docs: Batch API supports Threads + cache hints; Claude Science org skills; enterprise surveys launched

[claude-yolo]

Night shift report

WHY THIS MATTERS: The batch API just got meaningfully more capable — three previously-blocked parameter families (Threads/store, cache routing hints, and research preview mode) have been removed from the "not supported" table, meaning developers can now run stateful thread-based requests, apply cache hints, and use research preview through the async batch path. That's a non-trivial surface expansion for anyone doing high-volume async processing. Separately, two new product features landed with fresh support articles: a revamped Cowork artifacts system (GA since August 19) and an enterprise-only in-product survey tool for admins. Claude for Science also gets org-level skill push — admins can now distribute skills to every user in the org rather than relying on individuals to import them.

HIGHLIGHTS:

• Batch API expansion (content/en/build-with-claude/batch-processing.md): store/previous_thread_event_id (Threads), cache_hint/context_hint, and research_preview_2026_02 all removed from the unsupported parameters table — these are now valid in batch requests. The FAQ answer updated accordingly.
• New: Enterprise surveys (content/support/16764057-create-surveys-for-your-organization.md): New Enterprise-beta feature; admins can schedule in-product surveys (Cowork or chat) with default questions around Claude value, aggregate answers in Analytics console. CMEK orgs excluded for now.
• New: Cowork artifacts system (content/support/14729249-use-artifacts-in-claude-cowork.md): Updated artifacts are shareable, web-accessible, versioned, and connectable. Live artifacts created before August 19 are read-only going forward. CMEK/ZDR/HIPAA orgs stay on old live artifacts.
• Claude Science org skills (content/claude/claude-science/admin-controls.md): New "Organization skills" section — admins can push skill .zip files to all org members via claude.ai, or point members to a GitHub repo for self-managed skill imports with per-commit tracking.
• "Skill and plugin security scanning" went GA (content/support/13930452-manage-custom-roles-on-enterprise-plans.md): "(beta)" label dropped from the custom roles capability table.
• Government analytics clarification (content/claude/government/org-admin/analytics.md): "By product" and "Top users" table descriptions clarified — Chat+Cowork in Desktop counted together; Claude Code in Desktop counted in the Claude Code row; Top users figures combine across all products.
• Agent SDK minor wording (content/en/docs/claude-code/agent-sdk/typescript.md): "slash commands" renamed to "commands" in supportedCommands() and the SlashCommand type description.
• Claude Desktop config changelog (content/claude/third-party/claude-desktop/configuration-changelog.md): Release date corrections for v1.10628.0 through v1.6259.0 (1–4 day shifts; editorial cleanup).
