// Run e2e tests relevant to the current changes. Selects `.feature` files based on `git diff`, runs `just test-quick`, and skips e2e when changes are server-only with no UI impact. Triggers on "run tests", "test this", "check if it works", "e2e", "test the changes".
Capture production-like PR evidence (screenshots and video) by running the app on an ephemeral pu box and driving headless Chrome with Playwright — entirely off the user's machine, the way CI builds. Use when a change has visible UI impact and you want to post a `## Evidence` PR comment. Project-agnostic: it parameterizes on a `nix run`-style serve command, so it reuses across any project whose app boots that way. Covers the self-contained Playwright capture, video recording, ffmpeg transcode, GitHub-release hosting, and posting. Triggers on "post evidence", "screenshot the change", "PR evidence", "record a video of this", "capture the UI".
Provision and drive an ephemeral `pu` box — a throwaway Incus container used as a clean Linux host for CI, builds, and evidence capture. Use when you need to run something on a fresh remote box instead of the user's machine: `nix run` a build, run CI against a real host, capture screenshots/video off-machine, or reproduce on a pristine environment. Covers create/connect/scp/destroy, running remote commands, copying artifacts back, and the no-egress failure mode. Triggers on "pu box", "spin up a box", "run this on a box", "ephemeral host", "pu create/connect/destroy".
Reference for the `justci` runner — how to invoke a full pipeline, a single recipe, or a platform-pinned node from a project that depends on `juspay/justci`. Trigger when the user asks to "run justci", "run the pipeline", "re-run a check", or names a specific recipe by `<recipe>@<platform>`.
Use Pierre Computer Company's `@pierre/trees` (path-first file tree) and `@pierre/diffs` (shiki-based code/diff renderer) in Kolu. Pierre ships Preact/vanilla cores with optional React wrappers — Kolu consumes the vanilla classes and wraps them in thin SolidJS components. Trigger when: wiring up a file tree, rendering unified diffs or syntax-highlighted files, replacing `@git-diff-view`, or any mention of `@pierre/trees` / `@pierre/diffs` / "pierre library".
Kolu's project-wide default for filesystem monitoring is `@parcel/watcher`. Reach for this skill when adding or modifying any code that watches files or directories — recursive subtree watching, single-file observation, fs.watch alternatives, chokidar replacement, inotify/FSEvents/watchman backend selection, ignore globs, watcher debouncing, or refcounted shared subscriptions. Covers backend dispatch, the watchman invocation path, ignore handling, post-install reconciliation, and the failure modes Kolu's logger surfaces.
Diagnose Kolu client-side performance issues (memory leaks, high GPU, slow interactions) using chrome-devtools MCP + the Debug → Diagnostic info dialog + heap-snapshot analyzers. Triggers on "memory leak", "GPU memory", "tab bloat", "why is kolu slow", "debug performance", "zombie canvas", "WebGL leak", or any
