One of 15 test cases the skill fixed. Same model, same prompt, with and without the skill.
We have a `findings.json` file generated from a web test run. What command should we execute to score our QA findings, enforcing a pass threshold of 85, comparing against `.qa-baselines/latest.json`, updating the baseline file, and producing JSON output?
| Checked | Without skill | With skill |
|---|---|---|
| Executes python scripts/qa_health_scorer.py findings.json | Missed | Passed |
| Includes --threshold 85 in the command | Passed | Passed |
| Includes --save-baseline in the command | Missed | Passed |
The instructions your model reads when the skill loads.
The agent drives Chrome MCP for live browser testing and uses four Python tools for deterministic health scoring, accessibility auditing, visual regression tracking, and report generation.
Before the QA sweep, confirm these inputs. If any is unknown or vague, ASK — do not assume:
Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
