"""MCP tool definitions for the Code Review Graph server.

Exposes 27 tools:
1. build_or_update_graph  - full or incremental build
2. get_impact_radius      - blast radius from changed files
3. query_graph            - predefined graph queries
4. get_review_context     - focused subgraph + review prompt
5. semantic_search_nodes  - keyword + vector search across nodes
6. list_graph_stats       - aggregate statistics
7. embed_graph            - compute vector embeddings for semantic search
8. get_docs_section       - token-optimized documentation retrieval
9. find_large_functions   - find oversized functions/classes by line count
10. list_flows            - list execution flows sorted by criticality
11. get_flow              - get details of a single execution flow
12. get_affected_flows    - find flows affected by changed files
13. list_communities      - list detected code communities
14. get_community         - get details of a single community
15. get_architecture_overview - architecture overview from community structure
16. detect_changes        - risk-scored change impact analysis for code review
17. refactor_tool         - unified refactoring (rename preview, dead code, suggestions)
18. apply_refactor_tool   - apply a previously previewed refactoring
19. generate_wiki         - generate markdown wiki from community structure
20. get_wiki_page         - retrieve a specific wiki page
21. list_repos            - list registered repositories
22. cross_repo_search     - search across all registered repositories
23. get_hub_nodes         - find most connected nodes (architectural hotspots)
24. get_bridge_nodes      - find architectural chokepoints (betweenness centrality)
25. get_knowledge_gaps    - identify structural weaknesses
26. get_surprising_connections - find unexpected architectural coupling
27. get_suggested_questions - auto-generated review questions from graph analysis
28. traverse_graph        - BFS/DFS traversal from best-matching node
