dsh-response-meta

English | 中文

A DSH Web plugin that adds one always-visible runtime summary to every model reply: model, reasoning extent, tokens per second, timestamp, total runtime, and time to first token (TTFT).

The plugin hides the duplicate native timing group that normally appears on hover in the same assistant action row, while preserving timestamps on user messages. Manually interrupted replies, including replies stopped during reasoning, receive an inline summary as well.

Example in a Chinese UI (11 px muted text):

# Completed reply, below the message actions
deepseek-v4-pro · 思考 15 tok · 46 tok/s · 14:16 · 用时 2分24秒 · 首 token 2.1秒
# Interrupted during reasoning, inline in the message stream
deepseek-v4-pro · 思考 1.5k 字

• Model comes from the turn's request/header session event. Later turns without a new header inherit the most recent known model.
• Reasoning extent prefers provider-reported reasoning tokens and falls back to the reasoning text length.
• Tokens/s is output tokens divided by decode time, from first token to message completion, matching DSH's native timing semantics.
• Timestamp shows HH:mm for today's replies and includes the date for older replies.
• Total runtime spans the whole turn; TTFT spans the current step from start to its first token.
• Interrupted replies usually have no usage record, so the plugin shows the model and streamed reasoning extent. Real usage is retained when a finalization race provides it.
• Missing fields are omitted individually; nothing is rendered when all fields are unavailable.

Install

dsh plugin --profile web add github:Unintendedz/dsh-response-meta#v0.1.0

Restart the running DSH Web service after installation. Plugins are loaded when the service starts.

Local development

./scripts/install.sh   # remove + add to refresh the local file: snapshot
# Restart the DSH Web service afterward.

The script reuses the profile's configured pnpm storeDir, preventing ERR_PNPM_UNEXPECTED_STORE when run from a different shell. If the store was changed manually, relink it once:

cd ~/.dsh/profiles/web && pnpm install --config.confirm-modules-purge=false

Uninstall

dsh plugin --profile web remove dsh-response-meta

How it works

• Host (lib/index.js): registers a dependency-free projection unit on ctx.sessionProjections. It folds session events, tracks the active turn/step, records the last in-turn request/header model in byTurn, and inherits the previous model for header-less turns. Headers outside turns, such as title or compaction requests, are ignored. Projection updates reach the browser through DSH's existing session-projection channel. The plugin implements the rc2 projection contract (stateSchema + wire.viewSchema).
• Browser (lib/client.js):
  • Completed replies register in conversation.chat.assistant-actions. The component reads usage, step timing, turn timing, reasoning content, and the per-turn model projection for the exact messageId. A scoped structural selector hides only the native assistant timing group.
  • Interrupted, failed, or aborted steps register through a dsh-response-meta-aborted conversation event and a keyed conversation.chat.node entry. This also covers reasoning-only steps that never produced turn/end.
  • Actions remain on the first row; the complete summary owns a responsive second row. Narrow screens wrap without truncation or horizontal overflow.

Verify

npm test
node tests/live-e2e.mjs http://127.0.0.1:33880

The live test requires a DSH Web test server running this plugin. The browser scripts in tests/ cover interruption behavior and completed-row layout.
