What problem does it solve? Documents written for AI agents often fail unpredictably: agents miss referenced material, rush through steps, or drown in bloated context. This Skill provides a systematic reference for writing agent-facing documents (skills, AGENTS.md, CLAUDE.md) so the agent behaves predictably on every run. ## Core Features & Use Cases - Context pointer design: Write descriptions and pointer lines whose wording reliably triggers the agent to reach the right material at the right branch. - Information hierarchy management: Apply progressive disclosure, co-location, and pruning to keep documents legible and free of duplication, no-ops, and stale sediment. - Completion criteria and splitting: Define clear, demanding completion criteria for steps, and split documents by sequence or invocation to prevent premature completion. - Skill mechanics: Choose between model-invoked and user-invoked skills, and build router skills when user-invoked skills multiply. - Use Case: When authoring a new skill or editing an AGENTS.md file, use this Skill to decide what stays inline, what moves behind a pointer, and how to word the description so the agent fires it reliably. ## Quick Start Use the writing-for-agents skill to review and improve the SKILL.md file I am drafting for my new agent skill.
