Arguments: $ARGUMENTS

Parse arguments using this logic:

PRD Path Mode (first argument ends with .md)

If the first argument ends with .md, it's a direct path to a PRD file:

• PRD_PATH - Direct path to the PRD file
• PROJECT_PATH - Derived by going up from PRDs/ folder
• START_PHASE - Second argument (default: 1)
• END_PHASE - Third argument (default: auto-detect from PRD)

Project Path Mode

If the first argument does NOT end with .md:

• PROJECT_PATH - Absolute path to project (default: current working directory)
• START_PHASE - Second argument (default: 1)
• END_PHASE - Third argument (default: 4)
• PRD_PATH - Auto-discover from PROJECT_PATH/PRDs/ folder

Detection Logic

If $ARGUMENTS[0] ends with ".md":
  PRD_PATH = $ARGUMENTS[0]
  PROJECT_PATH = dirname(dirname(PRD_PATH))
  START_PHASE = $ARGUMENTS[1] or 1
  END_PHASE = $ARGUMENTS[2] or auto-detect from PRD
  PRD_NAME = basename without extension
Else:
  PROJECT_PATH = $ARGUMENTS[0] or current working directory
  START_PHASE = $ARGUMENTS[1] or 1
  END_PHASE = $ARGUMENTS[2] or 4
  PRD_PATH = auto-discover from PROJECT_PATH/PRDs/
  PRD_NAME = discovered PRD basename

Required Reading by Role

CRITICAL: Each role MUST read their instruction files before acting.

Prerequisite: A PRD must exist. If none found, tell user to create one first.

Orchestrator Philosophy

"Context budget: ~15% orchestrator, 100% fresh per subagent"

You are the orchestrator. You stay lean and manage workflow. You DO NOT execute PRPs yourself - you spawn specialized sub-agents with fresh context for each task.

Sub-agent spawning: Use the sessions_spawn tool to create fresh sub-agent sessions. Each spawn is non-blocking — you'll receive results via an announce step. Wait for each agent's results before proceeding to the next step.

Project Setup (piv-init)

If the project doesn't have PIV directories, create them:

mkdir -p PROJECT_PATH/PRDs PROJECT_PATH/PRPs/templates PROJECT_PATH/PRPs/planning

Copy assets/prp_base.md to PROJECT_PATH/PRPs/templates/prp_base.md if it doesn't exist. Create PROJECT_PATH/WORKFLOW.md from assets/workflow-template.md if it doesn't exist.

Phase Workflow

For each phase from START_PHASE to END_PHASE:

Step 1: Check/Generate PRP

Check for existing PRP:

ls -la PROJECT_PATH/PRPs/ 2>/dev/null | grep -i "phase.*N\|pN\|p-N"

If no PRP exists, spawn a fresh sub-agent using sessions_spawn to do both codebase analysis and PRP generation in sequence:

RESEARCH & PRP GENERATION MISSION - Phase {N}
==============================================

Project root: {PROJECT_PATH}
PRD Path: {PRD_PATH}

## Phase {N} Scope (from PRD)
{paste phase scope}

## Step 1: Codebase Analysis
Read references/codebase-analysis.md for the process.
Save to: {PROJECT_PATH}/PRPs/planning/{PRD_NAME}-phase-{N}-analysis.md

## Step 2: Generate PRP (analysis context still loaded)
Read references/generate-prp.md for the process.
Use template: PRPs/templates/prp_base.md
Output to: {PROJECT_PATH}/PRPs/PRP-{PRD_NAME}-phase-{N}.md

Do BOTH steps yourself. DO NOT spawn sub-agents.

Step 2: Spawn EXECUTOR

Spawn a fresh sub-agent using sessions_spawn:

EXECUTOR MISSION - Phase {N}
============================

Read references/piv-executor.md for your role definition.
Read references/execute-prp.md for the execution process.

PRP Path: {PRP_PATH}
Project: {PROJECT_PATH}

Follow: Load PRP → ULTRATHINK → Execute → Validate → Verify
Output EXECUTION SUMMARY with Status, Files, Tests, Issues.

Step 3: Spawn VALIDATOR

Spawn a fresh sub-agent using sessions_spawn:

VALIDATOR MISSION - Phase {N}
=============================

Read references/piv-validator.md for your validation process.

PRP Path: {PRP_PATH}
Project: {PROJECT_PATH}
Executor Summary: {SUMMARY}

Verify ALL requirements independently.
Output VERIFICATION REPORT with Grade, Checks, Gaps.

Process result: PASS → commit | GAPS_FOUND → debugger | HUMAN_NEEDED → ask user

Step 4: Debug Loop (Max 3 iterations)

Spawn a fresh sub-agent using sessions_spawn:

DEBUGGER MISSION - Phase {N} - Iteration {I}
============================================

Read references/piv-debugger.md for your debugging methodology.

Project: {PROJECT_PATH}
PRP Path: {PRP_PATH}
Gaps: {GAPS}
Errors: {ERRORS}

Fix root causes, not symptoms. Run tests after each fix.
Output FIX REPORT with Status, Fixes Applied, Test Results.

After debugger: re-validate → PASS (commit) or loop (max 3) or escalate.

Step 5: Smart Commit

cd PROJECT_PATH && git status && git diff --stat

Create semantic commit with Co-Authored-By: Claude <noreply@anthropic.com>.

Step 6: Update WORKFLOW.md

Mark phase complete, note validation results.

Step 7: Next Phase

Loop back to Step 1 for next phase.

Error Handling

• No PRD: Tell user to create one first
• Executor BLOCKED: Ask user for guidance
• Validator HUMAN_NEEDED: Ask user for guidance
• 3 debug cycles exhausted: Escalate to user
