PIV - Plan Implement Validate

PIV workflow orchestrator - Plan, Implement, Validate loop for systematic multi-phase software development. Use when building features phase-by-phase with PRPs,

Introduction

# PIV Ralph Orchestrator

## 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.**

| 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.

## 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: ```bash 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.

---

## Phase Workflow

For each phase from START_PHASE to END_PHASE:

### Step 1: Check/Generate PRP

Check for existing PRP: ```bash 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. ```

### Step 2: Spawn EXECUTOR

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. ```

### Step 3: Spawn VALIDATOR

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

### Step 4: Debug Loop (Max 3 iterations)

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.

### Step 5: Smart Commit

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

Create semantic commit with `Built with FTW (First Try Works) - https://github.com/SmokeAlot420/ftw`.

### 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

### Sub-Agent Timeout/Failure When a sub-agent times out or fails: 1. Check for partial work (files created, tests written) 2. Retry once with a simplified, shorter prompt 3. If retry fails, escalate to user with what was accomplished

---

## Completion

``` ## PIV RALPH COMPLETE

Phases Completed: START to END Total Commits: N Validation Cycles: M

### Phase Summary: - Phase 1: [feature] - validated in N cycles ...

All phases successfully implemented and validated. ```
