Verify whether a CAO session is actually alive and what it really

Interact with CAO (CLI Agent Orchestrator) — launch multi-agent sessions,

Supervisor-side orchestration patterns for assign, handoff, and idle inbox delivery in CAO

Worker-side callback and completion rules for assigned and handed-off tasks in CAO

Author and run CAO Python workflow scripts — multi-step, parameterized, fan-out

This skill should be used when the user asks to "add MCP App support to my web app", "turn my web app into a hybrid MCP App", "make my web page work as an MCP App too", "wrap my existing UI as an MCP App", "convert iframe embed to MCP App", "turn my SPA into an MCP App", or needs to add MCP App support to an existing web application while keeping it working standalone. Provides guidance for analyzing existing web apps and creating a hybrid web + MCP App with server-side tool and resource registration.

This skill should be used when the user asks to "create an MCP App", "add a UI to an MCP tool", "build an interactive MCP View", "scaffold an MCP App", or needs guidance on MCP Apps SDK patterns, UI-resource registration, MCP App lifecycle, or host integration. Provides comprehensive guidance for building MCP Apps with interactive UIs.

Load the official MCP Apps builder skills (create-mcp-app, migrate-oai-app, add-app-to-server, convert-web-app) from github.com/modelcontextprotocol/ext-apps. Use when the user says "build an MCP App", "add a ui:// view to my MCP server", "create an interactive MCP App from scratch", "migrate from OpenAI Apps SDK to MCP", or "turn my web app into a hybrid MCP App". Targets the MCP Apps SDK (SEP-1865 ui:// resources) specifically. Not for regular web frontends, REST APIs, CAO provider adapters, SKILL.md authoring, or plugins.

This skill should be used when the user asks to "migrate from OpenAI Apps SDK", "convert OpenAI App to MCP", "port from window.openai", "migrate from skybridge", "convert openai/outputTemplate", or needs guidance on converting OpenAI Apps SDK applications to MCP Apps SDK. Provides step-by-step migration guidance with API mapping tables.

Learning telemetry, strategy, and schedule — retention stats, calibration, grader audit, n-of-1 experiments, HTML dashboard. Use for "how am I doing", weekly check-ins, strategy questions, auditing the grader, or adjusting how Engram teaches.

Learn any topic properly — first-principles curriculum, generation-first tutoring, verified free recall, FSRS scheduling. Use when the user wants to learn, understand, study, or continue studying something.

Clear due memory reviews with free recall — the two-minute habit that makes learning permanent. Use when reviews are due, or the user wants to review, practice, or "do my engram reviews".

Set up, authenticate, and run external coding agents (Claude Code, Codex) via the Agent Client Protocol

Shop on Amazon and Amazon Fresh through your browser

Record and analyze API surfaces of web services

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. A one-off diagram, chart, or explainer that just accompanies an answer belongs to the visualize skill (ui_show visual), not an app. NOT for complex, multi-user, or shippable products — those go to a real project folder with a coding agent (see Scope below).

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

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.

Chat with and search your complex documents — ask questions, extract tables and fields, and get answers grounded in the source. Connects the hosted Unstructured Transform MCP server to parse, structure, and enrich PDFs, Word/Excel/PowerPoint, images, scanned files, emails, and 60+ other formats into clean, AI-ready text for search, Q&A, and summarization without building a custom parsing pipeline.

Control a connected desktop

Manage contacts, communication channels, access control, and invite links

Organize conversations into custom sidebar groups — list groups, create new ones, and file conversations into them

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.

Proactive daily briefing that fires on a recurring schedule, pulls recent memory and workspace context, composes a structured summary (action items, progress, radar, next steps), and delivers it to all active channels. Enable with a time like "set up my daily briefing at 9am". Disable, reschedule, or check status at any time.

Select and tune a Deepgram TTS voice - curated voice list, full Aura voice catalog via API key, and tuning parameters

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

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

Use whenever the user wants to write or draft an article, blog post, essay, report, or any long-form content. Creates the content in a rich text editor instead of dumping it in chat, so it can be streamed, reviewed, edited, and exported.

Order food, groceries, and convenience items from DoorDash using the built-in CLI integration

Select and tune an ElevenLabs TTS voice - curated voice list, custom/cloned voices via API key, and tuning parameters

Set up this assistant's own `[name].vellum.me` domain and email address (one-time setup)

Generate expressive audio clips using Fish Audio S2 TTS with bracket emotion tags. Record voice memos, narration, audio messages, or any spoken content.

Track sent messages awaiting responses across communication channels

Design-quality layer for frontend code — typography, color, motion, spatial composition, and avoiding generic "AI slop" aesthetics. Use this as a companion when you are already writing or styling frontend code and want it to look distinctive and production-grade. For building an app, dashboard, tracker, calculator, visualization, landing page, or slide deck the user wants inside the assistant, load `app-builder` instead — it loads this skill itself for the design pass.

Runs a one-command technical GEO audit on any domain. Checks AI crawler access, llms.txt presence, server-side rendering, sitemap, and schema markup. Streams results live and ends with a 0–100 score plus the top 3 prioritized fixes. Built to be both genuinely useful and great to demo on camera.

