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 | $0.00058 | $0.03467 |
| Opus 5.5 | $0.00023 | $0.01387 |
| Sonnet 5.5 | $0.00012 | $0.00693 |
| Haiku 4.5 | $0.00006 | $0.00347 |
Grade A, and why
oss-review 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 1mo 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 — 278 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/oss-review
Runs an open source licence compliance check against the practice profile in ~/.claude/plugins/config/uk-legal-plugins/ip-legal-uk/CLAUDE.md. Classifies dependencies by licence family, maps obligations to the deployment model, flags licence-unknown and non-OSI-posing-as-OSS packages, and recommends actions — comply, replace, remove, seek legal review, seek commercial licence.
Instructions
-
Load
~/.claude/plugins/config/uk-legal-plugins/ip-legal-uk/CLAUDE.md. If placeholders present, stop and prompt: "Run/ip-legal-uk:cold-start-interviewfirst — I need to learn your practice profile (and OSS policy, if any) before I can review." If the practice profile points at an uploaded OSS policy, read that too — it is the source of truth for accepted / review / banned licences on this team. -
Establish the scope: a dependency list (package.json, requirements.txt, go.mod, Gemfile, Cargo.toml, pom.xml, SBOM), a single library, or outbound code the team is preparing to open-source.
-
Establish the deployment model before classifying obligations — SaaS, distributed binary, internal only, or embedded.
-
Follow the workflow below. In particular:
- Read the actual licence text, not just metadata.
- Classify each package into permissive / weak copyleft / strong copyleft / public domain / non-OSI / unknown.
- Flag licence-unknown as "needs review," not permissive by default.
- Flag non-OSI source-available licences (SSPL, BUSL, Commons Clause, Elastic Licence, fair-source).
- For outbound code, check that the chosen outbound licence is compatible with every embedded dependency.
-
Output the memo per the template below.
-
Respect the decision posture. When a copyleft-trigger analysis turns on a contested question, flag for attorney review. Anything classified as strong copyleft or licence-unknown goes to a solicitor/attorney before the dependency ships or the code is released.

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.

oss-review is a skill published in the GitHub repository uk-agents/uk-legal-plugins (14 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 58 tokens to every session and 3,467 once invoked, about $0.0002 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 2026-09-03.
