Bug: `omc team` tmux worker panes collapse to 1 column in npm runtime (`bridge/cli.cjs`)

[emreozenses]

Hi, we found a reproducible geometry bug in the active npm runtime path of OMC team mode on macOS + tmux.

Environment:

• macOS
• tmux
• npm/global install of oh-my-claude-sisyphus
• team mode via omc team ...

Symptom:
omc team starts, but worker panes collapse to 1-column width, which makes prompts unreadable and causes waitForPaneReady to time out.

Observed before local hotfix:

• window: 80x24
• leader pane: about 78x24
• worker panes: 1x24 / 1x8 / 1x7
• waitForPaneReady timed out repeatedly

Important finding:
This is not a raw tmux bug on our machine.
A detached raw tmux test works correctly:

• new-session -d -x 200 -y 50
• split-window -h -l 50%
  Result:
• window: 200x50
• panes: about 99x50 and 100x50

Root cause we identified:
The active execution path is not the cached plugin copy, but the npm runtime file:
~/.nvm/versions/node/v22.22.0/lib/node_modules/oh-my-claude-sisyphus/bridge/cli.cjs

In that file, the team session creation path is missing geometry controls:

1. new-session is missing -x 200 -y 50
2. split-window is missing -l 50%

Because of that, the session starts with default 80x24 geometry and worker panes collapse.

Local hotfix that solved geometry for us:

1. Add -x 200 -y 50 to the new-session call
2. Add -l 50% to the split-window call

After local hotfix:

• window became 200x50
• leader pane became 80x50
• worker pane became 119x50
• waitForPaneReady timeout disappeared

So the geometry issue appears fixed by those 2 changes in bridge/cli.cjs.

Suggested upstream fix:
In the active npm runtime file bridge/cli.cjs, update the team session creation path to:

• create detached tmux sessions with explicit geometry
• create worker splits with explicit width percentage

Optional follow-up:
Mixed worker geometry is now correct for us, but we still need to validate worker count / state cleanup separately. That appears to be a different issue, not the geometry issue.

If helpful, I can provide:

• exact before/after pane size outputs
• local patch diff
• reproduction commands

Thanks — this looks like a concrete reproducible bug in the active npm runtime path, not just local tmux weirdness. I'm opening a fix session now to verify the geometry path in bridge/cli.cjs / current source and patch it from current dev.

Thanks — confirmed on our side as well. We have a local hotfix in the active npm runtime path that restores correct tmux geometry and removes the pane readiness timeout. We’ll keep validating mixed worker count / completion separately and can share any additional logs if useful.
