Motifcode
An independent, open-source terminal coding-agent harness built specifically around the Motif-3 language model's measured behavior, rather than a general harness pointed at a different API endpoint.
Motifcode presents a terminal interface similar to Claude Code, a transcript, a bordered prompt, slash commands and mention syntax, a permission prompt, and a project-local configuration directory, but its tool set, prompt layout, parser and failure handling are built around specific, measured properties of the Motif-3 model rather than assumed to transfer from another model. The author argues that a coding model's practical usability depends mostly on the harness around it: whether its tool calls parse correctly, whether the prompt matches its chat template, whether a malformed turn is repaired instead of ending the session, and whether the tools it is given match the ones it was scored with.
Getting started requires only an account and an API key; running the installer prompts for the key and installs a command-line tool. It is not affiliated with, endorsed by, or maintained by the model's operators.
It is written in TypeScript and released under the Apache-2.0 license.
