Coordinate with other AI agents running in tmux panes. Use this skill when you need to delegate tasks, request reviews, or collaborate with agents like Codex, Gemini, or other Claude instances.

Use when designing API endpoints. Enforces layered architecture, separation of concerns, and type safety. Supports Express.js and similar frameworks.

Architects token systems with primitive, semantic, and component layers. Use when structuring tokens from scratch, adding multi-theme support, setting up token aliasing, or organizing token hierarchies.

Expert guidance for using the GitHub CLI (gh) to manage GitHub issues, pull requests, Actions workflows, repositories, and other GitHub operations from the command line. Use this skill when the user needs to interact with GitHub resources or perform GitHub workflows.

Use when debugging NavigationStack issues (not responding, unexpected pops, crashes), build failures (SPM resolution, "No such module", hanging builds), or memory problems (retain cycles, leaks, deinit not called). Systematic diagnostic workflows for iOS/macOS.

Scaffolds new Buck2 projects with proper BUILD/PACKAGE files, SPDX headers, and depot shims. Use when creating new Rust binaries/libraries, Deno tools, or C++ projects in the monorepo. Ensures consistent structure and metadata from the start.
