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 | $0.04175 | $0.04175 |
| Opus 5 | $0.02087 | $0.02087 |
| Sonnet 5 | $0.00835 | $0.00835 |
| Haiku 4.5 | $0.00417 | $0.00417 |
Grade A, and why
eyebrowse CLAUDE.md 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 — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — EyeBrowse build notes
Guidance for working in this repo. EyeBrowse is a stealthy, LLM-drivable
browser-control engine consumed two ways from one codebase: as a Python
library (from eyebrowse import EyeBrowse) and over MCP (FastMCP, stdio). The engine
holds no workflow logic — consumers decide what to do; it provides what's possible.
Engine: CloakBrowser (stealth Chromium, Chrome/146). A Playwright drop-in —
launch_async() / launch_persistent_context_async() return a standard Playwright
Browser / BrowserContext. Everything above the launch primitive runs on the plain
Playwright page, so engine/engine.py is the ONLY engine-specific layer. Chromium gives us
the full CDP surface (trusted cursorless clicks, Network/initiator inspection, MHTML,
PDF, native video), exposed as thin tools. CloakBrowser's stealth is its patched binary + an
auto --fingerprint={seed} / --fingerprint-platform (nothing for us to spoof); we map only
its native knobs — humanize, geoip, locale, timezone, proxy. HAR is
Playwright-native (record_har_path), video is Playwright-native (record_video_dir) — no
custom recorders. (EyeBrowse was originally built on Camoufox/Firefox; that engine has been
removed — see git history if you need the old launch path.)

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.

eyebrowse CLAUDE.md is an instructions file published in the GitHub repository Evil-Bane/eyebrowse (1 stars, last pushed 2mo ago), licensed MIT. It adds 4,175 tokens to every session, about $0.0209 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.
