GenPark AI Agent Skill - Cross-File Symbol Dependency Graph

Multi-file AST symbol table and dependency graph builder, caller-callee indexing, and change blast radius calculator inspired by Greptile and Cursor codebase indexing.

Features

• Multi-File AST Indexing: Builds complete symbol inventory across modules.
• Call Graph Extraction: Maps caller-to-callee dependencies within and across files.
• Change Blast Radius: Accurately computes upstream cascade impact before modifying functions.

Quickstart

from client import SymbolDependencyGraphClient

graph = SymbolDependencyGraphClient()
graph.index_files({"auth.py": auth_code, "service.py": service_code})
blast = graph.calculate_blast_radius("auth.py::hash_password")
print("Blast Score:", blast["blast_score"])
