Explore and investigate ideas before committing to a change. Trigger: When the orchestrator launches you to think through a feature, investigate the codebase, or clarify requirements.
review-logging-patterns
by HugoRCD
Review code for logging patterns and suggest evlog adoption. Guides setup on Nuxt, Next.js, TanStack Start, Nitro, Hono, Cloudflare Workers, and standalone TypeScript. Detects console.log spam, unstructured errors, and missing context. Covers wide events, structured errors, drain adapters (Axiom, OTLP, PostHog, Sentry, Better Stack), sampling, and enrichers.
cts-triage
by gfx-rs
Run CTS test suites and investigate failures
unbrowse
by unbrowse-ai
API-native agent browser powered by Kuri (Zig-native CDP, 464KB, ~3ms cold start). Unbrowse is the intelligence layer — learns internal APIs (shadow APIs) from real browsing traffic and progressively replaces browser calls with cached API routes (<200ms). Three paths: skill cache, shared route graph, or Kuri browser fallback. 3.6x mean speedup over Playwright across 94 domains. Full Kuri API surface exposed (snapshots, ref-based actions, HAR, cookies, DOM, screenshots). Free to capture and index; agents earn from mining routes for other agents.

fixer
by petekp
Cold, methodical diagnostician for when you're stuck in agent-assisted app development. Call the fixer when: (1) You're in a loop with a coding agent and things keep getting worse, (2) Your project has accumulated so many agent-generated changes you've lost the thread, (3) Builds are broken and you can't figure out why, (4) You've tried multiple approaches and none are working, (5) You need someone to cut through confusion and give you a clear path forward. Triggers on: "I'm stuck", "nothing is working", "help me fix this", "I'm going in circles", "the agent keeps breaking things", "I've lost track of what's happening", "can you take a look at this mess", or any expression of frustration with agent-assisted development. The fixer does not commiserate — it diagnoses, intervenes, and unblocks.
bug-coverage-classifier
by phase-rs
Use when classifying a Phase bug report against a specific card's engine-authoritative parse_details. The primary job is validating that a card CLAIMS to support the misbehaving clause and then comparing the parsed AST against the Oracle text to confirm or refute that claim. Unsupported clauses are already known gaps and get deferred. Reads the same coverage data the Alt-hover overlay and card-bot render. Invoked by /bug-triage and /issue-clusterer.
akka-net-testing-patterns
by Aaronontheweb
Write unit and integration tests for Akka.NET actors using modern Akka.Hosting.TestKit patterns. Covers dependency injection, TestProbes, persistence testing, and actor interaction verification. Includes guidance on when to use traditional TestKit.
design-doc
by bdfinst
Produce a written design document in docs/specs/ with user approval before planning begins. Use this skill during the Research phase when a feature request, architectural change, or non-trivial task enters the pipeline. Ensures misunderstandings are caught before any planning or implementation work starts. Also use when the user says "brainstorm", "design", "spec", or "let's think through this".
help
