+# Codebase References
+
+**Purpose**: Link context files to actual code implementation
+
+**Last Updated**: 2026-01-27
+
+---
+
+## Core Principle
+
+<rule id="link_to_code" enforcement="critical">
+  ALL context files SHOULD include `📂 Codebase References` section linking to relevant code.
+  Use sections that apply to your context type (not all files need all sections).
+</rule>
+
+**Why**: Agents need to find actual implementation, not just read about it.
+
+---
+
+## Section Types (Use What's Relevant)
+
+### Business Domain Context
+```markdown
+**Business Logic**: (MOST IMPORTANT for business domains)
+- `src/orders/rules/validation-rules.ts` - Order validation business rules
+
+**Implementation**:
+- `src/orders/order-processor.ts` - Main order processing logic
+
+**Models/Types**:
+- `src/orders/models/order.model.ts` - Order data model
+
+**Tests**:
+- `src/orders/__tests__/processor.test.ts` - Order processing tests
+
+**Configuration**:
+- `config/orders.config.ts` - Order processing config
+```
+
+### Technical/Code Context
+```markdown
+**Implementation**: (MOST IMPORTANT for technical contexts)
+- `src/auth/jwt-handler.ts` - JWT authentication implementation
+
+**Examples**:
+- `src/auth/examples/jwt-example.ts` - Working JWT example
+
+**Types**:
+- `src/auth/types/jwt-payload.ts` - JWT payload types
+
+**Tests**:
+- `src/auth/__tests__/jwt.test.ts` - JWT tests
+```
+
+### Standards/Quality Context
+```markdown
+**Validation/Enforcement**: (MOST IMPORTANT for standards)
+- `scripts/validate-code-quality.ts` - Code quality validator
+- `eslint.config.js` - ESLint rules
+
+**Examples**:
+- `examples/good-code.ts` - Good code example
+- `examples/bad-code.ts` - Anti-pattern example
+
+**Tests**:
+- `tests/code-quality.test.ts` - Quality validation tests
+```
+
+### Operational Context
+```markdown
+**Scripts/Tools**: (MOST IMPORTANT for operations)
+- `scripts/deploy.sh` - Deployment script
+- `scripts/monitor.ts` - Monitoring setup
+
+**Configuration**:
+- `config/deployment.config.ts` - Deployment configuration
+- `.github/workflows/deploy.yml` - CI/CD workflow
+```
+
+---
+
+## Rules
+
+<rule id="path_format" enforcement="strict">
+  1. Use project-relative paths (src/..., not /Users/...)
+  2. Use forward slashes (/)
+  3. Include file extension (.ts, .js, .sh)
+  4. Brief description (3-10 words) for each file
+  5. Verify files exist (warn if not found)
+  6. Use relevant sections only (not all files need all sections)
+</rule>
+
+---
+
+## Examples
+
+**Business Context**:
+```markdown
+## 📂 Codebase References
+
+**Business Logic**:
+- `src/payments/rules/validation-rules.ts` - Card validation rules
+- `src/payments/rules/fraud-detection.ts` - Fraud detection logic
+
+**Implementation**:
+- `src/payments/payment-processor.ts` - Main payment processing
+
+**Tests**:
+- `src/payments/__tests__/processor.test.ts` - Payment tests
+```
+
+**Technical Context**:
+```markdown
+## 📂 Codebase References
+
+**Implementation**:
+- `src/auth/jwt-handler.ts` - JWT authentication
+
+**Examples**:
+- `examples/jwt-auth.ts` - Working example
+
+**Tests**:
+- `src/auth/__tests__/jwt.test.ts` - JWT tests
+```
+
+---
+
+## Validation
+
+- [ ] Has "📂 Codebase References" section?
+- [ ] Most important section for context type included?
+- [ ] Paths are project-relative?
+- [ ] Paths include extensions?
+- [ ] Each path has 3-10 word description?
