Agent Metadata
Known Gotchas
- ⚠ Project slug format: github/org/repo — agents must construct correctly
- ⚠ Pipeline IDs and workflow IDs are UUIDs — query to discover
- ⚠ Personal tokens have no scope granularity — full account access
- ⚠ Build artifacts expire — agents must retrieve within retention period
- ⚠ Contexts are org-level — project-level context access requires org membership
- ⚠ API v2 is current but some features only in v1 — check endpoint documentation
