+# Cross-Layer Check
+
+Check if your changes considered all dimensions. Most bugs come from "didn't think of it", not lack of technical skill.
+
+> **Note**: This is a **post-implementation** safety net. Ideally, read the [Pre-Implementation Checklist](.trellis/spec/guides/pre-implementation-checklist.md) **before** writing code.

+
+## Execution Steps
+
+### 1. Identify Change Scope
+
+```bash
+git status
+git diff --name-only
+```
+
+### 2. Select Applicable Check Dimensions
+
+Based on your change type, execute relevant checks below:
+
+---
+
+## Dimension A: Cross-Layer Data Flow (Required when 3+ layers)
+
+**Trigger**: Changes involve 3 or more layers
+
+| Layer | Common Locations |
+|-------|------------------|
+| API/Routes | `routes/`, `api/`, `handlers/`, `controllers/` |
+| Service/Business Logic | `services/`, `lib/`, `core/`, `domain/` |
+| Database/Storage | `db/`, `models/`, `repositories/`, `schema/` |
+| UI/Presentation | `components/`, `views/`, `templates/`, `pages/` |
+| Utility | `utils/`, `helpers/`, `common/` |
+
+**Checklist**:
+- [ ] Read flow: Database -> Service -> API -> UI
+- [ ] Write flow: UI -> API -> Service -> Database
+- [ ] Types/schemas correctly passed between layers?
+- [ ] Errors properly propagated to caller?
+- [ ] Loading/pending states handled at each layer?
+
+**Detailed Guide**: `.trellis/spec/guides/cross-layer-thinking-guide.md`
+
+---
+
+## Dimension B: Code Reuse (Required when modifying constants/config)
+
+**Trigger**: 
+- Modifying UI constants (label, icon, color)
+- Modifying any hardcoded value
+- Seeing similar code in multiple places
+- Creating a new utility/helper function
+- Just finished batch modifications across files
+
+**Checklist**:
+- [ ] Search first: How many places define this value?
+  ```bash
+  # Search in source files (adjust extensions for your project)
+  grep -r "value-to-change" src/
+  ```
+- [ ] If 2+ places define same value -> Should extract to shared constant
+- [ ] After modification, all usage sites updated?
+- [ ] If creating utility: Does similar utility already exist?
+
+**Detailed Guide**: `.trellis/spec/guides/code-reuse-thinking-guide.md`
+
+---
+
+## Dimension B2: New Utility Functions
+
+**Trigger**: About to create a new utility/helper function
+
+**Checklist**:
+- [ ] Search for existing similar utilities first
+  ```bash
+  grep -r "functionNamePattern" src/
+  ```
+- [ ] If similar exists, can you extend it instead?
+- [ ] If creating new, is it in the right location (shared vs domain-specific)?
+
+---
+
+## Dimension B3: After Batch Modifications
+
+**Trigger**: Just modified similar patterns in multiple files
+
+**Checklist**:
+- [ ] Did you check ALL files with similar patterns?
+  ```bash
+  grep -r "patternYouChanged" src/
+  ```
+- [ ] Any files missed that should also be updated?
+- [ ] Should this pattern be abstracted to prevent future duplication?
+
+---
+
+## Dimension C: Import/Dependency Paths (Required when creating new files)
+
+**Trigger**: Creating new source files
+
+**Checklist**:
+- [ ] Using correct import paths (relative vs absolute)?
+- [ ] No circular dependencies?
+- [ ] Consistent with project's module organization?
+
+---
+
+## Dimension D: Same-Layer Consistency
+
+**Trigger**: 
+- Modifying display logic or formatting
+- Same domain concept used in multiple places
+
+**Checklist**:
+- [ ] Search for other places using same concept
+  ```bash
+  grep -r "ConceptName" src/
+  ```
+- [ ] Are these usages consistent?
+- [ ] Should they share configuration/constants?
+
+---
+
+## Common Issues Quick Reference
+
+| Issue | Root Cause | Prevention |
+|-------|------------|------------|
+| Changed one place, missed others | Didn't search impact scope | `grep` before changing |
+| Data lost at some layer | Didn't check data flow | Trace data source to destination |
+| Type/schema mismatch | Cross-layer types inconsistent | Use shared type definitions |
+| UI/output inconsistent | Same concept in multiple places | Extract shared constants |
+| Similar utility exists | Didn't search first | Search before creating |
+| Batch fix incomplete | Didn't verify all occurrences | grep after fixing |
