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
