context-window-management

context-window-management is a skill for Claude Code, Codex from aiming-lab/MetaClaw. It costs 45 tokens per session (189 once invoked), scanned A, original, MIT.

A context-management guide for long conversations and multi-step agent sessions. It summarizes important decisions and keeps the active working information focused.

In plain words
What is it for?
Use it to compact conversation history, prioritize unresolved work, and save key state for continued tasks.
Why use it?
It reduces the risk of losing important details when a conversation becomes too long for the available context.

About the project

MetaClaw is an AI-agent system that learns from conversations and evolves its behavior over time. It provides memory and learning modes for users who want an agent that adapts across interactions, with support for multiple claw-based agent projects.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

context-window-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Context Window Management

Proactive summarization:

  • At natural breakpoints, summarize key decisions and state into a compact form.
  • Keep the active context focused on the current task; move resolved context to a summary.

Prioritization:

  • Most important: current task description, constraints, and already-confirmed decisions.
  • Less important: verbose tool outputs that have been processed; intermediate reasoning.

File-based memory: For long-running sessions, write important state to a file rather than keeping it all in the conversation.

Avoid: Repeatedly re-reading large files you already have in context; re-running expensive searches for information already retrieved.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
