io.github.codestable/CodeStable/cs-refactor

Refactor 主入口。触发：优化/重构/拆分/性能/代码太长，且不改变行为、不新增需求。不要用于新增功能(cs-feat)、修复 bug(cs-issue)、对外文档(cs-docs)、大需求拆解(cs-epic)。

io.github.exceptionless/Exceptionless/backend-testing

Use this skill when writing or modifying C# tests — unit tests, integration tests, or test fixtures. Covers xUnit patterns, AppWebHostFactory for integration testing, FluentClient for API assertions, ProxyTimeProvider for time manipulation, and test data builders. Apply when adding new test cases, debugging test failures, or setting up test infrastructure.

io.github.exceptionless/Exceptionless/backend-architecture

Use this skill when working on the ASP.NET Core backend — adding controllers, services, repositories, validators, authorization, WebSocket endpoints, jobs, Foundatio infrastructure, configuration, or Aspire orchestration. Prefer this as the backend entrypoint for project layering, C# conventions, logging, ProblemDetails, security-sensitive config, and OpenAPI baseline updates.

io.github.OpenBMB/PilotDeck/frontend-slides

Create animation-rich browser-based HTML presentations from scratch, enhance existing HTML decks, or convert PowerPoint files into web presentations. Use only when the requested deliverable is HTML or a browser presentation; do not use when the user needs an editable native .pptx file.

io.github.PostHog/posthog/writing-evals

Teaches how to write and run evals on the `products/posthog_ai/eval_harness/` harness — sandboxed agent suites that execute the real coding agent in a Docker or Modal sandbox against a seeded Hedgebox project, and one-shot suites that score a single in-process model invocation per case. Use when adding or changing eval suites, cases, scorers, seeders, or synthesizers under `products/posthog_ai/evals/` or `products/*/evals/`, when touching the harness under `products/posthog_ai/eval_harness/`, or when running or debugging those evals (`hogli evals`). Covers suite kinds and discovery, case anatomy, the seeder/synthesizer split, the one-branch scorer patterns, and how to read results. Not for `ee/hogai/eval/ci/` pytest evals, and not for the LLM Analytics product's evaluation features.

Use when interacting with MCP servers, executing tools, triaging findings, performing security reviews, debugging enterprise-managed authorization, deciding whether a CLI finding is real or overstated, or turning inspection output into an engineer-facing report with severity and confidence.

io.github.cartography-cncf/cartography/refactor-legacy

Convert a legacy handwritten-Cypher Cartography sync (`load_*` / `cleanup_*` JSON jobs) into the modern declarative data model (`load()`, `GraphJob.from_node_schema()`).
