llm-judge
by existential-birds
LLM-as-judge methodology for comparing code implementations across repositories. Scores implementations on functionality, security, test quality, overengineering, and dead code using weighted rubrics. Used by /beagle:llm-judge command.

Bridging Observables and Signals using toSignal and toObservable.
Product Requirements
by HoangNguyen0403
Expert process for gathering requirements and drafting PRDs (Iterative Discovery).
long-eval
by bdfinst
Run an eval that takes longer than one cloud-session container lifetime — agent calibration, prompt A/B sweeps, judge-panel scoring — so it survives the frequent container recycles that kill in-process work. Use when the user says "run this long eval", "the eval keeps dying on restart", "make the eval survive restarts", "resume the eval", "keep the eval alive", or when a full-corpus calibration/benchmark will clearly outlast a single session. Ships a restart-durable engine + CLI so nothing is re-invented per eval.
apply-test-doubles
by bdfinst
Apply /cd-test-architecture's Step 4b build-vs-document decision logic against an existing, saved assessment report — or, when no valid report path is given, against a target to assess first — without re-running the full Steps 0-6 assessment each time. Use when the user wants to revisit or change a component's Build/Document choice from a saved cd-test-architecture report, says "apply the test doubles", "re-run Step 4b", "change the build-vs-document decision", or cites the /apply-test-doubles <path> command from a test-double setup guide.
performance-metrics
by bdfinst
Log task completion data to .claude/metrics/. Use at the end of every task to record tokens, cost, agents used, rework cycles, and hallucination events. Also use for periodic reporting to identify efficiency and quality trends.
skill-creator
by vercel-labs
Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.
gpt-researcher
by assafelovic
GPT Researcher is an autonomous deep research agent that conducts web and local research, producing detailed reports with citations. Use this skill when helping developers understand, extend, debug, or integrate with GPT Researcher - including adding features, understanding the architecture, working with the API, customizing research workflows, adding new retrievers, integrating MCP data sources, or troubleshooting research pipelines.

dev
by atopile
"LLM-focused workflow for working in this repo: compile Zig, run the orchestrated test runner, consume test-report.json/html artifacts, and discover/debug ConfigFlags."
hypogenic
by jimmc414
Automated hypothesis generation and testing using large language models. Use this skill when generating scientific hypotheses from datasets, combining literature insights with empirical data, testing hypotheses against observational data, or conducting systematic hypothesis exploration for research discovery in domains like deception detection, AI content detection, mental health analysis, or other empirical research tasks.
claude-setup-audit
by codemie-ai
This skill should be used when the user asks to "audit my claude setup", "check my claude configuration", "assess my claude code setup", "audit claude", "review my .claude folder", "is my claude setup correct", "check repo health", "assess my skills quality", "review my agents", "check my CLAUDE.md", "validate my hooks", "audit claude configuration", "check my MCP config", "how good is my claude setup", "scan my .claude folder", or wants a comprehensive quality assessment of all Claude Code components in a repository. Evaluates skills, subagents, CLAUDE.md rules, commands, hooks, and MCP configuration against established best practices. Produces a graded health report (A–F per component) with good/bad example references and prioritized recommendations.
adcs-access-and-relay
