What you can do

Once installed, just ask in plain English:

Create a new outbound sales agent for Acme Roofing — friendly, qualifies budget and timeline, books a 15-min discovery call.

Add 500 contacts with a phone number that haven’t been called yet in the Husband Realty account to the AI Reactivation Sequence workflow.

Show me last week’s report for Beta Dental.

The booking agent on Gamma Plumbing keeps failing on price objections. Pull the last 30 calls and tell me what to fix.

What conversations need my attention right now?

Switch me over to Delta Roofing.

Or use slash commands directly when you want a specific, repeatable output format.

The campaign command

The headline feature: /outbox-cli:outbox-campaign is an interactive campaign builder. It filters contacts in the active client (tags, custom fields, last-activity date, has-phone, etc.), previews the matches, and enrolls them into a workflow in batches. Use it for reactivation pushes, follow-up sequences, segment-specific outreach — anything where you’d otherwise be exporting CSVs and importing into the workflow UI.

Get set up (under 2 minutes)

Open a terminal

On Mac, open Terminal (it’s already installed) or download Warp for a nicer experience. On Windows, install Warp or use WSL.

Install Claude Code

If you don’t have it yet, follow the install steps at claude.com/claude-code. Then launch it by typing claude in your terminal.

Run these three commands inside Claude Code

/plugin marketplace add Outbox-Solutions/outbox-claude-plugin
/plugin install outbox-cli@outbox
/outbox-cli:outbox-setup

The setup command walks you through signing in with your Outbox email and password, picking which client to start in (if you’re an agency operator), and gives you a 30-second tour of the most useful commands.That’s it — you’re ready to go.

Slash commands

All commands are namespaced under /outbox-cli: so they won’t collide with Claude Code built-ins or other plugins.

Skills (auto-trigger)

Claude triggers these automatically when you describe what you want — no need to remember a command name.

Skill	Triggers on
`optimize-agent`	”improve this agent”, “calls keep failing”, “audit performance”
`build-report`	”give me a weekly report”, “how did we do this month”, “summarize last week”
`triage-conversations`	”what needs my attention”, “any unread”, “anything stuck”

For agency operators

If your account is an agency account, signing in gives you access to every client company under your agency. Switch between them at any time:

/outbox-cli:outbox-use-client acme

The selection persists across Claude Code restarts and is keyed to your sign-in (so two teammates in the same agency don’t step on each other’s active client).

Recommended workflow

Keep a folder per client on your machine:

~/clients/
  acme/
  beta-dental/
  gamma-plumbing/

cd into a client’s folder before launching Claude Code, then run /outbox-cli:outbox-use-client once to set the context. After that, the client stays active for that session.

Built-in docs lookup

The plugin also wires Claude Code into the official Outbox docs. Ask any “how do I…” or “what does X mean” question and Claude searches the docs automatically.

what’s the difference between an agency key and a company key?

how do I set up a voice mailbox?

what does “concurrent call limit” mean?

Troubleshooting

"You're not signed in" after signing in

Run /reload-plugins inside Claude Code. The plugin needs a quick reload to pick up your fresh sign-in.

"Plugin not found in any marketplace"

Make sure you’re using the qualified install command:

/plugin install outbox-cli@outbox

Not just /plugin install outbox-cli.

Slash commands aren't appearing

Run /reload-plugins once, then type /outbox-cli: and you’ll see the full list in the autocomplete picker.

"Token is invalid" or you keep getting signed out

Your session expired or was revoked. Just run /outbox-cli:outbox-sign-in again to sign back in.

Something else broken?

Open an issue on the plugin repo or ask your Outbox contact.

MCP Server — connect any MCP-compatible client (Claude Desktop, Cursor, etc.)
JavaScript SDK — call the Outbox API from Node and the browser
