Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (32)

`accept_invitation`	Accept a pending invitation and grant the invitee's first role assignment. Call this when an invitee has a valid invite link and wants to join the tenant; single-use, consuming the token marks it accepted.
`add_tenant_service`	Request a new service subscription for the caller's tenant and return its status. Call this when a tenant admin wants to add a service (ADR 0016 code fix: requires `admin`, was `customer` realm role only).
`approve_access_request`	Approve a pending access request: issue a `member` invitation to the requester and resolve the request (level `admin` or `owner` of the request's tenant). The response carries the single-use invitation token to hand to the requester, who accepts via `accept_invitation`. 409 `access_request.not_pending` unless the request is pending.
`complete_billing`	Complete the tenant's billing details: legal-entity name and type, VAT id, invoice address, invoice email and optional PO reference. Call this when the owner or a billing contact has the details. EU VAT ids are validated against VIES by the worker; a failed operation with `billing.vat_check_unavailable` can be retried by submitting again. Returns `202` with an operation to poll.
`create_access_request`	Request access to the tenant that owns the caller's verified email domain.
`create_invitation`	Invite an email address to the caller's tenant at the specified access level and return the invitation, including the raw single-use accept token. Call this when a tenant admin wants to add a new member; the invitee accepts via `accept_invitation`.
`create_self_service_tenant`	Create a 7-day trial tenant for the caller's business email domain (UC-052). Needs a verified email on a business domain and `attestation: true`; answers `auth.email_not_verified`, `tenant.attestation_required`, `tenant.free_mail_domain` (free-mail address), `tenant.domain_exists` (a live trial tenant on the domain) or `trial.exists_for_domain` (the domain already had its one trial; call `start_inquiry`). The trial lasts exactly 7 days; `ttl` / `expires_at` in the body are ignored.
`dismiss_access_request`destructive	Dismiss a pending access request (level `admin` or `owner` of the request's tenant). The requester is mailed — naming the tenant, never the dismissing admin — and may ask again. 409 `access_request.not_pending` unless the request is pending.
`enrich_domain`	Fetch the caller's domain imprint and suggest legal-entity details (UC-057).
`get_billing`read-only	Return the tenant's stored billing details: VAT id, invoice address, invoice email and PO reference. Call this to check whether billing is complete; only the owner and billing contacts may read it (`403 rbac.insufficient_level`).
`get_catalog_templates`read-only	Return the enabled ApplicationTemplate catalog, ordered by name. Call this to discuss trial and template options with a prospect or customer before starting a trial. If this doesn't answer your question, call `start_inquiry` to ask 4chems directly or request a call.
`get_legal_entity_types`read-only	Return the legal-entity types available for country, ordered alphabetically. If this doesn't answer your question, call `start_inquiry` to ask 4chems directly or request a call.
`get_my_access`read-only	Return the caller's access level per related tenant. Call this to check what the current caller is authorized to do before attempting an action that requires a specific level, or to discover a pending invitation or access request.
`get_my_operation`read-only	Return the status, result and error of an operation the caller started, such as the `Location` of a `202` from `complete_billing`. Call this to poll it to completion.
`get_onboarding_route`read-only	Return the next onboarding step. If this doesn't answer your question, call `start_inquiry` to ask 4chems directly or request a call.
`grant_assignment`	Grant a role x scope assignment to a tenant member.
`list_consents`read-only	Return the caller's own recorded consents plus the tenant-scope consents of every tenant where the caller is at least a viewer. Call this to check which legal documents have already been accepted before asking again. Pass `tenant_id` to list one tenant's consents only (a caller of several tenants must).
`list_invitations`read-only	List all invitations for the caller's tenant, most recent first. Call this to show a tenant admin which invitations are pending, accepted, or revoked; the raw token is never included.
`list_members`read-only	List tenant members with their effective role x scope assignments.
`list_tenant_services`read-only	Return the caller's tenant's active service subscriptions. Call this before offering to add a service, to check what is already subscribed.
`record_consent`	Record acceptance of a legal document version and return the entry; call this only after showing the user the document URL and version and receiving an explicit affirmative answer.
`revoke_assignment`destructive	Revoke a role x scope assignment from a tenant member.
`revoke_invitation`destructive	Revoke a pending invitation so its token can no longer be accepted. Call this when a tenant admin wants to withdraw an invite sent by mistake or no longer needed; accepted invitations cannot be revoked.
`start_account_registration`	Start registering a 4chems account with a business email address (`email`, `name`, optional `company`). Anonymous. Emails a 6-digit code to the address; no account exists yet. Ask the user for the code, then call verify_account_registration with the returned challenge_id and code. Free-mail addresses (gmail.com, ...) are refused: use the company address, or call start_inquiry. The answer is the same whether or not the address already has an account.
`start_device_login`	Sign in to an existing account by device login (UC-091, RFC 8628). Anonymous, empty body; the account must exist (start_account_registration, then set the password through the emailed link). Show `verification_uri` (or `verification_uri_complete`) and `user_code` to the human, who signs in there, then call `verify_device_login` with `challenge_id`, waiting `interval` seconds between calls. The response never contains the Keycloak device_code or the agent client secret.
`start_inquiry`	Store an anonymous inquiry draft and email a 6-digit verification code. Ask the user for the code, then call verify_inquiry with the returned challenge_id and code — the inquiry reaches 4chems only after that verification succeeds.
`start_registration`	DEPRECATED: use start_device_login. Deprecated — use start_device_login (same behaviour).
`verify_account_registration`	Verify the emailed 6-digit code (`challenge_id`, `code`) and create the 4chems account. Never guess or retry codes, and never ask the user for a password.
`verify_device_login`	Poll a device login to token issuance (UC-091, RFC 8628). Anonymous. While the human has not signed in yet it answers `{"status": "pending", "retry_after": <seconds>}`: wait `retry_after` seconds and call again with the same `challenge_id`. On approval it returns Keycloak's token set (`access_token`, `refresh_token`, `expires_in`, ...) exactly once; pass the `access_token` as `authorization` ('Bearer <token>') to every other tool.
`verify_inquiry`	Verify the 6-digit code and deliver the inquiry to the helpdesk inbox.
`verify_registration`	DEPRECATED: use verify_device_login. Deprecated — use verify_device_login (same behaviour).
`withdraw_access_request`destructive	Withdraw the caller's own pending access request; no notification is sent. Any other caller gets 404 `access_request.not_found`, the same as for an unknown id. 409 `access_request.not_pending` unless pending.
