## Why Included

T3 Code can now run fx as a provider across web, desktop and mobile, with Supervised and Auto modes plus fx's existing models and skills.

## Source Summary

The open-source coding agent harness fx is now available as a provider in T3 Code on **web, desktop and mobile**. Its provider supports **Supervised and Auto modes** and the models and skills already used with fx.

## Practical Implication

If you use T3 Code to manage coding sessions, install fx, configure a model provider, then add fx under Settings > Providers.

## Agent-Ready Context

The open-source coding agent harness fx is now available as a provider in T3 Code on **web, desktop and mobile**. Its provider supports **Supervised and Auto modes** and the models and skills already used with fx.

If you use T3 Code to manage coding sessions, install fx, configure a model provider, then add fx under Settings > Providers.

The material describes the integration but gives no details on differences between modes or any limits on supported models and skills.

## Connected Context

Feed7 judgment across 955 accumulated Signals:

T3 Code can now host fx sessions across web, desktop, and mobile, carrying fx's existing models and skills into those surfaces. The integration widens where users can manage fx, but the supplied details do not explain how Supervised and Auto modes differ or which configurations they support.

- [cline/cline](https://feed7.dev/p/cline-03xl2ea) — Cline spans IDE, CLI, desktop, SDK, and automation from one agent core; the fx integration similarly brings an existing harness into multiple host surfaces, though its supplied scope is narrower.
- [openai/codex](https://feed7.dev/p/codex-1jzl221) — Both make a coding agent available across several interaction surfaces; fx's T3 Code listing adds web, desktop, and mobile access while leaving mode behavior unspecified.
- [anomalyco/opencode](https://feed7.dev/p/opencode-1ukzh4a) — OpenCode's supplied brief defines distinct read-only and full-access modes, providing a clear access-control contrast to fx's Supervised and Auto labels, whose behavior is not detailed here.
