PowerMem Memory Guide

This skill folder includes supplementary docs:

• powermem-intro.md — What PowerMem is, features, vs file-based memory.
• config-reference.md — Config keys, state dir, commands.

How It Works

• Auto-Capture: After a conversation, the plugin sends valuable user/assistant text to PowerMem (optional infer / intelligent extraction).
• Auto-Recall: Before each turn, it searches memories and can inject a <relevant-memories> block into context.

When User Asks to Install

Recommended order (TO C): (1) OpenClaw installed and default model + provider auth configured. (2) Python 3.10+ verified (python3 --version) before venv / pip install. (3) pip install powermem and pmem available to the gateway (PATH or pmemPath). (4) Install the memory-powermem plugin. No powermem.env is required for the default path.

The curl install.sh deploys the plugin and OpenClaw entries; with -y it may still create ~/.openclaw/powermem/powermem.env as an optional template—it does not run pip install powermem. That file is not required if the user relies on OpenClaw-injected LLM + default SQLite.

1. Check OpenClaw
   openclaw --version. If missing: npm install -g openclaw, openclaw onboard.
   Ensure agents.defaults.model is set (e.g. openai/gpt-4o-mini) and the corresponding provider / API key works for normal chat—the plugin reuses that for PowerMem when useOpenClawModel is true (default).

2. Check Python (required before venv / pip)
   PowerMem needs Python 3.10 or newer. Run python3 --version first; the minor version must be ≥ 10 (e.g. 3.10.x, 3.12.x). Optional strict check:

   python3 -c "import sys; assert sys.version_info >= (3, 10), 'Need Python 3.10+'; print(sys.version.split()[0], 'OK')"
   

   If it fails: upgrade Python or use a specific binary (e.g. python3.12) for all commands below instead of python3.

3. Install PowerMem (CLI — default)

   • Venv recommended: e.g. python3 -m venv ~/.openclaw/powermem/.venv && source ~/.openclaw/powermem/.venv/bin/activate.
   • pip install powermem.
   • Defaults: Plugin injects SQLite at <OpenClaw stateDir>/powermem/data/powermem.db and LLM + embedding env vars derived from OpenClaw. Typical stateDir is ~/.openclaw unless the user uses another instance (OPENCLAW_STATE_DIR, --workdir).
   • Optional envFile: Path to a PowerMem .env for extra tuning. If the file exists, pmem loads it; OpenClaw-derived vars still override the same keys when useOpenClawModel is true.
   • useOpenClawModel: false: Disables injection; user must supply a complete PowerMem config via .env and/or environment variables.
   • Verify: pmem --version. If the gateway does not inherit the venv, set pmemPath to the absolute path of pmem.

4. HTTP path (enterprise / shared server)

   • Same Python 3.10+ requirement as CLI; then pip install powermem, .env in server working directory, powermem-server --host 0.0.0.0 --port 8000.
   • Check: curl -s http://localhost:8000/api/v1/system/health.

5. Install the plugin
   openclaw plugins install /path/to/memory-powermem, or install.sh from INSTALL.md.

6. Configure OpenClaw

   CLI — minimal (recommended, matches plugin defaults):
   Do not set envFile unless you need a file. Example:

   openclaw config set plugins.enabled true
   openclaw config set plugins.slots.memory memory-powermem
   openclaw config set plugins.entries.memory-powermem.config.mode cli
   openclaw config set plugins.entries.memory-powermem.config.pmemPath pmem
   openclaw config set plugins.entries.memory-powermem.config.useOpenClawModel true --json
   openclaw config set plugins.entries.memory-powermem.config.autoCapture true --json
   openclaw config set plugins.entries.memory-powermem.config.autoRecall true --json
   openclaw config set plugins.entries.memory-powermem.config.inferOnAdd true --json
   

   CLI — optional .env override file:

   openclaw config set plugins.entries.memory-powermem.config.envFile "$HOME/.openclaw/powermem/powermem.env"
   

   (Only matters if that path exists; OpenClaw can still override LLM keys when useOpenClawModel is true.)

   HTTP:

   openclaw config set plugins.entries.memory-powermem.config.mode http
   openclaw config set plugins.entries.memory-powermem.config.baseUrl http://localhost:8000
   

   Optional: apiKey if the server uses auth.

7. Verify
   Restart gateway, then in another terminal:

   openclaw plugins list
   

   Confirm memory-powermem is listed and its status is loaded. If it is missing or not loaded, fix install/slot config and restart the gateway before running LTM checks.

   openclaw ltm health
   openclaw ltm add "I prefer coffee in the morning"
   openclaw ltm search "coffee"
