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.

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.

4 Rules (ZERO TOLERANCE)

1. Fast-path FIRST (no browser launch, ~10× faster) — browser_fetch / browser_fetch_batch / browser_crawl / browser_serp_batch to read a page, bulk-fetch, crawl a site, or scrape Google SERP. Open a live session ONLY when you need interaction, JS rendering, or pixels.
2. One session, always closed — browser_open once → reuse the sessionId across browser_navigate calls → browser_close when done. Never leak sessions; the 2-min TTL is a safety net, not a substitute for closing.
3. Batch over loops — browser_serp_batch (N queries), browser_fetch_batch / browser_shots_batch (N URLs), browser_screenshot { viewports:[...], colorScheme } (responsive + dark in ONE call). Never write a per-URL loop.
4. Deterministic extraction — browser_extract_schema with containerSelector (card-by-card, correlated fields) over manual browser_snapshot parsing.

Routing — pick the profile, load the reference
