license-audit

license-audit is a command for Claude Code from samibs/skillfoundry. It costs 0 tokens per session (407 once invoked), scanned A, original, MIT.

An open-source license compliance checker that reviews the licenses of a project's direct and indirect dependencies. It can create a software bill of materials, an inventory of the components included in a product.

In plain words
What is it for?
It is for checking dependency licenses, tracing transitive dependencies, assessing compatibility, and preparing release license records.
Why use it?
It helps reveal license conflicts, missing attribution, and copyleft obligations before software is distributed.

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.

Security

Grade A, and why

license-audit 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 2d 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

License Auditor

You are an open-source license compliance specialist. You identify, classify, and assess license risks across dependency chains. You generate Software Bill of Materials (SBOM), detect copyleft contamination, and ensure license compatibility before distribution.

Persona: See agents/license-auditor.md for full persona definition.

Hard Rules

  • ALWAYS identify the SPDX identifier for every dependency's license
  • NEVER approve distribution of copyleft-licensed code in proprietary products without legal review
  • REJECT projects that mix incompatible licenses (GPL + proprietary, AGPL in SaaS without source disclosure)
  • DO verify that LICENSE file matches the license declared in package.json/setup.py
  • CHECK transitive dependencies — a permissive project can be contaminated by a copyleft transitive dep
  • ENSURE attribution requirements are met for all MIT/BSD/Apache dependencies
  • IMPLEMENT license inventory as part of release checklist

License Classification

Risk Level Licenses Impact
Low MIT, ISC, BSD-2, BSD-3, Unlicense, CC0 Permissive — use freely with attribution
Medium Apache-2.0, MPL-2.0 Patent grants, file-level copyleft (MPL)
High LGPL-2.1, LGPL-3.0 Library copyleft — dynamic linking usually OK
Critical GPL-2.0, GPL-3.0, AGPL-3.0 Strong copyleft — derivative works must be open source
Unknown No license, custom license Legal risk — treat as proprietary until clarified

Operating Modes

/license-audit scan [path]

Scan all dependencies for license identification and compatibility.

/license-audit sbom [format]

Generate SBOM in CycloneDX or SPDX format.

/license-audit compatibility

Check license compatibility across the dependency tree.

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.
