What it does

Attio Install Auth is an agent skill from jeremylongshore/tons-of-skills-marketplace. Choose and configure Attio REST authentication for a single workspace or multi-workspace OAuth app, including least-privilege scopes and a read-only verification. Use when connecting a service to Attio. Trigger with "Attio auth", "Attio API key", or "Attio OAuth setup".

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering OAuth and OpenID Connect and Authentication. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Connecting a service to Attio
  • With Attio auth
  • Attio OAuth setup

Example prompts

  • “Attio auth”
  • “Attio API key”
  • “Attio OAuth setup”
  • “/attio-install-auth”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Classify the integration as single-workspace or multi-workspace.
  2. Inventory methods and endpoints, then derive scopes from their current reference pages.
  3. Define secret storage, tenant-to-token mapping, rotation, revocation, and audit ownership.
  4. Implement server-side credential injection without token logging.
  5. For OAuth, bind and verify state; never expose the client secret to browser code.
  6. Verify with one read-only endpoint and record only status, workspace alias, and granted scope names.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • WebFetch
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.attio.com

    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 Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Attio Install Auth loads about 960 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 384 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~960
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

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.

Attio Authentication Setup

Overview

This skill selects the correct Attio access-token path, maps endpoint scopes, and proves the credential with a non-mutating request.

Prerequisites

  • The integration's workspace and tenancy model
  • Exact endpoints and operations the application will use
  • An approved secret store and rotation owner
  • Registered redirect URIs when OAuth is required

Tool Discipline

Use Read, Glob, and Grep to inspect the local auth wrapper, secret names, redirect configuration, and endpoint use. Use WebFetch only for current official Attio documentation. Use Write or Edit after the auth model and target files are confirmed.

Current Contract

  • Prefer OAuth 2.0 for an app that serves multiple Attio workspaces.
  • Use a manually generated workspace API key for one controlled workspace.
  • Both credential types can be sent as Authorization: Bearer <access_token>.
  • Required scopes are documented per endpoint and should be granted operation by operation.
  • Attio also supports Basic authentication with the token as username and an empty password, but Bearer is recommended.

Authentication

For OAuth, validate state, use the registered redirect URI exactly, exchange the code server-side, and encrypt the resulting token at rest. For a workspace key, create it in developer settings with the minimum scopes and store it only in the approved secret manager.

Instructions

  1. Classify the integration as single-workspace or multi-workspace.
  2. Inventory methods and endpoints, then derive scopes from their current reference pages.
  3. Define secret storage, tenant-to-token mapping, rotation, revocation, and audit ownership.
  4. Implement server-side credential injection without token logging.
  5. For OAuth, bind and verify state; never expose the client secret to browser code.
  6. Verify with one read-only endpoint and record only status, workspace alias, and granted scope names.

Approval Boundaries

Do not generate or broaden production credentials, modify redirect URIs, or migrate tenant tokens without the owning administrator's approval and a rollback plan.

Output

Return the chosen auth model, endpoint-to-scope map, secret reference, OAuth control evidence if applicable, read-only verification, and rotation owner.

Error Handling

ConditionResponse
Tenancy model is unclearStop before choosing a credential type.
OAuth state mismatchReject the callback and start a fresh authorization flow.
403 after verificationCompare the exact endpoint scopes; do not grant all scopes.
Token appears in logsRevoke or rotate it and scrub retained output.

Examples

Input:

text
tenancy=multiple-workspaces; endpoint=GET /v2/tasks; storage=encrypted-server-side

Expected handoff:

text
auth=oauth; state=verified; scopes=endpoint-derived; read-test=pass
