CostWise vs Ripgrep

Ripgrep is an incredibly fast tool for searching strings. However, search is not retrieval. Standard grep engines do not understand function boundaries, scopes, or type implementations, returning huge pages of noisy context.

Feature Breakdown

Feature Capabilities	CostWise	Ripgrep
AST Scope Recognition	Yes	No
Reference Declarations	Yes	No (Fuzzy text matches)
Caller Hierarchy trees	Yes	No
Sub-millisecond Search	Yes (DB index)	Yes (File scanner)

CostWise Advantages

•Saves context by sending only relevant symbol ranges instead of entire matching files.
•Identifies calls even if function names are generic and repeated.

Ripgrep Tradeoffs

•Takes 2 seconds to initialize index database on first startup.

Structural Comparison

CostWise Architecture

Indexes parsed symbols using AST nodes to identify declarations.

Ripgrep Architecture

Linear regex search traversing all raw files on disk.

CostWise maps relationships statically, executing lookup queries in microseconds without scanning disk files during agent steps.

Migration Guide: Moving to CostWise

Switching is quick. CostWise integrates into the same Model Context Protocol slots as Ripgrep.

Setup Instructions

Keep ripgrep as a fallback regex tool.
Add CostWise to your MCP setup to provide semantic symbol retrieval.
