fabll (primarily src/faebryk/core/node.py) is the high-level Python API for defining and working with hardware components. It bridges the gap between Python classes and the underlying TypeGraph and instance graph.
Fabll is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/fabll/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when defining new components or traits, working with the Node API, or understanding type registration.
The Fabll Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
mkdir -p ~/.claude/skills/fabll curl -L https://claudskills.com/skills/fabll/SKILL.md \ -o ~/.claude/skills/fabll/SKILL.md
