What it does
Attio Hello World is an agent skill from jeremylongshore/tons-of-skills-marketplace. Prove the smallest safe Attio REST connection by listing objects and validating the response envelope without changing CRM data. Use when checking a new token, workspace, or integration path. Trigger with "Attio hello world", "first Attio request", or "test Attio connection".
Its SKILL.md is about 880 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 Sales & Support. 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
- Checking a new token
- Integration path
- With Attio hello world
- First Attio request
Example prompts
- “Attio hello world”
- “first Attio request”
- “test Attio connection”
- “/attio-hello-world”
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.
- Confirm the repository, runtime, workspace alias, secret source, and granted scope.
- Add or inspect a tiny request wrapper with explicit base URL and Bearer header injection.
- Request /objects with a bounded timeout and capture status plus content type.
- On success, parse data and record only object slugs or counts that are safe to expose.
- Assert that at least one expected object is visible to the workspace.
- Add a fixture test for success plus 401, 403, and non-JSON failure handling.
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:
ReadGlobGrepWebFetchWriteEdit
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
Hosts in commands or code, which the agent is likely to contact:
api.attio.com
Also links to:
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 Hello World loads about 881 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 340 words of instructions outside code blocks.
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 Verified First Read
Overview
This skill proves authentication, workspace reachability, JSON parsing, and object discovery with one read-only request. It does not create a demonstration contact in a real CRM.
Prerequisites
- A named repository and non-production or approved workspace
- A single-workspace access token or OAuth access token
- The
object_configuration:readscope required by the object-list endpoint - A runtime with HTTPS and JSON support
Tool Discipline
Use Read, Glob, and Grep to inspect the local client, environment-variable names, and tests. Use WebFetch only for current official Attio documentation. Use Write or Edit after confirming the repository and intended implementation file.
Current Contract
- Base URL:
https://api.attio.com/v2. - Send
Authorization: Bearer <access_token>; Bearer authentication is the recommended form. - Start with
GET /v2/objectsand validate a{ data: [...] }response. - Keep the credential out of source, output, exceptions, and request logging.
Authentication
Use a workspace API key for a single workspace or OAuth for an app serving multiple workspaces. Do not request write scopes for this proof.
Instructions
- Confirm the repository, runtime, workspace alias, secret source, and granted scope.
- Add or inspect a tiny request wrapper with explicit base URL and Bearer header injection.
- Request
/objectswith a bounded timeout and capture status plus content type. - On success, parse
dataand record only object slugs or counts that are safe to expose. - Assert that at least one expected object is visible to the workspace.
- Add a fixture test for success plus 401, 403, and non-JSON failure handling.
Approval Boundaries
Do not add create, update, assert, or delete calls to the first-read proof. Never print the access token or persist a raw workspace response.
Output
Return the redacted configuration, status, response-envelope assertion, safe object summary, fixture-test result, and next integration boundary.
Error Handling
| Condition | Response |
|---|---|
| 401 | Verify credential injection and replace an invalid token. |
| 403 | Confirm object_configuration:read without broadening other scopes. |
| Non-JSON response | Preserve status/content type and stop parsing. |
| Unexpected workspace data | Stop and verify workspace identity. |
Examples
Input:
workspace=development; request=GET /v2/objects; writes=forbiddenExpected handoff:
