Skill cristianorj22/arthus-harness/plugins/mcp-code-review-graph/claude/skills/explore-codebase

Navigate and understand codebase structure using the code-review-graph knowledge graph (MCP). Use when needing breadth — module map, architecture, who-calls-whom — without reading 50 files.From its SKILL.md

Explore Codebase

Use the code-review-graph MCP tools to explore and understand the codebase.

Steps

Run list_graph_stats to see overall codebase metrics.
Run get_architecture_overview for high-level community structure.
Use list_communities to find major modules, then get_community for details.
Use semantic_search_nodes to find specific functions or classes.
Use query_graph with patterns like callers_of, callees_of, imports_of to trace relationships.
Use list_flows and get_flow to understand execution paths.

Tips

Start broad (stats, architecture) then narrow down to specific areas.
Use children_of on a file to see all its functions and classes.
Use find_large_functions to identify complex code.

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.

When NOT to use

For surgical edits where you already know the file path → use Read + Edit directly.
If code-review-graph MCP isn't connected (verify with the harness-doctor skill or code-review-graph status) → fall back to Glob + Grep.
