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 | $0.00051 | $0.02091 |
| Opus 5 | $0.00026 | $0.01045 |
| Sonnet 5 | $0.00010 | $0.00418 |
| Haiku 4.5 | $0.00005 | $0.00209 |
Grade A, and why
agent-browser 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 9d 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.

The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Overview
Live browser verification using agent-browser — a fast Rust CLI wrapping Playwright. Drives a real Chromium instance through shell commands — no test files, no framework setup, no CI configuration required.
Use for:
- Verifying a running app against acceptance criteria
- Checking critical user flows after a feature is built
- Taking screenshots for visual review
- Debugging UI issues that only appear in a real browser
- Form and interaction testing during development

Install globally once:
npm install -g agent-browser
agent-browser install # downloads Chromium

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.
