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 | $0.00065 | $0.00989 |
| Opus 5.5 | $0.00026 | $0.00396 |
| Sonnet 5.5 | $0.00013 | $0.00198 |
| Haiku 4.5 | $0.00006 | $0.00099 |
Grade A, and why
clause-library scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clause Library
Build or extend a library of approved contract clauses for "$ARGUMENTS". Provide multiple versions of each clause type with jurisdiction considerations and usage guidance.
Note: AI-generated legal content does not constitute legal advice. All clauses should be reviewed by a qualified attorney before use in binding agreements.
Arguments. $ARGUMENTS may contain the project name and optional flags. Take the first token as <project> and treat --skip-checks as a flag; never include flags in file paths. All paths below use <project>. If --skip-checks is present, skip the prerequisite check and, before writing any artifact, append one line to .metapowers/legal/<project>/skip-log.md: - <ISO timestamp> — <skill name> skipped prerequisite check for <artifact file> — reason: <reason or "none given">.
Prerequisites
None — this is a utility skill.
Process
-
Determine scope:
- Parse "" to identify which clause types or contract context to focus on
- If a clause library already exists at
.metapowers/legal/<project>/clause-library.md, read it and extend rather than replace
-
Organize clauses by type:
- Indemnification — allocation of liability for third-party claims
- Limitation of Liability — caps on damages and liability exposure
- Confidentiality — scope, duration, and exceptions for confidential information
- Termination — rights, notice periods, cure periods, and post-termination obligations
- IP Assignment — ownership and assignment of intellectual property created under the agreement
- Data Protection — data processing obligations, security requirements, and breach notification
- Force Majeure — excused performance due to extraordinary events beyond control
- Governing Law — choice of law and venue selection
- Dispute Resolution — arbitration, mediation, litigation, and escalation procedures
- Non-Compete — restrictions on competitive activity post-termination
- Non-Solicitation — restrictions on soliciting employees or customers
- Warranty — representations, warranties, and disclaimers
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.

clause-library is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed 2d ago), licensed MIT. It adds 65 tokens to every session and 989 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-21.
