AB screencast-studio
Auto-record narrated demo videos of any web UI from a Playwright-driven walkthrough — primary use case is the vibe-coding test loop (you just shipped a feature with AI help and need to verify it / vibe-show it / iterate on it without manual screen recording). Output is a final.mp4 (synthetic cursor lerp + Material click ripples + burned-in subtitles + optional persistent mask regions for sensitive UI) plus a 4-pass review screenshot set for visual + privacy QA. Activate when the user wants to test or share something they just vibe-coded, or asks for a polished walkthrough / OSS feature demo / bug repro screencast / tutorial recording.
As a process B 66/100 · Nearly there — weak spots: result and completion, running it twice
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.

Process rating: all ten parameters 66/100
- 0Result and completion. Does not say what the result is
- 30Running it twice. 6 mutating operations with no state check
- 60Tools and files. Uses tools (node) that frontmatter does not declare
- 70When it triggers. States when to use, but not when not to
- 70Inputs and preconditions. Inputs and preconditions are listed
- 70Failures and branches. 6 branches

- 100Progress reporting. Reports progress
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.
