Analyze AI coding agent usage, cost, efficiency, and burn rate — Claude Code (ccusage), Pi/pi-agent (ccusage-pi), or Codex CLI (ccusage-codex). Use when user says "usage", "cost", "spending", "tokens", "analyze usage", "how much did I spend", "usage report", "budget", "burn rate", "efficiency", "cache hits", "ccusage", "ccw", "ccp". NOT for general shell scripting, non-AI-agent cost analysis, or cloud infrastructure billing (use using-cloud-cli).

Use when planning, executing, checkpointing, finishing, or inspecting lightweight spec-driven work. Runs one task at a time using `.spec/` markdown files and the bundled `specctl` helper. NOT for broad product discovery beyond a short requirement interview. NOT for generic implementation planning that does not read or write `.spec/` files.
development
Simple web development with HTML, CSS, JS, and HTMX. Use when working with .html, .css, or .htmx files, web templates, stylesheets, or vanilla JS scripts. NOT for React/Vue/Angular (use writing-typescript) or Node.js backends.

Emphasizes strict typing, boundary validation, composition, fast feedback, behavior tests, and project-configured tooling. NOT for Go, Python, Rust, plain HTML/CSS/JS, or server-rendered templates (use writing-web).

Idiomatic shell development for POSIX sh, Bash, Zsh, Fish, hooks, CI shell steps, and scriptable CLI glue.
