IMPORTANT: This project has a knowledge graph. ALWAYS use the code-review-graph MCP tools BEFORE using Grep/Glob/Read to explore the codebase. The graph is faster, cheaper (fewer tokens), and gives you structural context (callers, dependents, test coverage) that file scanning cannot.
- Exploring code:
semantic_search_nodesorquery_graphinstead of Grep - Understanding impact:
get_impact_radiusinstead of manually tracing imports - Code review:
detect_changes+get_review_contextinstead of reading entire files - Finding relationships:
query_graphwith callers_of/callees_of/imports_of/tests_for - Architecture questions:
get_architecture_overview+list_communities
Fall back to Grep/Glob/Read only when the graph doesn't cover what you need.
| Tool | Use when |
|---|---|
detect_changes |
Reviewing code changes — gives risk-scored analysis |
get_review_context |
Need source snippets for review — token-efficient |
get_impact_radius |
Understanding blast radius of a change |
get_affected_flows |
Finding which execution paths are impacted |
query_graph |
Tracing callers, callees, imports, tests, dependencies |
semantic_search_nodes |
Finding functions/classes by name or keyword |
get_architecture_overview |
Understanding high-level codebase structure |
refactor_tool |
Planning renames, finding dead code |
- The graph auto-updates on file changes (via hooks).
- Use
detect_changesfor code review. - Use
get_affected_flowsto understand impact. - Use
query_graphpattern="tests_for" to check coverage.
