Explore MCP Servers & Agent Skills

io.github.comet-ml/opik/local-dev

Local development environment setup and commands. Use when helping with dev server, Docker, or local testing.

io.github.comet-ml/opik/writing-e2e-tests

Use when a developer wants to add, write, or create an end-to-end test for an Opik feature, page, or branch — e.g. "add an e2e test for the experiments comparison page", "write a test for the feature I just built", "e2e test for this branch", "cover the dataset items flow with a test". Runs the full loop in tests_end_to_end/e2e/ — analyze the feature and frontend code, explore the live UI with the Playwright MCP, write the Page Object Model + spec, and run it locally until green.

io.github.fastrepl/anarlog/sqlite-schema-design

Design or review schemas for `crates/cloudsync` using SQLite Sync constraints, not generic SQLite advice. Use when adding synced tables, changing synced columns, or planning CloudSync-safe migrations.

io.github.fastrepl/anarlog/reactive-sqlite-ui

Build SQLite-backed reactive UI in `apps/desktop` using stable patterns for reads, selection, forms, writes, and loading states. Use when implementing or reviewing screens built on `useDrizzleLiveQuery` and SQLite mutations.

io.github.glebis/claude-skills/automation-advisor

Interactive automation decision advisor using the Automation Decision Matrix framework. Use when the user asks "should I automate this?", wants to evaluate an automation opportunity, calculate automation ROI or break-even, or requests an automation decision analysis. Guides a structured questionnaire, scores four dimensions, applies override checks, and generates an Obsidian-formatted report with a visual decision diagram.

io.github.mattpocock/skills/migrate-to-shoehorn

Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.

io.github.mattpocock/skills/design-an-interface

Generate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".

io.github.mattpocock/skills/writing-great-skills

Reference for writing and editing skills well — the vocabulary and principles that make a skill predictable.

io.github.ClickHouse/ClickHouse/review

Review a ClickHouse Pull Request for correctness, safety, performance, and compliance. Use when the user wants to review a PR or diff.

io.github.langfuse/langfuse/refactor-react-effects

Refactor avoidable React useEffect usage in Langfuse frontend code. Use when adding, reviewing, or removing effects; initializing forms or local UI state from query data; synchronizing client and server state; moving mutations or async workflows out of components; cleaning every effect from a frontend submodule; or reviewing whether an effect has a valid external-system owner.

io.github.langfuse/langfuse/frontend-large-feature-architecture

Use when building, changing, or refactoring large Langfuse frontend features, virtualized lists, large tables, controller components, local feature state, Zustand stores, row selection, high-frequency UI state, or rendering-performance issues. Also read BEFORE writing any useEffect (especially one that syncs fetched data into state), wiring form initialValues/defaultValues from loaded data, or adding useCallback/useMemo.

io.github.langfuse/langfuse/code-review

Shared code review workflow for Langfuse. Use when reviewing a PR, branch, diff, or local changes for correctness, regressions, risk, and missing tests. Start with references/review-checklist.md for repo-specific review rules and use package AGENTS.md files plus any matching shared skills when the change touches those areas.

io.github.handsontable/handsontable/code-graph

Query the pre-built code-review-graph knowledge graph (Tree-sitter, whole monorepo) instead of walking call chains with Grep+Read — 2-6x cheaper, and it catches dynamic dispatch that grep misses. Use for ANY task that spans multiple files, even when the user never mentions a graph or asks for it - fixing or tracing a bug ("fix this bug", "why does X happen", "trace this"), exploring unfamiliar code ("how does X work", "who calls X", "what imports Y", "where is X used or handled"), planning or doing a refactor ("rename X", "is it safe to change or remove X", "what would break", "blast radius", "find dead code"), or reviewing changes ("review this PR", "review this branch or diff"). If you are about to Grep for a symbol to find its callers, callees, or importers, stop and use this skill instead.

io.github.latitude-dev/latitude-llm/api-endpoints

Adding or changing API operations in `@repo/operations`. One source of truth (`defineOperation` + a Zod schema) becomes an HTTP endpoint, an OpenAPI operation, an MCP tool, TS + Python SDK methods, a `latitude` CLI command, and an in-process agent tool — descriptions and contracts must be written with all of these readers in mind.

io.github.modu-ai/moai-adk/moai-domain-backend

Backend development specialist covering API design, database integration, microservices architecture, and modern backend patterns. Use when designing APIs, implementing server logic, authentication, or authorization.

io.github.camunda/camunda/frontend-operate-migrator

Use when migrating any Operate page from operate/client/ to the orchestration cluster webapp. Always read frontend-migrator first — this skill adds Operate-specific overrides, the migration loop protocol, and page-by-page context.

io.github.daiki-beppu/youtube-automation/automation-release

Use when 本リポジトリの新規リリースを作成するとき。「リリースして」「/automation-release」「suno-helper をリリースしたい」「ext-v0.2.2 を出したい」で発動。Python 本体（vX.Y.Z）と Chrome 拡張（ext-vX.Y.Z）を判定し prepare / publish に自動分岐。グローバル /release は使わない。下流追従は /automation-update、拡張のインストールは /ext-install
