Generate architecture procedurally in Three.js and film it assembling — a small geometry vocabulary that builds pagodas, castles, domes and spires from parameters instead of mesh files, hip roofs with flying eaves driven by a single profile function, and a clipping-plane build animation where everything below a rising line is finished work and scaffolding stands above it. Use for construction studies, architectural title sequences, procedural landmarks, or any hero object that should build itself rather than fade in.

Build a live Three.js landscape that stays quiet behind a subject — a noise heightfield on a polar grid so resolution follows the lens, ground coloured by slope and moisture rather than by texture, instanced GPU grass whose wind costs nothing on the CPU, scattered stones, a gradient sky dome, a star field you can actually see, and a time-of-day system that cross-fades instead of cutting. Use for hero backdrops, product stages, scroll worlds, or any scene where a building, object, or figure has to sit in a place rather than float on a gradient.

Create a dark monochrome procedural background with enlarged square pixels and visible Bayer-style ordered dithering. Use when a page needs an atmospheric near-black dither field, broad organic waves or cloud masses, and restrained gray-white highlights behind framed UI, hero content, or data overlays.

Build a cursor trail whose spacing stays constant at any hand speed, by emitting motes per unit of distance travelled rather than on a timer, so a flick draws the same continuous ribbon as a crawl instead of breaking into scattered dots. Covers sub-segment placement, the ring-buffer ordering trap, the idle breath a distance emitter needs, anchoring the trail to the screen in a 3-D scene, scaling scatter against the plane it hangs on, coasting instead of stopping dead, touch and reduced-motion fallbacks, and why moving the emitter to a DOM overlay to raise its z-index costs more than it buys. Use for cursor wisps, pointer sparks, embers, magic trails, comet tails, plankton, dust, or any mote trail that must stay legible however fast the hand moves.

Build reversible scroll-controlled visual transformations with a pinned or sticky stage, normalized progress, and video, image-sequence, canvas, SVG, or DOM renderers. Use for hero transformations, product assembly, interface state walkthroughs, object rotation, diagrams, or photo sequences that must move forward and backward with native scrolling.

Create a layered CSS progressive blur (top or bottom) using multiple backdrop-filter masks for depth and softness. Use when asked for “progressive blur”, “gradient blur overlay”, or stepped blur masks that fade from an edge of the viewport.

Guide performance profiling for Apple platform apps with Instruments, Xcode diagnostics, and MetricKit. Use when investigating app hangs, stutters, high CPU, memory leaks, memory growth, OOM crashes, slow launch, battery drain, thermal issues, App Store performance readiness, or when adding os_signpost and measurement hooks.

Claw system administration: service management, IM connections, logs, cron, and workspace diagnostics. Use when the user asks to manage claw services, connect/disconnect IM platforms, view logs, or perform system-wide operations.

Install software any way the system allows. Recommends `x install` — one front door listing every method and picking the best; plus `x eget`/`x env use`/`x pixi` channels and system package managers with mirror switching. All x-cmd channels install in $HOME — no sudo, no pollution. Use for "install", "apt", "brew", "eget", "pixi", "package manager", "mirror".

Search and read Wikipedia via x wkp — MediaWiki API, no API key, zero install; query, extract, suggest, and DDG route in one module. Load for wiki, wikipedia, encyclopedia lookup, article summary.

Deep adversarial code review using the 8-lens review constitution. Examines diffs for correctness, security, completeness, and MockServer-specific concerns (ByteBuf leaks, module boundaries, javax/jakarta compatibility, ring buffer sizing). Use when performing pre-commit reviews, quality-loop iterations, or on-demand code audits. Loaded by review-cheap and review-final agents.

Builds and pushes the MockServer Maven CI Docker image locally. Covers corporate CA certificate setup, architecture selection (amd64 vs arm64), buildx gotchas with corporate TLS proxies, and Docker Hub authentication. Use when the user says "build docker image", "push maven image", "rebuild CI image", "docker build", "push to docker hub", or needs to manually build/push the mockserver/mockserver:maven image outside of CI.

Investigates AWS infrastructure issues affecting Buildkite build agents (EC2, AutoScaling, Lambda). Returns structured JSON to the parent for formatting. Triggers when users ask about build agents not running, EC2 issues, ASG scaling problems, or infrastructure health.

Guide for testing bug reproductions against locally-built MSBuild. Use this when you have a repro project and want to verify a fix works before submitting a PR.

Checks whether a self-hosted Lightdash upgrade is safe to run, and reads the tooling's answer without over-reading it. Use when upgrading a self-hosted instance, planning a maintenance window, answering "is this upgrade safe", or recovering a failed, hung, parked or lock-stuck migration — covers `lightdash upgrade-check` and `migrate preflight`, how to gate on their exit codes and JSON, and the readings that look calm but mean "could not check".

Test and assess an open Renovate dependency-bump PR. Picks the first open Renovate PR, checks out the branch, starts the app, exercises code paths affected by the upgraded package, reviews the changelog and (if needed) the upstream source diff, and reports whether the bump is safe to merge. Use when asked to "test a renovate PR", "triage renovate", "assess a renovate bump", or "check a dependency upgrade".

Runs Azure CLI commands in a terminal. Use this skill when you need to execute az CLI commands such as checking authentication, querying Log Analytics, managing deployments, or inspecting Azure resources.

Audit and update docs/copilot/ documentation to accurately reflect current VS Code AI capabilities. Use when: competitive analysis reveals gaps, product launches new features, docs use outdated framing, or keyword coverage needs strengthening for discoverability by users and AI agents. Produces a gap analysis plus targeted edits across affected files.

This skill should be used when the user wants to "create a new Python ADK recipe", "scaffold a new Python recipe", "generate a new Python recipe in contrib", "add a new Python recipe to the adk-recipes repository", or "create a Python adk recipe". It utilizes an automated script to copy template files and resolve basic placeholders.

Generates a lightweight `tests/test_runnability.py` for a Python recipe. The test just imports the recipe's agent module and asserts that `root_agent is not None` (and `app is not None` if the module defines one). The skill parses agent.py with `ast` to figure out which import-time side effects need mocking (`vertexai.init`, `google.auth.default`) and which env vars need setting (`GOOGLE_CLOUD_PROJECT`, `INTEGRATION_TEST`), and only emits the boilerplate the recipe actually needs. Runs in dry-run (report + preview) and apply (write to disk) modes. Use when the user wants to "add a runnability test", "generate test_runnability.py", "create a smoke test for the recipe", or fix the missing-required-file failure from `python-validate-recipe.yml`.
