simpler.directoryDISCOVERY TIER 1 of 3 — the service directory: one token-dense line per service (s:name st:status cost:class ops:N — purpose). START HERE instead of reading every tool. No auth required. NEXT: simpler.describe_service with a service name from the listing.
simpler.describe_serviceDISCOVERY TIER 2 of 3 — one service's operations and entity shapes from the live catalog, token-dense (op lines name the underlying tool). No auth required. NEXT: simpler.invoke {service, operation, args} — or call the named tool directly.
simpler.invokeDISCOVERY TIER 3 of 3 — execute one operation: dispatches to the underlying generated tool (same gates, same envelope, same idempotency as calling it directly). Requires auth. args = the underlying tool's arguments object.
simpler.outcomesDISCOVERY TIER 0 — the OUTCOME MENU: one line per common business outcome, each mapped to ONE tool with one-call notes (composites: ONE call creates the whole document). START HERE for a business task. No auth required. NEXT: call the named tool directly, or simpler.directory fo…
simpler.approval_statusCheck a parked approval by approval_id (returned in an APPROVAL_REQUIRED refusal). States: pending (the account owner has not decided — tell the user, do NOT retry the original call), executed (done — the result rides this response; never re-run the call; an approved invoice_sha…
agent_note_send_cross_tenantSend a cross-tenant AI-to-AI message into another tenant's agent_note inbox — the door that turns a cross_tenant_comm consent grant into an actual reach. Both tenants must be KYB-approved and the recipient must hold an active grant (claims can narrow it further); every recipient…
contact_upsertCreate-or-merge a contact keyed on email-then-phone identity — the sync door the future desktop harness and ingest lanes write through. Matching probes email first, then phone; a hit MERGES only the fields you send (omitted fields keep their stored values, so a partial sync payl…
expense_createLogs a new expense — amount_cents must be integer CENTS (a decimal string via `amount` also works, and `category` resolves to a category_id by name). A same-amount, same-UTC-day duplicate for the same user is refused as CONFLICT unless you resend identically with force: true. St…
expense_submitSends your own draft expense into the approval queue — draft only; an already-submitted or resolved expense refuses CONFLICT, and only the expense's own creator may submit it. Nobody is notified automatically — approvers see it appear in the Team Claims view. NEXT: expense_appro…
expense_approveApproves a submitted expense claim — requires the admin or owner role, and only a 'pending' expense qualifies (CONFLICT otherwise). Stamps approved_by and approved_at with the caller and the current time; once approved, the row's content freezes for everyone except the approver…
interaction_createLog an interaction — call, meeting, email, message, visit, payment, or other — against a contact. The ONE activity-logging door every lane funnels through, so the contact's last_contact_at freshness bumps no matter which surface logged the touch; the bump never moves backward, s…
invoice_createONE call creates the whole document: client_name + `items` [{description, quantity, unit_price}], each price as written ("5000.00"). It claims the next invoice number and writes every line; client_name finds or creates the client. A 'paid' birth needs items in the same call. tax…
invoice_adjustment_record[REQUIRES APPROVAL] Records a credit note, write-off or post-issue discount on an issued invoice. A credit_note is numbered from the credit note series, holds its tax at the invoice's rate and takes reason_code and credit_outcome: reduce_balance (default) lowers what is owed; re…
invoice_payment_recordRecords a money-in fact row against an invoice (by invoice_id or its invoice_number) in ONE call: money is integer CENTS via amount_cents, or a decimal STRING via amount — never multiply or divide yourself. A draft invoice auto-advances to 'sent'; a cancelled invoice refuses; an…
myinvois_invoice_generateMint a sealed LHDN e-invoice in ONE call: invoice_type, line_items (unit_price_cents in integer CENTS, tax_rate_bps in basis points), and a buyer as customer_id or an inline buyer object. Refuses until myinvois_settings_save is done; invoice_type 02/03/04 also needs original_inv…
myinvois_invoice_record_submissionRecord the UUID the LHDN MyInvois portal assigned after the owner keyed this e-invoice into the portal (its form or LHDN's Excel batch template). Simpler never submits to LHDN and never calls the MyInvois API; this only stores the UUID the owner copies back. Only a type-01 origi…
myinvois_invoice_readRead one sealed e-invoice by id, with its portal_field_sheet: the document's values laid out to key into the LHDN MyInvois portal form (e-invoice details, supplier, buyer, each line, totals), coded values with their meaning. Simpler never submits to LHDN; portal_field_sheet.port…
quote_createONE call creates the whole document: client_name + `items` [{description, quantity, unit_price}], each price as written ("5000.00"). It claims the next atomic quote number and writes every line together; client_name finds or creates the client. tax_scheme sg_gst or my_sst taxes…
quote_convertConverts a quote into its invoice in ONE call: claims the quote's 'converted' status first (so a lost race never creates an orphan invoice), copies every live line item across, and records converted_invoice_id — nothing else to do afterward. Refuses if the quote is already conve…
settlement_proposal_propose_cross_tenantRecord a payment obligation against a KYB-verified partner tenant's settlement_proposals — the record-don't-move on-ramp: this writes the row only, no money moves until a later settlement-rails door executes it. amount_cents is a nonzero integer CENTS (positive = you owe them, n…
sticky_note_createCreate a sticky_note.
