Check Vellum Assistant architecture and package boundaries. Use when editing imports, moving code, adding endpoints, touching assistant/gateway/client/skill boundaries, or reviewing architecture-sensitive changes.

Review Vellum Assistant code changes for correctness, repo-specific quality rules, security risks, and missing validation. Use when reviewing diffs, preparing a PR, finishing implementation work, or when the user asks for a code review, quality pass, or pre-merge check in this repository.

Guide Vellum Assistant feature flag changes and rollout hygiene. Use when adding, editing, reviewing, or documenting assistant feature flags, rollout-gated behavior, or platform flag follow-up work.

Validate Vellum Assistant database and workspace migrations. Use when adding, editing, reviewing, or testing migrations, release-note migrations, persisted schemas, workspace file formats, or data backfills.

Prepare Vellum Assistant branches for review by checking git hygiene, PR scope, tests, docs, migrations, Linear linking, and companion repo needs. Use before creating a pull request, splitting work into PRs, or asking whether a branch is ready.

Author and review first-party Vellum skills in the repository. Use when editing files under skills/, assistant bundled skills, skill manifests, tool definitions, SKILL.md files, or first-party skill portability and isolation behavior.

Select focused verification commands for Vellum Assistant changes. Use when deciding what tests, typechecks, lints, or smoke checks to run after editing this repository, especially before commits and pull requests.

Review Vellum Assistant user-facing copy, examples, docs, CLI output, UI strings, and assistant-facing release notes. Use when editing text users may read, including README files, SKILL.md files, CLI messages, route errors, update bulletins, and client UI labels.

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

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).

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

Control the macOS desktop

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

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.

Track sent messages awaiting responses across communication channels

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.

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

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

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

Trigger-action automation rules for handling incoming messages

Recurring and one-shot scheduling - cron, RRULE, or single fire-at time

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.

Spawn and manage autonomous background agents for parallel work

Transcribe audio and video files using the configured speech-to-text provider

Shop on Amazon and Amazon Fresh through your browser

Record and analyze API surfaces of web services

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.

Import conversation history from ChatGPT into Vellum

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

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.

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

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

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.

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

View, create, and manage Google Calendar events and check availability

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

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

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

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.

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

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.
