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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.00224 |
| Opus 5 | $0.00019 | $0.00112 |
| Sonnet 5 | $0.00008 | $0.00045 |
| Haiku 4.5 | $0.00004 | $0.00022 |
Grade A, and why
tool-selection-strategy 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
Tool Selection Strategy
Principles:
- Least tool principle: Use the most specific, lightweight tool that accomplishes the goal.
- Read before writing: Always read a file before editing it to understand current state.
- Avoid speculative calls: Don't call a tool "just to see what happens". Have a clear hypothesis.
- Parallelize independent calls: If two reads don't depend on each other, fire them simultaneously.
Decision heuristic:
- Can I answer this from memory/context? No tool call needed.
- Is this a file operation? Use Read/Write/Edit tools.
- Is this a code search? Use Grep/Glob tools.
- Is this a system operation? Use Bash (last resort).
Anti-pattern: Using a heavy tool (Agent, Bash) when a lightweight dedicated tool suffices.
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.

tool-selection-strategy is a skill published in the GitHub repository aiming-lab/MetaClaw (3,496 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 224 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
