AC qa-browser-tester
Launch a real headless browser on the server and perform exhaustive end-to-end QA testing of a web application — clicking every button, filling every form, navigating every menu, and simulating a complete user journey. Use this skill whenever the user asks to "test the app", "check if everything works", "simulate a user", "run QA", "click through the site", or "browse the website automatically". Also trigger when the user says things like "בדוק את האתר", "תדמה משתמש", or "תבדוק שהכל עובד". Always use this skill — do not attempt browser automation without it, as it contains critical Docker-safe configuration required for Chromium to run on Linux servers.

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 contains commands that delete files, rewrite disks or execute code fetched from the network. The agent may run them without asking if it believes the instructions require it.
Replace destructive commands with safe equivalents that ask for confirmation, scope them to one folder, and stop piping curl into a shell: pin a version and a checksum.
How to improve
- 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.
