Codeep is an open-source, terminal-native autonomous agent that reads your project structure, plans a sequence of steps, edits files, runs shell commands, and checks its own output against your build and test suite before declaring done. You describe the goal; it handles the steps. The self-verification loop — where it catches a broken typecheck and fixes it without prompting — is the part that separates it from a glorified shell wrapper. The ceiling appears on projects where the agent's context window fills before it has mapped the full dependency graph; community reports suggest large monorepos with deep cross-module dependencies push that limit faster than single-service repos. At that point, teams either scope tasks more tightly or reach for a dedicated sub-agent delegation pattern.
