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.

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 | $0.00050 | $0.05466 |
| Opus 5.5 | $0.00020 | $0.02186 |
| Sonnet 5.5 | $0.00010 | $0.01093 |
| Haiku 4.5 | $0.00005 | $0.00547 |
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 11d 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 — 329 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
26 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.

canon is a skill published in the GitHub repository simota/agent-skills (95 stars, last pushed 3d ago), licensed MIT. It adds 50 tokens to every session and 5,466 once invoked, about $0.0002 per session on Opus 5.5. 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.
