# 2026-07-14 — Unified agent activity indicator
|
|
|
|
**Status:** Planned
|
|
|
|
## Current state — three separate indicators
|
|
|
|
| Component | Location | Shows |
|
|
|---|---|---|
|
|
| Loading dots (Chat.svelte:146) | Inline in assistant bubble | 3 bouncing dots when no text/tools yet |
|
|
| ToolCallGroup trigger row | Inline in assistant bubble | "12 tools" with spinner |
|
|
| Activity bar | Bottom of message list | "Agent is responding…" / "Working" / Continue button |
|
|
|
|
All three overlap. The operator sees dots → then a tool count → then the activity bar — three different visual styles for the same thing: "the agent is working."
|
|
|
|
## Target: single indicator appended to conversation
|
|
|
|
One row, always the last item in the message list, that replaces the loading dots, ToolCallGroup summary, and activity bar. Think of it like a system message appended at the end of the conversation.
|
|
|
|
### Behavior
|
|
|
|
```
|
|
User: "audit fleet"
|
|
Assistant: "I'll check all hosts. Here's the plan..." ← full message bubble
|
|
|
|
┌─ Agent is auditing… ───────────────────┐
|
|
│ ◉ apt update on lxc:jellyfin │ ← spinner + current action
|
|
└────────────────────────────────────────┘
|
|
|
|
... agent finishes ...
|
|
|
|
Assistant: "Done. 19 LXCs have pending updates." ← next message bubble
|
|
```
|
|
|
|
The indicator:
|
|
- **Appears** when the agent starts working (first `tool_use` event or `streaming=true`)
|
|
- **Updates** its description with the current tool name in flight
|
|
- **Collapses/disappears** when the turn ends (`done` event or `streaming=false`)
|
|
- If there were tools, shows a brief completion summary for 3 seconds then fades
|
|
- During auto-continuation (polling picks up new messages), reappears if the agent did tool calls
|
|
|
|
### States
|
|
|
|
| State | Icon | Description |
|
|
|---|---|---|
|
|
| Thinking | ◉ pulse | "Agent is thinking…" |
|
|
| Planning | ◉ pulse | "Building plan…" |
|
|
| Researching | ◉ pulse | "Researching <entity>…" |
|
|
| Executing | ◉ spinner | "<tool_name> <target>…" |
|
|
| Done | ✓ | Fades out after 3s |
|
|
|
|
### Data source
|
|
|
|
The description comes from the most recent `tool_use` event's name + args. If no tools yet, show generic "thinking" message. The derived `toolTimeline` store already has this data.
|
|
|
|
## Implementation
|
|
|
|
### 1. New component: `AgentIndicator.svelte`
|
|
|
|
**Props:** `active: boolean`, `lastTool: ToolCallResult | null`, `toolCount: number`
|
|
|
|
Renders a single compact row:
|
|
```html
|
|
<div class="activity-indicator">
|
|
<LoaderCircle class="animate-spin" /> <!-- or CheckIcon when done -->
|
|
<span>{label}</span>
|
|
</div>
|
|
```
|
|
|
|
`label` is derived:
|
|
```ts
|
|
const label = $derived.by(() => {
|
|
if (!active) return ''
|
|
if (!lastTool) return 'Agent is thinking…'
|
|
const args = lastTool.args ?? {}
|
|
switch (lastTool.name) {
|
|
case 'set_goal': return 'Setting goal…'
|
|
case 'propose_plan': return 'Building plan…'
|
|
case 'search_knowledge': return `Researching: ${args.query ?? ''}`
|
|
case 'get_entity': return `Looking up ${args.slug_or_id ?? ''}`
|
|
case 'run': return `${args.purpose ?? 'Running command…'}`
|
|
case 'list_lxcs': return 'Listing containers…'
|
|
case 'update_plan_step': return 'Updating progress…'
|
|
case 'upsert_knowledge': return 'Recording knowledge…'
|
|
case 'complete_task': return 'Wrapping up…'
|
|
default: return `${lastTool.name}…`
|
|
}
|
|
})
|
|
```
|
|
|
|
### 2. Chat.svelte changes
|
|
|
|
- **Remove** activity bar from bottom of messages
|
|
- **Replace** the 3 bouncing dots `{#if msg.tools.length === 0}` with nothing (the indicator covers this)
|
|
- **Add** `<AgentIndicator>` after the `{#each}` loop, before `messagesEnd`
|
|
- The indicator shows when `$streaming || liveStatus === 'executing'`
|
|
- Pass `lastTool` from `$toolTimeline` — the last tool_use entry
|
|
|
|
### 3. Remove activity bar code
|
|
|
|
Delete the `{#if $currentSession && $messages.length > 0}` block at the bottom (already moved once, now deleted entirely — replaced by AgentIndicator).
|
|
|
|
### 4. Remove loading dots
|
|
|
|
In Chat.svelte, remove the 3 bouncing dots block:
|
|
```svelte
|
|
{:else if msg.tools.length === 0}
|
|
<div class="flex items-center gap-1.5 py-1 text-sm text-muted-foreground">
|
|
<span class="size-1.5 animate-bounce rounded-full bg-current ...">...</span>
|
|
</div>
|
|
```
|
|
|
|
## Verification
|
|
|
|
- Send "status" → indicator appears "Agent is thinking…" → agent responds → indicator fades
|
|
- Send "check updates on jellyfin" → indicator shows "Researching…" → "Listing containers…" → "Running apt list…" → fades
|
|
- Auto-continuation fires → indicator reappears with current tool → fades when done
|
|
- Scroll up during agent work → indicator stays at bottom of message list (it's just a message)
|
|
- Error during agent work → indicator shows "Error: …" with X icon
