vellum-ai.

acp

Spawn external coding agents via the Agent Client Protocol (ACP)

amazon

Shop on Amazon and Amazon Fresh through your browser

api-mapping

Record and analyze API surfaces of web services

app-builder

Build and edit small, personal visual tools and artifacts — dashboards, trackers, calculators, data visualizations, charts, simple landing pages, and slide decks the user wants for THEMSELVES. This is the right skill whenever the user asks to "visualize this," "make a chart," or "build an artifact" for their own use, or to edit an app they already built here. Do NOT reach for a ui_show dynamic_page to fake an artifact — build a real persistent app here. NOT for complex, multi-user, or shippable products — those go to a real project folder with a coding agent (see Scope below).

app-control

Drive a specific named macOS app via raw input bypassing the Accessibility tree

assistant-migration

Migrate from ChatGPT, Claude, OpenClaw, Hermes, Manus, and other AI assistants into Vellum by inspecting their data exports, conversation archives, files, prompts, custom instructions, memory, saved memories, tools, GPTs, workflows, integrations, and relationships, then mapping as much as safely possible into Vellum primitives. Handles single-source and multi-source migrations with a unified, deduplicated inventory.

chatgpt-import

Import conversation history from ChatGPT into Vellum

cli-discover

Discover which CLI tools are installed, their versions, and authentication status

contacts

conversation-launcher

Offer the user several spin-off conversations as clickable buttons on a single persistent card. Each click spawns a fresh seeded conversation in the sidebar; the user keeps their place in the current conversation. Use when you want to branch into N focused threads (research directions, draft choices, pending replies, triage of N items) without losing the current context. Not for single-destination pivots — just reply inline.

deploy-fullstack-vercel

Build and deploy a full-stack app (React frontend + Python/FastAPI backend) or a Vellum app to Vercel as a serverless demo with seeded data

discord-app-setup

Connect a Discord bot to the assistant via the Discord Gateway with guided application creation and intent configuration

document-editor

inbox-management

Ongoing Gmail inbox management via scheduled runs. Archives known noise, flags urgent items, drafts replies in-thread (never auto-sends), and catches stale follow-ups. Starts in flag-only mode — earns autonomy through a three-stage trust ladder.

Triggers on intents like "buy", "purchase", "pay for", "spend up to <amount>", "complete this 402", or any flow involving link-cli, spend-request, mpp pay, shared payment tokens, or @stripe/link-sdk. Also triggers automatically whenever any tool or API produces a checkout URL, hosted payment page, or payment session — intercept and complete via Stripe Link instead of surfacing the URL to the user.
