What Attio Pack is
Attio Pack is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. 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.”
A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.
Installing Attio Pack adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.
How to install Attio Pack
Claude Code
- Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
- Install the plugin: claude plugin install attio-pack@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
- Restart the session if the new skills or commands don't appear straight away.
Claude Cowork
- Open Customize → Plugins and choose Add marketplace.
- Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).
- Find Attio Pack in the list, click Install, then connect any connectors it needs from its Connectors tab.
New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.
Inside the source file

> 18 Claude Code skills for building, releasing, and operating Attio CRM integrations safely.
What This Is
A production operator pack grounded in Attio's current REST, OAuth, App SDK, rate-limit, and webhook documentation. The skills cover records, lists, authentication, typed clients, testing, deployment, security, reliability, migration, cost, and performance without fabricated universal pagination, historical migration, or signature contracts.
Installation
/plugin install attio-pack@claude-code-plugins-plusSkills
Current Contract
- Attio REST uses https://api.attio.com/v2; required scopes remain endpoint-specific.
- OAuth is the default for multi-workspace applications, while a workspace API key suits one controlled workspace. Both can use Bearer authentication.
- Pagination is endpoint-specific. Record and entry queries use limit and offset, while other endpoints can expose cursor pagination.
- Attio currently documents global ceilings of 100 read requests per second and 25 write requests per second, plus score-based query limits. Reverify hosted limits before production rollout.
- Webhook signatures use SHA-256 HMAC over the exact raw request body. Delivery is at least once, so durable idempotency and reconciliation remain application responsibilities.
- Production mutations require explicit target validation, owned-field boundaries, read-after-write evidence, and rollback or cleanup receipts.
Each skill includes a dated references/official-docs.md and declares only the file and documentation tools it uses.
Quality
All 18 operator skills pass the marketplace validator at Grade A and the five-check Tier-2 production gate. Regression coverage prevents universal cursor-pagination claims, timestamp-based signature inventions, unsafe diagnostic dumping, and generic historical migration claims from returning.

Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
