Use when authoring or editing shared Copilot resources that should stay lightweight and inexpensive to run.	resources/prompts/**/*.prompt.md,resources/instructions/**/*.instructions.md,resources/agents/**/*.agent.md,resources/skills/**/SKILL.md

• Reuse an existing shared resource before creating a new one.
• Prefer the cheapest sufficient primitive: instruction for durable rules, skill for portable workflows, prompt for thin VS Code entrypoints, hook only for deterministic enforced behavior.
• Keep frontmatter, examples, and repeated policy text short.
• Ask for narrow inputs such as a file, symbol, or command instead of broad workspace scans when possible.
• Bias the resource toward concise outputs unless the task clearly needs depth.
• Say when the resource should not be used if that prevents broad, expensive misuse.
