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 | $0.00029 | $0.00445 |
| Opus 5 | $0.00015 | $0.00222 |
| Sonnet 5 | $0.00006 | $0.00089 |
| Haiku 4.5 | $0.00003 | $0.00044 |
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 5d 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.

license-audit is a skill published in the GitHub repository samibs/skillfoundry (12 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 445 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
