# SkillHub

> SkillHub is an AI Agent skill registry. It indexes skills published by
> providers, attaches risk metadata, and exposes install instructions for local
> CLI use. SkillHub itself never executes third-party skill code — the user's
> local agent installs and runs them.

## Provider model

- Providers register via the skillhub CLI or the admin console.
- Skill text is HOSTED in SkillHub's database by default; `public-github` is an
  optional secondary source for providers who already have a repo.
- Public skills can be inspected and installed anonymously; private skills need a
  CLI token. Public listing is reviewed by a platform admin.
- Skill name and description are multilingual: a manifest may give them as a
  per-locale map (zh-TW/zh-CN/en/ja) or a plain string. Agent responses include
  `name_i18n`/`description_i18n`; pass `?lang=` (or Accept-Language) to get
  `name`/`description` resolved (fallback: requested → en → zh-TW → any).

## Getting the CLI

- Install with one command (no signup, no repo): `curl -fsSL https://api-skillhub.zeabur.app/install.sh | sh`
- The CLI defaults to this API; override with SKILLHUB_API_URL or `skillhub login --api-url`.

## Principles

- SkillHub indexes; the user's local agent runtime executes.
- Every install verifies sha256 against the manifest snapshot before files are written.
- Risk levels bind to declared permissions, not to repo reputation.

## Risk model

- low: install directly
- medium: summarize permissions to the user before install
- high: enumerate permissions and require user confirmation
- critical: mandatory interactive [y/N] in a TTY (cannot be bypassed by --yes)

## Versioning

- HTTP API path prefix: /api/v1 (semver; breaking changes bump to v2)
- Skill manifest schema: skillhub.yaml carries a schema_version per skill
