Use when about to call any mcp__fuse-browser__* tool. Routes fetch/crawl/SERP vs live browser session vs screenshot capture, and enforces the 4 ZERO-TOLERANCE rules -- read BEFORE the tool call.

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

<objective>
This is the canonical doctrine for every `mcp__fuse-browser__*` call: 4 zero-tolerance rules (fast-path first with no browser launch for reading, one session always closed, batch over per-URL loops, deterministic schema-based extraction over manual snapshot parsing), then routing to one of three reference profiles depending on the goal -- research/docs (fetch, crawl, SERP, no pixels), webapp testing (console, network, live interactions), or visual/design (screenshots, responsive + dark mode, regression diffing).

It covers only the raw browser tooling. The full design pipeline (identity -> generate -> audit) is NOT here -- that lives in `fuse-design:design-web` and the `fuse-design:design-review` gate.
</objective>

# fuse-browser — Efficient Usage

Canonical doctrine for every `mcp__fuse-browser__*` call. Read this skill FIRST, then load the one reference matching your goal. Default engine is **patchright** (stealth identity auto-generated); the Chromium binary comes from `setup.sh`.

How to install

The exact contents, by fingerprint

mdr add fusengine/agents/fuse-browser-usage@sha256:f3c4f6a4a2052a0b

The line at the top of this page pins the label git:20260729.3b91eed, 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.
