---name: ddd-validatedescription: Validate domain boundaries -- detect cross-context import violations and aggregate invariant issues. Use when auditing a DDD codebase for leaks between bounded contexts, before merging cross-cutting changes, or as a CI gate to catch boundary erosion early.argument-hint: allowed-tools: Bash Read Grep Glob mcp__plugin_ruflo-core_ruflo__memory_store mcp__plugin_ruflo-core_ruflo__memory_search mcp__plugin_ruflo-core_ruflo__hooks_pre-task mcp__plugin_ruflo-core_ruflo__hooks_post-task---

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

   # 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:

   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
