+- 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.
