# Overview

> The official catalog of installable tools and skills

IronHub is the catalog of tools and skills for IronClaw, hosted at [hub.ironclaw.com](https://hub.ironclaw.com). Every entry is cryptographically signed — IronClaw verifies the signature before installation so you know exactly what you're installing and who published it.

## What's in the catalog

IronHub distributes two kinds of packages:

| Kind             | What it is                                                | What you get                                  |
| ---------------- | --------------------------------------------------------- | --------------------------------------------- |
| Extension (Tool) | WASM binary + capability manifest (TOML, `manifest.toml`) | A new tool your agent can call at runtime     |
| Skill            | SKILL.md                                                  | Prompt instructions the agent loads on demand |

## Provenance tiers

Every catalog entry carries a provenance label that tells you how it was reviewed:

| Tier         | Description                                                                                                                                   |
| ------------ | --------------------------------------------------------------------------------------------------------------------------------------------- |
| **Official** | Published and maintained by the IronClaw team.                                                                                                |
| **Trusted**  | Reviewed by the IronClaw team for safety and correctness.                                                                                     |
| **Verified** | Publisher identity is confirmed, but the package has not been audited.                                                                        |
| **New**      | Community submission with no review yet. Requires explicit operator acknowledgement to install — the agent cannot install these autonomously. |
