What it can do

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.

• cromanion_open_claim

  Start here, and you need nothing to do it — no API key, no human. This call takes no credential and creates NOTHING: no account, no key, no charge. It returns a challenge to publish on the site you manage (a file, a meta tag or a DNS record — whichever your hosting lets you write

• cromanion_verify_claim

  Redeem a claim once you have published one of its three proofs (a /.well-known file, a tag, or a DNS TXT record). On success it creates the account and the site and returns the tracking snippet to install. Idempotent — safe to retry. Requires the claim secret as a bearer token.

• cromanion_site_status

  Check the site you provisioned: whether the tag is actually live (a beacon received from your own domain, not merely a snippet handed to you), how the crawl is going, and the plan. Poll this after installing the snippet. Requires the claim secret as a bearer token.

• cromanion_install_check

  Why the tag is not firing. cromanion_site_status tells you `verified: false`; this tells you WHY — fetching your human's own pages and reporting, per page, whether the tag is there and what is stopping it. It finds the four failures a boolean cannot: the tag missing from some pag

• cromanion_upgrade_link

  Get a Stripe Checkout link for a paid plan (pro or growth). Returns a URL and nothing else — YOU do not pay and cannot: give the link to your human, who enters their own card. The site works on the free plan meanwhile. Requires the claim secret as a bearer token.

• cromanion_errors

  Every refusal this server can return, and what to do about each. Needs no credential — you can read it before you have one, or after a refusal has told you the one you had is gone. The field to branch on is `retry`: `later` means a cooldown or a transient, `fix_request` means cha

• cromanion_grants

  List what your human has allowed this agent to do, and what they have not. Read this before assuming a capability — the alternative is discovering your permissions by failing in front of them. You cannot change these yourself; only your human can, in their console.

• cromanion_pending

  Everything on this site that is waiting for a decision: page rewrites the agent wants to make, rules it distilled from real sessions, conversions it spotted but has never counted, and pages your traffic found that the crawl missed. This is the client's actual job in the console,

• cromanion_config

  Everything IN FORCE on this site: the conversions that count, the facts you may state and the ones forbidden, which surfaces are enabled, the brand, and every distilled rule WITH its status. cromanion_pending shows what is waiting for a decision; this shows what was already decid

• cromanion_decide

  Rule on one thing from cromanion_pending: pass its `kind` and `id` back unchanged with a decision. `approve` / `reject` for everything; `pause` additionally for a playbook rule. Approving a GOAL is different in kind from the rest — it changes what every impact figure for this sit

• cromanion_set_playbook

  Reword a distilled rule, or ask for a fresh distillation. Rules are what the agent learned from real sessions; cromanion_decide approves or pauses them, and this changes what they SAY. Send a ruleId with condition and/or recommendedAction to reword one — ids come from cromanion_c

• cromanion_ask_human

  Ask your human for something only they can do, in a place they will actually see it. Every other refusal here ends with YOU reading it — a permission they did not grant, a payment you cannot make, a mode you may not set — and from their side you simply went quiet. This puts one r

• cromanion_mark_read

  Mark notifications read once you have passed them on to your human. cromanion_pending returns the unread ones and nothing cleared them, so the queue grew for ever and you re-read the same items on every poll. Send a notificationId for one, or nothing to clear them all. Needs the

• cromanion_impact

  What the agent has actually changed: visitors who saw it versus the 10% held back as a control. Read `liftStatus` before reporting anything — `learn` means nothing has been shown yet and `insufficient` means the arms are too small to tell signal from noise. Neither is 'no lift'.

• cromanion_visits

  List your human's recent visits — each with its pages, how it ended, what Cromanion's agent showed or held back, the doubts it read, and the start of the visit's story. Filter by page, outcome, doubt, device, channel and more; page through with `next`. Needs the visits permission

• cromanion_visit

  One visit in full: the story of each page load, every moment Cromanion's agent looked at the visitor and what it decided, what the visitor actually saw, and the doubts it read. Pass the `visitId` from cromanion_visits, or a `sessionId` from cromanion_live once that visitor has le

• cromanion_live

  Who is on your human's site right now: each visitor's pages so far, what the agent showed them, and its current reading of them. Paid plans only (Pro and up) — on Free it is refused with the way to upgrade. Needs the visits permission. Poll at most once a minute; this has its own

• cromanion_set_mode

  Switch the agent on. `learn` watches and shows visitors nothing; `act` lets it intervene in your human's name. `customizeMode` is a separate axis for rewriting their own page copy: `off`, `shadow` (propose only) or `live`. Needs the activation permission.

• cromanion_add_goal

  Define a conversion to count, or change one you already defined. This is not one more setting: it is the numerator of every impact figure your human will read, so a goal that fires on every pageview makes the agent look brilliant and tells them nothing. Send `type` and `value` to

• cromanion_crawl

  Re-read the site, and name the pages that matter most so they are read first. You know this site's structure better than its owner does — seeding it is the cheapest real improvement to what the agent understands. Rate-limited: one crawl per 30 minutes. Needs the site-config permi

• cromanion_add_site

  Add another of your human's sites to their account, on a plan that allows more than one. Reaching a site they already own needs no proof — they added it. CREATING one does: nothing about holding a credential for one domain says anything about another, so publish this claim's chal

• cromanion_claim_domain

  Claim another host for this site so its traffic counts, or give one up with `remove: true`. A DIFFERENT registrable domain must be proven on its own — publish this claim's challenge there too, then call again. Subdomains need no call at all: a claimed domain already covers them.

• cromanion_set_voice

  Write the facts the agent may state to visitors, and the things it must never say. Plain sentences, one idea per line; start a line with 'never' to forbid something. Anything you write that your human's own pages do not already state is attributed to THEM as the source — so write

• cromanion_set_surfaces

  Choose where the agent may speak and what those places look like: which layout surfaces are enabled, whether the exit modal is allowed, custom CSS, and per-surface HTML. Markup and CSS are re-checked against an allowlist on every visitor — anything that could run, or fetch a remo

• cromanion_set_holdout

  Set the share of visitors held back from the agent so its effect stays measurable (0.05–0.5). Changing it splits the measurement window: periods either side are compared separately and never pooled. Needs the measurement permission.

• cromanion_set_exclusions

  Put an excluded device back into the measurement. Your human can mark their own devices as "not a real visitor" so their browsing does not count; this removes one of those marks, by the label they gave it. You cannot ADD an exclusion — that names the caller's own browser, which y

• cromanion_set_brand

  Adjust the palette, fonts and button styling the agent paints its surfaces with. The crawl guesses these from a stylesheet; you probably know the real tokens. Cosmetic only — it changes how the agent looks, never what it may say. Needs the brand permission.

• cromanion_set_lead_destination

  Set where captured leads are delivered: an https webhook, a connected HubSpot portal, or off. Note before you use it: this is the one change that leaves no other trace — forms keep working and visitors keep being thanked while the addresses go somewhere new — so every change emai

• cromanion_disconnect_hubspot

  Sever the account's HubSpot connection. The other half of cromanion_set_lead_destination's `hubspot` option: you can point leads at a CRM, so you can take them back out. Refused while any site on the account still delivers there — change those destinations first, or the forms wou
