<plan>PLAN_1_COMPLETE</plan>

On success (last plan):

Plan implemented successfully: $ARGUMENTS

All plans complete!
<plan>PLAN_3_COMPLETE</plan>
<phase>IMPLEMENTATION_COMPLETE</phase>
