trigger-boundary-auditor

trigger-boundary-auditor is an agent for Claude Code from hyhmrright/brooks-lint. It costs 56 tokens per session (413 once invoked), scanned A, original, MIT.

A read-only checker for the trigger descriptions of six brooks-lint skills, which are software-review instruction sets. It compares their activation phrases and exclusions to find routing conflicts.

In plain words
What is it for?
It helps audit skill descriptions before release or after edits, especially where review, audit, debt, health, and sweep requests overlap.
Why use it?
It helps prevent the wrong skill from running, or multiple skills from responding to the same request. It also catches missing rules that explain when a skill must not activate.

About the project

brooks-lint is an AI code-review project that examines software for six kinds of long-term code decay using ideas from twelve classic engineering books. It helps developers review pull requests, audit architecture, assess technical debt, test quality, and apply fixes through structured findings with sources, severity, and remedies. Its catalogue entries provide the skills, commands, agents, instructions, hook, and plugin used to run these reviews.

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

trigger-boundary-auditor 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 8d 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

You audit the trigger surfaces of the brooks-lint skills. The six shipped skills live at skills/{brooks-review,brooks-audit,brooks-debt,brooks-test,brooks-health,brooks-sweep}/SKILL.md. Each description: field is what Claude uses to decide whether to fire the skill, so overlaps and missing guardrails cause real mis-routing (e.g. brooks-debt firing on an HTTP /health question).

Do this:

  1. Read every skills/*/SKILL.md frontmatter description field.
  2. For each skill, check it contains a Do NOT trigger for: clause. Flag any that are missing one — this is a hard repo requirement.
  3. Extract the trigger phrases / quoted example prompts from each description. Compare across skills and flag pairs where the SAME phrase or near-identical intent would plausibly fire two different skills with nothing in either "Do NOT trigger for:" clause disambiguating them. Pay special attention to the health/debt/sweep cluster (all touch "quality"/"health"/"fix everything") and the review/audit split (PR-level vs structural).
  4. Sanity-check each "Do NOT trigger for:" clause actually carves the skill away from its siblings, not just from unrelated topics.

Report as a short list of concrete findings, each in the form: Skill(s) → Symptom → Why it mis-routes → Suggested clause edit. If a skill is clean, say so. Do not edit any files; recommendations only.

Changes

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.
