electron-playwright-validator SKILL.md skillA
electron-playwright-validator from johnkozaris/jko-claude-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

This skill should be used when a user asks to launch, inspect, automate, test, validate, or debug an Electron desktop UI through Playwright/CDP, including blank renderers, runtime import failures, accessibility snapshots, layout defects, click-through flows, or post-change checks. Not for native macOS or mobile apps, browser-only pages, or unit-level IPC tests. The target project must provide Electron and Playwright.
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
# Electron Playwright Validator
Use the bundled `e-cli` as the interface. It keeps one Electron process alive
and connects subsequent commands through CDP, avoiding repeated startup cost.
## Resolve the bundled tool
The executable is `scripts/e-cli` relative to this skill directory. Resolve that
path from the host's skill context. In a full plugin install the equivalent path
is:
```bash
E_CLI="${CLAUDE_PLUGIN_ROOT}/skills/electron-playwright-validator/scripts/e-cli"
```
Verify `"$E_CLI" --help`, then run from the project root. The tool resolves
Electron and Playwright from the project's dependencies; do not install global
copies or silently change the project's toolchain.
Direct skill installs can resolve `scripts/e-cli` from the skill directory. Use
`node "$E_CLI"` when a distribution loses executable mode.
## Drive one observable transaction at a time
1. Launch the app.
2. Read an accessibility snapshot.
3. Resolve one target from current state.
4. Act.
5. Wait for a product postcondition, then snapshot again.
6. Capture pixels only when they can reveal a rendering or layout defect.
7. Close the session when validation finishes.

How to install
mdr add johnkozaris/jko-claude-plugins/electron-playwright-validator@sha256:d809e6f7545da3d5The line at the top of this page pins the label git:20260725.6c1b23d, 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.
