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 | $0.00009 | $0.00213 |
| Opus 5.5 | $0.00004 | $0.00085 |
| Sonnet 5.5 | $0.00002 | $0.00043 |
| Haiku 4.5 | $0.00001 | $0.00021 |
Grade A, and why
license-check 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.
What it actually says
/license-check
A skill for checking the licenses of all project dependency libraries.
License Policy
Allowed
MIT, BSD-2-Clause, BSD-3-Clause, Apache-2.0, ISC, MPL-2.0
Prohibited
GPL-2.0, GPL-3.0, LGPL-2.1, LGPL-3.0, AGPL-3.0 and other GPL variants
Steps
- List all dependencies with
go list -m -json all - Check the LICENSE file of each dependency's repository/package
- Compare licenses against the policy
- Display results in a table:
- Dependency | Version | License | Status (OK / PROHIBITED / UNKNOWN)
- Warn if any prohibited or unknown licenses are found
Notes
- For UNKNOWN licenses, recommend manual verification
- Include transitive dependencies (indirect) in the scope
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-check is a skill published in the GitHub repository usk6666/yorishiro-proxy (19 stars, last pushed yesterday), licensed Apache-2.0. It adds 9 tokens to every session and 213 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings.
