Agent Customization

Goal

• Create/update agent assets with minimal token usage and deterministic behavior.

Rules

• RULE: SCOPE_FIRST DO: Default to workspace scope under .github/. AVOID: User-scope output unless explicitly requested.
• RULE: REUSE_EXISTING DO: Search existing instructions/prompts/skills before adding files. AVOID: Duplicate policy text.
• RULE: TIGHT_FRONTMATTER DO: Keep frontmatter to name and description unless required. AVOID: Vague trigger wording.
• RULE: EXPLICIT_CHECKS DO: End with short validation checklist. AVOID: Long narrative explanations.
• RULE: PERF_GATE DO: For performance-sensitive code changes, invoke cpp-performance-and-consistency-optimizer rules. AVOID: Authoring optimization guidance without measurement-first constraints.

Workflow

1. Detect artifact type: instruction / prompt / skill / agent.
2. Search existing files in .github/.
3. Edit in place when possible.
4. Keep guidance concise, imperative, and testable.

Validation

• File in correct folder.
• Frontmatter valid.
• Constraints explicit.
