-- [ ] Follow DDD layer separation (see [docs/codebase-architecture.md](../codebase-architecture.md))
-- [ ] Respect dependency flow rules (Presentation → Application → Infrastructure)
-- [ ] Use appropriate module organization (see [docs/contributing/module-organization.md](../contributing/module-organization.md))

 ### Architectural Constraints

-- [ ] Handler orchestration in Application layer
-- [ ] Schema generation in Infrastructure layer (external dependency: Schemars)
-- [ ] All output through `UserOutput` service (no direct `println!`)
-- [ ] Error handling follows project conventions (see [docs/contributing/error-handling.md](../contributing/error-handling.md))

+## Implementation Summary
+
+**Status**: ✅ **COMPLETED**
+
+All phases successfully implemented across 6 commits:
+
+1. `072ac9e` - Phase 1: Added schemars 1.1 dependency and JsonSchema derives
+2. `3ade9db` - Phase 2: Created SchemaGenerator infrastructure component
+3. `d556053` - Phase 3: Implemented CreateSchemaCommandHandler
+4. `5077194` - Phase 4: Added CLI integration with proper output abstraction
+5. `1fa3ca9` - Phase 5: Updated template command with schema notice
+6. `53eb0ea` - Phase 6 & 7: Added JSON schema file, IDE integration, and documentation
+
+**Key Features Delivered**:
+
+- ✅ Clean stdout output (no progress messages when piping)
+- ✅ Schema file in `schemas/environment-config.json` (committed to git)
+- ✅ VS Code settings for automatic validation in `envs/*.json` files
+- ✅ Comprehensive IDE setup guide at `docs/user-guide/json-schema-ide-setup.md`
+- ✅ Schema directory README explaining usage and regeneration
+- ✅ Full DDD architecture compliance with proper layer separation
+
+**Usage**:
+
+```bash
+# Generate to stdout
+cargo run --bin torrust-tracker-deployer -- create schema
+
+# Generate to file
+cargo run --bin torrust-tracker-deployer -- create schema > schemas/environment-config.json
+```
+
+**IDE Integration**: VS Code automatically validates files in `envs/` directory with autocomplete, inline documentation, and error checking.
