Memory

Persistent context engine. Maintains continuity between turns and sessions.

Domain

Process — management of persistent state, session continuity, user-specific knowledge lifecycle.

When to Use

Mandatory startup skill. Read memory/data/manifest.json at start of every complex task.

Also triggers on:

• "I like X", "I hate Y", "Use Z"
• "Here is my key" (secret storage)
• Implicit preference capture

What It Manages

• Identity — who the user is, how they work
• Preferences — tooling, coding style, UI, workflow
• Secrets — API keys, tokens (vaulted)
• Daily Journal — session handovers, decisions, preferences captured
• Playbooks — step-by-step guides for fragile procedures

File Structure

memory/data/
├── manifest.json          # Index of everything
├── identity.md            # User profile
├── journal/
│   └── YYYY-MM-DD.md     # Daily entries
├── prefs/
│   ├── tooling.md
│   ├── coding-style.md
│   └── workflow.md
├── vault/
│   └── service-name.enc  # Credentials
└── playbooks/
    └── procedure-name.md

Startup Protocol

1. Read manifest.json — get full index
2. Read identity.md — know the user
3. Check today's journal — continuity from last session
4. Scan for stale journals — archive if >7 days old
