drive-local-webapp
Launch or connect to a local development web server and drive it with a reusable headless-Chromium command interface. Use when asked to render, smoke-test, interact with, verify, or screenshot a local frontend or HTML mockup.
Overview
Launch or connect to a local development web server and drive it with a reusable headless-Chromium command interface. Use when asked to render, smoke-test, interact with, verify, or screenshot a local frontend or HTML mockup.
Read full documentation
Source documentation, not instructions for this website. Review permissions before running any commands.
Drive a local web app
Use the bundled Playwright driver instead of writing a one-off browser script.
It keeps one page alive while reading commands from standard input and reports
each command as OK or FAIL.
One-time setup
Resolve this installed skill's directory, then run:
cd <drive-local-webapp-skill-directory>
npm ci
npx playwright install chromium
Node.js 20 or newer is recommended. Browser binaries are cached by Playwright. Verify the installation reproducibly:
npm run self-check
Workflow
-
Start the target application's normal development or demo server. Use throwaway fixtures, never production or personal data. Check that the chosen port is free before binding it.
-
Run
node scripts/driver.mjsfrom this skill directory and pipe one command per line:DRIVER_SCREENSHOT_DIR=/tmp/webapp-shots node scripts/driver.mjs <<'EOF' nav http://127.0.0.1:8766/ wait-for text=Dashboard click button:text-is("Settings") fill input[placeholder="API token"] :: demo-token click button:text-is("Save") screenshot console --errors EOF -
Treat any
FAILline or non-zero exit as a failed check. Treat a non-emptyCONSOLE_ERRORSarray as a failed check unless the error is explicitly expected. -
Inspect the screenshot itself. File existence does not prove the intended UI rendered.
If the host sandbox blocks Chromium process creation, rerun the same driver command with the client's narrowly scoped approval mechanism. Do not reinstall Chromium or alter the application to work around a host permission error.
Only navigate to a local page you trust or a URL the user explicitly placed in scope. Headless Chromium is not a security boundary: page JavaScript can make network requests and exercise the permissions available to the browser process. Do not use this driver as a general-purpose browser for untrusted sites.
Commands
nav <url>
wait-for <selector>
click <selector>
fill <selector> :: <value>
set <selector> :: <value>
press <key>
wait <milliseconds>
eval <javascript-expression>
screenshot [absolute-path]
console --errors
Use :text-is("Label") for exact text. Playwright's :has-text() is
case-insensitive substring matching and can silently click the wrong control.
Keep screenshots outside the target repository. The driver defaults to the
system temporary directory, or use DRIVER_SCREENSHOT_DIR. It refuses to
overwrite an existing screenshot path.
Common failures
- Selectors containing spaces require the literal
::separator forfillandset. - Hidden tab content may exist in the DOM; click the actual tab before waiting on its contents.
- Charts initialized inside
display:nonecontainers may have zero width. Activate the tab, wait, and verify the app resizes or lazily initializes the chart. - A client-side token gate may leave the screen loading without a console error. Inspect the application's setup UI and use a demo token.

# Drive a local web app
Use the bundled Playwright driver instead of writing a one-off browser script.
It keeps one page alive while reading commands from standard input and reports
each command as `OK` or `FAIL`.
## One-time setup
Resolve this installed skill's directory, then run:
```sh
cd <drive-local-webapp-skill-directory>
npm ci
npx playwright install chromium
```
Node.js 20 or newer is recommended. Browser binaries are cached by Playwright.
Verify the installation reproducibly:
```sh
npm run self-check
```
## Workflow
1. Start the target application's normal development or demo server. Use
throwaway fixtures, never production or personal data. Check that the chosen
port is free before binding it.
2. Run `node scripts/driver.mjs` from this skill directory and pipe one command
per line:
```sh
DRIVER_SCREENSHOT_DIR=/tmp/webapp-shots node scripts/driver.mjs <<'EOF'
nav http://127.0.0.1:8766/
wait-for text=Dashboard
click button:text-is("Settings")
fill input[placeholder="API token"] :: demo-token
click button:text-is("Save")
screenshot
console --errors
EOF
```
3. Treat any `FAIL` line or non-zero exit as a failed check. Treat a non-empty
`CONSOLE_ERRORS` array as a failed check unless the error is explicitly
expected.
4. Inspect the screenshot itself. File existence does not prove the intended UI
rendered.
If the host sandbox blocks Chromium process creation, rerun the same driver
command with the client's narrowly scoped approval mechanism. Do not reinstall
Chromium or alter the application to work around a host permission error.
Only navigate to a local page you trust or a URL the user explicitly placed in
scope. Headless Chromium is not a security boundary: page JavaScript can make
network requests and exercise the permissions available to the browser process.
Do not use this driver as a general-purpose browser for untrusted sites.
## Commands
```text
nav <url>
wait-for <selector>
click <selector>
fill <selector> :: <value>
set <selector> :: <value>
press <key>
wait <milliseconds>
eval <javascript-expression>
screenshot [absolute-path]
console --errors
```
Use `:text-is("Label")` for exact text. Playwright's `:has-text()` is
case-insensitive substring matching and can silently click the wrong control.
Keep screenshots outside the target repository. The driver defaults to the
system temporary directory, or use `DRIVER_SCREENSHOT_DIR`. It refuses to
overwrite an existing screenshot path.
## Common failures
- Selectors containing spaces require the literal ` :: ` separator for
`fill` and `set`.
- Hidden tab content may exist in the DOM; click the actual tab before waiting
on its contents.
- Charts initialized inside `display:none` containers may have zero width.
Activate the tab, wait, and verify the app resizes or lazily initializes the
chart.
- A client-side token gate may leave the screen loading without a console
error. Inspect the application's setup UI and use a demo token.

Skill source recorded
Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.
Review before install: Avoid automatic install
License: NOASSERTION
- Permission surface may require sandboxing
- Repository license is NOASSERTION; no explicit license file or declaration in package.json, making reuse terms unclear.
- The driver's eval command can execute arbitrary JavaScript in the page context; while the skill warns against untrusted sites, this remains a potential risk if misused.
- Low GitHub adoption signal
- Quality score needs review
- Permission surface needs review: secrets or environment access, shell or command execution
- GitHub adoption: 18 GitHub stars
- Stars/forks activity: 18 stars, 5 forks; issue activity unavailable in current metadata
- Permission surface: secrets or environment access, shell or command execution
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Start with one small task
- 1Read the source. Confirm the input, expected output, dependencies and permissions.
- 2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
- 3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Source & usage notes
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.

Agent access
This page exposes the same decision, trust, audit, use-case, and install signals through the Registry API, so agents can rank this skill without scraping the UI.
