Skills
get_mailbox

Get your agent's real mailing address beta endpoint when the account has explicit beta access: street address + mailbox number for approved accounts. For generally available inbound context, use list_inbound_forwarding_addresses instead; that returns a private intake alias for scans, PDFs, photos, provider notices, and notes from addresses the operator already uses.

list_packages

List inbound mail or packages for approved real mailing address/package beta accounts with optional filters by status, carrier, and date. Returns tracking number, carrier, status, and received timestamp where available. For generally available inbound postal context, use list_inbound_mail with forwarded scans/PDFs/notes instead.

get_package

Get full package details including photos, tracking events, shipping label data (carrier, addresses, weight), forwarding status, storage location, and action history.

get_package_photos

Get photos for a package with OCR-extracted text and confidence scores. Filter by photo type to get only exterior shots, label closeups, barcode scans, or content scans.

request_action

Request a physical action on a package at the facility. Actions include forwarding to another address, shredding, scanning documents, holding for pickup, disposing, returning to sender, photographing, opening and scanning contents, or recording a video. Some actions (shred, dispose) are irreversible.

request_scan

Request document scanning (OCR + structured data extraction) for a package. The facility will scan the document and extract text, addresses, dates, and other structured data. Results are available via get_scan_results after processing.

get_scan_results

Get document scan results including raw OCR text, structured data fields (addresses, dates, amounts), and confidence scores. Returns empty if scan is still processing.

add_tag

Add a tag/label to a package for categorization and filtering. Tags are free-form strings. Adding the same tag twice is a no-op.

add_note

Add an observation or context note to a package. Notes are visible to the facility operator and the renter. Use for recording decisions, observations, or agent reasoning.

create_rule

Create a standing instruction that auto-triggers actions when incoming packages match conditions. Rules run on every new package and execute the specified action if all conditions match. Use requires_approval to add a human review step before execution.

register_expected

Pre-register an expected inbound shipment so it is auto-matched when it arrives at the facility. Optionally specify an action to auto-execute on arrival (e.g. forward immediately, scan on receipt).

get_usage

Get usage summary and billing events for a time period. Returns itemized events (scans, forwards, mail sends) with costs, plus period totals. Defaults to the current billing period if no dates are specified.

list_inbound_forwarding_addresses

List the renter’s private inbound forwarding aliases on forward.mailbox.bot. These are the unique intake email addresses an operator, assistant, provider, or external agent can forward scans, PDFs, photos, provider notices, notes, and other context-aware documents to so mailbox.bot can build OCR-backed inbound context. Forwarding/emailing attachments here initiates OCR/extraction; this tool discovers the address and does not upload files directly into OCR. The alias is member-scoped, so live and sandbox agent keys for the same member resolve to the same intake address.

list_inbound_mail

List forwarded inbound mail items captured from private forwarding aliases. Default output includes compact draft_context so an LLM or external agent can reason about OCR context, reply contact candidates, deadlines, and thread linkage before generating outbound mail.

get_inbound_mail

Get one forwarded inbound mail item with compact draft_context by default. Use this before drafting an outbound reply when you need sender context, reply contact candidates, deadline clues, source files, and thread linkage in one stable payload.

list_postal_threads

List physical-mail threads that group inbound mail context, human review, and outbound sends. Use this to understand which inbound items and outbound documents belong to the same business workflow.

get_postal_thread

Get one physical-mail thread with optional timeline events. Use this to explain how a generated outbound mail piece relates back to prior inbound scans and review decisions.

update_action

Push notes, structured data, or a clarification response to an existing action request. Use this to add agent reasoning, attach extracted data, or respond when the facility asks for clarification. Requires mailbox_md_version to prove your MAILBOX.md instructions are in sync.

get_mailbox_md

Get the renter's MAILBOX.md standing instructions for this agent. Returns the full instruction text, version number, content hash, and last update timestamp. Call this on startup and cache the version — you must pass it to send_outbound_mail and update_action for sync verification.

propose_mailbox_md_edit

Propose changes to the renter's MAILBOX.md instructions with reasoning. The renter will see your suggestion in their dashboard and can accept, reject, or modify it. Use this when you observe patterns that could be codified into standing instructions.

send_facility_message

Send a message to the facility operator managing your mailbox. Messages appear in the shared conversation visible to you, the renter, and the facility. Optionally link the message to a specific package or action request for context.

list_facility_conversations

List your active facility conversations with unread message counts and last message preview. Each conversation corresponds to one facility where you have a mailbox.

get_facility_messages

Read the message thread with a specific facility. Returns messages in reverse chronological order with sender role (member, facility, agent). Supports cursor-based pagination. Automatically marks facility messages as read.

update_webhook

Configure webhook endpoint URL and event subscriptions for real-time notifications. Events include package.received, package.status_changed, action.completed, mail.status_changed, and more. The endpoint must use HTTPS and respond with 2xx within 10 seconds.

send_outbound_mail

Submit a document for printing and postal mailing by the facility. Supported formats: PDF, DOCX, JPG, PNG, TXT, CSV. The document is stored securely and printed by the facility operator. IMPORTANT: With a production key (sk_agent_), this immediately charges the member's card on file. Use dry_run=true to preview cost before committing, or requires_approval=true to defer until human approval. Sandbox keys (sk_agent_test_) skip billing entirely. Optionally attach the outbound mail to inbound context with inbound_capture_id and postal_mail_thread_id so lineage stays explicit.

list_outbound_mail

List outbound mail jobs with status tracking. Returns mail ID, recipient, mail class, status, cost, and timestamps. Filter by status to see pending, in-transit, or delivered mail.

get_outbound_mail

Get full details of an outbound mail job including recipient address, mail class, page count, cost breakdown, current status, fulfillment photos, and a time-limited signed URL to download the original PDF.

create_test_outbound_mail

Create a sandbox outbound mail record without uploading a real document. The record is always test_mode=true, cost_cents=0, includes estimated_live_cost_cents and cost_breakdown, and queues a mail.submitted webhook. Use with a sandbox key to rehearse outbound workflows before sending real physical mail.

advance_test_outbound_mail

Advance a test_mode outbound mail record one lifecycle step and queue the matching webhook. submitted becomes ready with simulated pages/envelope photos; ready becomes mailed with tracking, carrier, dispatch method, and receipt photo; mailed becomes delivered.
