Context Compactor

What this skill does

Token-based context compaction for local models (MLX, llama.cpp, Ollama) that don't report context limits.

Context Compactor is part of the Research & Knowledge category — research and knowledge skills that gather, search, and summarize information. You can install it on its own or alongside other research & knowledge skills from the OpenClaw catalog.

How to install Context Compactor

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for context-compactor and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add Context Compactor with a single command:

This pulls context-compactor from ClawHub and installs it into ~/.openclaw/skills/context-compactor/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use Context Compactor

Once installed, Context Compactor activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Manual install (advanced)
