A plugin for OpenCode that displays a live Tokens Per Second (TPS) meter in the terminal UI — for the active session AND for every subagent it has spawned.
- Prompt readout — shows
TPS <n>on the right side of the prompt for the session you're viewing. - Sidebar section — when the current session has one or more subagents, the sidebar grows a
TPSsection listing the main agent and every subagent alphabetically, each with its live TPS. The section header shows the average TPS across every live agent in the section. - The sidebar section is conditionally rendered: if there are no subagents in the current session, nothing is added.
How TPS is calculated:
- Token deltas are sampled from
message.part.deltaevents on a 5 s rolling window. - A reading of
-means no tokens have streamed within the last ~1.5 s. - Counters clear automatically when streaming completes, errors out, or a tool call starts.
