v0.1.0

Distil v0.1.0

Token-efficient code analysis for LLMs — extract structure instead of dumping text.

Highlights

• 5 analysis layers for TypeScript/JavaScript:
  • L1: AST extraction (functions, classes, imports, signatures)
  • L2: Cross-file call graph with impact analysis
  • L3: Control flow graph with cyclomatic complexity
  • L4: Data flow graph with def-use chains
  • L5: Program dependence graph with backward/forward slicing
• MCP server for editor and agent integration (Claude Code, Cursor, etc.)
• CLI with 8 commands: tree, extract, calls, impact, cfg, dfg, slice, mcp
• ~95% token reduction compared to raw source code
