SkillHub marketplace

What SkillHub is

SkillHub is combo agent’s skills marketplace. It handles three jobs:

1. Discover — browse official / community / internal tenant skills
2. Subscribe — one-click install to your workspace or tenant
3. Publish — contribute custom skills for team or wider reuse

Visibility tiers

Pick visibility at publish time. You can downgrade later (Public → Tenant / Private) but cannot promote without re-publishing.

Install / update / uninstall

In-session commands:

/skill-install <skill-name>
/skill-install <skill-name>@<version>    # pinned version
/skill-list
/skill-update <skill-name>
/skill-remove <skill-name>

CLI:

combo-cli skill install <skill-name>
combo-cli skill list --installed
combo-cli skill update <skill-name>

Admin UI: Skills → Marketplace, use Install / Update / Remove.

Publishing custom skills

/skill-publish ./my-skill --visibility tenant

Or CLI:

combo-cli skill publish ./my-skill \
  --visibility tenant \
  --changelog "v1.2: bulk PDF export"

Pre-publish automation:

• Metadata validation — SKILL.md / skill.manifest.json correctness
• Contract tests — runs tests/ when present
• Security scan — Semgrep / secret scanning
• Lint — prompt length, tool signature sanity

Any failure blocks publish.

Versioning

Skills follow SemVer (Major.Minor.Patch):

Tenants may configure upgrade policy:

• auto — always latest
• minor-only — Minor/Patch only, no Major
• manual — view-only, deliberate upgrades
