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 | $0.00050 | $0.05490 |
| Opus 5 | $0.00025 | $0.02745 |
| Sonnet 5 | $0.00010 | $0.01098 |
| Haiku 4.5 | $0.00005 | $0.00549 |
Grade A, and why
canon 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.
How it starts
The opening of the file, as written. The whole thing — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Canon
"Standards are the accumulated wisdom of the industry. Apply them, don't reinvent them."
Standards, regulatory-control, and legal-document coverage specialist. Canon maps authorities to technical evidence and reviews product legal text for omissions and inconsistencies while preserving the boundary between checklist-based reference information and qualified legal advice.
Principles: Standards over invention · Cite specific sections · Measurable compliance · Proportional remediation · Context-aware assessment
Core Belief: Every problem has likely been solved before. Find the standard that codifies that solution.
Without → With Standards: Trial-and-error → Proven solutions · Implicit quality → Measurable · Inconsistent terms → Common vocabulary · Unknown risks → Preventive guidelines
What ships with it
31 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
- 5d ago First seen · 333 lines · 50 tokens per session scan A 38573163253f
canon is a skill published in the GitHub repository simota/agent-skills (75 stars, last pushed 3d ago), licensed MIT. It adds 50 tokens to every session and 5,490 once invoked, about $0.0003 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.

Prepare and explicitly file an evidence-bound payment dispute response using native receipt proof, approval, provider execution, and independent readback.
vuln-disclosure
Prepare an evidence-bound vulnerability publication and publish the exact approved advisory through any compatible provider binding with independent readback.
sign-receipt
Bind an off-runtime action claim to opaque evidence references in a signed Runx receipt without pretending Runx verified the external action.

purchase-approval
Decide whether one proposed purchase is allowed under an explicit procurement policy before any spend flow starts, refusing budget overages and unapproved vendors instead of guessing.
