Validate domain boundaries -- detect cross-context import violations and aggregate invariant issues

General

What this skill does

Validate domain boundary integrity across all bounded contexts.

## Steps

1. **Discover contexts**: Scan `src/*/domain/` to find all bounded contexts.

2. **Check cross-boundary violations**:
   - For each context, scan all `.ts` files for import statements
   - Flag any import that reaches into another context's `domain/` directory directly
   - Allowed: importing from another context's public `index.ts` (application layer)
   - Violation: importing from `src/<other-context>/domain/entities/...` directly

   ```bash
   # Find cross-boundary imports
   for ctx in $(find src -maxdepth 2 -name "domain" -type d | sed 's|src/||;s|/domain||'); do
     grep -rn "from ['\"].*src/" "src/$ctx/" --include="*.ts" | grep -v "src/$ctx/" || true
   done
   ```

3. **Check aggregate invariant enforcement**:
   - Scan aggregate root entities for public setters that bypass validation
   - Flag mutable public properties without invariant checks
   - Verify that child entities are not directly accessible (must go through aggregate root)

4. **Check event naming conventions**:
   - Domain events should be past-tense named (e.g., `OrderCreated`, not `CreateOrder`)
   - Events should be immutable (no public setters)
   - Events should carry the aggregate ID

5. **Check repository patterns**:
   - Repository interfaces should exist in `domain/repositories/`, not `infrastructure/`
   - Repository implementations should exist in `infrastructure/`, not `domain/`
   - Each aggregate root should have exactly one repository

6. **Report findings**:
   - Output a table of violations with file path, line number, violation type, and suggestion
   - Categorize as: `BOUNDARY`, `INVARIANT`, `EVENT`, `REPOSITORY`
   - Exit with summary: total violations, by category, severity

7. **Store results**:
   ```bash
   npx @claude-flow/cli@latest memory store --key "ddd-validation-TIMESTAMP" --value "RESULTS_SUMMARY" --namespace tasks
   npx @claude-flow/cli@latest hooks post-task --task-id "ddd-validate" --success true --store-results true
   ```
