Conciseness

Dense with framework-specific facts Claude cannot know (registration location rationale, requireOrgMemberForUserShares threat model, batch resourceIds semantics) with no generic-concept padding; minor tightening opportunities remain — agentRead is explained twice and the public-visibility paragraph runs long. Efficient with minor instances of over-explanation, not every token earning its place.

Actionability

Fully executable, copy-paste-ready snippets for every step (schema with ownableColumns, registerShareableResource, accessFilter query, assertAccess action, owner-setting insert with auth guard, ShareButton) plus an actions table with exact arg signatures, covering common cases including migration and debugging.

Workflow Clarity

The build flow (schema → register → filter → guard → owner → UI) is sensibly ordered, the migration pattern is an explicit 8-step checklist, and the Debugging section plus the batch action's check-first-then-apply semantics provide error recovery; but validation checkpoints live in a debugging appendix rather than inline verify steps — clear sequence with most checkpoints, minor gaps.

Progressive Disclosure

No bundle files exist and the single-file body is well-sectioned and navigable, but at ~300 lines the full 'Standard share surface' spec and actions table are long enough that they could plausibly live in one-level-deep reference files; good structure with minor organization gaps rather than a lean overview with references.

Specificity

Lists three concrete actions ('making a resource table ownable, wiring list/read/update access checks, or dropping the standard share dialog into a template') covering schema, backend, and UI, but the lead 'what' ('Framework-level sharing and privacy for user-authored resources') is moderately abstract and 'etc.' leaves coverage open — several specific actions with minor gaps, not comprehensive.

Completeness

Explicitly answers both: what ('Framework-level sharing and privacy for user-authored resources (dashboards, documents, forms, decks, etc.)') and when ('Use when making a resource table ownable, wiring list/read/update access checks, or dropping the standard share dialog into a template') with concrete trigger phrases, in third person.

Trigger Term Quality

Includes natural terms a developer would say ('share dialog', 'access checks', 'sharing', 'dashboards, documents, forms, decks'), but common synonyms like 'permissions', 'visibility', or 'ACL' are absent — good keyword coverage with a few natural terms missing.

Distinctiveness Conflict Risk

A clear niche — this framework's sharing primitive — with distinct, specific triggers ('resource table ownable', 'share dialog', 'list/read/update access checks'); a user asking for any of these would unambiguously land here, giving minimal conflict risk.
