README
opencode-tab-spinner
[](https://github.com/dsaveliev/opencode-tab-spinner/actions/workflows/ci.yml) [](LICENSE) [](https://nodejs.org) [](#) [](https://opencode.ai/docs/plugins)
An [opencode](https://opencode.ai) plugin that animates your terminal tab title while the agent is working — the behavior Claude Code users know: a spinner while the model runs, a check mark when it waits for you.
tab title while working: ⠋ myproject ⠙ myproject ⠹ myproject …
tab title when idle: ✓ myprojectWorks with any OSC-capable terminal: **Ghostty**, Kitty, WezTerm, iTerm2, xterm and friends. No configuration required.
How it works
opencode plugins receive in-process session events. The plugin listens for them and writes an OSC 0 title sequence to the TUI process's own `/dev/tty` — so every tab is isolated for free, and the signal is exact:
session.statusbusy/idle brackets every LLM call and gives an instant idle at turn endmessage.part.delta(the per-token stream) keeps the animation alive through reasoning and tool execution- a trailing metadata update of your last message (arriving ~60 ms after the turn ends) is recognized and ignored — the spinner never resurrects after a finished turn
The signal contract was verified empirically against opencode 1.18.x and is protected by 23 regression tests, several of them rehearsals of real production incidents.
