Web Monitor

SkillFiles & storage

Lets your agent continuously monitor websites for changes like prices or filings and alert you when something updates.

Available today. Use it from your connected AI after setup.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the Web Monitor skill

About this skill

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 weekl

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:

IntentAction
"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

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)

Capture the returned monitor_id immediately with the query, frequency and requested settings. Verify creation with get using that ID. Tell the user:

  • The monitor has been created with its ID
  • The frequency (so they know how often the monitor checks)
  • That recent events are available server-side — they can run parallel-cli monitor events $MONITOR_ID later to see what changed

If creation or another mutation times out or the response is lost, resolve the existing monitor/action before retrying. Resume with the saved ID, get and events; do not automatically recreate it. Recreating can duplicate persistent monitoring and billing.

List monitors

parallel-cli monitor list -n 10 --json

Default to -n 10 for concise output. list returns active monitors only by default; add --status active --status cancelled when the user asks to include cancelled monitors. Raise the limit only for a larger set. Present as a table: ID, query or Task Run (truncated), frequency, created.

Note: monitor list is sorted newest-first. If a user is verifying creation, prefer monitor get $MONITOR_ID (using the ID returned by create) over scanning the list.

View events for a monitor

parallel-cli monitor events "$MONITOR_ID" --json

Events are returned newest-first. If the response contains next_cursor, pass it with --cursor to retrieve another page.

An empty event list does not prove that a check completed without changes. To inspect completion history as well as detected events:

parallel-cli monitor events "$MONITOR_ID" --include-completions --limit 10 --json

Distinguish typed detected events, no-change completion events and error events. Use their actual timestamps and report failures. An empty completion history is not execution proof. Retain event_id and event_group_id when present; these identify events and executions, not monitor IDs.

For deeper detail on a specific event group:

parallel-cli monitor events "$MONITOR_ID" --event-group-id "$EVENT_GROUP_ID" --json

Event-group detail ignores pagination arguments. Summarize detected changes separately from completions/errors, with dates or timestamps. Read typed output or changed_output and available basis; cite its source URLs for factual claims. Do not invent provenance when the payload lacks basis. Surface response warnings and continue pagination only as needed for the requested period.

Get / update / trigger / cancel

parallel-cli monitor get "$MONITOR_ID" --json
parallel-cli monitor update "$MONITOR_ID" --frequency 1w --json
parallel-cli monitor update "$MONITOR_ID" --webhook https://example.com/hook --json
parallel-cli monitor trigger "$MONITOR_ID" --json
parallel-cli monitor cancel "$MONITOR_ID" --json

Only supply fields the user requested to update. A webhook-only update leaves frequency unchanged; update has no default frequency. Metadata and advanced event-stream settings can also be updated through the CLI, but query and Task run identity are immutable. A different query needs a new monitor with separate authority and a deliberate decision about the old monitor; do not silently recreate or cancel it.

trigger enqueues a real billed off-schedule execution without changing the regular schedule. It is not a synthetic webhook test and must not substitute for a request to test notification delivery. A successful trigger response confirms enqueueing, not completion. It emits a detected event only if material change is found; inspect completion history for no-change execution. Cancelled monitors cannot be triggered.

Cancellation is irreversible, not deletion or a temporary pause. Explain this and obtain confirmation for the exact monitor ID unless the user has already authorized that permanent cancellation or cleanup of the specific disposable monitor. After cancelling, verify its state with get. Never recreate it automatically to resume monitoring.

On authentication or API errors, report the actual error and retain IDs for recovery. Do not classify every error as an outdated CLI or every permission error as insufficient credit. Failed reads are not evidence that a monitor stopped; reading events does not cancel it.

Setup

Requires an installed and authenticated parallel-cli. Check parallel-cli --version and parallel-cli auth --json; auth can exit successfully while authenticated is false. Missing binary, unsupported command/option, and authentication failure need different remedies: installation, upgrade through the existing installation method, or terminal login respectively. See https://docs.parallel.ai/integrations/cli. Stop the affected request on auth failure, do not ask for secrets in chat, and do not change account policy to work around blocked setup.