stock_item_adjustMove stock in or out by id or item name, in one atomic write with its movements-ledger row: stock-out clamps at zero (never negative) and applied_quantity reports what actually moved. An unmatched name CREATES the item at quantity 0 first so the delivery still lands as an audite…
team_assignment_create[REQUIRES APPROVAL] Delegates a task to a teammate (or yourself) as a new team_assignment; status is workflow-owned and always starts 'pending' — passing status yourself fails validation instead of being silently overridden. Accepts natural language for the common fields: task_n…
workflow_createCreate a workflow — an AI operator's job: validates definition_json (a { nodes, edges, schedule? } graph) against the platform's node vocabulary, refusing unknown node types and any comms/message-shaped step that isn't a prepare_output node, since the platform prepares outputs b…
workflow_prepared_outputsList this tenant's APPROVED prepared outputs: drafts a workflow's prepare_output nodes parked for review, which a human then approved in the platform inbox. Pending and rejected drafts never appear here — approval happens only in the inbox, never through this call. Optional limi…
ai.budgetYour prepaid wallet, period spend, caps, and runway as a compact line DSL (~8 lines). Requires auth (your balance is closed data). Read this BEFORE committing paid actions; pair with ai.estimate_cost to price a specific call first.
ai.estimate_costPrice an AI task BEFORE running it: provider passthrough at wholesale cost, no markup — the per-token platform fee is retired, so text/reasoning passes through at cost. Anonymous — open catalog includes open pricing. Returns integer micro-USD plus a USD total. NEXT: run the acti…
sales_receivablesWho owes you, by client: each client's unpaid balance aged by days past its due date — current (not yet due), 1-30, 31-60, 61-90 and over 90 days — counted in the business's own days (the sales_settings time zone), so an invoice due today is still current. Only issued invoices w…
sales_document_showShow one invoice, quote or receipt as the document itself. When the result has a second content block, it is the document as copy-ready plain text (title, business, billed to, dates, one line per item, the totals as printed, notes, payment terms and details, or on a receipt the…
invoice_message_preparePrepare what a business sends a client about one issued invoice: purpose 'invoice', 'reminder' (overdue), 'receipt' (paid in full) or 'promise_follow_up' (promised date passed); left out, the one that fits. language 'en', 'ms' or 'zh'; left out, the client's (invoice_client_upda…
invoice_reminders_dueToday's collection list, in the business's days (its sales_settings time zone). reminders: each issued invoice still owed that is 3 days before its due date, on it, or 7 or 14 days after, as its client's reminder_cadence allows (standard, from_due, overdue_only or off; set it wi…
statement_prepareA client's statement of account over a period of the business's own days (the sales_settings time zone): the balance they owed before it (opening), each invoice issued, payment received, credit and write-off in it with a running balance, the balance at its end (closing), and wha…
invoice_handoffGet one issued invoice ready to give the client, in one call: the document, the client link (made if it has none), the PDF (printed or the stored one) and the prepared message (invoice_message_prepare's words, with the link). ready lists the parts made; missing gives each other…
forecast.runWHAT-IF / scenario lane: runs monthly data YOU supply through a seeded 5,000-path simulation of monthly revenue and costs; bands are simulation outputs, not calibrated probabilities. The paths are clustered into 3-7 outcome bands for the next 6 months, with per-month revenue and…
forecast.run_storedRun the tenant's REAL forecast from the books — cash receipts (recorded invoice payments by payment date, plus paid invoices with no recorded payment at their paid date, flagged) and expenses by expense date, monthly in the tenant's base currency, up to the last complete month (…
forecast.readRead the tenant's STORED forecast — the verify-read for this rail. view picks the answer, one of summary, monthly, variance, scenarios, weekly (default summary). summary: the outcome bands (label, growth_direction, probability_pct, final_month_revenue_low and _high, distress_ris…
image.generate[paid: $0.06/image max] Generate 1-3 images from a text prompt on the first lane that delivers, tried in order: google/nano-banana-2.1 via the Cloudflare AI catalog ($0.06/image), then @cf/black-forest-labs/flux-2-dev via Cloudflare Workers AI, only when the first lane is down (…
document.extractFetch a document from a URL, classify its type (personal/medical/business/unknown) with keyword + PII-pattern heuristics (documents containing actual PII data are NEVER business), and return extracted text capped at 100K chars. Free. STREAMING SUPPORTED: send Accept: text/event-…
template.listFree. The media templates: product-shot (product shot), product-lifestyle (product in a real place), poster (promo poster), showcase-video (product video), explainer-voice (voice-over with captions), brand-mockup (brand mockups). Each entry says what it makes, what it delivers,…
spreadsheet.create_with_contentCreate a spreadsheet in the user's library from CSV content in ONE call: the platform stores the bytes (honest text/csv) and registers the file row. Free — storage costs nothing; only AI lanes bill. Returns the file row including its id. Refuses: VALIDATION_ERROR when title or c…
agent_note_mark_readConfirm receipt of a note in your cross-tenant agent_note inbox — the ONLY edit a recipient holds, moving status unread to read under the registry's transition guard. Idempotent: re-confirming an already-read note is a no-op, and the subject/body stay fixed forever so a recipien…
agent_note_listList your agent_note rows (newest first).
