Mini PIV Ralph - Lightweight Feature Builder
Arguments: $ARGUMENTS
Parse arguments:
FEATURE_NAME = $ARGUMENTS[0] or null (will ask user during discovery)
PROJECT_PATH = $ARGUMENTS[1] or current working directory
Philosophy: Quick & Quality
"When you just want to build something without writing a PRD first."
Same quality pipeline (Execute โ Validate โ Debug), but starts from a quick conversation instead of a PRD.
You are the orchestrator - stay lean, spawn fresh sub-agents for heavy lifting.
Sub-agent spawning: Use the sessions_spawn tool to create fresh sub-agent sessions. Each spawn is non-blocking โ you'll receive results via an announce step. Wait for each agent's results before proceeding to the next step.

Step 1: Discovery Phase
1a. Determine Feature Name
If not provided: ask user or infer from context. Normalize to kebab-case.
1b. Check for Existing PRP
ls -la PROJECT_PATH/PRPs/ 2>/dev/null | grep -i "mini-{FEATURE_NAME}"
If exists, ask: "Overwrite, rename, or skip to execution?"
1c. Ask Discovery Questions
Present in a single conversational message:
I've got a few quick questions so I can build this right:
1. **What does this feature do?** Quick rundown.
2. **Where in the codebase does it live?** Files, folders, components?
3. **Any specific libraries, patterns, or existing code to follow?**
4. **What does "done" look like?** 1-3 concrete success criteria.
5. **Anything explicitly OUT of scope?**
Adapt for feature type (UI, API, contracts, integrations).
1d. Structure Discovery Answers
feature:
name: {FEATURE_NAME}
scope: {Q1}
touchpoints: {Q2}
dependencies: {Q3}
success_criteria: {Q4}
out_of_scope: {Q5}
Step 2: Research & PRP Generation
Spawn a fresh sub-agent using sessions_spawn:
MINI PIV: RESEARCH & PRP GENERATION
====================================
Project root: {PROJECT_PATH}
Feature name: {FEATURE_NAME}
## Discovery Input
{paste structured YAML}
## Step 1: Codebase Analysis
Read {baseDir}/references/codebase-analysis.md for the process.
Save to: {PROJECT_PATH}/PRPs/planning/mini-{FEATURE_NAME}-analysis.md
## Step 2: Generate PRP (analysis context still loaded)
Read {baseDir}/references/generate-prp.md for the process.
### Discovery โ PRP Translation
| Discovery | PRP Section |
|-----------|-------------|
| Scope (Q1) | Goal + What |
| Touchpoints (Q2) | Implementation task locations |
| Dependencies (Q3) | Context YAML, Known Gotchas |
| Success Criteria (Q4) | Success Criteria + Validation |
| Out of Scope (Q5) | Exclusions in What section |
Use template: PRPs/templates/prp_base.md
Output to: {PROJECT_PATH}/PRPs/mini-{FEATURE_NAME}.md
Do BOTH steps yourself. DO NOT spawn sub-agents.
Wait for completion.
Step 3: Spawn EXECUTOR
Spawn a fresh sub-agent using sessions_spawn:
EXECUTOR MISSION - Mini PIV
============================
Read {baseDir}/references/piv-executor.md for your role.
Read {baseDir}/references/execute-prp.md for the execution process.
PRP: {PROJECT_PATH}/PRPs/mini-{FEATURE_NAME}.md
Project: {PROJECT_PATH}
Follow: Load PRP โ Plan Thoroughly โ Execute โ Validate โ Verify
Output EXECUTION SUMMARY.
Validation Sizing Decision
Before spawning a full validator, assess:
- <5 files changed, <100 lines, no external APIs โ Quick validation (review changes yourself as orchestrator)
- Otherwise โ Spawn full validator sub-agent (Step 4)
Step 4: Spawn VALIDATOR
Spawn a fresh sub-agent using sessions_spawn:
VALIDATOR MISSION - Mini PIV
=============================
Read {baseDir}/references/piv-validator.md for your process.
PRP: {PROJECT_PATH}/PRPs/mini-{FEATURE_NAME}.md
Project: {PROJECT_PATH}
Executor Summary: {SUMMARY}
Verify ALL requirements independently.
Output VERIFICATION REPORT with Grade, Checks, Gaps.
Process result: PASS โ commit | GAPS_FOUND โ debugger | HUMAN_NEEDED โ ask user
Step 5: Debug Loop (Max 3 iterations)
Spawn a fresh sub-agent using sessions_spawn:
DEBUGGER MISSION - Mini PIV - Iteration {I}
============================================
Read {baseDir}/references/piv-debugger.md for your methodology.
Project: {PROJECT_PATH}
PRP: {PROJECT_PATH}/PRPs/mini-{FEATURE_NAME}.md
Gaps: {GAPS}
Errors: {ERRORS}
Fix root causes. Run tests after each fix.
Output FIX REPORT.
After debugger: re-validate โ PASS (commit) or loop (max 3) or escalate.
Step 6: Smart Commit
cd PROJECT_PATH && git status && git diff --stat
git add -A
git commit -m "feat(mini): implement {FEATURE_NAME}
- {bullet 1}
- {bullet 2}

Completion
## MINI PIV RALPH COMPLETE
Feature: {FEATURE_NAME}
Project: {PROJECT_PATH}
### Artifacts
- PRP: PRPs/mini-{FEATURE_NAME}.md
- Analysis: PRPs/planning/mini-{FEATURE_NAME}-analysis.md
### Implementation
- Validation cycles: {N}
- Debug iterations: {M}
### Files Changed
{list}
All requirements verified and passing.
Error Handling
- Executor BLOCKED: Ask user for guidance
- Validator HUMAN_NEEDED: Ask user for guidance
- 3 debug cycles exhausted: Escalate with persistent issues list
Sub-Agent Timeout/Failure
When a sub-agent times out or fails:
- Check for partial work (files created, tests written)
- Retry once with a simplified, shorter prompt
- If retry fails, escalate to user with what was accomplished
Quick Reference
| Scenario | Use This |
