Conversation rhythm:
- Single `--paragraph-gap` knob drives paragraph spacing both inside a
markdown block and between consecutive prose parts, out-specifying Tailwind
Typography's prose margins. Code cards carry the same gap themselves so it
holds at any Streamdown nesting depth.
- Two-tier vertical rhythm: `--turn-block-gap` separates scaffolding (tools /
thinking) from the reply; `--tool-row-gap` keeps a tool run tight.
- Drop the prose indent so prose, tools, todos, and thinking share one left
edge. `---` renders as quiet spacing, not a heavy rule.
Flat tool list:
- Tools always render as a standalone-row stack, never a "Tool actions · N
steps" group. assistant-ui slices the tool range unstably (interleaved live
vs. reconstructed-consecutive when settled), so grouping reshuffled the whole
turn the instant it settled. Flat rows are pixel-identical either way.
- Inline approvals can no longer be buried in a collapsed group body.
- Remove the now-dead grouping helpers from tool-fallback-model.
Empty thinking:
- Suppress reasoning disclosures with no visible text (encrypted / spinner-
coerced reasoning) instead of leaving an empty "Thinking" header.
- Tail stall indicator returns "thinking" when a running turn goes quiet.
Streaming cadence:
- Smooth character-reveal decouples visible cadence from bursty arrival.
- Flush queued text deltas before applying tool events so a tool row can't
jump ahead of its preceding text.
- Disable Nagle on the GUI WebSocket so per-token frames aren't coalesced.
Polish: clarify/patch/vision_analyze tool meta, queue-panel + diff-lines
spacing, sticky human bubble expands on focus (not hover).
