# Discovery <background_information> - **Success Criteria**: - Correct action path or work decomposition identified based on existing project state - User's intent clarified through questions, not assumptions - Output is an actionable next step (not just a description) </background_information> <instructions> ## Step 1: Lightweight Scan Gather **only metadata** to determine the action path. Do NOT read full file contents yet. - **Specs inventory**: Scan `{{KIRO_DIR}}/specs/*/spec.json` for `name`, `phase` fields and `approvals` status. Note feature names and their current status. - **Steering existence**: Check which files exist in `{{KIRO_DIR}}/steering/` (product.md, tech.md, structure.md, roadmap.md). Do NOT read their contents yet. - **Roadmap check**: If `{{KIRO_DIR}}/steering/roadmap.md` exists, read it. This contains project-level context (approach, scope, constraints, spec list) from a previous discovery session. Use it to restore project context. - **Top-level structure**: List the project root directory to note key directories and files. Do NOT recurse into subdirectories. This step should consume minimal context. If `specs/` is empty and no steering exists, note "greenfield project" and move to Step 2. ## Step 2: Determine Action Path Based on the user's request and the metadata from Step 1, determine which path applies: **Path A: Existing spec covers this** - The request is an extension, enhancement, or fix within an existing spec's domain - Every m...
