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.
Simplify overly complex Python code. Use when user asks to simplify, refactor, clean up, make more readable, reduce complexity, improve code quality, find code smells, detect duplicates, or analyze coupling in Python code. Triggers on requests like "simplify this code", "this is too complex", "make this more readable", "refactor this", "clean this up", "find issues", "analyze this codebase", or when reviewing code that exhibits complexity anti-patterns. For Django-specific analysis, use the django-simplifier skill instead.
Portable tmux-based workflow to drive one or multiple long-running Codex CLI “workers” from another process (e.g. Claude CLI) by (1) starting/reusing a tmux session running `codex`, (2) injecting prompts into the Codex pane via `tmux send-keys`/buffer paste, and (3) polling the worker’s Codex JSONL session logs to extract the next assistant reply. Each worker runs with an isolated `CODEX_HOME` (default `~/.codex-workers/<worker_id>`) to prevent log cross-talk when multiple Codex workers run concurrently. Use when you need to submit/wait/read Codex replies in tmux, manage multiple Codex workers, or troubleshoot the tmux worker and log binding.
Documents memory limits and stdlib constraints for PicoRuby on ESP32. Use this when writing code that will run on ESP32 hardware or designing features for PicoRuby applications.
Transform requirements into well-structured User Stories using "As a [user], I want [goal], So that [benefit]" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to "write user story", "create story", "add story" - User mentions "user story", "backlog item", "story" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature request into actionable story with acceptance criteria Output: ALWAYS write story files to docs/reference/pm/stories/{story-name}.md
Scaffolds a new Python tool utility in 'src/tools/' for agents to call. Tools are utility functions (web scraping, PDF parsing, database queries) that agents use. Use when creating utilities that agents depend on.
Use when working with ReLie in REDUCE (including inside Docker) to compute Lie group symmetries of differential equations, handle conditional/contact/variational/approximate symmetries or equivalence transformations, or interpret ReLie outputs and Lie algebra utilities.
Initialize a Dataverse workspace on a new machine or new repo. USE WHEN: ".env is missing", "setting up on a new machine", "starting a new project", "initialize workspace", "new repo", "first time setup", "configure MCP server", "MCP not connected", "load demo data", "sample data", "create a new environment", "select environment", "which environment". DO NOT USE WHEN: installing tools (use dataverse-setup).
Generate new MCP tools for GitLab operations following the project's standardized pattern. Creates complete TypeScript files with imports, registration functions, Zod schemas, error handling, and format options. Supports simple CRUD operations, complex multi-action tools, and advanced patterns like discussion management. Use when "create mcp tool", "generate gitlab tool", "new tool for", "add tool to gitlab", or building new GitLab integration features.
This skill should be used when the user asks to "test for insecure direct object references," "find IDOR vulnerabilities," "exploit broken access control," "enumerate user IDs or object references," or "bypass authorization to access other users' data." It provides comprehensive guidance for detecting, exploiting, and remediating IDOR vulnerabilities in web applications.
Format blog content into properly structured markdown files for Next.js portfolio blog. Use when user wants to: (1) Format raw blog content into markdown with frontmatter, (2) Create new blog posts from topics or titles, (3) Generate blog post files with proper metadata (title, excerpt, date, author) and save to _posts/ directory. Automatically generates excerpts, converts titles to kebab-case filenames, and ensures proper frontmatter format.
Minimal skill
Comprehensive validation for Project Conductor using deep research for best practices. Use when user mentions "validate", "check quality", "review code", "test coverage", or before deployment.
Coordinate multiple agents working simultaneously. Use when splitting tasks across agents or when avoiding overlapping diffs with shared files.
When working with Streamlit web apps, data dashboards, ML/AI app UIs, interactive Python visualizations, or building data science applications with Python
Create comprehensive Product Requirements Documents (PRD) that define what to build and why, focusing on goals, scope, user stories, and success criteria without implementation details. Use this skill when: - User asks to "write a PRD", "create PRD", "write requirements document" - User mentions "requirements document", "product requirements", "product spec" - Running /pm.plan command to create version planning document - Starting a new product, major feature, or initiative that needs formal requirements - Need to document goals, scope, user stories, functional requirements, and success criteria Output: ALWAYS write PRD files to docs/reference/pm/versions/{version-name}.md
Resolve requirement ambiguities through STRUCTURED questioning: one question at a time, with recommended options and reasoning. UNIQUE VALUE: Prevents overwhelming users with multiple questions. Provides expert recommendations for each decision. Use this skill when: - Running /pm.clarify command - User says "unclear", "not sure what this means", "confused about" - User asks "what does X mean?", "how should X work?", "can you clarify?" - Requirements have conflicting or inconsistent details - Stories are missing acceptance criteria or have gaps - Need to fill information gaps BEFORE development can proceed Process: Ask ONE question at a time (max 5 per session), provide recommended option with reasoning. DO NOT ask multiple questions at once - this overwhelms users.
Generate reports from brief.json on demand — without running a build. Four report types for different audiences: brief (design state), build (status + deviations), customer (simplified, zero jargon), deployment (checklists + env mapping).
