What it does

Vellum OAuth Integrations is an agent skill from vellum-ai/vellum-assistant. Act on behalf of your user in any third-party software that supports OAuth 2.0

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 37 other files, including reference files (for example `references/CONFIGURING_APPLICATIONS.md`, `references/CONNECTING_ACCOUNTS.md` and `references/MAKING_REQUESTS.md`). Compatibility notes: Designed for Vellum personal assistants

It sits in Backend & APIs, covering OAuth and OpenID Connect. The repository describes itself as: An AI Assistant that’s easy to setup, does your work 24/7, knows your preferences and gets better over time. The licence is MIT.

When your agent uses it

  • Tasks that involve OAuth and OpenID Connect

Example prompts

  • “/vellum-oauth-integrations”

Requirements

  • Compatibility (from SKILL.md): Designed for Vellum personal assistants

What it can do on your machine

Read from SKILL.md and the folder at commit 33cc983. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • jq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Vellum personal assistants

    From compatibility in the SKILL.md frontmatter.

Context cost

Vellum OAuth Integrations loads about 1.5k tokens when it runs, and up to ~39k if it reads all its reference files. Until then it costs about 26 tokens; SKILL.md has 729 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~39k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Using OAuth Integrations

Integrating with a third-party software via OAuth is typically used to perform actions on behalf of the user. It involves having the user log in using their own credentials, specifying the scopes that they want to provide, and then afterwards, API requests can be made on their behalf.

Important: Avoid reaching for an OAuth integration if your intent is to act as yourself rather than as your user.

The Assistant OAuth CLI

You are provided with the assistant oauth CLI for performing all necessary oauth-related actions.

Important: When in doubt how a command works or how to do something, read the references at the bottom. Never guess at how the CLI works. Read references and use the --help flag for any command you're about to run.

Viewing Available OAuth Providers

Vellum assistants can natively integrate with any application that supports OAuth 2.0. Many OAuth providers come pre-configured and ready to use. You can view them by running:

bash
assistant oauth providers list

You can also search for specific providers. Here's an example that searches for the "google" provider:

bash
assistant oauth providers list --provider-key google

Managed vs Your-Own Mode

All providers support "your-own" mode and some support "managed" mode.

Default: Managed Mode

"managed" mode relies on a first-class integration with the Vellum Platform. Managed mode is typically easier to set up and get going, often only requiring the user to log in with no additional configuration needed before they can begin using the integration. Managed mode is the recommended method for most users, especially those that are less technical or newer to their Vellum assistant.

When a task needs a managed OAuth connection, present it in chat with ui_show using surface_type: "oauth_connect" instead of sending the user to Settings or trying to open the OAuth flow from shell. See Connecting Accounts for the exact surface shape.

Note that using managed mode:

  • Requires an account with the Vellum Platform
  • May result in billable usage
  • Requires that requests to the third party are sent through Vellum's servers
Your-Own Mode

"your-own" mode requires that the user creates their own OAuth application directly with the third-party and then enter the application's Client ID and Client Secret into Vellum.

Your-own mode is typically best if:

  • Vellum does not have a first-party integration with the provider and managed mode is not supported
  • The user is more tech-savvy and comfortable setting up OAuth apps
  • The user does not want to create an account with the Vellum Platform
  • The user is more sensitive to potential billing implications
  • The user is sensitive to their data going to the Vellum Platform

How to Choose

Default to managed mode whenever the provider supports it. Check support with:

bash
assistant oauth providers get <provider-key> --json | jq -r '.managedServiceConfigKey'

If this returns a non-null value, managed mode is supported and should be your starting recommendation. Only fall back to your-own mode if:

  • The provider does not support managed mode (managedServiceConfigKey is null), OR
  • The user explicitly wants their own OAuth app (e.g. they're running self-hosted, they're privacy-sensitive, they're configuring a per-assistant Slack app), OR
  • The user already has a working your-own connection — don't re-recommend managed mid-flow for already-connected providers.

Do not present managed and your-own as equivalent choices to a fresh user. Lead with managed, then offer your-own as an alternative if they push back.

Differentiating & Setting a Provider's Mode

You can determine whether a given provider supports managed mode based on the details returned by:

bash
# Find the provider of interest in the list response
assistant oauth providers list

# Or, return just the provider of interest with their details
assistant oauth providers get <provider-key>

You can determine what mode the provider is currently set to use with:

bash
assistant oauth mode <provider-key>

You can update which mode a given provider should use with:

bash
assistant oauth mode <provider-key> --set "managed"|"your-own"

Troubleshooting

Permission / Insufficient Scope Errors

If an API request returns a 403 Forbidden, 401 Unauthorized, or a message about missing scopes, the connection likely doesn't have the scopes needed for that action. See Updating Scopes for how to disconnect and reconnect with the required scopes.
