/implement Command

WHAT: Execute implementation phases with test-first enforcement and agent coordination.

HOW: Detects issue type, follows its workflow, enforces quality gates.

Usage

/implement 001 1.1         # Execute specific phase (detects type from file)
/implement 003 2.2         # Execute bug fix phase
/implement 005             # Spike: asks which plan, creates spike branch
/implement 001 --next      # Auto-find next uncompleted phase
/implement --next          # Auto-detect issue + next phase
/implement 001 --full      # Execute all remaining phases
/implement PROJ-123 --next # Jira issue

Issue Type Detection

Reads issue file to determine type and workflow:

# In pm/issues/###-name/ directory:
if [ -f "TASK.md" ]; then type="task"    # TDD phases
elif [ -f "BUG.md" ]; then type="bug"    # Reproduction-first
elif [ -f "SPIKE.md" ]; then type="spike" # Exploration plans
fi
Issue File Workflow Branch Pattern
TASK.md TDD (RED/GREEN/REFACTOR) feature/###
BUG.md Reproduction-first bugfix/###
SPIKE.md Exploration (per plan) spike/###/plan-N

Execution Flow

1. Parse & Validate

  • Parse issue ID and phase (or auto-detect)
  • Locate issue directory: pm/issues/{ID}-*/
  • Read issue file (TASK.md/BUG.md/SPIKE.md)
  • Read PLAN.md (or PLAN-N.md for spikes)
  • Create WORKLOG.md if missing (with Phase Commits header)

2. Type-Specific Handling

For TASK/BUG:

  • Create feature/bugfix branch if needed
  • Execute phase with TDD checkpoints
  • Follow quality gates per workflow

For SPIKE (see below):

  • Ask which plan to explore
  • Create spike branch
  • Execute without quality gates

3. Agent Coordination

Select agent based on phase domain:

  • frontend-specialist, backend-specialist, database-specialist
  • test-engineer for RED phases
  • code-reviewer for REFACTOR phases

4. TDD Checkpoints (TASK/BUG)

  • RED: Tests FAIL before implementation
  • GREEN: Tests PASS after implementation
  • REFACTOR: Review ≥90 to complete

5. Track Progress

  • Write WORKLOG entry
  • Update Phase Commits section
  • Check off PLAN.md checkbox
  • Commit changes

SPIKE Implementation

When issue type is SPIKE, behavior changes significantly.

Step 1: Select Plan

Which plan do you want to explore?

Available plans:
  1. PLAN-1.md: GraphQL with Apollo Server
  2. PLAN-2.md: REST with Express

Enter plan number: _

Step 2: Create Spike Branch

# From current branch (usually develop)
git checkout -b spike/005/plan-1

Step 3: Execute Exploration

Differences from TASK/BUG:

Aspect TASK/BUG SPIKE
TDD checkpoints Required Not enforced
Code review Required (≥90) Not required
Commits To feature branch To spike branch
WORKLOG WORKLOG.md WORKLOG-N.md
Branch merge Yes (to develop) Never

Step 4: Track Findings

  • Update WORKLOG-N.md on spike branch
  • Document discoveries, surprises, benchmarks
  • Track time spent vs time box

Example SPIKE Flow

User: /implement 005

AI: Issue 005 (spike): "GraphQL vs REST for our API?"

    Which plan do you want to explore?
    1. PLAN-1.md: GraphQL with Apollo Server
    2. PLAN-2.md: REST with Express

User: 1

AI: Creating branch spike/005/plan-1...

    > ⚠️ SPIKE EXPLORATION
    > Code will be committed to spike branch, not merged to main.
    > Track discoveries in WORKLOG-1.md.

    Executing PLAN-1.md Phase 1: Setup
    → Installing Apollo Server...
    → Creating basic schema...
    → Updating WORKLOG-1.md

    ✓ Phase 1 complete (1.5 hours spent, 6.5 remaining)

    Continue to Phase 2? (yes/no/stop)

Task-Specific Scripts

Temporary scripts go in task directory:

pm/issues/001-user-auth/
├── TASK.md
├── PLAN.md
├── WORKLOG.md
└── scripts/
    ├── generate-test-users.sh
    ├── migrate-passwords.js
    └── debug-jwt-validation.js

Why: Easy cleanup, clear context, no root clutter.

Root scripts/: Only for universal utilities used across tasks.


Modes

Mode Command Behavior
Specific /implement 001 1.1 Execute single phase
Next /implement 001 --next Find first uncompleted
Full /implement 001 --full Execute all remaining
Auto /implement --next Auto-detect issue + next

Example (TASK)

User: /implement 001 --next

AI: Next: 1.RED - Write failing tests for user login
    Proceed? (yes/no)

User: yes

AI: Spawning test-engineer...
    → Tests written (8 test cases)
    → Running tests...
    → [RED CHECKPOINT] 8 tests FAILED ✓
    ✓ Phase 1.RED complete

    Next: /implement 001 --next

Error Handling

Error Resolution
Issue not found Check pm/issues/{ID}-*/ exists
PLAN.md missing Run /plan {ID} first
Unknown type Verify TASK.md/BUG.md/SPIKE.md exists
Spike no plans Run /plan ### to create plans
Phase complete Use --next for next phase

Integration

/issue → /plan ### → /implement ### → /complete ### → /branch merge

SPIKE flow:

/issue → /plan ### → /implement ### → /complete ###
                         ↓
               (creates spike branch)
                         ↓
               (never merges to develop)
