Build ChatGPT apps with interactive widgets using mcp-use and OpenAI Apps SDK. Use when creating ChatGPT apps, building MCP servers with widgets, defining React widgets, working with Apps SDK, or when user mentions ChatGPT widgets, mcp-use widgets, or Apps SDK development.
**MANDATORY for ALL MCP server work** - mcp-use framework best practices and patterns. **READ THIS FIRST** before any MCP server work, including: - Creating new MCP servers - Modifying existing MCP servers (adding/updating tools, resources, prompts, widgets) - Debugging MCP server issues or errors - Reviewing MCP server code for quality, security, or performance - Answering questions about MCP development or mcp-use patterns - Making ANY changes to server.tool(), server.resource(), server.prompt(), or widgets This skill contains critical architecture decisions, security patterns, and common pitfalls. Always consult the relevant reference files BEFORE implementing MCP features.

React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Use this skill to build and test code changes inside a cudf devcontainer.
Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information from web pages.
Claude Skills meta-skill: extract domain material (docs/APIs/code/specs) into a reusable Skill (SKILL.md + references/scripts/assets), and refactor existing Skills for clarity, activation reliability, and quality gates.
Handle module attribute mapping and mapping history management in Unopim. Use this skill when creating module attribute mapping UI, mapping controller, mapping history, or restricting fields to module structure. Only Attribute Mapping and History tabs are allowed. Covers DB_PREFIX (auto-added by Laravel), Migration/ singular folder, HistoryTrait on models, flat ACL, cURL HTTP client, and JsonResponse controller pattern.
Index of all COSS UI particle examples. Use when implementing UI features to find copy-paste-ready component patterns built on coss primitives. Each particle has a description and a JSON URL for easy installation.
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.

Migrate backend apis from `@atproto/api`, `@atproto/lexicon`, `@atproto/xrpc`, and `@atproto/lex-cli` to `@atproto/lex`. Use this skill whenever the user wants to adopt `@atproto/lex` in a package that currently relies on `@atproto/lex-cli` to perform code generation, replace AtpAgent with Client, migrate generated lexicon code to the new `lex build` output, replace `ids.XxxYyy` with namespace accessors, adopt branded string types, switch from `jsonStringToLex` to `lexParse`, or any refactoring that moves code from the old generated lexicon system to `@atproto/lex`. Also trigger when the user mentions "lexification", "lex SDK", "lex migration", or asks about replacing `@atproto/api` imports in service code.
