Use when writing ANY test, debugging flaky tests, making tests faster, or choosing Swift Testing vs XCTest. Covers unit tests, UI tests, async testing, test architecture.
Hot-reload Go apps with cosmtrek/air during development. Use when setting up dev workflows for Go HTTP servers, configuring .air.toml, or debugging hot-reload issues with SQLite, port binding, or file watchers.
GitHub Actions CI/CD for Rust+Node.js hybrid repos. Covers workflow structure, installable composite actions, artifact flow, caching, and dev versioning. Use when: (1) setting up or fixing GitHub Actions workflows, (2) adding CI for a Rust+Node.js project, (3) working with composite actions (setup-workspace, rust-cross-build, compute-version, wait-npm-propagation), (4) debugging CI failures, (5) setting up the cross-platform build matrix. Triggers on "CI", "workflow", "GitHub Actions", "cross-build", "artifact", or work in .github/workflows/.
Run, monitor, analyze, and debug LLM evaluations via nemo-evaluator-launcher. Covers running evaluations, checking status and live progress, debugging failed runs, exporting artifacts and logs, and analyzing results. ALWAYS triggers on mentions of running evaluations, checking progress, debugging failed evals, analyzing or analysing runs or results, run directories or artifact paths on clusters, Slurm job issues, invocation IDs, or inspecting logs (client logs, server logs, SSH to cluster, tail logs, grep logs). Do NOT use for creating or modifying evaluation configs.
Use version control as a craft — atomic commits, buildable history, useful PRs, bisect-friendly main, recoverable mistakes. Use this skill whenever the task involves writing commits or PRs, choosing a branching model, deciding rebase vs. merge, recovering from a force-push or accidentally-committed secret, debugging a regression with `git bisect`, structuring a long change as a series of small reviewable steps, or judging whether a repo's history is readable. Use it especially when reviewing commit messages, PR descriptions, branching strategies, or merge policies. Built on Tim Pope and Chris Beams on commit messages, Paul Hammant on trunk-based development, Vincent Driessen on GitFlow (and his 2020 note retiring it for SaaS), Linus Torvalds on never rebasing public commits, and the Google Engineering Practices CL guide.
Delegate menial, well-scoped coding tasks to a cheap Qwen-backed subagent via the `claude-9arm` command instead of burning Claude tokens/quota. Use when the work is mechanical and low-risk — bulk renames, formatting, boilerplate, find-replace, grep-style search & summarization, reading/condensing logs or files, test/docstring/comment scaffolding, or running builds/linters/tests and reporting pass-fail. Also use when the user says "use qwen", "delegate this", "send it to 9arm/qwen", or "do this cheaply". Do NOT use for architecture, design, debugging judgment, security-sensitive edits, or anything needing this conversation's context.
Use when debugging, benchmarking, or profiling leads into Kotlin or Jetpack Compose source before the cause is known, or when a broad Kotlin or Compose review spans multiple design concerns.
Harbor CLI command reference and usage patterns. Covers harbor run, harbor jobs, harbor trials, harbor datasets, harbor adapters, harbor tasks, harbor view, harbor sweeps, harbor traces, harbor cache, and harbor admin commands. Use this skill whenever running Harbor evaluations, managing datasets, viewing results, debugging tasks, exporting traces, or working with any harbor CLI command. Also use when constructing harbor command lines, looking up flag names, or troubleshooting CLI errors.
Connect Claude Code to an existing Chrome browser via CDP (Chrome DevTools Protocol). Zero dependencies — uses Node 22 built-in WebSocket. Attach to any Chrome running with --remote-debugging-port, then navigate, click, type, screenshot, evaluate JS, read accessibility tree, and monitor console/network. Use when you need to interact with a browser the agent already started, control an existing Chrome instance, or drive browser automation without Playwright MCP. Triggers on: cdp connect, connect to browser, connect to chrome, attach to browser, interact with browser, drive browser, browser automation, control chrome, connect 9222.
Guidance for building, debugging, and reviewing next.js apps that use cloudinary through next-cloudinary and the cloudinary node sdk v2. Use for tasks involving CldImage, CldVideoPlayer, CldUploadWidget, CldUploadButton, CldOgImage, GetCldImageUrl, GetCldOgImageUrl, GetCldVideoUrl, signed uploads, server uploads, deletes, transformations, responsive images, overlays, social cards, environment variables, and common Cloudinary errors.
Cartographic principles for MapLibre GL JS — label and symbol legibility on imagery vs. vector basemaps, figure-ground for point icons, styling vector roads over aerial imagery, visual hierarchy, typography (glyphs/font stacks), sprites and route shields, layer ordering for data injection, and accessibility. Use when styling a map, choosing text or symbol colors, making markers or roads readable on satellite/aerial imagery, setting up fonts or icons, debugging shields, or ordering layers correctly.
Cryptographic primitives used by the Midnight node — Blake2-256 hashing, sr25519/ECDSA/Ed25519 signatures, twoxhash storage keys, and how they map to consensus, P2P, and state. Use when debugging node crypto, signature verification, or hash function choices.
