Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Signup walkthrough procedure
The browser is the only source of truth. A step you did not perform in the browser did not
happen; a result you did not see is unknown. Write only the artifact path declared by Tin.
## 1. Drive the browser with the `camoufox` tools
1. Tin mounted the `camoufox` MCP server. It runs one persistent Camoufox, a
fingerprint-hardened Firefox that Cloudflare's human-verification checks accept, through
the Tin-managed WARP proxy. It is the only browser. Never write helper scripts, never
launch a browser yourself, and never create any file other than the declared report.
2. The tools act on one page whose cookies, login state, and current URL survive between
calls:
- `camoufox.navigate(url)` opens a URL and returns its URL, title, and text.
- `camoufox.current_page()` returns the URL and title without touching the page.
- `camoufox.page_text(max_chars)` and `camoufox.snapshot(max_chars)` read the visible
text and the accessibility tree.
- `camoufox.click(selector)`, `camoufox.click_role(role, name)`,
`camoufox.fill(selector, value)`, and `camoufox.press(key)` act like a user.

How to install
mdr add tin-computer/tin/signup-walkthrough@sha256:015964798aa5c4c0The line at the top of this page pins the label git:20261012.7331d61, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
