eyebrowse CLAUDE.md

eyebrowse CLAUDE.md is an instructions file for Claude Code from Evil-Bane/eyebrowse. It costs 4,175 tokens per session, scanned A, original, MIT.

Repository instructions for building EyeBrowse, a browser-control engine available as a Python library and as an MCP service. It explains the project's browser engine, supported controls, pinned versions, and important constraints.

In plain words
What is it for?
Use it when developing EyeBrowse, including its Playwright-based browser control, stealth Chromium setup, network inspection, PDFs, videos, and MCP interface.
Why use it?
It gives a coding agent the project-specific rules needed to change the code without breaking its two ways of being used or its browser behaviour.

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

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.

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.
