Skill Hub Installer

When you detect the user wants to install a remote skill or mentioning SkillHub:

Recognition Patterns

• Direct SKILL.md URL: "安装这个 https://skillhub.cn/raw/my-skill.md"
• Catalog link: "从 skillhub 装个 xxx"
• Explicit request: "帮我安装一个 skill，URL 是..."

Installation Steps

1. Validate URL

   • Must be https:// protocol
   • Common formats: GitHub raw, SkillHub endpoints, personal git servers

2. Parse & Import

   skill_manage(
      action='import_from_url',
      source_url='https://skillhub.cn/install/skillhub.md',
      skill_name='auto'  # or explicit name
   )
   

   System will:

   • Fetch the SKILL.md content
   • Extract name: field from YAML frontmatter
   • Create skill directory under workspace/skills/
   • Make it available on next turn

3. Verify Success Check response:

   • ✅ ok=True → skill installed and ready
   • ❌ ok=False → network error, invalid format, name conflict

Example Workflows

User says: "给我装个 skill，地址是 https://skillhub.cn/install/arxiv-daily.md"

You call:

skill_manage(
  action='import_from_url',
  source_url='https://skillhub.cn/install/arxiv-daily.md'
)

User says: "我想用这个 skill hub: https://github.com/org/skill-registry/blob/main/skills/SKILL.md"

You call:

skill_manage(
  action='import_from_url',
  source_url='https://raw.githubusercontent.com/org/skill-registry/main/skills/SKILL.md'
)

Common URL Conversions

Format	Raw URL
GitHub blob	https://github.com/.../blob/main/SKILL.md
SkillHub	https://skillhub.cn/view/skill-id
GitLab	https://gitlab.com/.../blob/main/SKILL.md

Restrictions

• Only https:// URLs (no http:// for security)
• Max 256 KiB per SKILL.md
• Name must match pattern: [a-z0-9][a-z0-9._-]{0,63}
• Cannot overwrite existing skills (user must archive or delete first)

Error Handling

• HTTP errors (404, 500): Report the status code, suggest checking URL
• Name conflict: Suggest skill_manage action='archive' skill_name='...' then retry
• Invalid format: The YAML frontmatter is malformed; ask user to verify source
• Size limit: SKILL.md exceeds 256 KiB; ask for a compressed version
