README

Kit fixing a failing test suite from the terminal

Kit is a coding agent runtime. It gives the model one tool for writing and running programs.
Kit provides a terminal client, an ACP server, an A2A endpoint, and a subagent orchestrator in one static binary.

Why Kit

Most agent harnesses expose many tools and require one model round trip for each call. Kit exposes one tool: `compose`. The `compose` argument is a short program in [Runlet](https://github.com/danielkov/runlet). In one round trip, the program can read files, run tests, apply edits, retry failed commands, delegate work to subagents, and return structured data.

Fewer model round trips repeat less context and complete more work in each request. In size-matched production tasks, Kit used approximately half the input tokens and active time per hand-written line of Codex CLI or Claude Code ([comparison](#how-it-compares)).
