Forge kernel surface

Forge is a TDD-first workflow harness. The agent-facing surface is skills + the forge CLI — there are no slash-command files. This umbrella skill is the entry point: it tells you which stage skill to use and which forge verb runs each day-to-day operation. Every skill is a thin guide over a real forge command; the CLI remains the implementation, the skills are the surface.

Stage skills (the TDD ladder)

The default workflow is a configurable ladder of per-stage skills. Use the whole flow when it fits, or invoke an individual stage when the active plan permits a smaller path.
