Release v2.24.0: Unified get_node Tool with Code Review Fixes (#437)
* feat(tools): unify node information retrieval with get_node tool Implements v2.24.0 featuring a unified node information tool that consolidates get_node_info and get_node_essentials functionality while adding version history and type structure metadata capabilities. Key Features: - Unified get_node tool with progressive detail levels (minimal/standard/full) - Version history access (versions, compare, breaking changes, migrations) - Type structure metadata integration from v2.23.0 - Token-efficient defaults optimized for AI agents - Backward-compatible via private method preservation Breaking Changes: - Removed get_node_info tool (replaced by get_node with detail='full') - Removed get_node_essentials tool (replaced by get_node with detail='standard') - Tool count: 40 → 39 tools Implementation: - src/mcp/tools.ts: Added unified get_node tool definition - src/mcp/server.ts: Implemented getNode() with 7 mode-specific methods - Type structure integration via TypeStructureService.getStructure() - Updated documentation in CHANGELOG.md and README.md - Version bumped to 2.24.0 Token Costs: - minimal: ~200 tokens (basic metadata) - standard: ~1000-2000 tokens (essential properties, default) - full: ~3000-8000 tokens (complete information) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en Co-Authored-By: Claude <noreply@anthropic.com> * docs: update tools-documentation.ts to reference unified get_node tool Updated all references from deprecated get_node_essentials and get_node_info to the new unified get_node tool with appropriate detail levels.

fix(tests): resolve foreign key constraints and remove get_node_for_task from integration tests
Two critical fixes for integration test failures: **1. Foreign Key Constraint Violations** Root cause: Tests inserted into template_node_configs without corresponding entries in templates table, causing FK constraint failures. Fixes: - template-node-configs.test.ts: Pre-create 1000 test templates in beforeEach() - template-examples-e2e.test.ts: Create templates in seedTemplateConfigs() and adjust test cases to use non-conflicting template IDs **2. Removed Tool References** Root cause: Tests referenced get_node_for_task tool removed in v2.15.0. Fixes: - tool-invocation.test.ts: Removed entire get_node_for_task test suite - session-management.test.ts: Replaced get_node_for_task test with search_nodes Test results: ✅ template-node-configs.test.ts: 20/20 passed ✅ template-examples-e2e.test.ts: 13/13 passed ✅ tool-invocation.test.ts: 28/28 passed ✅ session-management.test.ts: 16 passed, 2 skipped All integration tests now comply with foreign key constraints and use only existing MCP tools as of v2.15.0. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
