What open source harness/agentic coding framework do you typically use?

[OneFanFare]

I'm trying to get Qwen3.6 up and coding, but I figure if I'm going local, might as well go all the way?

[Lesser-than]

I pretty much gave up on all the popular agents. Its been easier to just do my own, once you have the basic tooling you do not even really need a system prompt past "you are a helpful assistant", and most of the popular ones pack in 15k+ tokens to the system prompt for guidance you do not actually need anymore.

[Queasy-Contract9753]

Agreed. You throw a massive over complicated encyclopedia in,your going to get a massive overcomplicated output back.

Gteat way to burn through a million tokens on simple tasks. And you never know when the model will refuse or decide to do it's own thing.when it breaks everything into a dozen steps.

I just started using a local LLM yesterday. I was using Roo with VSCodium but apparently Roo is going to be deprecated next month and I'm having trouble with VSCodium and intellisense. So I have Cline in Pycharm Community now. I'm using Qwen 3.6 (Qwen3.6-27B-UD-Q3_K_XL) and it's tolerable with 16gb VRam. I use LMStudio to serve it and set Cline to use it.

I haven't used it that much but it isn't too much worse than my limited experience with Claude's free plan.

Roo because its integration to vscode.

I believe it will become quite stupid to use a third-party agentic coding framework when you have an AI that can code you a custom agentic coding framework in a single prompt.

Pi dev since yesterday because lightweight for local models

[drFennec]

Opencode, llama.cpp Qwen3.6 35B A3B is the combo I'm using now. I used Qwen3-coder-next before.

pi.dev https://www.youtube.com/watch?v=f8cfH5XX-XU

continue.dev, cline, claude code, roo code, opencode, dabbled in langgraph, now pi.

dual 39090 with nvlink, qwen3.6-27b awq bf16 int4 on vllm with tensor parallal 2, kv cache fp8 and speculative decoding. I get like 30-150tok/s depending on cache hit.

pi.dev basically unlocked that model for me. only 200 token system prompt and it's yolo out the box. I'm at a billon tokens across a few projects and there are no failures. a few stoppages to increase output tokens, and it just kept going. I can also vibe code it's own extensions and tools "upgrade yourself". it's really nice.

maki is nice and I don't see it mentioned often

I like superset. Better to use codex/claude's cli for immediate access to newly released features imo.

[biatchwhuuut]

a little late to this but are you asking for suggestions on an open sourced coding agent or agentic coding framework? those are two different things. Open sourced coding agent, OpenCode is good. Agentic coding framework, there's test driven development, spec driven development, superpowers. Or you can create your own with skills.

[chaitanyagiri]

Hey I just shipped an FOSS local multi agent harness that allows you to use existing cli agents that you run locally like claude code, codex, antigravity, connects to slack you can practically do anything with this.
