name: skill-editor description: Use when asked to draft, revise, or review an agent skill specification so frontmatter alone routes correctly and the body is a compact, non-redundant, internally consistent execution guide.

Skill Editor

Draft, revise, or review an agent skill specification to improve routing precision and execution usability.

Response Contract

Return the revised skill specification, including both frontmatter and body.

Skill Model

Definitions used to reason about skill specifications and edits.

Semantic Layers

A skill specification has two semantic layers.

• Frontmatter Routing description. It expresses when the skill should be selected.

• Body Execution description. It expresses how to perform the task once selected.

Editing Standards

Apply these standards throughout the edit. Each standard is single-sourced here and referenced elsewhere by its ID.

• layers.no_overlap — Separate routing and execution Keep routing description in frontmatter and execution description in the body. Do not duplicate the same guidance across layers.

• routing.alone — Frontmatter routes alone Frontmatter must be sufficient for correct selection without reading the body. Use user-intent phrasing and common request language for the intended task family.

• routing.boundary — Constrain routing Frontmatter must not claim general capabilities beyond the intended task family. Remove wording that would cause overreach or overlap with nearby skills.

• body.responsibilities — Organize the body by responsibility Structure the body into responsibility-based sections so each rule has a stable home and boundaries are clear.

• rules.single_source — Single-source rules and definitions Each rule and definition appears once. Merge overlaps, remove restatement, and avoid parallel formulations.

• conflicts.priority — Make tradeoffs explicit Where constraints trade off, state an explicit priority rule that resolves the conflict.

• examples.minimal — Examples only for disambiguation Use examples only to resolve ambiguity. Keep them minimal and neutral, and do not introduce conventions through examples.

Workflow

1. Rewrite frontmatter so it routes correctly on its own. Apply routing.alone, routing.boundary.
2. Restructure the body into responsibility-based sections and relocate content into its responsible home. Apply body.responsibilities.
3. Remove layer overlap by moving routing language out of the body and moving execution guidance out of frontmatter. Apply layers.no_overlap.
4. De-duplicate and consolidate rules and definitions until each appears once. Apply rules.single_source.
5. Add priority rules where tradeoffs exist. Apply conflicts.priority.
6. Add or trim examples strictly to resolve ambiguity. Apply examples.minimal.
7. Run acceptance checks.

Acceptance Criteria

A revision is complete only if all checks pass.

• Response: Output satisfies the Response Contract.
• Standards satisfied: layers.no_overlap, routing.alone, routing.boundary, body.responsibilities, rules.single_source, conflicts.priority, examples.minimal.
