agent-browser
Agent-browser usage guide. Read this before running any agent-browser commands. Covers the snapshot-and-ref workflow, navigating pages, interacting with elements (click, fill, type, select), extracting text and data, taking screenshots, managing tabs, handling forms and auth, waiting for content, running multiple browser sessions in parallel, and troubleshooting common failures. Use when the user asks to interact with a website, fill a form, click something, extract data, take a screenshot, log into a site, test a web app, or automate any browser task.
derive-client
Reverse-engineer a website's internal API by recording browser traffic into a HAR file, then generate a standalone client or CLI that calls the endpoints directly, with no browser needed after the first recording. Use when asked to “derive a client”, “build a CLI for <site>”, “reverse engineer this site's API”, “record network requests”, “turn this site into an API”, or when the same site will be automated repeatedly and direct HTTP calls would beat driving the browser every time.
dogfood
Systematically explore and test a web application to find bugs, UX issues, and other problems. Use when asked to “dogfood”, “QA”, “exploratory test”, “find issues”, “bug hunt”, “test this app/site/platform”, or review the quality of a web application. Produces a structured report with full reproduction evidence -- step-by-step screenshots, repro videos, and detailed repro steps for every issue -- so findings can be handed directly to the responsible teams.
electron
Automate Electron desktop apps (VS Code, Slack, Discord, Figma, Notion, Spotify, etc.) using agent-browser via Chrome DevTools Protocol. Use when the user needs to interact with an Electron app, automate a desktop app, connect to a running app, control a native app, or test an Electron application. Triggers include “automate Slack app”, “control VS Code”, “interact with Discord app”, “test this Electron app”, “connect to desktop app”, or any task requiring automation of a native Electron application.
ui-regression
This skill should be used when the user asks to “verify UI changes”, “test every screen and action”, “run regression QA”, “check a deployed UI”, or “validate an extension release”. Test known web and browser-extension workflows on localhost, staging, or production with action coverage, recovery, localization, accessibility, and real integration evidence. Use dogfood for open-ended bug discovery.
webmcp-gen
Build and validate experimental WebMCP tools for an existing web page. Use when an agent needs to expose a site's real workflows as page tools, create webmcp.init.js, define deterministic checks, or compare WebMCP with accessibility-tree automation.
