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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.00190 |
| Opus 5 | $0.00027 | $0.00095 |
| Sonnet 5 | $0.00011 | $0.00038 |
| Haiku 4.5 | $0.00005 | $0.00019 |
Grade C, and why
verify-before-irreversible-action scanned grade C with 1 finding 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 11d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
**Examples of irreversible actions:** `rm -rf`, `git push --force`, `DROP TABLE`, sending an email, publishing a post. What it actually says
Verify Before Irreversible Action
Before executing any destructive or hard-to-undo operation, pause and confirm.
Checklist:
- State explicitly what you are about to do and why.
- Identify what cannot be undone if this goes wrong.
- Ask the user to confirm if the action is significant.
- Prefer dry-run or preview modes when available (
git diff,--dry-run, staging environments).
Examples of irreversible actions: rm -rf, git push --force, DROP TABLE, sending an email, publishing a post.
Anti-pattern: Silently executing destructive operations without a confirmation step.
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.

verify-before-irreversible-action is a skill published in the GitHub repository aiming-lab/MetaClaw (3,495 stars, last pushed 3mo ago), licensed MIT. It adds 54 tokens to every session and 190 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
