This is Parallel's own monitoring skill. Claude uses parallel-cli monitor to create a monitor for a query, list or inspect monitors, read what changed, change the schedule, run one extra check, or cancel it. Monitors live on Parallel's servers and keep running until cancelled.

It needs parallel-cli 0.4.0 or newer, signed in and funded. The folder holds only SKILL.md and bundles no scripts.

Good for

Anyone tracking price changes, filings or competitor pages over time
Teams who want change events sent to a webhook
Developers managing monitors from the terminal

Install parallel-monitor

Claude Code

Copy this prompt.

Install the parallel-monitor skill in Claude Code. Run this command:

/plugin marketplace add parallel-web/parallel-agent-skills
/plugin install parallel

Then check that it loaded and tell me how to use it.

2
Paste it into Claude Code. It shows the change and asks before running it.

Pick one route. The plugin installs all 15 skills (counted from the repo), a hosted Parallel Search MCP server (parallel-search, anonymous) and a Bash-only agent called parallel-subagent. Restart Claude Code after installing it. This skill needs parallel-cli installed, signed in and funded; the second method in each tab lists the install commands from the repo's setup skill, and /parallel:parallel-cli-setup runs them for you. In Codex, use $ instead of / for skill names. The repo's .agents/skills folder, which Codex reads inside a clone, links 12 of the 15 skills and not this one.

What's in the skill

When it loads

Continuously track the web for changes on a recurring cadence. Use when the user asks to 'monitor', 'track changes to', 'watch', or 'alert me when' something on the web changes — e.g., 'Track price changes for iPhone 16', 'Alert me when Tesla files a new 8-K', 'Monitor competitor pricing pages weekly'. Also use to list, inspect, update, or stop existing monitors, including requests to delete them.

What it includes

Starts a server-side monitor for a query, checking on a cadence such as 1h, 1d or 1w
Defaults: type event_stream, frequency 1d, processor lite. Range is 1 hour to 30 days. A snapshot monitor needs an existing Task run ID.
Try: “Track price changes for the iPhone 16 Pro”
Runs code · monitor create
Lists active monitors, or shows one by ID
Cancelled monitors appear only if you ask. Use get, not list, to verify a new monitor.
Runs code · monitor list / get
Shows detected changes, newest first, with optional completions and errors
An empty list does not prove a check ran. Add --include-completions to see run history.
Runs code · monitor events
Changes frequency, webhook or metadata for a monitor
The query and Task run identity cannot be changed.
Runs code · monitor update
Runs one extra check now, billed, without changing the schedule
Runs code · monitor trigger
Stops a monitor permanently
Claude should confirm the exact ID, then check the state with get.
Delete · monitor cancel
--webhook, --metadata and --output-schema on create
Runs code · Options

Watch out for

Monitors keep running and keep billing
SKILL.md says monitors persist until cancelled, and recreating one can duplicate persistent monitoring and billing. Ask Claude to list active monitors when you finish. github.com
Trigger runs a real billed check
`monitor trigger` enqueues an off-schedule execution that is billed. SKILL.md says it is not a webhook test. github.com
Cancel is permanent
SKILL.md says cancellation is irreversible, not a pause or deletion. Claude should confirm the exact monitor ID with you first, unless you already authorized that cleanup. github.com
Webhooks send events to the URL you choose
With --webhook, Parallel delivers detected events to that address. Use an endpoint you control and keep secrets out of the query text. github.com
Your queries are sent to Parallel
The README says task inputs go to Parallel's API under its Customer Terms and Privacy Policy, and tells you not to send secrets or sensitive local content. Review what Claude puts in a request. github.com
It runs against your funded Parallel account
The README says CLI-backed skills are billed as ordinary API usage on your own Parallel account. Check current pricing on the vendor site before large runs. github.com
The setup path installs and signs in a CLI
The repo's setup skill installs parallel-cli (brew, uv, npm or pipx), starts a device sign-in, and points to `parallel-cli balance add` for top-ups. The search and research skills say never to add funds without explicit confirmation. github.com

Technical details

Turning on read-only	There is no read-only switch. The skill runs parallel-cli commands that call Parallel's API under your account.
Sign-in and keys	parallel-cli signs in with a device OAuth flow you approve in a browser. The README says CLI-backed skills use credentials you already configured.
Scopes	Runs parallel-cli through Bash (allowed-tools: Bash(parallel-cli:*)) Creates, updates, triggers and cancels monitors that run on Parallel's servers Can send detected events to a webhook URL you give

Questions

What does the parallel-monitor skill do?

It makes Claude set up and manage Parallel web monitors with parallel-cli monitor. A monitor re-checks the web on a schedule and records an event when something changes. You can create, list, inspect, update, trigger and cancel them.

How do I install parallel-monitor?

Use the install box above. The plugin installs it with 14 other skills. Then install and sign in to parallel-cli, version 0.4.0 or newer.

Will it email or message me when something changes?

Not by itself. SKILL.md says creation does not set up a notification service. Events are stored server-side and you read them with monitor events, or you give a webhook URL to receive them.

How often does a monitor check?

The default is once a day. You can set anything from 1 hour to 30 days, such as 1h, 1d or 1w, and the aliases hourly, daily, weekly and every_two_weeks.

How do I stop a monitor?

Ask Claude to cancel it by ID. SKILL.md says cancelling is permanent, not a pause, so Claude should confirm the exact ID first. Cancelled monitors cannot be triggered.

Does it cost money?

Yes. Monitors and triggered checks are billed to your own Parallel account, per SKILL.md and the README. The skill gives no prices. See the vendor's pricing page.

Is it safe?

It creates persistent jobs on Parallel's servers that keep billing until cancelled, and it can point event delivery at a webhook. Our advice: ask for one monitor at a time, note its ID, and list active monitors when you are done.

Is it an official Parallel skill?

It is in Parallel Web Systems' own repo, and the repo's marketplace.json describes the plugin as the "Official Parallel Web Systems plugin for Claude Code".