Generates GEO/AEO-optimized articles designed to get AI engines (ChatGPT, Perplexity, Claude, Gemini) to cite your brand. Handles research, writing, and file output. Suggests listicle or head-to-head as starting formats if the user is unsure.

Manage Gmail email — drafting, sending, organizing, filters, vacation replies, and inbox analysis

Beta. Act on new Gmail as it arrives: get pinged only for urgent mail, digest newsletters, forward invoices — any standing instruction, across one or several accounts.

View Google Calendar events for any day, create and manage events, and check availability

Set up channel verification for phone, Telegram, Slack, Discord, or email channels via outbound verification flow

Reference guide for running Claude Code in third-party headless, container, and CI environments. Covers auth strategies, interactive mode pitfalls, tmux orchestration, root user workarounds, and git auth without SSH agents or keychains

Create images from a text description, or edit photos and graphics the user provides (remove backgrounds or watermarks, retouch, restyle, in-paint). Can produce multiple variants when the user wants options to choose from.

Run a high-recall, multi-pass email inbox cleanup. Pattern-based subject queries catch 25x more archivable email than sender scans alone. Includes urgency triage, classification signals, and post-cleanup filter setup.

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.

Research influencers on Instagram, TikTok, and X/Twitter through your browser

Create and configure a Linear agent app so the assistant can manage issues, projects, and workflows under its own identity

Analyze and reduce LLM spend: read usage breakdowns by call site, model, and inference profile, understand single-winner profile resolution, and pin call sites to managed profiles (Balanced / Quality / Cost / Speed) only where they should deviate from shipped defaults.

Set up a new LLM provider connection, discover valid model ids, create and validate a model profile — securely and end-to-end via CLI. Covers managed vs BYO keys, secure credential collection, model discovery, profile creation, and live verification.

Automate native macOS apps and system interactions via osascript (AppleScript)

Set up and send emails via a user-provided Mailgun account (BYO email provider)

Add, authenticate, list, and remove MCP (Model Context Protocol) servers — connect any external tool or service that publishes an MCP endpoint to the assistant

Ingest and process media files (video, audio, image)

Join a Google Meet call to take notes; only when the user explicitly asks.

Generate memes from 170+ classic templates using the free Memegen.link API. Search templates, generate captioned images, and download them for posting. No API key required.

Ingest a large dataset into memory as a skimmed map. Cold-store the raw files under a workspace imports directory, census them into a slice plan, skim each slice into compact map pages that point back at the raw files, ingest the map with the memory ingest CLI, and author a drill-in retrieval skill so the corpus stays searchable on demand. For recording archives, transcript collections, document dumps, and any corpus too large to hold in memory directly.

Read, search, send, and manage messages across Gmail, Outlook, Telegram, and other platforms

Send notifications through the unified notification router

Read and write Notion pages and databases using the Notion API

Manage Outlook email — drafting, sending, organizing, rules, vacation replies, and inbox analysis

View Outlook Calendar events for any day, create and manage events, and check availability

Build or update the user's personal page — a cinematic landing page about THE USER themselves (their bio, work, life areas). Use whenever the user asks for a personal page, a page about them, or to update what's on their page. NOT for general landing pages or other apps (that's app-builder). The page already exists in the workspace; this skill is how to fill it.

Make outgoing phone calls, receive incoming calls, and pull up past call transcripts

Trigger-action automation rules for handling incoming messages

Use when the user wants to build, scaffold, ship, or edit a Vellum plugin that bundles multiple surfaces (hooks, tools, skills, and more) into one installable package.

Set up and manage ngrok-based public ingress for local assistants; do not use this in managed mode when platform callback routing is available

Create and configure a Sentry internal integration so the assistant can manage issues, alerts, and releases under its own identity

Create and manage automated email drip sequences

Manage assistant voice and system settings

Create, edit, and delete custom managed skills in the user's workspace. Use whenever the user wants to author a new skill from a description, scaffold a SKILL.md, or remove a skill they no longer need.

Read, send, and manage Slack messages via the Web API

Connect a Slack app to the Vellum Assistant via Socket Mode. Use whenever the user wants to set up Slack for their assistant, connect a workspace, or get the assistant talking in Slack — the skill generates a one-click manifest URL so they only have to name, save, and copy two tokens.

An on-demand personal daily briefing — weather, headlines, the shape of your day, and one thing worth your attention — in a sharp executive-assistant voice. The general-purpose morning brief; richer work or admin digests compose it as their general layer.

Create and configure a Stripe restricted API key so the assistant can manage payments, subscriptions, and customers under its own scoped identity

Use the Stripe Link CLI as an agent wallet to create spend requests, generate one-time-use payment credentials, and complete 402 / Machine Payment Protocol (MPP) payment flows on the user''s behalf. 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.

Spawn and manage autonomous background agents for parallel work

Handle disk pressure, critically low storage, safe storage limits, and storage cleanup mode by inspecting disk usage and proposing safe cleanup steps.

Two-layer task system with reusable templates and a prioritized work queue

Connect a Telegram bot to the Vellum Assistant gateway with automated webhook registration and credential storage
