Explore MCP Servers & Agent Skills

io.github.temporalio/temporal/review

Review code for common issues. Use when reviewing PRs, suggesting code changes, or when user asks to review code.

io.github.lightdash/lightdash/frontend-style-guide

Apply the Lightdash frontend style guide when working on React components, migrating Mantine v6 to v8, or styling frontend code. Use when editing TSX files, fixing styling issues, or when user mentions Mantine, styling, or CSS modules.

io.github.openclaw/openclaw/xurl

xurl CLI for authenticated X posts, replies, reads/search, DMs, media upload, followers, auth status, or raw v2 API calls.

io.github.wshobson/agents/review-agent-setup

Configure human-in-the-loop gating for AI agent review actions in Claude Code. Use when setting up a project where an agent may post PR reviews, comments, merges, or edit CI configuration, and you want a cryptographically auditable approval trail with Cedar-enforced gates.

io.github.dzhng/skills/refactor-clean

Refactor cleanly instead of layering sediment. Use when a change reveals duplicated concepts, local adapters, obsolete owners, compatibility wrappers, parallel abstractions, an over-large module that has accreted many responsibilities, or "just tack this on" pressure in any code area.

io.github.Stirling-Tools/Stirling-PDF/feature-walkthrough

Explain the full logic and process of the current branch end-to-end so someone with no prior knowledge of the task can understand, review, and reproduce it. Scopes the change from the branch diff, traces the flow across every layer it touches (frontend tool/hook/component, Java controller/service/endpoint, Python engine, config, i18n, tests), and produces a self-contained walkthrough document with Mermaid diagrams (sequence/flow/architecture), annotated file map with clickable references, before/after behavior, screenshots where a UI is involved, a "try it locally" section, and edge cases/risks. Use when asked for a feature or branch walkthrough, "explain what this branch does", a design/logic writeup, PR reviewer onboarding, or a hand-off doc. Pass --html to also emit a rendered HTML version; --no-screens to skip screenshots.

io.github.EpicenterHQ/epicenter/testing

Test file conventions: setup functions, factories, Result assertion helpers, organization, type testing, naming, and pruning low-value tests. Use when: "write tests", "add a test", "fix this test", "delete tests", "prune tests", "audit tests", or modifying *.test.ts files.

io.github.EpicenterHQ/epicenter/refactoring

Per-change refactoring mechanics: count callers exactly, decide inline vs keep, collapse duplicate switch branches, route raw access through a single typed boundary, surgical one-change-per-commit, post-refactor straggler sweep for stale JSDoc and dead exports. Use when actually editing code to clean it up, when deciding whether a 1-caller helper earns its keep, or when planning a sequence of small refactor commits. For the smell catalog use code-audit; for session-long simplification use collapse-pass.

io.github.yv1ing/Z3r0/sqlmap

Use for authorized SQL injection testing with the sqlmap CLI, including detection, DBMS fingerprinting, request replay, and extraction checks against in-scope web targets.

io.github.FradSer/dotclaude/refactor

Executes automated refactoring for specific files, directories, or semantic queries. This skill should be used when the user asks to refactor specific files or directories, simplify recently changed code, clean up dead code in a limited scope, or invokes "/refactor".

io.github.vercel/next.js/insight-error-page

Write or audit an insight-kind error page for the Next.js dev overlay. Use when creating a new `errors/<slug>.mdx` page, auditing an existing one, or checking that a page matches the framework fix cards. Covers page structure, title alignment, FixCard cards with Copy prompt button, code snippets, terminology verification against canonical docs, and Vercel technical writing style.

io.github.jeremylongshore/claude-code-plugins-plus-skills/portaljs-deploy

Deploy a PortalJS portal to PortalJS Arc — Datopian-managed static hosting on Cloudflare. Builds a static export, uploads it, and returns a live <slug>.arc.portaljs.com URL. One command, one target.

io.github.aiskillstore/marketplace/backend-fastapi

Documentation for the FastAPI backend, endpoints, and dependency injection.

io.github.feast-dev/feast/feast-architecture

Internals of the Feast codebase — how each component works, where the key abstractions live, and the data flow through the system. Use when asked how feast apply works, how the registry stores data, how materialization moves data, how get_online_features retrieves features, how the feature server works, how the Kubernetes operator manages deployments, or when navigating the codebase to understand where to make a change.

io.github.microsoft/vcpkg/review-vcpkg-prs-today

Review open non-draft microsoft/vcpkg pull requests updated in the last 30 days. Use when asked for batch triage, per-PR review reports, an index grouped by verdict, or grouping competing PRs that modify the same port.

io.github.microsoft/vcpkg/review-vcpkg-pr

Review a microsoft/vcpkg pull request end-to-end.

io.github.mohitagw15856/pm-claude-skills/sql-query-explainer

Explains, optimises, writes, and documents SQL queries. Use when asked to explain a SQL query, optimise slow SQL, translate SQL to plain English for non-technical stakeholders, write a query from a natural language description, or produce query documentation. Produces plain-English explanations, annotated optimised queries, or a data dictionary covering output shape, assumptions, and known limitations. Works across PostgreSQL, MySQL, BigQuery, Snowflake, and standard SQL.

io.github.jleechanorg/claude-commands/automation-audit

Audit automation job runs, logs, PR processing metrics, and AI-authored remote commits.

io.github.wshobson/agents/rag-implementation

Build Retrieval-Augmented Generation (RAG) systems for LLM applications with vector databases and semantic search. Use when implementing knowledge-grounded AI, building document Q&A systems, or integrating LLMs with external knowledge bases.

io.github.lobehub/lobehub/agent-tracing

Agent tracing CLI for execution snapshots. Use for agent-tracing, traces, snapshots, LLM call inspection, context engine data, agent step analysis, execution debugging, or pulling remote/production traces ("拉线上 tracing") by operation id. Also the first stop for debugging agent tool calls — wrong or missing tool_calls, unexpected tool arguments or results, which tools were available at a step, or why a tool ran where it did.

io.github.home-assistant/core/ha-pr-reviewer

Reviews Home Assistant GitHub pull requests and provides feedback comments. This is the top skill to use for reviewing Pull Requests from GitHub.

io.github.serverless/serverless/serverless-sandboxes

Build, run, and operate isolated or ephemeral compute on AWS with the Serverless Framework `sandboxes` feature (AWS Lambda MicroVMs). Use whenever the user wants to execute untrusted or AI-generated code, run per-session, per-agent, or per-tenant isolated workloads, build a code-execution backend, or mentions Firecracker MicroVMs, the `sandboxes` block in serverless.yml, `serverless dev --sandbox`, `invoke --sandbox`, `logs --sandbox`, RunMicrovm, or AWS Lambda MicroVMs. Trigger even when the user names neither "Serverless Framework" nor "sandbox" but describes an isolated AWS execution environment.

io.github.ChromeDevTools/devtools-frontend/devtools-ux-writing-refactor

Refactor user-facing UIStrings and localization comments in a DevTools module folder according to UX writing guidelines (child task of b/40799900). Use when simplifying wording, checking sentence case, or improving L10n comments in UIStrings for a specific folder or issue. Don’t use for general code changes or non-UIStrings files.

io.github.nginx/kubernetes-ingress/nic-docker-images

Docker image build system, Dockerfile structure, image variants, build scripts, and Makefile targets for NIC. Use when building container images, modifying the Dockerfile, adding new image variants, debugging image builds, or working with build scripts.
