# Live Watch

Watch the dashboard's live counters change over a short window by polling
`/api/stats` a few times and reporting the deltas.

## Input

The user provides: **$ARGUMENTS**

Interpreted as the watch shape: number of polls and/or interval (e.g. `5x3s` =
5 samples 3 seconds apart). Defaults when empty: **5 samples, ~3 seconds apart**
(a ~15-second window). A bare number means that many samples at the default
interval; a bare duration means the default sample count at that interval.

## Data Sources

| Endpoint | Returns |
|----------|---------|
| `GET /api/stats` (polled) | `{ total_sessions, active_sessions, active_agents, total_agents, total_events, events_today, ws_connections, agents_by_status, sessions_by_status }` |

## Method

Poll `GET /api/stats` once per interval for the configured number of samples,
recording the timestamp and the four watched counters each time. Pace the polls
with a short wait between requests; keep the total window short (seconds, not
minutes) so it stays interactive.

If the very first poll fails to connect, the dashboard is down — stop and tell
the user to start it with `npm start` (or `npm run dev`) from the repo root,
then retry.

## Report Sections

### 1. Watch Window
State the sample count, interval, and total elapsed window.

### 2. Sample Timeline
A Markdown table — one row per poll — with columns:
`#`, `time`, `active_sessions`, `active_agents`, `events_today`, `ws_connections`.

### 3. Deltas
For each of the four watched counters, report the net change from the first to
the last sample using ▲ (increase), ▼ (decrease), or `=` (no change). Note any
mid-window spikes or dips visible in the timeline.

### 4. Verdict
One line: is the dashboard actively receiving traffic (counters moving) or idle
(flat) over the window?

## Output

- Compact Markdown. The timeline table is the centerpiece.
- Cite real values from each poll — never interpolate or invent samples.
- Deltas use ▲/▼/= with the signed numeric change, e.g. `events_today: ▲ +7`.
- Keep it scannable in a terminal — no padding beyond the table.
