Implement the Agent Skills Discovery RFC to allow fetching skills from URLs:
- Add 'urls' field to config.skills for specifying skill registry URLs
- Create Discovery namespace in skill/discovery.ts with pull() function
- Download skills from /.well-known/skills/index.json endpoints
- Cache downloaded skills to ~/.cache/opencode/skills/
- Skip re-downloading existing files for efficiency
Users can now configure:
{
"skills": {
"urls": ["https://example.com/.well-known/skills/"]
}
}
