# Skill Authoring Use this user-invoked skill to create a new Agent Skill or improve an existing one. Optimize for predictable behavior, narrow responsibility, and low context cost. ## Workflow 1. Inspect the existing skill, supporting files, nearby skills, and repository guidance. Preserve useful behavior and identify stale references before editing. 2. Define the skill contract: - **Objective:** the single outcome the skill owns. - **Prerequisites:** evidence, files, tools, or state required to begin. - **Invocation:** who should trigger it and under what narrow conditions. - **Workflow:** ordered actions that materially change agent behavior. - **Safety boundaries:** destructive, publishing, Git, data, and scope limits specific to the skill. - **Completion criteria:** observable conditions for a finished run. - **Validation:** structural and behavioral checks for the skill itself. 3. Choose invocation policy: - **Model-invoked:** omit `disable-model-invocation`; write a narrow description containing positive trigger conditions and explicit non-triggers when accidental activation is plausible. - **User-invoked:** set `disable-model-invocation: true`; write a concise human-facing description. 4. Put the common workflow in `SKILL.md`. Move branch-specific reference material to clearly named supporting files only when that reduces the context needed for ordinary runs. 5. Remove no-op instructions, promotional prose, stale assumptions, and generic
