Skill Diet

Keep agent skills lean and correct. Use before editing an existing skill, such as adding a lesson; when a code change touches names or behavior a skill describes; and to put a skill on a full diet when it is large, loads detail most tasks never use, or has drifted from the tool it teaches.

# Skill Diet

## Levels

Put each fact on the lowest level that still reaches the agent before it needs it.

| Level | Holds | Loaded |
| --- | --- | --- |
| `description` | one trigger per case | every session |
| `SKILL.md` | what every task needs | when the skill is used |
| `references/` | what only some tasks need, behind a link that says when to read it | when that case comes up |

A skill that teaches a tool has two more levels: the tool's help, then its replies and errors. Exact names, fields and values live there, not in the skill. A check on the skill's output (linter, tests, renderer) can replace a rule, unless one miss costs a slow cycle.

## Editing a skill

Stop at the first step that handles the change.

1. **Fix it below the skill.** A mechanical mistake gets a clearer error, a check, or a test in the tool. Prose is for judgment calls.
2. **Check the model needs it.** If a fresh session does the right thing without the line, add nothing.
3. **Edit, don't append.** Change the line that already covers the idea. Each meaning lives in one place across `SKILL.md`, references, and the tool's docs.
4. **Pick its level.**
5. **Write the rule, not the story.** One positive rule under a short name; the incident goes in the commit message.
