Authoring

It walks through four distinct paths: drafting new content from scratch, integrating external skills into your project, filling in scaffolded stubs, or improving existing files. The focus is on making skills discoverable and followable by agents, which means tight descriptions under 250 characters, front-loaded critical instructions in the first 5,000 tokens, and matching your project's existing conventions. It enforces the discipline that skills are the source of truth, not documentation. Use this when you're building out a skill bundle and need to maintain consistency across multiple skill files while keeping token budgets reasonable.
