Generate commit messages following Conventional Commits format. Use when creating commits, writing commit messages, or the user asks to commit changes.

Use when: creating a new Relay-connected React component, defining a GraphQL fragment, or wiring a component to a query

Perform an intelligent review of geographic data PRs beyond schema validation. Use this skill whenever reviewing a data PR, performing code review on contributions, checking if data makes geographical sense, or assessing data quality. Trigger on: PR review requests for data changes, "review this PR", "does this look right", "is this data correct", quality assessment requests, geographic plausibility checks, suspicious pattern detection, or any pull request touching files in the contributions/ directory. This goes beyond schema validation to check real-world geographic accuracy.

Use when improving performance, latency, throughput, memory usage, or general efficiency. Start by defining target metrics, measuring comprehensively, attributing bottlenecks, validating with static analysis, and prioritizing macro-optimizations before micro-optimizations.

Use when adding or changing a Reborn integration — a new extension, a channel surface, model-callable tools, or a shared auth provider — or when deciding whether something is "a channel", "an extension", or "a tool". Maps the unified extension model (NEA-25) to the exact manifest sections, crates, seams, and tests.

Add a GettingStarted sample Step (a Server/Client pair) to the AG-UI .NET SDK that demonstrates one protocol feature the way we want users to write it. USE FOR: adding a new samples/GettingStarted/StepNN_<Name> Server+Client pair, wiring it into AGUI.slnx and the integration-test project, giving it a deterministic FakeChatClient for replay, and registering it in the Step tables in AGENTS.md / docs/architecture.md. DO NOT USE FOR: the replay/Verify integration-test mechanics (use agui-dotnet-integration-tests), the dojo scenarios under samples/AGUIClientServer (use agui-dojo), or protocol/wire changes the sample exercises (use agui-dotnet-wire-types / agui-dotnet-transport).

YAML wire format for json-render with streaming parser, prompt generation, and AI SDK transform. Use when working with @json-render/yaml, YAML-based spec streaming, yaml-spec/yaml-edit fences, or YAML prompt generation.

React PDF renderer for json-render. Use when generating PDF documents from JSON specs, working with @json-render/react-pdf, or rendering specs to PDF buffers/streams/files.

Author and run black-box benchmark cases for the Windmill AI generation modes (flow/app/script/cli/global) in ai_evals/. Use when adding or changing eval cases, or when running before/after benchmarks for AI chat / copilot changes.

Attempts ONE alternative fix for a bug, tests it empirically, and reports results. ALWAYS explores a DIFFERENT approach from existing PR fixes. Use when CI or an agent needs to try independent fix alternatives. Invoke with problem description, test command, target files, and optional hints.

Explore and understand Nx workspaces. USE WHEN answering any questions about the nx workspace, the projects in it or tasks to run. EXAMPLES: 'What projects are in this workspace?', 'How is project X configured?', 'What targets can I run?', 'What's affected by my changes?', 'Which projects depend on library Y?', or any questions about Nx workspace structure, project configuration, or available tasks.

Writing unit and integration tests for the tldraw SDK. Use when creating new tests, adding test coverage, or fixing failing tests in packages/editor or packages/tldraw. Covers Vitest patterns, TestEditor usage, and test file organization.

Writing release notes articles for tldraw SDK releases. Use when creating new release documentation, drafting release notes from scratch, or reviewing release note quality. Provides guidance on structure, voice, and content for release files in `apps/docs/content/releases/`.

Writing Playwright E2E tests for tldraw. Use when creating browser tests, testing UI interactions, or adding E2E coverage in apps/examples/e2e or apps/dotcom/client/e2e.

Reimplement the current branch on a new branch with a clean, narrative-quality git commit history. Use when asked to make a clean copy branch, clean up commit history by replaying work, or rebuild a branch as reviewable commits.

This skill should be used when the user asks to "create an MCP App", "add a UI to an MCP tool", "build an interactive MCP View", "scaffold an MCP App", or needs guidance on MCP Apps SDK patterns, UI-resource registration, MCP App lifecycle, or host integration. Provides comprehensive guidance for building MCP Apps with interactive UIs.

Mem0 provider for Vercel AI SDK (@mem0/vercel-ai-provider). TRIGGER when: user mentions "vercel ai sdk", "@mem0/vercel-ai-provider", "createMem0", "retrieveMemories", "addMemories", "getMemories", "searchMemories", "mem0 vercel", "AI SDK provider", "AI SDK memory", or is using generateText/streamText with mem0. Also triggers for Next.js apps needing memory-augmented AI. DO NOT TRIGGER when: user asks about direct Python/TS SDK calls without Vercel (use mem0 skill), or CLI terminal commands (use mem0-cli skill).

Pins or unpins a memory to protect it from pruning during dream consolidation. Use when a memory is critical and must never be removed, such as core preferences, important decisions, or immutable personal facts.

Diagnoses mem0 connectivity, API key validity, and memory read/write functionality. Use when memory operations fail, searches return empty, add_memory errors occur, MCP connection drops, or to verify the plugin is working correctly.

Searches and injects relevant memories into context before starting work on a task. Use when beginning a new task, switching context, or when project history, past decisions, or coding conventions need to be loaded.
