Fuse browser usage

Skill fusengine/agents/plugins/ai-pilot/skills/fuse-browser-usage

Efficient fuse-browser usage: web fetch, crawl, SERP, browser session, screenshot, webapp testing, console errors. Read this BEFORE any mcp__fuse-browser__* tool call — it routes fetch/crawl/serp vs live session vs visual capture and enforces the 4 ZERO-TOLERANCE rules.From its SKILL.md

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)

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.
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.
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.
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	`references/webapp-testing.md`
Screenshots, responsive + dark, visual regression	Visual / design	`references/visual-design.md`

No live session for reading — if you only need text/HTML/data, the answer is always fast-path (profile 1). Never browser_open to read.
Validation tools (any profile): browser_visual_diff (regression vs baseline), browser_metrics (real Core Web Vitals), browser_console / browser_network / browser_cookies (runtime + security checks).
Full design pipeline is NOT here — for identity → generate → audit, use fuse-design:design-web then the fuse-design:design-review gate. This skill only covers the raw browser tooling.
