Use when committing code changes in Ruby or Ruby on Rails projects — guides commit message structure, type selection, and body content following Conventional Commits format

Survey a whole React codebase as a senior React engineer, using React Doctor's scan as evidence, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute. Read-only on source code — it plans improvements, it does not apply them. Use when the user asks to "improve the React code", "audit this codebase", "make this app faster / more robust", or wants a roadmap of fixes rather than a review of a single diff. For a regression check or a fix-it-now pass, use the `react-doctor` skill instead.

Use this skill to interactively scope a maintenance idea into a properly formatted task for the Android Agentic Maintenance Backlog. Invoke when the user wants to add a task to the maintenance backlog, scope a new maintenance idea, or says things like "I want to add something to the backlog", "help me scope a maintenance task", or "can we add this as a maintenance item".

Use when the user mentions App Store screenshot validation, screenshot review, checking screenshots before submission, or verifying screenshot dimensions and content.

Use the ChatJS React Query v5 lazy-prefetch pattern without blocking server rendering. Use when prefetching tRPC queries in Next.js Server Components or changing query dehydration and hydration behavior in apps/chat.

Transforms conversations and discussions into structured documentation pages in Notion. Captures insights, decisions, and knowledge from chat context, formats appropriately, and saves to wikis or databases with proper organization and linking for easy discovery.

Use this skill when the user wants to set up, inspect, or update their BestBlogs interest profile and onboarding state (cold start). Triggers include "帮我做 BestBlogs 冷启动 / 设置兴趣标签 / 看我现在的画像 / bestblogs 的 onboarding", "set up my BestBlogs profile", "what topics have I chosen on BestBlogs". Invokes the `bestblogs` CLI.

Use this skill when the user asks about today's daily brief, morning digest, or BestBlogs highlights. Triggers include "今天早报 / 今日早报 / BestBlogs 早报 / 今天有啥好文 / 今日精选 / 给我看早报", "today's brief", "today's digest", "BestBlogs morning brief", "today's highlights on BestBlogs", "what's in today's brief". Invokes the `bestblogs` CLI.

Perform Fallow's comprehensive pre-merge review. Use after implementation or when asked to review a branch, pull request, or diff.

Use when the user asks about code health, code quality, complexity, technical debt, risky or hard-to-maintain files, what to refactor next, untested hotspots, or coverage gaps in a Repowise-indexed codebase (.repowise/ directory exists). Also use for before/after health reads when planning or finishing a refactor.

Use when exploring, understanding, or answering questions about a codebase that has Repowise indexed (a .repowise/ directory in the project root). Activates for "how does X work", "explain the architecture", "where is Y implemented", "what does this module do", or any task that needs an understanding of structure before diving into source files.

Use when the user asks about code health, code quality, complexity, technical debt, which files are risky or hard to maintain, what to refactor next, untested hotspots, or coverage gaps in a Repowise-indexed codebase (.repowise/ directory exists). Also use to get a before/after health read when planning or finishing a refactor.

Use when running unit tests in the VS Code repo. Covers the runTests tool, scripts/test.sh (macOS/Linux) and scripts/test.bat (Windows), and their supported arguments for filtering, globbing, and debugging tests.

Analyze V8 heap snapshots to investigate memory leaks and retention issues. Use when given .heapsnapshot files, asked to compare before/after snapshots, asked to find what retains objects, or investigating why objects survive GC. Provides snapshot parsing, comparison, retainer-path helpers, and scratchpad scripts.

Capture and search thoughts against a self-hosted Open Brain over plain HTTPS, with no MCP transport involved. Use this skill in environments where Claude Code's MCP feature is disabled or the network blocks remote MCP endpoints, but the brain stack from the companion `local-brain-no-mcp` recipe is reachable on the local network. Triggers: prompts like "remember this", "save that for later", "what did I note about X", "search my brain for Y", "what thoughts touched on Z", or any explicit request to record or recall personal memory.

Upload files to Cloudflare R2, AWS S3, or any S3-compatible storage (like MinIO) and generate secure, time-limited presigned download links with configurable expiration, typically set to 5 minutes. Use when the user needs to upload a file to cloud storage and get a shareable link, or mentions R2, S3, presigned URLs, temporary links, or file uploads with expiration.

Add a new third-party service to the privacy policy generator. Trigger when user says: "add {name} service", "add third party service", "add 3rd party service", "add new service entry", or when a user wants to contribute a new service to the app.

Primary skill for composing, drafting, or refining any outbound Slack content. Use this whenever the task will require using `slack_send_message`, `slack_send_message_draft`, or `slack_create_canvas`. Use `slack` to read or analyze Slack context; use this skill to produce the final outgoing message.

Create a daily Slack digest from selected channels or topics. Use when the user asks for a daily Slack recap or summary of today's Slack activity.
