inkbox-onboarding

inkbox-onboarding is a skill for Claude Code from inkbox-ai/inkbox. It costs 46 tokens per session (1,725 once invoked), scanned A, original, MIT.

A setup workflow for an existing Inkbox identity, where Inkbox provides software agents with communication channels such as email, SMS, iMessage, and calls. It also covers inbound message handling and recurring conversation checks after an API key exists.

In plain words
What is it for?
Use it to inspect an identity, prepare requested communication channels, provision or configure them with confirmation, test each channel, set up inbound handling, and plan recurring inbox or conversation triage.
Why use it?
It prevents assuming that one working channel means all requested channels are ready. It also adds consent checks, bounded tests, delivery verification, and a deliberate choice between polling and signed webhooks for incoming events.

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.

Security

Grade A, and why

inkbox-onboarding scanned grade A with 1 finding 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 10d 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.

Inkbox Onboarding

Use this skill after an API key exists. If the agent still needs an account or API key, use inkbox-agent-self-signup first.

Onboarding Process

  1. Confirm which Inkbox API key and identity should be used. Never print, log, or commit the key.
  2. Inspect the authenticated principal and current identities before creating or changing anything.
  3. Check each requested channel independently. A working mailbox does not imply that SMS, calls, or iMessage are ready.
  4. Ask before provisioning a number, enabling a channel, changing inbound routing, creating a webhook, or sending test traffic.
  5. Complete any recipient-side connection or consent step.
  6. Run one bounded test per requested channel and verify the resulting record or reply instead of assuming an accepted request was delivered.
  7. Choose an inbound strategy: polling for simple agents, signed webhooks for event-driven agents, or both.
  8. Offer recurring inbox and conversation triage only after the channels are ready. Confirm cadence, channels, identities, and whether replies are allowed.

Readiness Checklist

Channel Ready when Recipient-side step
Email The identity has a mailbox None
SMS/MMS The identity has a local phone number and its SMS status is ready The recipient must text START before the first outbound message
Calls The identity has a phone number, or a supported connected shared iMessage line is selected for the call Shared-line calls require an existing iMessage connection
iMessage, shared service iMessage is enabled for the identity The person texts the runtime-provided connect @handle command to the current router number
iMessage, dedicated line iMessage is enabled and a dedicated line is attached Server-side contact policy must allow the send

Identity creation provisions a mailbox and tunnel together. A phone number is optional and must be local; do not request a toll-free number. New local numbers can remain pending while messaging registration completes, so inspect sms_status and wait for ready rather than retrying sends.
