Codag on the record

  • Its own site describes it as: "Codag cuts coding-agent costs without changing how developers work. One command attaches it to Claude Code and Codex, and it teaches your agent to read large tool results efficiently." (source)
  • From the Launch YC post "Codag: Compression and control for agent tools": Codag compresses tool results before models read them, lowering costs and improving accuracy without changing how developers work, while providing tool usage analytics. (source)
