-
irahardianto Skill Performance Optimization Principles 3Apply performance optimization principles when profiling, benchmarking, or optimizing hot paths. Covers the measure-first methodology, identifying bottlenecks, caching strategies, and when to stop optimizing. For hands-on profiling workflows, use the perf-optimization skill instead.
-
irahardianto Skill Concurrency And Threading Principles 3Apply concurrency and parallelism patterns when implementing goroutines, async/await, threads, channels, mutexes, worker pools, or any concurrent data access. Covers race condition prevention, deadlock avoidance, and message passing.
-
irahardianto Skill Logging And Observability Principles 3Apply structured logging and observability implementation patterns when adding log statements, configuring loggers, implementing correlation IDs, or setting up telemetry. Covers log levels, structured fields, context propagation, and language-specific logger setup.

archibate Skill Fresh Arch 3Architecture design reasoned forward from requirements. Use when the user wants a fresh-mind design pass — "design an architecture for", "how would you build", "redesign from scratch" — or when repeated follow-up patches accumulate on the same module. Repeated follow-up patches landing on the same module (~3rd) → stop patching, invoke this skill to re-derive from the full requirement set.

dragoon0x Bundle Spacing 4Generate a spacing scale token file based on the spacing grid detected by /scan (4px, 8px, etc). Produces an 8-step t-shirt scale (xs/sm/md/lg/xl/2xl/3xl/4xl) anchored on the grid. Use when the user wants to formalize spacing tokens or scaffold a layout system. Defaults to dry-run; pass --apply to write. Run as `node ~/.claude/skills/dragoon/skills/spacing/scripts/spacing.js`.

dobroslavradosavljevic Bundle Oxfmt 4Build, review, debug, configure, migrate, teach, or plan Oxfmt JavaScript/TypeScript formatting with current Oxc docs and a full usage guide. Use for oxfmt how-to, oxfmt.config.ts, defineConfig, .oxfmtrc.json, Prettier migration, --check/--write, printWidth, sortImports, sortTailwindcss, sortPackageJson, ignorePatterns, oxfmt-ignore, language support, Biome migration, Vite+ fmt, editors, CI format gates, and day-to-day format workflows.
-
dobroslavradosavljevic Bundle Tanstack Start Architecture 4Enforce portable TanStack Start app architecture: file-route trees, page folders with index.tsx, route colocation (-components/-hooks/-lib), reuse-gated src/modules, naming, and import boundaries. Use when scaffolding a Start app or feature, adding pages/layouts, reviewing or reorganizing route/module layout, or when the user asks for tanstack-start-architecture / Start house style. Optional with-* overlays for generated OpenAPI clients, Better Auth client, TanStack Query, route gates, TanStack Form, env, client authorization, UI package, Effect, and Vitest.

nanocoai Skill Add Whatsapp 4Add WhatsApp as a channel. Can replace other channels entirely or run alongside them. Uses QR code or pairing code for authentication.
-
everyinc Bundle Ce Ideate 3Generate and evaluate grounded ideas. Use when the user wants ideas, improvements, or surprising directions before choosing one to develop. Not for refining an idea they already have (ce-brainstorm) or judging one already on the table (ce-pov).
-
everyinc Bundle Ce Compound 3Document a solved problem as a durable repo learning. Use when verified work produced non-obvious reasoning absent from its final code, tests, or existing docs; avoid routine fixes whose artifacts already explain the lesson.
-
everyinc Bundle Ce Brainstorm 3Explore vague or ambitious ideas into a right-sized requirements-only unified plan. Use when the user wants to brainstorm, scope what to build, or needs collaborative product framing before planning. Also use when they must scope work in territory they do not know, or ask for a blindspot pass. Not for executing already-specified work — implementation, debugging, or code review with no product scope left to decide. Not for a verdict on whether to adopt or switch to a named external technology, library, or platform; that is ce-pov.
-
everyinc Bundle Ce Compound Refresh 3Refresh the repo's captured learnings against the current codebase. Use when auditing stale, overlapping, superseded, or drifted learnings; avoid general refactor, debugging, or code review unless the learnings store is explicit.

-
fabioc-aloha Skill Anti Hallucination 4Prevent fabricated facts, invented APIs, and citation confabulation at the point of generation. Use when generating factual claims, code examples, API references, library names, configuration values, error messages, or citations — anything where 'sounds plausible' is not the same as 'is real'.
-
fabioc-aloha Skill Terminal Command Safety 4Provides terminal output-capture, hung-command, and platform-behavior procedures while the resident instruction retains the Backtick Hazard floor. Use when a command may lose output, hang, need interaction, or depend on host execution behavior.
