Browser automation toolkit using Selenium WebDriver 4+ with Java 21+ and JUnit 5. Use when asked to create, debug, or run Selenium tests, implement Page Object Model, handle explicit waits with WebDriverWait, capture screenshots, verify UI elements with AssertJ assertions, test forms, validate user flows, or set up Maven test projects. Supports Chrome, Firefox, and Edge browsers.
Invisible Chrome automation for web scraping via CDP. Use when WebFetch fails or gets blocked (403, 429, Cloudflare, bot protection, JS-rendered pages). Launches your real Chrome install completely hidden, sends commands via Chrome DevTools Protocol. Sites see a normal browser with real extensions - no detectable automation. Learns which domains block and skips straight to stealth on future requests. Also handles form filling, clicking, screenshots, and scraping dynamic content.
Programmatic canvas toolkit for creating, editing, and refining Excalidraw diagrams via MCP tools with real-time canvas sync. Use when an agent needs to (1) draw or lay out diagrams on a live canvas, (2) iteratively refine diagrams using describe_scene and get_canvas_screenshot to see its own work, (3) export/import .excalidraw files or PNG/SVG images, (4) save/restore canvas snapshots, (5) convert Mermaid to Excalidraw, or (6) perform element-level CRUD, alignment, distribution, grouping, duplication, and locking. Requires a running canvas server (EXPRESS_SERVER_URL, default http://localhost:3000).
Use SweetLink to connect your AI agent to a real browser tab. Like Playwright, but works in your current tab. Enables authentication, screenshots, smoke tests, and DevTools telemetry without headless automation.
Audit a newsletter draft for visual opportunities, score and rank them, and generate on-brand visual assets using AI. Use when enhancing a newsletter draft with visuals, when a draft has [screenshot] placeholders, when asked to 'add visuals to the newsletter', 'create images for this issue', 'make this more visual', or when any newsletter draft needs strategic visual enhancement.
Create polished frontend interfaces from designs/screenshots with high design quality. Use for web components, pages, replicating UI designs, extracting design guidelines, avoiding AI slop aesthetics.
Post-deploy canary monitoring. Watches the live app for console errors, performance regressions, and page failures using the browse daemon. Takes periodic screenshots, compares against pre-deploy baselines, and alerts on anomalies. Use when: "monitor deploy", "canary", "post-deploy check", "watch production", "verify deploy".
Exhaustively extract UX patterns from a reference web app. Walks every screen, captures screenshots of every state, records interaction patterns, copy verbatim, keyboard shortcuts, responsive treatments, motion, and empty/error/loading states. Produces a reusable pattern library that other audits can compare against. The inverse of ux-audit — asks 'what is the bar?' rather than 'does this match the bar?'. Trigger with 'learn from X', 'extract patterns from X', 'study X's UX', 'reverse engineer the UX of X', 'build a pattern library from X'.
Upload screenshots and images to GitHub, returning markdown-ready URLs for PRs, issues, and comments. Use when needing to attach images to GitHub PRs/issues, upload screenshots, embed visuals in markdown, or when a workflow produces images that should be shared on GitHub. Trigger words - upload image, attach screenshot, add image to PR, embed screenshot, visual diff, before/after screenshot.
Turn an existing HTML page, landing page, oral script, memo draft, result table, or structured source material into a Xiaohongshu card-style image note. Use this when the user wants page-by-page card planning, cover copy, card text, or a design-ready Xiaohongshu图文 brief based on source material rather than writing a plain note from scratch. This skill is especially for 3:4 Xiaohongshu cards that may mix image-led pages with high-density memo pages, using strong information hierarchy and screenshot-worthy text density rather than generic sparse carousel copy.
Autonomously test an app UI (iOS or Android) by running interact-screenshot-verify loops using argent MCP tools. Use when testing a UI flow, verifying login works, testing navigation, or running an end-to-end UI test scenario.
Route agents to the right web access method only when built-in web access tools are unavailable or insufficient for the task. Use for public search/fetch, browser interaction, authenticated browsing, screenshots, web app testing, or Electron app control when built-in tools cannot handle the requirement.
