Draught - A provider-agnostic coding-agent CLI and runtime

Added a simple reusable SKILL system: draught/docs/skills.md at main · ccarvalho-eng/draught · GitHub

I’ve been going through some of your content and source code, and I have a basic question.

For example, the source code and the harness you’ve provided are intended to run AI models on a server, right? If so, why not use OpenCode’s own harness directly on the server?

I’m trying to understand whether building these environments again with Elixir has a specific reason beyond learning and experimentation.

Also, I always find myself trying to compare these things with Jido in my head, but I can’t quite figure out how they map to each other.

Sorry if this is a basic question, and thanks!

There is a relatively long Motivation chapter directly in README.

I can only speak for myself, as a builder of another harness, I find harnesses provided by model providers to be a second-class citizens. Building a harness that would decrease token usage and drastically increase the quality of the outcome does contradict goals of the model providers.

E. g. my harness uses AST for RAG, 100+ MCP tools and whatnot to minimize the necessity of back-and-forth frictions calling the remote. This one aims to do the same, AFAICT.

Thank you, have you created automated loop with your harness? as i remember you are working with DeepSeek? something i want to see your experience

I am not interested in automated loops in the first place. I am positive that without human in the loop an LLM tech cannot produce anything reliable.

I am not “working with DeepSeek” either, I work with a harness, I don’t really give a shot what model is behind (while it’s not OpenAI/Anthropic/Google.) The worse the model, the better harness is.

I meant this to run models offline/local so I can share my obsidian notes, and other personal stuff.

I tried OpenCode. Don’t love their UI, looks like a desktop app inside your terminal. I wanted something simpler and more terminal-like.

I’m trying to understand whether building these environments again with Elixir has a specific reason beyond learning and experimentation.

Probably the reason that survives is to design this following OTP principles since people can use OpenCode, QwenCode, etc

Also, people have their own Neovim configs/setup (why not my own custom AI harness?)… it’s a bit more complex to build a harness but you can always fork my repo and build your own custom version.

About Jido: there’s substantial overlap. Jido would provide established abstractions for supervised agents, pure transitions, effects, events, persistence, plugins, and orchestration. Draught has built narrower equivalents specifically for a coding harness.

This project can certainly be just an experiment, for now, depending on engagement and my spare time and energy to keep evolving it.

Jido already has a harness CLI GitHub - agentjido/jido_code: Terminal-native AI coding assistant built on the Jido agent framework · GitHub , if you’re interested.

Sorry if this is a basic question, and thanks!

No worries. Thanks for checking it out!

I think, loops are dangerous Even with Opus/Fable/Astra etc it doesn’t do what we ask but I am planning something simple enough like cron jobs for recurring no-brainer tasks.

Also, privacy matters now more than ever. “I have nothing to hide” is not a good reason to surrender all your data to private companies. You are doing nothing wrong only for as long as those in power agree on what “wrong” means.

There have been legitimate cases where people were arrested for credible threats they made to AI systems, and rightly so. Even users outside the US have been reported to local authorities after the FBI was alerted. But the deeper concern remains: what happens if the rules change and something considered acceptable today becomes grounds for punishment tomorrow?

Sounds like a conspiracy theory but it’s sadly true

Forgot to also mention GitHub - agentjido/jido_harness: Normalized Elixir protocol for CLI AI coding agents · GitHub

Added “some” builtin skills draught/priv/builtin_skills/catalog at main · ccarvalho-eng/draught · GitHub so this is not so agnostic anymore. Probably an opinionated Elixir harness now
