Interact with local Chrome browser session via Chrome DevTools Protocol. Use when asked to inspect, debug, or interact with a page open in Chrome, take screenshots, read accessibility trees, evaluate JavaScript, click elements, or navigate pages.

React and Next.js performance optimization guidelines from Vercel Engineering. Use when writing, reviewing, or refactoring React/Next.js code for optimal performance. 62 rules across 8 categories covering waterfalls, bundle size, server-side, re-renders, and rendering.

Write mathematics in a long-form, understanding-focused style with detailed proofs and rich exposition. Use when explaining mathematical concepts, writing proofs, tutoring math, creating educational math content, or when the user asks for mathematical explanations. Inspired by Jay Cummings' Real Analysis and Chartrand's Mathematical Proofs.

Build and refactor CLIs for AI agent compatibility. Use when making CLI tools machine-readable with structured JSON output, input hardening, schema introspection, dry-run safety, and MCP surfaces.

Convert game walkthroughs and guides from plain text into structured, interlinked Obsidian markdown pages. Use when the user wants to convert a walkthrough, FAQ, guide, or reference document into Obsidian vault pages. Triggers on mentions of converting walkthroughs, guides, or FAQs to Obsidian, or splitting a large text file into Obsidian pages.

Generate, validate, and fix diagrams from Mermaid markup using mmdc. Use when creating flowcharts, sequence diagrams, class diagrams, converting .mmd files to images/SVG/PDF, or validating and fixing Mermaid diagram syntax.

Automatically fold uncommitted changes into appropriate commits. Use for applying review feedback and maintaining atomic commit history.

Remote control tmux sessions for interactive CLIs (python, gdb, etc.) by sending keystrokes and scraping pane output. Use when debugging applications, running interactive REPLs (Python, gdb, ipdb, psql, mysql, node), automating terminal workflows, or when user mentions tmux, debugging, or interactive shells.

Review and ensure skills maintain high quality standards. Use when creating new skills, updating existing skills, or auditing skill quality. Checks for progressive disclosure, mental model shift, appropriate scope, and documentation clarity.

Invoke deep sequential thinking for complex problem-solving. Use when the user says 'use ultrathink', 'ultrathink', or when tackling problems that require careful step-by-step reasoning, planning, hypothesis generation, or multi-step analysis.

Format git commit messages following Conventional Commits 1.0.0 specification. Use when the user asks to commit changes, create a git commit, or mentions committing code. Ensures consistent, semantic commit messages that support automated changelog generation and semantic versioning.

Manage and rebase chains of dependent Git branches (stacked branches). Use when working with multiple dependent PRs, feature branches that build on each other, or maintaining clean branch hierarchies. Automates rebasing or merging entire branch chains.

Jujutsu (jj) version control system - a Git-compatible VCS with novel features. Use when working with jj repositories, managing stacked commits, needing automatic rebasing with first-class conflict handling, using revsets to select commits, or wanting enhanced Git workflows. Triggers on mentions of 'jj', 'jujutsu', change IDs, or operation log.

Command-line fuzzy finder for interactive filtering. Use when searching files, command history (CTRL-R), creating interactive menus, or integrating with ripgrep, fd, and git. Triggers on fzf, fuzzy finder, ** completion, or CTRL-T/CTRL-R/ALT-C keybindings.

Browser automation with Playwright for Python. Use when testing websites, taking screenshots, filling forms, scraping web content, or automating browser interactions. Triggers on browser, web testing, screenshots, selenium, puppeteer, or playwright.

Terminal workspace and multiplexer for interactive CLI sessions. Use when managing terminal sessions, running interactive REPLs, debugging, automating terminal workflows, or when user mentions zellij, floating panes, or session layouts. Simpler alternative to tmux.

Guide AI-assisted UI generation toward enterprise-grade design. Use when building UIs, creating dashboards, designing SaaS applications, or generating styled frontend code. Enforces 4px grids, typography hierarchies, and consistent depth strategies.
