fuse-browser-usage

# 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 | Goal | Profile | Reference | |------|---------|-----------| | Read docs, bulk-fetch, crawl, scrape SERP (no pixels) | Research / docs | `references/research-docs.md` | | Test a running webapp (console, network, interactions) | Webapp testing | `refe...
