A skill for creating and managing recurring web checks through ArkSpace. It supports repeated searches or checks for changes to pages, sites, crawls, and search results, with schedules and optional notifications.

Use it to schedule search or website-change checks, inspect their history, pause or resume them, trigger an immediate run, or delete them.

A one-time search cannot tell you when public information changes. Recurring monitors perform the check later and retain results or change history.

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 5.1	$0.00056	$0.00964
Opus 5	$0.00028	$0.00482
Sonnet 5	$0.00011	$0.00193
Haiku 4.5	$0.00006	$0.00096

Security

Grade A, and why

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 2d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Monitor

Use the installed arks CLI or ArkSpace MCP tools. Use web.search for one-time discovery and research.run for one attached report.

Choose the contract

Do not present Firecrawl Monitor as an interchangeable Exa Provider:

Use monitor.* for Exa recurring search results. Its contract is a query, result count, interval, webhook, run history, and one-time signing secret.
Use monitor.site.* for Firecrawl page, crawl, or web-search change checks. Its contract includes typed targets, a cron or natural-language schedule, retention, optional goal-based judging, page-level diffs, Firecrawl credit estimates, and optional webhook events.

Ask one focused question if the intended contract is unclear.

Readiness and ownership

Run arks --version. If unavailable, explain that ArkSpace CLI is required and ask before changing the user's environment.
Run arks doctor --json when Provider readiness is unknown. If credentials are missing, direct the human to run arks setup in a trusted local terminal. Never ask for an API key in conversation or place one in a command argument.
Ask before changing configuration or the user's environment. Use only ArkSpace-owned monitor IDs; every resource is bound to the anonymous key ID that created it.

Create an Exa recurring search

Before creation, present the monitor name, exact query, result count, cadence, public HTTPS webhook, new secret-file path, and continuing charges. Obtain explicit approval, then call monitor.create with confirmed: true.

The secret path must not already exist. ArkSpace creates it with restrictive permissions and never returns the secret. Configure the receiver to verify Exa-Signature. Do not copy the secret into chat.

Create a Firecrawl site monitor

Before creation, present:

the exact scrape, crawl, or search targets;
the five-field cron or natural-language schedule and IANA timezone;
retention from 1–365 days;
the judging goal and whether judging is enabled;
the public HTTPS webhook and selected monitor.page or monitor.check.completed events, if any;
Firecrawl's estimate when available, and that each check bills underlying scrape, crawl, search, and optional judging work.

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.

monitor is a skill published in the GitHub repository arch3rPro/Ark-Space (0 stars, last pushed 3d ago), licensed MIT. It adds 56 tokens to every session and 964 once invoked, about $0.0003 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 2026-09-10.
