Lessloc
Lessloc is an open-source utility that keeps AI coding agents to the least code needed to finish the job.
Lessloc is an open-source tool designed to keep AI coding agents focused on generating the minimal amount of code required to complete a task successfully. It works with agents like Claude Code, Codex, GitHub Copilot, Gemini CLI, Cursor, and OpenCode. By ensuring the agent reuses existing project components instead of rewriting them, lessloc reduces code volume by up to 36 percent and lowers token costs by up to 26 percent. It prevents placeholders, stray backup files, and commented-out code from entering the project. Additionally, it verifies that tests pass before the agent finishes its work. The software runs locally on your machine without requiring an account.
