Night shift report

WHY THIS MATTERS: There's no Claude Code release tonight (still v2.1.322), but three things are worth a human look. First, a Claude Tag feature looks retired: the "Managed by" page (letting another Slack channel write a channel's instructions) now redirects to attach-to-scope, and every mention of managed instructions and managing channels has been removed from the Claude Tag docs. Second, the MCP Apps developer docs grew from a quickstart into a real guide, with six new pages. Third, the Python and TypeScript SDKs shipped new Claude Tag API surface. Admins who set up managing channels will want to know where that went.

HIGHLIGHTS:

• New tombstone: claude-tag/admins/managed-by → attach-to-scope. The redirect points to scopes, but the content wasn't merged there. The "Managed by" setting, managed instructions, and "correct Claude privately from a managing channel" are gone from customize.md, restrict-access.md, good-habits.md and the Configure-page tables. This reads as a feature removal, not a move. (The local managed-by.md is still on disk; the reaper doesn't delete redirects.)
• MCP Apps: six new building guides in content/claude/connectors/building/mcp-apps/: app tools (Claude changes what's on screen), display modes (side panel and full screen), app.downloadFile, embedded sites (frameDomains and frame-ancestors), global entry points (open an app from the Artifacts page without asking Claude), and app.sendMessage. getting-started and design-guidelines were reworked to match.
• API/SDK: Python 2.8.0 / TypeScript 1.8.0 add Claude Tag metrics to analytics summaries and user reports, plus a reply_mode on Claude Tag Slack channel settings (always_awake / automatic / mention_only / thread). Bedrock and Vertex now validate and encode model IDs: they refuse empty IDs and handle ; in model IDs. The docs version bumps follow (Go 2.9.0, Java 3.8.0, and the rest).
• Claude Code artifacts: new CLAUDE_CODE_ARTIFACT_PUBLISH_EDITS=0 turns off "one-step" artifact updates. A new error, Refusing to apply edits ... a hook is configured for file edits, explains why a one-step update is blocked when a PreToolUse hook or mod on Edit/Write is active. Publicly shared artifacts now also ask before each reply to a comment.
• Plugin hardening: plugin MCP/LSP server file paths that are absolute or contain .. are now refused (path not read). Share files between plugins with symlinks instead. plugins/loading.md also gains a section on why enabledPlugins in an --add-dir directory may not load, depending on --setting-sources.
• Agent SDK structured outputs: a success subtype no longer means you have an answer. All examples now also check !is_error, because an API error or refusal on the final request can still report success. Anyone copying the old sample code should update it. The TS SDK also gains overageEnabled on usage-limit warnings and a "mcp_task" task type for backgrounded MCP calls.
• Claude Code projects UI changes: the Overview "tabs" are replaced by Threads and Library buttons and a ⋯ menu (Settings, Scheduled tasks), and the upload limit rises to 1,000 files and 2 GB per batch.
• Ops docs: corporate-proxy installs now need both CURL_CA_BUNDLE and NODE_EXTRA_CA_CERTS. The OTel metrics endpoint example now includes /v1/metrics. Hooks docs explain how to start a long-running dev server from a hook without a 10-second hang.
• Claude Science: new Git/GitHub troubleshooting. SSH is off in the sandbox, so pushes go over HTTPS with a saved GitHub token. It also covers the limits for non-github.com hosts and Git LFS.
• Support (new): Fable 5.2 launch offers (Fable resets by plan), why conversations on Fable models switch models when a request is blocked, sharing voice recordings with Anthropic (opt-in, iOS/Android only), and a Mac mini + Team plan offer through CDW.
