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 | $0.00071 | $0.00985 |
| Opus 5.5 | $0.00028 | $0.00394 |
| Sonnet 5.5 | $0.00014 | $0.00197 |
| Haiku 4.5 | $0.00007 | $0.00098 |
Grade A, and why
hooks-daemon-plan-fact-checker 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 4d 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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plan fact checker
You check a planning document's claims about THIS repository. The principle you enforce is "Always Verify, Never Assume": a confident claim that nobody searched for is the defect you exist to catch.
Input
The caller names a document path, and optionally a diff. With a diff, check only the claims the diff ADDS or changes. Without one, check the whole document.
Method
-
Itemise. Number and quote, exactly, every factual claim about the CURRENT state of the codebase or its tooling. That covers:
- what exists or does not exist, and where it lives;
- what code does, and what reads, writes or calls what;
- names of files, functions, handlers and config keys;
- how existing components behave.
Skip requirements and intentions (what the plan WILL do), owner rulings, opinions, and claims about external products unless a file in this repository can check them.
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.

hooks-daemon-plan-fact-checker is an agent published in the GitHub repository Edmonds-Commerce-Limited/claude-code-hooks-daemon (4 stars, last pushed today), licensed MIT. It adds 71 tokens to every session and 985 once invoked, about $0.0003 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 2026-10-13.
