An open-source license compliance checker for software dependencies and code prepared for release. It examines licenses and the obligations they may create for different ways of distributing software.

It reviews manifests, software bills of materials, individual libraries, and outbound code, then suggests whether to comply, replace, remove, or seek review.

It helps find copyleft, unknown-license, and incompatible-license risks before software ships or code is open-sourced.

Token cost

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	$0.00058	$0.04496
Opus 5	$0.00029	$0.02248
Sonnet 5	$0.00012	$0.00899
Haiku 4.5	$0.00006	$0.00450

Security

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 9d 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 — 284 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/oss-review

Runs an open source license compliance check against the practice profile in ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. Classifies dependencies by license family, maps obligations to the deployment model, flags license-unknown and non-OSI-posing-as-OSS packages, and recommends actions — comply, replace, remove, seek legal review, seek commercial license.

Instructions

Load ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. If placeholders present, stop and prompt: "Run /ip-legal:cold-start-interview first — 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 licenses 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. If the user passed a path, infer from the file; otherwise ask.
Establish the deployment model before classifying obligations — SaaS, distributed binary, internal only, or embedded. The same dependency list triggers different obligations depending on this.
Follow the workflow below. In particular:
- Read the actual license text, not just metadata — LICENSE files can be wrong, package metadata can be stale.
- Classify each package into permissive / weak copyleft / strong copyleft / public domain / non-OSI / unknown.
- Flag license-unknown as "needs review," not permissive by default.
- Flag non-OSI source-available licenses (SSPL, BUSL, Commons Clause, Elastic License, fair-source) — these are not open source.
- For outbound code, check that the chosen outbound license is compatible with every embedded dependency.
Output the memo per the template below — work-product header first, bottom line, top-of-memo flags, per-package blocks grouped by severity, jurisdiction note, outbound check (if applicable), approval routing.

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.
