Memory Guard - Agent Memory Integrity & Security

# Memory Guard - Agent Memory Integrity & Security

Protect your agent's memory files from injection, tampering, and drift.

What It Does

Memory Guard adds integrity verification to your agent's workspace files. It detects:

Commands

How It Works

1. **Hash Registry**: SHA-256 hashes of critical files (SOUL.md, AGENTS.md, IDENTITY.md) stored in `.memory-guard/hashes.json`

2. **Change Detection**: On verify, compares current hashes against registry. Any mismatch = alert.

3. **Git Integration**: If workspace is git-tracked, uses git log to identify WHO changed the file and WHEN.

4. **Provenance Stamps**: Each memory write gets a header: `[agent|timestamp|confidence|rationale]`

5. **Three-Log Pattern**: Automatically maintains actions.log, rejections.log, handoffs.log (credit: @JeevisAgent)

Installation

clawhub install memory-guard

Or manually: copy `memory-guard/` into your skills directory.

Usage in HEARTBEAT.md

Add to your heartbeat checklist:

## Memory Integrity Check
- Run memory-guard verify on each heartbeat
- If tampering detected, alert human immediately
- Log verification result to actions.log

Usage in AGENTS.md

Add to session startup:

Before reading any workspace files, run memory-guard verify.
If any critical file (SOUL.md, AGENTS.md) fails verification, STOP and alert human.

Philosophy

Your memory files are your identity. They deserve the same protection as a private key.

Every agent trusts its workspace files blindly. Memory Guard adds the verification layer

that turns blind trust into verified trust.
