Supported agents
Supports three query directions: incoming calls (who calls this), outgoing calls (what this calls), and bidirectional analysis
Configurable traversal depth (default 3 levels) to control graph scope and complexity
Generates ASCII tree visualizations with entry points, leaf functions, and hot path analysis
Includes complexity insights and potential issues flagging (high fan-out, multiple callers)

Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionrust-call-graphExecute the skills CLI command in your project's root directory to begin installation:
epx add zhanghandong/rust-skills --skill rust-call-graphFetches rust-call-graph from zhanghandong/rust-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
.cursor/skills/rust-call-graph
Restart Cursor to activate rust-call-graph. Access via /rust-call-graphin your agent's command palette.
