Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-04 (score 68, +1)

No change was recorded against any check on this day. Stability & Change Management went from 27 to 30. That category is still filling its 30-day observation window: 8 days of observed history at the previous scan, 9 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (8)

### `comet_connect` (~20 tokens)

Connect to Comet browser (auto-starts if needed)

### `comet_ask` (~110 tokens)

Send a prompt to Comet/Perplexity and wait for the complete response (blocking). Ideal for tasks requiring real browser interaction (login walls, dynamic content, filling forms) or deep research with agentic browsing.

Input parameters:

- `newChat` (boolean): Start a fresh conversation (default: false)
- `prompt` (string, required): Question or task for Comet - focus on goals and context
- `timeout` (number): Max wait time in ms (default: 15000 = 15s)

### `comet_poll` (~22 tokens)

Check agent status and progress. Call repeatedly to monitor agentic tasks.

### `comet_stop` (~19 tokens)

Stop the current agent task if it's going off track

### `comet_screenshot` (~16 tokens)

Capture a screenshot of current page

### `comet_tabs` (~109 tokens)

View and manage browser tabs. Shows all open tabs with their purpose, domain, and status. Helps coordinate multi-tab workflows without creating duplicate tabs.

Input parameters:

- `action` (string): Action to perform: 'list' (default) shows all tabs, 'switch' activates a tab, 'close' closes a tab
- `domain` (string): For switch/close: domain to match (e.g., 'github.com')
- `tabId` (string): For switch/close: specific tab ID

### `comet_mode` (~73 tokens)

Switch Perplexity search mode. Modes: 'search' (basic), 'research' (deep research), 'labs' (analytics/visualization), 'learn' (educational). Call without mode to see current mode.

Input parameters:

- `mode` (string): Mode to switch to (optional - omit to see current mode)

### `comet_upload` (~137 tokens)

Upload a file to a file input on the current page. Use this to attach images, documents, or other files to forms, posts, or upload dialogs. The file must exist on the local filesystem.

Input parameters:

- `checkOnly` (boolean): If true, only checks if file inputs exist on the page without uploading
- `filePath` (string, required): Absolute path to the file to upload (e.g., '/home/user/image.png' or 'C:\Users\user\image.png')
- `selector` (string): Optional CSS selector for the file input element. If not provided, auto-detects the first file input on the page.
