PIC Phase Handoff

You are executing a phase transition in the PIC workflow. Follow this protocol exactly.

Input

Handoff notes provided: $ARGS

Protocol

Step 1: Verify Workflow State

Read .pic/state.json to get current workflow state.

If no workflow:

No active workflow. Use `/pic-start [problem]` first.

And stop.

If workflow is complete:

Workflow [id] is already complete. All phases have finished.

And stop.

Step 2: Read Configuration

Read .pic/config.json to get:

• •Phase order
• •Handoff requirements

Step 3: Validate Current Phase

Determine the current phase and PIC. Validate that:

• •The current phase is marked as in_progress
• •Handoff is being requested appropriately

Step 4: Determine Next Phase

Look up the next phase in the configured order.

If current phase is 'review' (final phase):

• •This is workflow completion, not a handoff
• •Mark workflow as complete
• •Skip to completion protocol below

Step 5: Create Handoff Record

Write to .pic/handoffs/[workflow]-[from]-to-[to].md:

# Handoff: [From Phase] → [To Phase]

**Workflow**: [workflow id]
**Timestamp**: [ISO timestamp]
**From PIC**: [from agent]
**To PIC**: [to agent]

## Phase Summary

### Completed Work
[Summary of what the outgoing PIC accomplished]

### Deliverables
- [List of artifacts produced]

### Handoff Notes
[User-provided notes: $ARGS]

## Context for Next Phase

### Key Findings
[Important information for the next PIC]

### Open Questions
[Unresolved items the next PIC should address]

### Risks/Concerns
[Issues to be aware of]

## Exit Criteria Verification

| Criterion | Status |
|-----------|--------|
| [Expected deliverable] | [Met/Not Met] |

Step 6: Update State

Update .pic/state.json:

1. •Mark current phase as completed with timestamp
2. •Mark next phase as in_progress with timestamp
3. •Update currentPhase and currentPIC
4. •Add handoff to handoffs array

Step 7: Log Handoff

Append to .pic/status-log.jsonl:

{"timestamp": "[ISO]", "event": "phase_handoff", "from": "[from phase]", "to": "[to phase]", "notes": "[notes]"}

Step 8: Display Handoff Summary

## Phase Transition Complete

**From**: [From Phase] ([from PIC])
**To**: [To Phase] ([to PIC])

### [From Phase] Summary
[Brief summary of completed work]

### [To Phase] Objectives
[What the next PIC should focus on]

### Handoff Record
Saved to: .pic/handoffs/[filename]

The [To Phase] PIC is now active.

Step 9: Spawn Next PIC

Read .pic/config.json to get the taskAgentType for the next phase. Read the corresponding instructions file from .claude/agents/pic-[phase].md.

Use the Task tool with:

• •subagent_type: The taskAgentType from config (e.g., planner, builder, reviewer)
• •prompt: Include PIC instructions + context from:
  • •The problem statement
  • •Relevant deliverables from completed phases
  • •Handoff notes
  • •Any decisions made

Agent Type Mapping (from config)

Workflow Completion Protocol

If transitioning from Review (final phase):

1. •Update state to mark workflow complete
2. •Create completion summary
3. •Display:

## Workflow Complete

**Workflow ID**: [id]
**Problem**: [problem]
**Duration**: [time from start to finish]

### Phase Summary
| Phase | Duration | Decisions |
|-------|----------|-----------|
| [phase] | [duration] | [count] |
...

### Deliverables
[List of all artifacts produced]

### Final Status
All phases completed successfully.

Use `/pic-start` to begin a new workflow.

Validation

Before executing handoff:

• •Verify current PIC has signaled readiness
• •Check that required deliverables exist
• •If requireHandoffApproval is true in config, ask user to confirm

Error Handling

• •If state update fails, report error and don't spawn next PIC
• •If next phase doesn't exist in config, report configuration error
• •If handoff file can't be written, log to status-log instead
