Systematically debug issues using graph-powered code navigation (code-review-graph MCP). Companion to the `debugger` agent — graph navigation gives breadth, agent gives depth.

Debug Issue (graph-powered)

Use the knowledge graph to systematically trace and debug issues.

Steps

Use semantic_search_nodes to find code related to the issue.
Use query_graph with callers_of and callees_of to trace call chains.
Use get_flow to see full execution paths through suspected areas.
Run detect_changes to check if recent changes caused the issue.
Use get_impact_radius on suspected files to see what else is affected.

Tips

Check both callers and callees to understand the full context.
Look at affected flows to find the entry point that triggers the bug.
Recent changes are the most common source of new issues.

Token Efficiency Rules

ALWAYS start with get_minimal_context(task="<your task>") before any other graph tool.
Use detail_level="minimal" on all calls. Only escalate to "standard" when minimal is insufficient.
Target: complete any review/debug/refactor task in ≤5 tool calls and ≤800 total output tokens.

Cross-link

Pairs with the debugger agent (4-phase systematic debugging). Agent does the thinking (5 Whys, root cause); this skill does the navigation (callers, flows, impact).
