Cline

Introducing the Cline SDK. We rebuilt the Cline harness for our extension and CLI from scratch using all the lessons learned since creating one of the world's first coding agents in 2024, and are open sourcing it for others to build with today. npm i @​cline/sdk 🧵

xAI just released grok-build-0.1 this morning, a new model built specifically for agentic coding 12x cheaper than Opus. Let's see what a million H100s worth of compute at their Colossus datacenter has been cooking 👀

. @aiDotEngineer I talk about how @cline we're on a mission to fight slop in coding agents. Slop is the worst part of building in this space. Scroll any timeline and you'll see people flexing about merging 100 commits a day. It creates a subconscious pressure to optimize for throughput with more agents and more commits. But take a step back: is that actually the right goal? Do we really believe more code and more agents is inherently better? What if we slowed down and sharpened the axe instead, investing in better baseline scaffolding, and building simpler but far more powerful agents that can handle millions of tasks seamlessly at scale? I dive deeper into this in my talk would love for you to give it a listen.

Agent infrastructure is becoming modular fast. @cline just open-sourced an SDK for building portable coding agents across apps, IDEs, CLIs and more. Hicap is proud to support it as an inference provider. Build your agents. We’ll handle the inference layer.

@ayayalar I am sorry to hear that. Reaching out via DM

@cline wayyy too many issues. Unusable at this time. Will go back to the older version.

@pyronaur Yes you can use it freely with codex subscription!

@cline can i use this with my codex subscription?

@ayayalar Please open GitHub issues so we can stay on top. Always polishing!

@cline I can confirm this is fixed!😀. There are lots of other issues though. I will keep updating to the latest as it becomes available.

@cline tui is broken. Cannot register local openai compatible provider.

@mekartikshah @alexc @deepseek_ai Please give a try to our CLI (built upon the upgraded harness) and the VS Code migration is landing soon!

@alexc @cline @deepseek_ai This started happening with me, few weeks back and very irritating- no solution on repo, end up switching to open code.

First time I've ever been model shamed... 🫡 I was using Cline in VS Code with Deepseek Pro V4.

@MKhalidTaher We'd love to learn more, are you using our latest CLI? Which OS are you on? Is there more detailed error message we can look at (if you can open an issue in our github with more details)? We will investigate soon We will check on GROK 4.3 and come back

@cline Tried GPT-5.5 with cline, keeps on crashing with 400 error. PLEASE ALSO ADD GROK 4.3!!!!

The new GPT-5.5 is #1 on Terminal-Bench at 82.7. This beats Anthropic’s Mythos Preview scoring 82.0, which they have not released to the public due to cybersecurity and safety concerns. Available in Cline now!

Build with Cline SDK! Here’s the Cline SDK multi-agent example in action that you can simply get started: github.com/cline/cline/tr… It spins up multiple specialist agents in parallel, streams each agent’s output live to a web UI with SSE, then synthesizes their results into one final answer. Build your own agent team app now!

@ayayalar can you dm me some more details or open a github issue? We will be on it soon

@alek_k13 @alexc @deepseek_ai Yes please try it back in a few weeks. Join our discord channel for beta testing on our nightly release! discord.com/channels/12755…

@cline @alexc @deepseek_ai Well, I shall try the IDE plugin again in a few weeks then ! I tried it with my local Qwen3.6 27B and it got into a loop never seen on Droid or OpenCode...

@quantumaidev yep!

@cline Is this approved by OpenAI? Don’t want to get banned…

@quantumaidev just use the chatgpt provider! type /settings and change your provider.

@cline How can I use this with my Codex plan?

@JDmakt you can use environment variables to set aws profile, keys, etc. see here: ai-sdk.dev/providers/ai-s…

@cline Can you please enable AWS profile or credentials for AWS bedrock and not only through API key. Similar to the vs code extension

@ieditormurata yes! works on all platforms.

@cline Is cline cli available for windows

@nicos_ai let us know how it works for you!

@cline Trying it out today 100%

@Chahatxsharma it was kinda crazy seeing how people tried to use the old harness made for vs code! glad we can make their lives easier 😌

@cline Pulling the harness out into a standalone SDK is the right call. Every team building on top of Cline was essentially doing this themselves anyway.

@ai_for_success the numbers speak for themselves 😌

@cline Most underrated part... Cline CLI at 74.2% on claude-opus-4.7, Claude Code at 69.4%.