agent_note_readRead one agent_note by id.
brand_assets_readRead one brand_assets by id.
brand_assets_listList your brand_assets rows (newest first).
consent_grant_listList your consent_grant rows (newest first).
consent_grant_readRead one consent_grant by id.
contact_createCreate a contact and, in the same call, log its first note and/or first interaction — the composite first-touch door. Children validate before the contact write; if the contact commits but a child then fails, the error names the contact's id plus the exact call to finish it, nev…
contact_updateUpdate a contact you own (optionally compare-and-set via expected_updated_at).
contact_deleteDelete a contact you own.
contact_readRead one contact by id.
contact_listList your contact rows (newest first).
contact_searchSearch your contact rows by text.
contact_note_createAdd a note to a contact — the same door as the granular tool, extended only to accept contact_name, contact_email or contact_phone in place of contact_id. A name match must be unique: more than one hit refuses, listing the candidate ids; zero matches on every alias refuses with…
contact_note_listList your contact_note rows (newest first).
contact_note_readRead one contact_note by id.
contact_note_deleteDelete a contact_note you own.
desk_surface_createPins one widget or a saved artifact onto the operator's home canvas. kind='widget' requires widget_key from the shipped enum; kind='artifact' requires content_ref (an assistant artifact id) — the door enforces whichever pair the kind demands, since the schema alone cannot expres…
desk_surface_updateMoves, resizes, or restacks a surface already on the desk canvas — x/y/w/h/z_index are real column writes, not a layout cache. The surface's identity is frozen here: kind, widget_key, and content_ref never change through this door, only via delete then re-create. NEXT: desk_surf…
desk_surface_readRead one desk_surface by id.
desk_surface_listList your desk_surface rows (newest first).
desk_surface_deleteDelete a desk_surface you own.
edit_project_createCreate a canvas project from a Fabric.js toJSON serialization (canvas_json, required): every embedded data:image src is pulled out, hashed, and written to a tenant-scoped, content-addressed R2 key before the row is saved, so canvas_json never carries image bytes and identical im…
edit_project_updateSave changes to an existing canvas project by id — the autosave door: send only the fields that changed (name, canvas_json, width, height, thumbnail_data_url), everything else on the row is left alone. A canvas_json you send goes through the same image-externalization and hygien…
edit_project_readRead one edit_project by id.
edit_project_listList your edit_project rows (newest first).
edit_project_deleteDelete a edit_project you own.
expense_updateEdits an expense's own fields only — status and approval stamps refuse with VALIDATION_ERROR here since those are transitions (expense_submit, expense_approve, expense_reject, expense_reimburse). amount_cents, if changed, must stay integer CENTS. Only the expense's own creator m…
expense_deleteDeletes an expense you created — draft and rejected rows only. Pending, approved, and reimbursed rows are approval-trail records and refuse with CONFLICT (approval_locked: true), and the lock is pinned into the delete itself so a status change racing your read still refuses inst…
expense_rejectRejects a submitted expense claim — requires the admin or owner role, and only a 'pending' expense qualifies (CONFLICT otherwise). rejection_reason (up to 500 chars) is optional but records why; rejected is terminal and never counts as spend, so a corrected claim is a fresh expe…
expense_reimburseMarks an approved expense as paid out — restricted to the tenant owner because it moves real money, and only an 'approved' expense qualifies (CONFLICT otherwise). Stamps reimbursed_at, after which the row's content freezes unconditionally since the amount approved is the amount…
expense_readRead one expense by id.
expense_listList your expense rows (newest first).
expense_searchSearch your expense rows by text.
expense_aggregateAggregate (count/sum) over your expense rows.
expense_budget_createCreate a expense_budget.
expense_budget_updateUpdate a expense_budget you own (optionally compare-and-set via expected_updated_at).
expense_budget_deleteDelete a expense_budget you own.
expense_budget_readRead one expense_budget by id.
expense_budget_listList your expense_budget rows (newest first).
