Browse reusable Agent Skills, each with a clear purpose and practical guidance.
MANDATORY: Activate this skill ANY TIME you need to build the project, run tests, or verify code health in Puppeteer. You MUST use this skill before executing commands like npm test, npm run build, or linters, as it contains critical, repository-specific instructions on how to correctly format these commands, filter test runs, and interpret failures.
Measure Storybook startup time from spawning `storybook dev` until the first story renders in the browser. Use when the user asks about Storybook boot time, server-ready timing, first story render timing, startup regressions, benchmarking with repeat runs, or comparing Storybook versions or feature flags.
Analyse a branch or PR and automatically capture before/after screenshots of every UI surface its changes touch, then pixel-diff the pairs to surface what actually changed and assemble PR-ready before/after montage images. Generic and diff-driven: it derives the capture targets from the diff (changed tools/routes → URLs) instead of hand-listing screens, captures "before" from the base branch and "after" from the head, then keeps only the views that visually differ. Each comparison is auto-cropped to the region that actually changed (the bounding box of differing pixels), falling back to the full page only when the change spans most of it. Use for before/after shots, a visual diff of a branch/PR, "screenshots for the PR description", "show what changed in the UI", or a side-by-side of UI changes. Takes a PR number/URL (resolved via gh) or a branch; defaults to the current branch vs its base. Flags: --scope <selector>, --base <ref|merge-base>, --theme light|dark|both, --all (capture every route, not just changed), --no-autocrop, --pagewide <n>, --threshold <n>.
Full UI investigation of the current branch's feature. Enumerates every view and state (empty, populated, loading, error, each dialog/menu/panel, responsive breakpoints, light + dark + RTL), captures them with the stubbed Playwright harness, assembles a single-image HTML walkthrough with a global light/dark toggle slider, then runs two review passes: visual/consistency (alignment, spacing, professionalism, dark/light parity, contrast, truncation) and UX/ease-of-use (flow, discoverability, affordances, empty/error states, expectations). Use when asked for a UI walkthrough, screenshot review, design or QA pass, "find anywhere to make it easier/better for users", or before merging frontend work. Pass --fix to auto-apply safe frontend fixes and re-capture; --theme to limit themes; --no-rtl to skip RTL.
Agentic end-to-end testing for any project: backend verification via the project CLI, frontend verification via agent-browser (web), and desktop verification via CDP (Electron). Drives the real surface, captures visually confirmed evidence, and publishes a structured report to the LobeHub verify platform. Triggers on 'cli test', 'test with cli', 'verify with cli', 'backend test with cli', 'local test', 'test in electron', 'test desktop', 'manual test', 'test report', or any local end-to-end verification task.
Triage Coverity Scan defects (https://scan.coverity.com) for this project — fetch defect lists, fetch per-defect details, and apply triage decisions (Bug / FalsePositive / Intentional with severity, action, and a comment). Use when the user asks to "review Coverity defects", "triage Coverity findings", "fetch Coverity outstanding", or anything mentioning Coverity Scan, CIDs, or scan.coverity.com.
Use when you need to analyze git diffs or pull requests to understand what changed, affected components, and risks
Run one Terminal-Bench task through a bounded Paperclip smoke/diagnosis/fix loop. Use when asked to drive Terminal-Bench until it passes, rerun a Terminal-Bench loop, or iterate with board-gated fixes and diagnosis.
Discover recently referenced Paperclip pull requests, mechanically verify their current-head readiness, drive non-draft PRs back to green through their originating issues, and publish a merge-confidence report without merging.
Iterate on a GitHub PR until latest-head checks are green or a precise blocker is named. Use when a PR still has failing or pending checks after review fixes, including after greploop.
