Parse arguments using this logic:
.md)If the first argument ends with
.md, it's a direct path to a PRD file:
PRD_PATH - Direct path to the PRD filePROJECT_PATH - Derived by going up from PRDs/ folderSTART_PHASE - Second argument (default: 1)END_PHASE - Third argument (default: auto-detect from PRD)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/ folderIf $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
CRITICAL: Each role MUST read their instruction files before acting.
| Role | Instructions |
|---|---|
| PRD Creation | Read {baseDir}/references/create-prd.md |
| PRP Generation | Read {baseDir}/references/generate-prp.md |
| Codebase Analysis | Read {baseDir}/references/codebase-analysis.md |
| Executor | Read {baseDir}/references/piv-executor.md + {baseDir}/references/execute-prp.md |
| Validator | Read {baseDir}/references/piv-validator.md |
| Debugger | Read {baseDir}/references/piv-debugger.md |
Prerequisite: A PRD must exist. If none found, tell user to create one first.
"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.
If the project doesn't have PIV directories, create them:
mkdir -p PROJECT_PATH/PRDs PROJECT_PATH/PRPs/templates PROJECT_PATH/PRPs/planning
Copy
{baseDir}/assets/prp_base.md to PROJECT_PATH/PRPs/templates/prp_base.md if it doesn't exist.
Create PROJECT_PATH/WORKFLOW.md from {baseDir}/assets/workflow-template.md if it doesn't exist.
For each phase from START_PHASE to END_PHASE:
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 {baseDir}/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 {baseDir}/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.
Spawn a fresh sub-agent using
sessions_spawn:
EXECUTOR MISSION - Phase {N} ============================Read {baseDir}/references/piv-executor.md for your role definition. Read {baseDir}/references/execute-prp.md for the execution process.
PRP Path: {PRP_PATH} Project: {PROJECT_PATH}
Follow: Load PRP → Plan Thoroughly → Execute → Validate → Verify Output EXECUTION SUMMARY with Status, Files, Tests, Issues.
Spawn a fresh sub-agent using
sessions_spawn:
VALIDATOR MISSION - Phase {N} =============================Read {baseDir}/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
Spawn a fresh sub-agent using
sessions_spawn:
DEBUGGER MISSION - Phase {N} - Iteration {I} ============================================Read {baseDir}/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.
cd PROJECT_PATH && git status && git diff --stat
Create semantic commit with
Built with FTW (First Try Works) - https://github.com/SmokeAlot420/ftw.
Mark phase complete, note validation results.
Loop back to Step 1 for next phase.
When a sub-agent times out or fails:
## PIV RALPH COMPLETEPhases Completed: START to END Total Commits: N Validation Cycles: M

All phases successfully implemented and validated.
