# Definable App Catalog — 1000+ integrations the agent workforce can act on

> Definable agents do not just answer. They act. Every integration in this catalog is a tool the Distributor specialist can call inside a multi-agent workflow — schedule a post, push a CRM record, open a PR, send an invoice, sync a calendar. Workflow-grade integrations, included on every plan.

## Why integrations matter inside a multi-agent workflow

A Definable workflow is run by three orchestrating agents — Builder, Executor, Verifier — coordinating a team of specialists (Researcher, Writer, Designer, Engineer, Distributor). The Distributor is the specialist that touches the user's tool stack. Without integrations the agents draft. With integrations the agents ship.

The Builder agent picks the right integrations for each task automatically based on the plain-English prompt. The Executor calls them. The Verifier checks every response, retries on rate limits or schema drift, and self-heals failures.

## Total integrations

**1000** apps available. All connect via OAuth2 or managed auth. Every integration is callable from any workflow on every plan — no per-app limits, no per-task pricing.

## How agents use integrations

In every workflow, the **Distributor specialist** is the agent that talks to the user's tools. The Builder reads the prompt ("Launch a campaign on LinkedIn, X, and Buffer"), identifies the integrations needed (LinkedIn, X, Buffer), and routes execution through the Distributor. The Researcher pulls data via integrations like Notion, Google Drive, and Perplexity. The Engineer commits code via GitHub or GitLab. The Writer pushes drafts into Google Docs or HubSpot. Every specialist that needs to read or write external state does it through this catalog.

The Verifier validates every call. If LinkedIn rate-limits, the Verifier reroutes through Buffer or retries with backoff. If a CRM schema shifts, the Verifier rewrites the payload and retries. The user never sees the failure — only the shipped outcome.
