Night shift report

WHY THIS MATTERS: Mods gain their most powerful hook yet: a new settings.read event lets a mod see, rewrite, or refuse any setting Claude Code reads. That puts configuration itself inside what plugins can control, so people who build mods and admins who audit them both need to know. The TypeScript Agent SDK also gets three new control methods. One of them lets embedders keep a single MCP server under stricter permissions while the rest of the session runs in bypassPermissions or auto. That closes a real gap for unattended agents. Desktop SSH on Windows can now use the real OpenSSH client and ~/.ssh/config (including ProxyJump and CertificateFile). Windows tasks also survive a Desktop restart starting in v3.1623.0. No deletions, tombstone changes, or discovery changes.

HIGHLIGHTS:

• Mods: settings.read hook (plugins/mods/events.md, reference.md, api.md, troubleshoot.md). It can change one setting, refuse a read, and tell Claude Code's own reads from a mod's reads (e.layers / e.source). api.md adds a way to read all settings, one source, or one key. New troubleshooting entries cover calls refused in claude -p and Agent SDK sessions, and a claude -p run that never exits because of a mod. Hook docs now say a hook that throws or times out is skipped, so a held command still runs unless you chain a .catch handler that denies it. That matters for any mod used as a security gate. Interface docs add rules for which controls need a key.
• Agent SDK (TypeScript), new Query methods:
  • setMcpPermissionModeOverride(serverName, 'default' | 'auto' | null) sets a stricter permission mode for one MCP server's tools. It only takes effect in bypassPermissions or auto sessions, so it can never widen what the session allows.
  • seedReadState(path, mtime) marks a file as already read, so a later Edit doesn't fail with File has not been read yet. Requires SDK v0.2.83 or later.
  • backgroundTasks(toolUseId?) does from code what Ctrl+B does in the terminal: it moves running Bash commands and subagents to the background.
  • getSessionMessages gains includeSystemMessages (for example, compact boundaries).
• Desktop SSH on Windows (desktop.md): Desktop can connect through Microsoft's OpenSSH 9.4+ (needs Desktop v2.2553.0+, not the Microsoft Store build). A new section explains what the built-in client supports when OpenSSH isn't available. MaxSessions 1 servers work from macOS/Linux on v3.1623.0+. Long tasks on Windows now come back after Desktop quits or restarts, starting in v3.1623.0.
• Sandbox failIfUnavailable behavior made clearer: if the sandbox passes the startup check but later fails to initialize, the session keeps running and refuses every sandboxed command (Sandbox is required ...). It also ignores dangerouslyDisableSandbox retries. errors.md adds two new error strings. On Linux/WSL2, leftover sandbox placeholder files can now break later settings writes.
• PreToolUse hook timeout fix (docs): when one hook times out, a deny from another hook still reaches Claude instead of being replaced by the timeout message.
• Claude projects: a local session connected through Remote Control can now hand its work into a project from the claude.ai/code sidebar.
• Self-hosted runners: new PromQL recipe that joins idle-session time to claude_code_cost_usage_total on ccr_session_id, to show what idle sessions are costing.
• Small edits: glossary (compaction), features-overview (skills preloaded into subagents), plugin docs cross-links. About 45 support articles had wording and image-token refreshes.
