• NEW: Data: Tool result display metadata field — Documents wrapper-level SDK metadata for non-execution reasons, remedies, permission decisions, and human denial feedback; never replayed to the model.
• NEW: System Prompt: Finish the request instead of stopping early — Adds feature-gated Haiku 5.5 completion guidance: finish large and unblocked requests without unnecessary check-ins, while retaining approval for consequential actions.
• NEW: System Reminder: Background command quiet check-in — Requires inspecting silent background commands for progress or hangs, stopping stuck work, and ending the turn for healthy long-running commands.
• Tool Description: Artifact design fallback requirements, Artifact page implementation requirements (app wording) and Artifact publishing and update guidance — Require library URLs to pin exact versions at least two weeks old, rejecting bare names, ranges, and tags.
• Data: Message Batches API reference — Python — The classification example now sets max_tokens=1024 with low effort, noting Haiku's default thinking counts toward max_tokens.
• Data: SDK result safety_stops field — Counts content-filter stops only when they end the call; retried stops remain uncounted, so zero does not rule them out.
• Data: syncClaudeAiSkills setting — Skills re-sync about every 10 minutes while a session is in use, and a quarter as often otherwise.
• Data: Background tasks changed event schema — Removes the claim that the payload carries only IDs while retaining the warning not to correlate level changes with edge events.
• Tool Description: claude.ai Project — Adds a main-conversation upload mode for unchanged files read or written in full this session, using absolute paths without repeating their contents.
• Tool Description: Agent (usage notes) and System Reminder: Async agent launched metadata — Condition continuation instructions on availability, explaining that unsupported sessions start fresh agents and omitting unusable SendMessage hints.
• System Reminder: Remote Chrome browser extension not connected — For multi-organization users, requires matching the extension's organization; reserves logout for failed checks, with advance warning about erased shortcuts and scheduled tasks.
• Agent Prompt: Claude Test explorer — Rewords the file-access restrictions to require compliance in every Read, Grep, and Glob instead of emphasizing the agent's sole responsibility.
