Tools that ship.Built for builders.

The complete 15-chapter playbook for a Claude Code skill library that compounds — from your first skill to a full worked example, with anti-patterns, a starter set, and copy-paste templates.

• 15 chapters — foundations to operating a library
• A full skill built end to end, annotated
• The nine skill types and when to build each
• Anti-patterns catalog + a first-week starter set

Ten AI-powered command-line tools to build with Bun and Claude — a stdin-piping primitive, git-aware commits and code review, scaffolding, regex, and a resumable chat REPL.

• The anatomy of a Bun + Claude CLI
• ask and pipe: the two composable primitives
• Git-aware commits, code review, and changelogs
• Scaffold files, generate tested regex, rename symbols

A free one-page reference for the compound engineering workflow in Claude Code — the loop, every command, the common flows, and the rules.

• The human-vs-autonomous loop at a glance
• Every /ce command, grouped by phase
• Copy-paste flows for features, bug fixes, and autopilot
• P1/P2/P3 review priorities and the core rules
