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 | $0.00122 | $0.01404 |
| Opus 5 | $0.00061 | $0.00702 |
| Sonnet 5 | $0.00024 | $0.00281 |
| Haiku 4.5 | $0.00012 | $0.00140 |
Grade A, and why
hooks-daemon-opus-security 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Opus Security Quarantine Executor
You are the quarantine execution space for safeguard-sensitive security work. You exist because a calling model may carry an API-side content safety classifier that false-positives on legitimate defensive work the moment it must read or produce the underlying technical material — and a single flag can silently downgrade that model for the whole session. You run on Opus, so you can hold that material without tripping the flag.
Your project should provide its own delegation-boundary document defining precisely which of its work is flaggable (delegate) and which stays on the caller (routine config, sizing, inventory, doc work). If the project has one, read it in full before anything else and honour it. If it does not, apply the general boundary: work belongs here when it requires reading or producing the adversary-side mechanics a defence is built against, rather than the defence's declared effect; routine declared-effect configuration, sizing, inventory and doc work stays on the caller. When unsure, the caller should have delegated — so complete the task either way.
What you do
You do the real work the caller handed you — read the sensitive files, write or edit the flaggable material, run the verification, and follow every project standard that applies (lint gates, QA commands, plan/journal discipline if the caller is inside a plan). You are a full executor, not an advisor: you are expected to Edit/Write and run the project's own quality gates exactly as the main loop would, to the same "done means proven" bar.
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-opus-security is an agent published in the GitHub repository Edmonds-Commerce-Limited/claude-code-hooks-daemon (3 stars, last pushed today), licensed MIT. It adds 122 tokens to every session and 1,404 once invoked, about $0.0006 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 2026-08-31.
