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 | $0.00218 | $0.00218 |
| Opus 5 | $0.00109 | $0.00109 |
| Sonnet 5 | $0.00044 | $0.00044 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
hecate agent-docs.instructions.md 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
Agent Guidance Docs
Agent guidance is provider-neutral. Keep docs-ai/ as the source of truth and
use adapter files only to help a specific product discover that guidance.
Before editing this area, read:
docs-ai/core/agent-guidance.mddocs-ai/README.mddocs-ai/skills/README.md
Rules:
- Do not add tracked
.claude/or.cursor/guidance. - Keep
CLAUDE.mdas the compatibility shim importingAGENTS.md. - Keep GitHub Copilot files short; they must point to
docs-ai/rather than duplicating canonical skills or workflow rules. - When adding, moving, or deleting a skill, update
docs-ai/skills/README.md. - Run
just agent-docs-check,just docs-format-check, andjust check-linkswhen links change.
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.
