People are misreading agentic bash/CLI use.

Stop viewing Bash as just a programming syntax or some LLM function calling tool use from 2024.

It’s not "coding." It's giving an agent a full computer to solve problems. Just happens to be a *nix computer where the shell is the interface; the CLIs are the apps.

[Preston Holmes @ptone]

Everyone is familiar with "HITL" for agent flows, but really that is just one class of a broader "condition in the loop" an async block on some condition being true. That might be a human approval, but it could also be a deploy being done, or another agent finishing some work. Complex workflows often are best modeled as an event driven flow, this will be true for many agent scenarios.

@rseroter @antigravity LLM calls are super async and easy. But when every agent needs to run build and tests that is one first area where container based remote agents get handy. If only there was a way…😊😉

@addyosmani Im strongly convinced we are entering the era where agents managing agents is viable. It’s early. But this world moves fast.

@LyalinDotCom Well. At least you have WiFi. Squirrels chewed my fiber drop at the pole and I’ve been without all weekend 🤣

The power of Scion being harness agnostic is that we can support Antigravity CLI on day one!

Repo below

gemini -m gemini-3.5-flash

you can get 3.5 flash in Gemini CLI right away

@dexhorthy But sometimes the best control flow looks like this:

@LyalinDotCom Another good series: https://t.co/kcYcMNnEm3

@dotta This is a crux challenge for distributed multi agents! One you didn’t mention is Kubernetes volumes backed by things like glusterFS. Lots of care and feeding. In GCP we have Managed NFS file store but $$. The options aren’t awesome. Great thread!

[Preston Holmes @ptone]

When your agents use tmux to 👀at other agents TUI with tmux to reason about what they are doing. It’s the ascii of computer use model intelligence.

[Preston Holmes @ptone]

@dexhorthy @GeoffreyHuntley Who knew tmux would have such a resurgence in the year 2026. TUIs are the ascii version of computer use models.

@BryceKaiser @dotta Been doing this and experimenting with multi user permissions in Scion for a while ;-)

@JackWoth98 @rseroter You gotta try crossover to chat !

[Preston Holmes @ptone]

🤔 Now I’m off to think about how to turn this into a coding agent skill…

@CTOAdvisor @rseroter Would love to give you a walk through of how Scion could plug into such a project

@clawdylabs @geminicli 100% composable and compatible. Scion agents will be running on Cloud Run by the sandbox public preview.
