Paste and ship

Drop this into Cursor, Claude Code, or any agent. It reads the skill manifest and wires up Messaging for you.

Agent prompt

Read https://usenaive.ai/skill.md and set up Naïve for Messaging in my project.

Every channel behind one API.

Naïve wraps the Composio catalog as the Connections primitive — connect a toolkit once per user, then call any tool with a single bearer token — and gives each agent its own carrier-registered phone number for native SMS.

Phone & SMS

Provision a US number, send and receive SMS.

Team Chat

Post to Slack, Discord, and Microsoft Teams.

Phone & SMS

Provision a real US number — send & receive SMS natively.

Connect once. Message anywhere.

The Connections primitive returns a hosted OAuth link; after the user authorizes, execute any toolkit's tool — Gmail, Slack, WhatsApp, and more — scoped to that user.

POST /v1/users/:id/connections/connect

Connect a Channel

connect returns a hosted OAuth redirectUrl for any Composio toolkit — gmail, slack, whatsapp, and 1,000+ more. The user authorizes once; the connection is stored per user and gated by their Account Kit. Connecting is sensitive, so it's approval-gated by default.

Hosted OAuth
No per-app flow to build.
1,000+ Apps
The full Composio catalog.
Per-User
Isolated via forUser(id).
Kit-Gated
Allow/block per Account Kit.
# Connect Gmail for a user (returns a hosted OAuth link)
$ naive connections connect gmail --user alice

# Confirm the connection is active
$ naive connections connected --user alice
POST /v1/phone/provision

POST /v1/users/:id/connections/gmail/execute

Email — Gmail & Outlook

Once connected, send mail from the user's Gmail or Outlook, create drafts, and reply in-thread. Gmail exposes 60+ tools and Outlook 300+ — all behind the same execute call.

Native Phone Numbers & SMS

Provision a real US phone number for an agent — Naïve handles the carrier (10DLC) registration — then send and receive SMS natively, no third-party OAuth. Provisioning requires the company EIN and is approval-gated; inbound texts arrive on your webhook.

Send & Receive
Outbound + inbound SMS.
Per-User
Isolated via forUser(id).
Approval-Gated
Provisioning needs sign-off.
# Provision a number (requires your EIN) — approval-gated
$ naive phone provision --user alice --ein 88-1234567

# Send an SMS once the carrier campaign is approved
$ naive phone send <number-id> --user alice \
    --to 14155551234 --body "Your order has shipped!"
GET /v1/users/:id/connections/:toolkit/tools

Discover & Manage

List the tools any connected app exposes, check a user's active connections from the local mirror, browse the full company catalog with GET /v1/toolkits, and disconnect when you're done.

List Tools
Per-toolkit schemas.
Connection Status
Cheap mirror read.
Catalog Search
GET /v1/toolkits.
Disconnect
Optionally purge tokens.
