README

Pi Verify - Auto-Verification for Pi

Two-agent system: builder runs, verifier checks, auto-corrects.

Inspired by disler/the-verifier-agent

Why

Tokens are cheap. Your time is not.

Manual review takes 50% of your day. pi-verify moves that to a second agent.

How It Works

BUILDER (pi) ──► session.jsonl ──► VERIFIER (pi)
    ▲                                    │
    │        sendUserMessage()            │
    └────────────────────────────────────┘
  1. Builder Pi runs in your terminal
  2. Verifier Pi watches the session
  3. After each turn, auto-checks:
    • Files created exist
    • Syntax valid
    • Tests pass
    • No dangerous commands
  4. If issues → feedback loop (max 3x)
  5. Still failing → human escalation

Confidence Grades

Grade Meaning
PERFECT All checks pass
VERIFIED Minor suggestions
PARTIAL Some issues
FAILED Major problems

Installation

npm install @artale/pi-verify

Usage

# Enable verification
/verify on

# Check status
/verify status

# Disable
/verify off

Architecture

  • Extension: ./src/extension.ts - Pi integration
  • Script: verify.sh - Unix socket watcher
  • Config: MAX_LOOPS=3 - Loop limit

The Pattern

  1. Defense in depth bash
  2. Deterministic session.jsonl
  3. Read-only verifier tools
  4. Only verifier_prompt touches builder
  5. Max loops, then human escalation
