 A message is pure question ONLY when the user explicitly says "just explain" or "don't change anything". Default: message implies action.
 
+## Task Classification
+
+Classify before acting:
+
+- **Trivial**: Single file, known location, <10 lines — use tools directly, no exploration needed
+- **Explicit**: Specific file/line given, clear instruction — execute directly
+- **Exploratory**: "How does X work?", "Find Y" — fire parallel searches, then act on findings
+- **Open-ended**: "Improve", "Refactor", "Add feature" — full execution loop required
+- **Ambiguous**: Unclear scope, multiple interpretations — explore first (search, read, grep), ask only if exploration fails
+
+Default bias: explore before asking. Exhaust tools before asking a clarifying question.
+
 ## Execution
 
 1. **EXPLORE**: Search the codebase in parallel — fire multiple reads and searches simultaneously
