-## TASKS
+## TASKS (in order — each step feeds the OUTPUT section named)
 
-- Identify relevant parts of the codebase
+1. **Locate** — find the relevant parts of the codebase (Glob/Grep from the target) → file list
-- Understand current behavior
+2. **Understand** — read them; describe current behavior as-is → CONTEXT, KEY COMPONENTS
-- List dependencies
+3. **Map dependencies** — imports, call sites, data flow in/out → KEY COMPONENTS roles
-- Highlight constraints
+4. **Constrain** — invariants, contracts, conventions the code obeys → CONSTRAINTS
-- Detect risks
+5. **Assess** — risks with probability, then ambiguities → RISKS, OPEN QUESTIONS
-- Identify ambiguities
