dsh-plugin-node-time

Hover timestamps for DSH web. Hovering a chat node row — Think, Bash, Read/Edit/Write, Search, commands, compaction markers, sub-calls — pops a compact card with that node's start time → end time and how long it took.

The card

11:30:05.123 → 11:30:09.123
4.00s

• Range line — start → end in your local timezone; the date prefix appears when the node didn't happen today (and the year when it wasn't this year). A still-running node shows start → … with the elapsed time ticking every second; the line flips to the final range the moment the call settles.
• Duration line — humanized: 830ms / 4.33s / 1m 23s / 1h 02m 30s.
• Extra line — assistant steps also show TTFT (time to first token) when the step has recorded one.
• Styling rides the host's --dsw-alias-* design tokens, so it follows your theme; the card is pointer-events: none and never intercepts the mouse.

What gets a card

Row	Start	End
Tool rows (Bash, Read, Edit, Search, …) and every nested sub-call	tool/call time	tool/result time
Think rows and assistant steps	step/start time	assistant/message time
Commands, compaction, turn errors, retries, context rows	—	event time (single line)

Rows whose times the host already shows on hover (user messages, the turn tail) are left untouched, and a node whose call event fell outside the loaded history window simply shows what exists — or nothing.

How it works

• Trigger — one delegated mouseover/mouseout pair on document (capture). A hit on a row header — [data-disclosure-row] (generic tool rows, Think, commands) or [data-sample] (the Bash/Pwsh sample card, whose expanded output lives outside the row root, so sweeping output never pops the card) — resolves through data-chat-call-id (exact tool-call/sub-call attribution) or data-chat-anchor-key (chat node), then reads the timing out of the current session snapshot — read at hover time, so it is always fresh.
• Data — the sessions service: ToolChatData.root lifecycle (callTime/time), AssistantChatData.finalNode.timing (stepStartTime/firstTokenTime/completedTime), node.location.step boundary events for running steps, and data.time for single-time nodes.
• Zero host DOM writes — the card is a position: fixed element appended to document.body; React re-renders can never wipe it, and no host component is replaced or patched.
• Style contract — the injected <style> arrives pre-tagged with data-plugin="dsh-plugin-node-time": the client module system's claimStyles re-assigns every untagged head style to whichever plugin materializes next (HMR bookkeeping), so an untagged style gets claimed — and possibly cleaned up — by a neighbour. (This exact race is why v0.1.0 cards sometimes never appeared.)
• Silent by design — missing sessions service, changed contracts, or truncated windows degrade to "no card"; the plugin can never break the host.

Install

dsh plugin --profile web add dsh-plugin-node-time

Restart dsh web to take effect.

From source (local development)

pnpm install
pnpm run build
