According to CoinMeta, developer David has open-sourced a research tool jevgrep specifically for finding code related to Coding Agent based on jev. Users only need to ask where the login verification is written, and this tool will use the decision model jev of typesafe to search through the codebase layer by layer, identifying relevant files and code snippets, which are then handed over to Claude Code, Codex, and other Agent for further modification and testing. The latest swe-bench experiments show that both with and without using jevgrep and jevgrep, 8 Python tasks were completed. However, the total cost for gpt-5.6 and SOL was reduced from $7.62 to $5.44, a decrease of about 28.63%.
