MemoryAI — A Brain for Your AI Agent 🧠

Every AI session starts from zero. Yours doesn't have to.

You spend 2 hours explaining your codebase, your preferences, your architecture decisions. The session ends. Tomorrow? Your AI has amnesia. You start over. Again.

MemoryAI fixes this permanently. It gives your AI agent a real long-term memory — one that remembers what you built, what you decided, what you prefer, and why. Not for hours. For weeks, months, even years.

See it in action:

Monday: "Our API uses /v1/ prefix, TypeScript with 2-space tabs, and we deploy via GitHub Actions."

3 weeks later: You say "write a new endpoint." Your AI already knows the prefix, the style, the pipeline. Zero repetition. It just remembers.

Your AI's memory works like yours:

• 🔥 Hot — Daily drivers: active projects, current preferences. Instant recall, always sharp.
• 🌤️ Warm — Important context: past decisions, completed tasks. Fades gently, snaps back when needed.
• ❄️ Cold — Deep archive: old projects, historical conversations. Never deleted, always searchable.

The more your AI uses a memory, the sharper it stays. Unused memories age into cold storage — but a single recall brings them right back. Just like the human brain.

Zero dependencies. Pure Python stdlib. Every line of source code is readable, auditable, and yours to inspect.

What's new:

• v1.0.0 — Context Guard v4: reads token usage directly from OpenClaw. No API dependency, cross-platform.
• v0.5.0 — Zero-gap session handoff: switch sessions without losing a single thought.

Setup

1. Get API key from https://memoryai.dev (free tier available)
2. Edit {baseDir}/config.json:

{
  "endpoint": "https://memoryai.dev",
  "api_key": "hm_sk_your_key_here"
}

Or set env vars: HM_ENDPOINT and HM_API_KEY.

3. Test: python {baseDir}/scripts/client.py stats

Commands

Store memory

python {baseDir}/scripts/client.py store -c "data to remember" -t "tag1,tag2" -p hot

Priority: hot (important, frequent recall) | warm (default) | cold (archive)

Optional parameters:

• --memory-type \x3Ctype> — fact, decision, preference, error, goal, episodic
• --retention \x3Cpolicy> — forever, 6m, 1y, auto (default)

Recall memory

python {baseDir}/scripts/client.py recall -q "what was discussed?" -d deep

Depth controls how hard the brain tries to remember:

• fast — Quick surface recall
• deep — Thorough search, connecting related ideas
• exhaustive — Deep concentrated effort

Stats

python {baseDir}/scripts/client.py stats

Compact (consolidate memories)

python {baseDir}/scripts/client.py compact -c "session transcript or context" -t "task description"

Like how the brain consolidates memories during sleep — distills a long session into key memories.

Restore context

python {baseDir}/scripts/client.py restore -t "what I was working on"

Wake up with full context for your current task.

Check context health

python {baseDir}/scripts/client.py check

Returns urgency: low | medium | high | critical

Reflect (auto-reflection)

python {baseDir}/scripts/client.py reflect --hours 24 --max-insights 5

Finds recurring patterns in recent memories and creates insight chunks.

Session Handoff (v0.5.0)

Zero-gap session switching — when context window fills up, seamlessly transition to a new session without losing any context.

How it works:

1. Old session sends its conversation to your configured MemoryAI endpoint (HTTPS)
2. New session retrieves the old conversation + related long-term memories from the same endpoint
3. Once the new session has enough context, the old session is archived into long-term storage

Start handoff (save old session)

python {baseDir}/scripts/client.py handoff-start -c '[{"role":"user","content":"..."},{"role":"assistant","content":"..."}]'

Or pipe from stdin:

echo '[ ... conversation ... ]' | python {baseDir}/scripts/client.py handoff-start

Restore handoff (new session reads old session)

python {baseDir}/scripts/client.py handoff-restore

Returns the old session conversation + related MemoryAI memories.

Options:

• --no-memories — Skip related MemoryAI memories
• --memory-limit N — Max related memories (default: 5)

Complete handoff (archive old session)

python {baseDir}/scripts/client.py handoff-complete

Archives the old session conversation into long-term MemoryAI storage and marks the handoff as done.

Check handoff status

python {baseDir}/scripts/client.py handoff-status

Returns whether there's an active handoff and its state.

Context Guard (Optional)

Background job to automatically monitor and compact memory when context gets too large.

To enable, ask the user for permission first, then create a cron job:

• Name: context-guard
• Schedule: every 15 minutes (everyMs: 900000)
• Session: isolated
• Delivery: none
• Payload (agentTurn):

Run context check: python {baseDir}/scripts/client.py check
If urgency is 'high' or 'critical': run python {baseDir}/scripts/client.py compact -c "auto context guard backup" -t "context-guard"
Reply NO_REPLY.

Important: Always ask the user before creating the cron job.

When to Use

Memory Lifecycle

Store → Active (hot) → Aging (warm) → Archive (cold)
         ↑                                    |
         └──── recalled = strengthened ───────┘

Rules

• Recall only when the user asks about past work, previous decisions, or you need context you don't already have in this session
• Do NOT recall on every message — only when relevant past context is actually needed
• Store important outcomes after completing tasks (not after every message)
• Present memories naturally — integrate recalled information into your responses rather than showing raw API output
• Ask for user permission before enabling context guard or any background tasks
• Use handoff commands transparently — session management runs in the background

Platform Compatibility

All core memory features work on any platform that can run Python 3.10+:

On IDE platforms (Cursor, VS Code, Claude Code, Windsurf, Antigravity):

• All memory commands work via client.py CLI
• Session handoff can be triggered manually when context gets large
• Context Guard is not available (requires OpenClaw cron system)

On OpenClaw:

• Full feature set including Context Guard and automatic session switching
• Context Guard uses OpenClaw's cron system for periodic health checks

Data & Privacy

What this skill reads locally:

• context_check.py reads OpenClaw's sessions.json (under OPENCLAW_DIR, defaults to ~/.openclaw) to check token usage for Context Guard.
• A small WAL file is written to WORKSPACE/memory/wal.json to track session handoff state.
• OPENCLAW_DIR and WORKSPACE are optional env vars — they default to ~/.openclaw and ~/.openclaw/workspace respectively.

What this skill sends externally:

• store, compact, handoff-start: sends user-provided content (memories, session transcripts) to the configured HM_ENDPOINT via HTTPS.
• recall, restore, handoff-restore: retrieves previously stored data from the same endpoint.
• No data is sent automatically — all transmissions require explicit CLI invocation or agent action.

Privacy controls:

• All data is transmitted over encrypted HTTPS connections and stored in isolated, private databases.
• Users can export all data via /v1/export and delete all data via DELETE /v1/data at any time.
• client.py uses only Python stdlib (urllib) — no third-party dependencies. Source is fully readable and auditable.
