web-debug from sentimony/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

You MUST use this when interacting with or testing local web applications with Playwright - verifying frontend functionality, debugging UI behavior, capturing browser screenshots, or viewing browser console logs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Web Debug
To test local web applications, write native Python Playwright scripts.
**Helper Scripts Available**:
- `scripts/with_server.py` - Manages server lifecycle (supports multiple servers)
## Boundary with `debugging`
Use `debugging` for root-cause methodology: symptom, evidence, hypothesis, causal
explanation, and fix. Use `web-debug` when browser interaction or browser/runtime evidence
is needed. They compose: `debugging` asks the question, `web-debug` returns DOM, console,
network, navigation, screenshot, or runtime evidence, and `debugging` updates the hypothesis.
If static inspection or tests can localize the issue, browser capability is unnecessary.
**Always run scripts with `--help` first** to see usage. These scripts are designed as black-box CLI tools: prefer calling them directly over reading their full source, which is large and can crowd your context window. Reading the source to audit or customize behavior is expected and encouraged whenever you need it.
## Decision Tree: Choosing Your Approach
```
User task → Is it static HTML?
├─ Yes → Read HTML file directly to identify selectors
│ ├─ Success → Write Playwright script using selectors

How to install
mdr add sentimony/skills/web-debug@sha256:40087f269c23dab4The line at the top of this page pins the label v0.0.16, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
