This is a large open-source library of reusable 'skills' — modular instruction packages that give AI coding agents domain expertise they don't have by default. Each skill bundles a SKILL.md (structured instructions, workflows, and decision frameworks), optional Python CLI tools (stdlib-only, no pip installs), and reference docs such as templates and checklists.
Although named for Claude Code, the collection is designed to work across many coding agents — Claude Code, OpenAI Codex, Gemini CLI, OpenClaw, Cursor, Aider, Windsurf, and others — via native formats and conversion scripts that translate the skills into each tool's rules/skills layout. Skills install as Claude Code plugins from a marketplace or by copying folders.
Coverage spans a wide range of domains beyond engineering and DevOps: product, marketing (including SEO/AEO), regulatory and quality management, compliance, project management, finance, research, and C-level advisory personas. Alongside skills it includes agents (task definitions), personas (cross-domain agent identities with curated skill loadouts and communication styles), and a lightweight orchestration protocol for combining them on cross-domain work. A bundled skill-security-auditor scans skills for malicious code before installation.
