What is parallel-monitor?

A service that repeatedly checks web pages or searches on a schedule and reports when something changes. Unlike a one-time web search, a monitor keeps running until it is stopped.

Use it to create, list, inspect, update, test, or delete recurring web monitors and to review the changes they have detected.

It removes the need to manually revisit pages to notice changes such as updated prices, filings, or competitor information.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00090	$0.01148
Opus 5	$0.00045	$0.00574
Sonnet 5	$0.00018	$0.00230
Haiku 4.5	$0.00009	$0.00115

Security

Grade A, and why

parallel-monitor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Web Monitor

Action: $ARGUMENTS

Requires parallel-cli ≥ 0.3.0 (the monitor command was added in 0.3.0). If parallel-cli monitor errors with no such command or similar, tell the user to run parallel-cli update (or pipx upgrade parallel-web-tools if installed via pipx), 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 deleted and can optionally fire a webhook on each event.

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 / query / webhook for X"	update
"Test the webhook" / "Fire a test event"	simulate (requires a webhook on the monitor)
"Show me the full payload for event group X"	event-group
"Stop / delete monitor X"	delete (always confirm before deleting)

Create a monitor

parallel-cli monitor create "<query>" --cadence daily --json

Cadence options: hourly, daily (default), weekly, every_two_weeks. Match cadence to how often the source actually changes — hourly for prices/news, weekly for filings/staffing.

Optional flags:

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

Parse the JSON to extract the monitor_id. Tell the user:

The monitor has been created with its ID
The cadence (so they know when to expect first event)
That events accumulate server-side — they can run parallel-cli monitor events $MONITOR_ID later to see what changed

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

parallel-monitor is a skill published in the GitHub repository parallel-web/parallel-cursor-plugin (3 stars, last pushed 4mo ago), licensed MIT. It adds 90 tokens to every session and 1,148 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
