Tmux Notify

Shows OpenCode agent activity status in your tmux window name — without overwriting it.

Instead of replacing the window name, this plugin prepends a status icon:

Install

opencode plugin @erzhtor/opencode-tmux-notify --global

Or add to opencode.json:

{ "plugin": ["@erzhtor/opencode-tmux-notify"] }

Configure

type Options {
  working?: string | { spinner: string; spinMs?: number }
  waiting?: string | { icon: string }
  error?:   string | { icon: string; clearMs?: number | "never" }
  done?:    string | { icon: string; clearMs?: number | "never" }
}

• working — string for static icon, or { spinner, spinMs } for animation. Default: heavy braille spinner at 80ms.
• waiting — icon when agent is blocked waiting for your input (e.g. asking a question). Default: ⚠. Always persists until the agent resumes.
• error — icon when agent encounters an error. Default: ✘, persists by default.
• done — icon when agent finishes. Default: ✔ with 5000ms auto-clear.
• clearMs: "never" — keep the icon until the next state (for error and done only). Omitting clearMs defaults to "never" for error, and 5000 for done.

Examples

Use defaults:

{ "plugin": ["@erzhtor/opencode-tmux-notify"] }

Static icons + persist done forever:

["@erzhtor/opencode-tmux-notify", { "working": "⏳", "done": "✅" }]

Custom spinner + flash error:

["@erzhtor/opencode-tmux-notify", {
  "working": { "spinner": "◐◓◑◒", "spinMs": 120 },
  "done":    { "icon": "✓", "clearMs": 10000 },
  "error":   { "icon": "⚠", "clearMs": 5000 }
}]

Disable waiting/error:

["@erzhtor/opencode-tmux-notify", {
  "waiting": null,
  "error": null
}]

Spinner presets

braille — dots walking around:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "⠋⠙⠹⠸⠼⠴⠦⠧⠇⠏" } }]

heavy braille (default) — denser 8-dot pattern:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "⣷⣯⣟⡿⢿⣻⣽⣾" } }]

arcs — crescent rotations:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "◜◠◝◞◡◟" } }]

half-circles — rotating circle fills:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "◐◓◑◒" } }]

quadrant squares — corner fills rotating:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "◰◳◲◱" } }]

quadrant circles — quadrant fills rotating:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "◴◷◶◵" } }]

quadrant blocks — block fills rotating:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "▖▘▝▗" } }]

triangles — corners rotating:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "◢◣◤◥" } }]

block pulse — growing/shrinking bar:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "▁▂▃▄▅▆▇█▇▆▅▄▃▂" } }]

arrows — compass cycle:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "←↖↑↗→↘↓↙" } }]

classic ascii — universal:

["@erzhtor/opencode-tmux-notify", { "working": { "spinner": "|/-\\" } }]

How it works

State	Icon	Trigger
Working	⣷	Agent starts generating a response
Waiting	⚠	Agent needs your input (question, permission)
Error	✘	Agent encounters an error
Done	✔	Session becomes idle
Clean	—	After clearMs timeout, or on exit

• Multi-instance safe: Uses $TMUX_PANE with -t targeting — each OpenCode instance only modifies its own window
• No-op outside tmux: Silently returns if $TMUX_PANE is not set
• No shell injection: Uses execFileSync (no shell interpolation)
• Exit cleanup: Strips the icon when OpenCode exits
• Debounced: Only sets the working icon once per agent turn
• State priority: waiting > error > done — a blocked agent isn't truly idle
