Overview - Joy

IronHub is the catalog of tools and skills for Joy, hosted at hub.joy.com. Every entry is cryptographically signed — Joy 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 Joy team.
Trusted	Reviewed by the Joy team for safety and correctness.
Verified	Publisher identity is confirmed, but the package has not been audited.
Private	Scoped to a specific organization or team — not publicly listed.
New	Community submission with no review yet. Requires explicit operator acknowledgement to install — the agent cannot install these autonomously.
