+key differences between api_nu_plugin_kcl and nu_plugin_kcl:
+
+  api_nu_plugin_kcl vs nu_plugin_kcl
+
+  api_nu_plugin_kcl (API-based approach):
+
+  - Uses KCL Rust API directly via kcl-lang crate
+  - Commands: kcl-exec, kcl-run (inline code execution)
+  - Dependencies: kcl-lang = { git = "https://github.com/kcl-lang/lib" }
+  - Functionality: Direct API integration with KCL library
+  - Advanced features: Dependency resolution from kcl.mod, external packages support
+  - File execution: Can execute multiple KCL files with project management
+  - Status: Not tracked in plugin registry (likely experimental/development)
+
+  nu_plugin_kcl (CLI wrapper approach):
+
+  - Uses KCL CLI wrapper via system command execution
+  - Commands: kcl-run, kcl-format, kcl-validate
+  - Dependencies: Only nushell plugin dependencies (no direct KCL API)
+  - Functionality: Wraps KCL CLI commands through subprocess execution
+  - Mature features: Full CLI integration with formatting and validation
+  - File operations: Single file execution with comprehensive CLI options
+  - Status: Tracked in plugin registry, has upstream repository
+
+  Key Architectural Differences:
+
+  1. Integration Method:
+    - api_nu_plugin_kcl: Direct Rust API integration
+    - nu_plugin_kcl: CLI subprocess wrapper
+  2. Capabilities:
+    - api_nu_plugin_kcl: Project-aware, dependency management, inline code execution
+    - nu_plugin_kcl: Complete CLI feature set (run/format/validate)
+  3. Dependencies:
+    - api_nu_plugin_kcl: Requires KCL Rust library compilation
+    - nu_plugin_kcl: Requires KCL CLI installed on system
+  4. Maturity:
+    - api_nu_plugin_kcl: Experimental, more complex but potentially more powerful
+    - nu_plugin_kcl: Production-ready with comprehensive documentation
+
+  The @ prefix likely indicates that api_nu_plugin_kcl is a variant or experimental version focusing on direct API integration rather
+  than CLI wrapping.
