A field-by-field summary of what the reviewed first-party references actually support. Publisher update dates and BYO-UI review dates are shown separately below.
02 · Data you can retrieve
Writer knowledge, applications, and supported platform context.
03 · Actions and write paths
Writer generation and supported API actions; exact tools depend on the selected server/gateway.
04 · Authentication and permissions
Writer API or enterprise authentication Workspace, application, and connected-server permissions apply.
05 · Monitoring, approval, and recovery
Consequential writes should require explicit review; use vendor confirmation controls where available. Separate provider, gateway, and custom connector roles must not be collapsed into one capability claim.
06 · Gaps and implementation limits
Separate provider, gateway, and custom connector roles must not be collapsed into one capability claim.

Single-platform patterns
- Governed brand-content and knowledge workflow
- Campaign asset assembly room
- Brief-to-experience studio
- Content approval queue
Multi-platform compositions
- Writer + CRM or campaign platform: campaign asset assembly room
- Writer + work-management system + analytics or distribution platform: cross-system decision workspace
Evidence and dates
First-party references, with publisher and review dates separated
“Publisher updated” is shown only when the page exposes an update date. “BYO-UI reviewed” records when this research checked the reference. A missing publisher date is reported as missing—not replaced with the review date.
