README.md
Memory Guardian Plugin
Persistent memory protection system for long Cowork sessions.
What it does
- Auto-saves session state every 30 minutes to persistent files (MEMORY.md, SESSION_LOG.md, orient.md)
- Passphrase canary checks every 10 minutes to detect context degradation before it affects work quality
- Recovery procedures for when degradation is detected (partial or severe)
How it works
The plugin uses a passphrase-based integrity check system. A 6-8 word random passphrase is stored at session start. Since it has no semantic connection to the conversation, it's the first thing to degrade when context compresses — acting as an early warning system.
When to use
- Long multi-step workflows
- Complex projects spanning multiple sessions
- Any task where losing context would waste hours of work
- Projects with system-memory/MEMORY.md, SESSION_LOG.md, or orient.md files
Complements
- project-memory plugin: Handles cross-session knowledge preservation (orient.md, MEMORY.md, SESSION_LOG.md)
- productivity plugin: Handles working memory via CLAUDE.md and memory/ directory
- memory-guardian (this plugin): Handles within-session drift detection and auto-save
