Skill Forge

IRON LAW: Every line in a skill must justify its token cost. If it doesn't make the model's output better, more consistent, or more reliable — cut it.

What is a Skill

A skill is an "onboarding guide" for Claude — transforming it from a general-purpose agent into a specialized one with procedural knowledge, domain expertise, and bundled tools.

├── SKILL.md           # Required: workflow + instructions (<500 lines)
├── scripts/           # Optional: deterministic, repeatable operations
├── references/        # Optional: loaded into context on demand
└── assets/            # Optional: used in output, never loaded into context

Default assumption: Claude is already very smart. Only add what Claude doesn't already know. Challenge every paragraph: "Does this justify its token cost?"
