newt-coder

Coder plugin for newt-agent: whole-file emit + server-side diff normalization.

The default newt worker path asks the model to emit a unified diff with no file contents in context — local coder models reliably invent plausible-but-wrong context lines, so the patch fails to apply (failure mode T0b). newt-coder is the opinionated fix: it scans the workspace for files the task mentions, injects them verbatim into the prompt, and asks the model to emit each updated file in full. normalize_emission parses the reply, the changes are written to the workspace, and the caller captures a real diff via git diff.

Activated via NEWT_CODER=1 or the per-session ACP param { "coder": true }; the legacy path remains the default.

Part of Newt-Agent, a small, fast, local-first agentic coder.
