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 | $0.01237 |
| Opus 5.5 | $0.00026 | $0.00495 |
| Sonnet 5.5 | $0.00013 | $0.00247 |
| Haiku 4.5 | $0.00006 | $0.00124 |
Grade A, and why
open-source-policy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Open-Source Policy
Create an open-source usage and contribution policy for "$ARGUMENTS". Generate a comprehensive policy governing how the organization consumes and contributes to open-source software.
Note: AI-generated legal content does not constitute legal advice. Consult a qualified attorney.
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
Check that .metapowers/legal/<project>/00-assess.md exists. If it does not exist, stop and tell the user:
"Run an Assess skill first (e.g.
/legal:risk-assessment <project>) to generate the prerequisite assessment artifact."

Draft approved license categories with examples:
- Permissive licenses (generally approved):
- MIT License — minimal restrictions, compatible with proprietary use
- Apache License 2.0 — includes patent grant, notice requirements
- BSD 2-Clause / 3-Clause — minimal restrictions, attribution required
- ISC License — functionally equivalent to MIT
- Weak copyleft licenses (conditional approval — requires review):
- LGPL 2.1 / 3.0 — copyleft applies to modifications of the library itself, not linking code; dynamic linking generally safe, static linking requires care
- MPL 2.0 — file-level copyleft, modifications to MPL files must be shared, proprietary files can coexist
- EPL 2.0 — module-level copyleft, similar to MPL but with patent provisions
- Strong copyleft licenses (restricted — requires legal approval):
- GPL 2.0 / 3.0 — copyleft extends to derivative works, use in proprietary products requires careful analysis
- AGPL 3.0 — network use triggers copyleft, highest restriction for SaaS products
- SSPL — controversial license, not OSI-approved, treated as restricted
- Prohibited licenses:
- Licenses with field-of-use restrictions incompatible with business purpose
- Custom or unclear licenses without legal review
- Licenses with viral patent retaliation clauses conflicting with company patent portfolio
- Permissive licenses (generally approved):
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.
- 3d ago First seen · 94 lines · 65 tokens per session scan A 25f19fbfdc05
open-source-policy 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 1,237 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.
