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.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00161 | $0.00389 |
| Opus 5 | $0.00081 | $0.00195 |
| Sonnet 5 | $0.00032 | $0.00078 |
| Haiku 4.5 | $0.00016 | $0.00039 |
Grade A, and why
brooks-test 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 10d 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
Brooks-Lint — Test Quality Review
Setup
Read in order:
../_shared/common.md— Iron Law, Project Config, Report Template, Health Score../_shared/source-coverage.md— book coverage, exceptions, tradeoffs../_shared/test-decay-risks.md— test-space symptom definitions and sourcestest-guide.md(this directory) — the test quality review framework
Process
Scope: if the user did not share test files or point to a test directory, apply Auto
Scope Detection (../_shared/common.md) first.
- Build the test suite map (guide's "Before You Start" section)
- Scan for each test decay risk in the order specified (Steps 1–4 of the guide)
- Apply the Iron Law and output using the Report Template (Step 5 of the guide)
Mode line in report: Test Quality Review
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

brooks-test is a skill published in the GitHub repository hyhmrright/brooks-lint (1,462 stars, last pushed 2d ago), licensed MIT. It adds 161 tokens to every session and 389 once invoked, about $0.0008 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 2026-08-30.
