Hey,
Codex performs best in its harness. It also has best in class compaction features.
I was wondering if opencode could support
- Codex tool suite when using codex models
- Codex native compaction
- Codex's experimentlal steering, as impld in the codex repo.
Ik this is a lot but also codex is kinda the best coding model out rn and will likely stay in the top contenders for like a year so it would be pretty cool if we could use opencode but still get the same features and performance. thank you for your consideration !

Opened a PR for the steering portion of this request (Codex-style steer while busy + TUI/API wiring): #14813.\n\nThis does not implement the other items in this issue (tool suite/native compaction).

Superseding previous PRs with a clean rebased PR for the STEER portion: #14815.
