## What it does

A monitor is a long-running server job, not a one-shot lookup. It stays alive until you cancel it and emits an event when it detects a change. You read those events through the CLI or have them delivered to a webhook.

Creation defaults to an `event_stream` monitor with frequency `1d` and the `lite` server processor. Frequency takes the form `<n><unit>` with `h`, `d` or `w`, from 1 hour to 30 days, and aliases like `hourly` and `weekly` also work. A `snapshot` monitor needs an existing Task run ID.

You need `parallel-cli` 0.4.0 or newer and internet access. If a monitor command or option is missing, update the CLI through your installation method and retry. Cancellation is irreversible — it is not a pause or a delete — so the skill asks you to confirm the exact monitor ID before running `cancel`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parallel-web/parallel-agent-skills --skill parallel-monitor -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/parallel-monitor/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/parallel-monitor/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parallel-web/parallel-agent-skills --skill parallel-monitor -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/parallel-monitor/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parallel-web/parallel-agent-skills --skill parallel-monitor -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/parallel-monitor/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parallel-web/parallel-agent-skills parallel-monitor
```

2. **Manually: put the files in place**
- File: `.github/skills/parallel-monitor/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parallel-web/parallel-agent-skills --skill parallel-monitor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parallel-web/parallel-agent-skills --path skills/parallel-monitor
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/parallel-monitor/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parallel-web/parallel-agent-skills --skill parallel-monitor -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/parallel-web/parallel-agent-skills/tree/HEAD/skills/parallel-monitor/SKILL.md

## When to use it
- set up a recurring check on a competitor page
- route change events to a webhook
- see what changed since the last check
- change the polling frequency of an existing monitor
- stop a monitor you no longer need

## Example prompts
- Track price changes for iPhone 16
- Show me events for monitor $MONITOR_ID
- Monitor the competitor pricing page weekly

# Web Monitor

Action: $ARGUMENTS

> Requires `parallel-cli` ≥ 0.4.0 for the GA Monitor commands. If a Monitor command or option is missing, tell the user to update through their installation method (see <https://docs.parallel.ai/integrations/cli>), then retry.

## What this skill does

Monitors are long-running, server-side jobs that re-check the web on a cadence and emit events when something changes. Unlike search/research/findall (one-shot lookups), monitors persist until cancelled and can optionally deliver detected events through a webhook. Creation does not establish an ongoing agent notification service: explain how to read server-side events or use the configured webhook, without promising chat or email alerts.

The default type is `event_stream`, with frequency `1d` and server processor `lite`. A `snapshot` monitor requires an existing Task run ID. Create or modify only the resource requested by the user; do not create a monitor just to demonstrate the skill.

## Decide the action

Parse the user's request and pick one:

| Intent | Action |
|---|---|
| "Track / watch / monitor / alert me when X" | **create** |
| "What am I monitoring?" / "List monitors" | **list** |
| "What changed?" / "Show me events for monitor X" | **events** |
| "Show monitor X" / "Get details for X" | **get** |
| "Change cadence / webhook for X" | **update** |
| "Check monitor X now" / "Run it now" | **trigger** |
| "Show me the full payload for event group X" | **events** with `--event-group-id` |
| "Stop / delete monitor X" | **cancel** (permanent; verify authority and exact ID) |

## Create a monitor

```bash
parallel-cli monitor create "<query>" --frequency 1d --json
```

Frequency accepts `<n><unit>` with `h`, `d`, or `w` (for example `1h`, `1d`, or `1w`), within the supported range of 1 hour to 30 days. The aliases `hourly`, `daily`, `weekly`, and `every_two_weeks` are also accepted. Match cadence to the user's request and how often the source actually changes.

Optional flags:

- `--webhook https://example.com/hook` — deliver detected events to a URL
- `--metadata '{"team":"competitive-intel"}'` — attach JSON metadata for your own bookkeeping
- `--output-schema '<json>'` — structure the event payload (advanced)
