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-6 Astra and Claude Fable 5.1. 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.

• GPT-6 Astra prompting guidance: Complete authorized work under stated assumptions; make user-instruction precedence over skills explicit; specify writing and delegation preferences; and keep verification proportional to the change.
• Claude Fable 5.1 prompting guidance: Calibrate effort with evals; request progress updates; batch independent tool calls; preserve decisions across compaction; verify changing facts; and finish the requested scope with targeted edits and proportionate tests.
