hooks-daemon-opus-security

hooks-daemon-opus-security is an agent for coding agents from Edmonds-Commerce-Limited/claude-code-hooks-daemon. It costs 122 tokens per session (1,404 once invoked), scanned A, original, MIT.

A separate security-focused execution agent for defensive work involving safeguard-sensitive technical material. It is intended to handle the complete delegated task in an isolated context.

In plain words
What is it for?
Use it for defensive security tasks that require examining or producing the technical details of the threat being defended against.
Why use it?
It keeps potentially misclassified security material separate from the calling agent’s session while supporting legitimate defensive analysis.

Token cost

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.

Security

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.
