Website Monitor

Overview

Periodic watch with quiet success. Store a baseline fingerprint; notify on delta.

Workflow

Define URL, CSS/text target, and what counts as a change.
Fetch current content with web_fetch, or the browser tool when the page renders client-side.
Normalize (strip volatile bits: dates, CSRF tokens, ads).
Compare to baseline file e.g. monitoring/<slug>.json in the workspace:
- hash or extracted fields (price, status, headline)
If changed: update baseline + notify with old → new.
Schedule via:
- cron when the user wants reports in chat
- .navin/HEARTBEAT.md when silence is preferred unless changed

Baseline schema

{
  "url": "...",
  "extracted": {"price": "12.00", "status": "in_stock"},
  "hash": "...",
  "checked_at": "..."
}

Rules

Do not spam on every HTML churn - compare extracted fields.
Include the URL and timestamp in alerts.

# Website Monitor

## Overview

Periodic watch with quiet success. Store a baseline fingerprint; notify on delta.

## Workflow

1. Define URL, CSS/text target, and what counts as a change.
2. Fetch current content with `web_fetch`, or the `browser` tool when the page renders client-side.
3. Normalize (strip volatile bits: dates, CSRF tokens, ads).
4. Compare to baseline file e.g. `monitoring/<slug>.json` in the workspace:
   - hash or extracted fields (price, status, headline)
5. If changed: update baseline + notify with **old → new**.
6. Schedule via:
   - `cron` when the user wants reports in chat
   - `.navin/HEARTBEAT.md` when silence is preferred unless changed

## Baseline schema

```json
{
  "url": "...",
  "extracted": {"price": "12.00", "status": "in_stock"},
  "hash": "...",
  "checked_at": "..."
}
```

## Rules

- Do not spam on every HTML churn - compare extracted fields.
- Include the URL and timestamp in alerts.
