Write or fix a prompt for a reasoning model (Gemini Pro, GPT-4o, Claude Sonnet) so it holds context across a multi-step task. Use for any request to draft, structure or debug such a prompt. Not for fast models (use engineer-prompts-for-instant).

Build AI-IDE plugin MCP elements - stdio JSON-RPC servers, tool schemas, host wiring for Claude Code/Codex, event-name mapping and validation. Use when building or adding an MCP server to a plugin. Not for plugin manifests or packaging.

Build AI-IDE plugin hook elements - shared policies plus Claude Code/Codex/OpenCode/Cursor adapters for lifecycle events, blocking, audit, and context injection. Use when adding or configuring plugin hooks.

Guide for creating effective Subagents (custom agent definitions). Use when users want to create a new subagent, set up task-specific agents, configure code reviewers, debuggers, or domain-specific assistants. Works across IDEs (Cursor, OpenCode).

Use when the user wants to rename, extract, split, move, or restructure code safely. Examples: "Rename this function", "Extract this into a module", "Refactor this class", "Move this to a separate file"

Load when the request depends on what is already on this instance rather than on what the user just typed: a short or ambiguous opener ("fix it", "carry on", "what should I look at"), a reference to earlier work in a new conversation, or any question about what has recently run or broken.

Lookup procedure for Simplified Custom Auth recipe fields — sources the auth template, the key-issuing docsUrl and an auth-rejecting testUrl from the provider's real documentation instead of memory. Load before composing credentialHints for a service without a dedicated credential type (the post-build-flow setup step), or when asked to fix a recipe whose template, key page or test endpoint is wrong.

DEPRECATED: This skill has been replaced by `mcp-app-builder`. Check if `mcp-app-builder` is available in the skills folder. If not, install it: `npx skills install mcp-use/mcp-use --skill mcp-app-builder` Use `mcp-app-builder` instead of this skill. 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.

Pull metrics from analytics dashboards and internal web tools with Firecrawl browser. Use when the user needs dashboard reporting, cross-platform metric summaries, authenticated analytics extraction, date-range reports, or structured metrics from web dashboards.

Use when creating SQLModel database models, CRUD operations, queries with joins, or relationships. NOT when non-database operations, plain SQL, or unrelated data handling. Triggers: "SQLModel", "database model", "CRUD", "create/read/update/delete", "query", "ForeignKey", "relationship".

Add a New Pass Manager (NPM) pass to an LLVM 22 in-tree or out-of-tree project. Covers FunctionPass, ModulePass, LoopPass, and CGSCCPass kinds, registration, pipeline wiring, CMake, and lit testing.

City lifecycle — status, start, stop, init

JSON input and output schemas for all perplexity-cli commands (search, ask, chat). Use when constructing --json payloads or parsing command output programmatically.

Use when creating SQLModel database models, CRUD operations, queries with joins, or relationships. NOT when non-database operations, plain SQL, or unrelated data handling. Triggers: "SQLModel", "database model", "CRUD", "create/read/update/delete", "query", "ForeignKey", "relationship".

Runs the AI Engineer loop on pi — codegraph understand, gather materials, fill prompt templates, review those prompts, then fan out tasks. Use when spawning subagents, building worker prompts from templates, or gating fan-out on prompt review.

Focused pattern for fetching data using URL parameters in Next.js. Covers creating dynamic routes ([id], [slug]) and accessing route parameters in server components to fetch data from APIs. Use when building pages that display individual items (product pages, blog posts, user profiles) based on a URL parameter. Complements nextjs-dynamic-routes-params with a simplified, common-case pattern.

Pattern for client components calling server actions to set cookies in Next.js. Covers the two-file pattern of a client component with user interaction (onClick, form submission) that calls a server action to modify cookies. Use when building features like authentication, preferences, or session management where client-side triggers need to set/modify server-side cookies.

Edit and improve articles by restructuring sections, improving clarity, and tightening prose. Use when user wants to edit, revise, or improve an article draft.

Use when the user wants to turn one or more Entire-tracked sessions, checkpoints, or repeated agent workflows into a reusable agent skill.

Plan phase of RPI methodology. Consumes research artifact or topic and produces compact implementation plan with test specs and Agent Context blocks. Use after research or to start planning a non-trivial feature.
