BF browser-driver
Attach to the user's OWN already-logged-in system browser over the Chrome DevTools Protocol (CDP) with Playwright, so automation reuses their existing session and avoids re-logging-in with 2FA. Use this ONLY when a fresh/headless browser won't do because the task needs the user's live login — e.g. 'do this in my browser', 'use my existing session/login', 'I'm already signed in, don't make me log in again', driving a console/dashboard behind 2FA while they watch. Do NOT use for ordinary browsing, scraping public pages, headless tests, or any automation that doesn't need their real session — use the agent's built-in browser tool / Playwright or chrome-devtools MCP / computer-use for those. Covers launching Chrome/Edge/Brave with a remote-debugging port, per-step one-shot Playwright scripts, screenshot-audited steps, shadow-DOM/overlay handling, handing control back at Touch ID/security-key/QR walls, one-time-secret capture, and cleanup. Own browser, own accounts, never to bypass auth.

What is at stake
Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
The skill asks for more than the task needs: broad tool access, credential environment variables, binaries. Every extra permission widens the damage from a mistake or a compromise.
Narrow allowed-tools and the variable list to the minimum; replace binaries with readable sources or scripts.
How to improve
- For Hermes the description must be one sentence under 60 characters; move the conditions to a "When to Use" section.
- The text references files that are not there: add them or drop the references.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
