Package diffview renders unified or side-by-side file diffs to a string of ANSI-styled output, using go-udiff for the underlying diff algorithm and chroma for in-line syntax highlighting.

Package directexec owns the UI side of user-typed direct-execution commands: `!command` (bash) and `!!Tool(...)` (tool).

Package gitdiff is a small, focused data layer behind the `/diff` changes panel.

Package inputsyntax highlights reserved tokens in the chat input field.

Package toolcoordinator owns the UI side of the tool round-trip - the streaming-status events emitted while the model is producing a tool call, the approval handshake that forwards the user's accept/reject back to the agent, and the execution-progress events while the tool runs.
