Skill Writing

Bootstrap a project-local skill with a small observable contract, then symlink it into .claude/skills/ so Claude Code can discover it. Keep invariant workflow guidance in SKILL.md; move deterministic mechanics and conditional detail into scripts and references.

Model Optimization

Optimize every new skill and its content for GPT-5.6 and Claude Fable 5. The summaries below are reminders, not substitutes for the live guides. Read both guides before designing or writing a complex, long-running, multi-tool, or orchestration-heavy skill because their recommendations may evolve.
