# Licensing & provenance

> How Solid State labels skills: kind, provenance, and SPDX licenses. The honest-directory schema explained.

Every listing on solidstate.cc carries three labels. None of them are decorative.

## Kind

| Value      | Meaning                                                                   |
| ---------- | ------------------------------------------------------------------------- |
| `original` | Authored by Solid State. We wrote it, we maintain it, we answer for it.   |
| `listing`  | Indexed from upstream. The author is the author. We link, we don't claim. |

## Provenance

Where the skill actually comes from. `first-party` means us. Everything else names the upstream source — ClawHub, skills.sh, Hermes, a GitHub repo.

There is no "verified" badge. A boolean that says "trust me" is a facade. Provenance is a pointer you can follow.

## License

Stated as an SPDX identifier. The accepted set:

`MIT` · `MIT-0` · `Apache-2.0` · `BSD-3-Clause` · `BSD-2-Clause` · `ISC` · `GPL-3.0` · `AGPL-3.0` · `MPL-2.0` · `Unlicense` · `CC0-1.0` · `source-available` · `proprietary`

Two special cases:

* **`undeclared`** — the upstream repo states no license. The listing shows it plainly. Use at your own judgment; legally, no license means all rights reserved.
* **`unknown`** — we refuse to render it. If we can't determine the license, the skill doesn't get listed.

## Why this schema exists

Marketplaces inflate. Install counts get invented, "verified" badges get sold, authorship gets blurred.

The rules here are baked into the data model:

* No install count we haven't measured.
* No authorship we don't hold.
* No repo link that 404s.
* No license field that hides what it doesn't know.

A directory is only useful if you can trust its labels. That's the whole product.
