TL;DR

• Fast mode silently switched to Opus 4.7. If your fast-mode workflows depend on Opus 4.6 behavior, set CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE=1 to pin to the old model.

• MCP_TOOL_TIMEOUT was not actually raising the fetch timeout for remote HTTP/SSE servers. Tool calls were capped at 60 seconds regardless of the configured value; if you set a higher timeout and still hit 60s walls, this is your fix (more below).

• claude agents can now configure sessions at dispatch time. New flags --add-dir, --settings, --mcp-config, --plugin-dir, --permission-mode, --model, --effort, and --dangerously-skip-permissions let you customize background agents without separate configuration.

• Background agents no longer disappear after macOS sleep or binary upgrades. The daemon now detects clock jumps and exits cleanly when the binary path changes, fixing two classes of crash-loops (more below).

New in 2.1.142

2.1.142 (May 15, 2026)

• Added new claude agents flags: --add-dir, --settings, --mcp-config, --plugin-dir, --permission-mode, --model, --effort, and --dangerously-skip-permissions to configure dispatched background sessions
• Fast mode now uses Opus 4.7 by default (previously Opus 4.6). Set CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE=1 to pin fast mode to Opus 4.6
• Plugins with a root-level SKILL.md and no skills/ subdirectory are now surfaced as a skill
• The /plugin details pane and claude plugin details now show LSP servers a plugin provides
• /web-setup warns before replacing an existing GitHub App connection
• Fixed MCP_TOOL_TIMEOUT not raising the per-request fetch timeout for remote HTTP and SSE MCP servers, which capped tool calls at 60 seconds regardless of the configured value
• Fixed background sessions not recognizing pre-existing git worktrees, blocking Edit while EnterWorktree refused to create a duplicate
• Fixed background sessions disappearing and daemon reconnect failing after macOS sleep/wake; the daemon now detects clock jumps instead of treating them as elapsed idle time
• Fixed daemon not exiting cleanly after the binary is upgraded (e.g. brew upgrade), causing dispatched agents to crash-loop on the deleted path
• Fixed background agents crash-looping when the Claude-in-Chrome extension is connected without a shared tab
• Fixed clicking links in an attached claude agents session; the background worker's headless browser shim no longer applies while attached
• Fixed claude agents "v to open in editor" using the daemon's default editor instead of your shell's $EDITOR/$VISUAL
• Fixed claude agents deadlocking on Windows with network-drive working directories; Ctrl+C now works during startup
• Fixed background-color bleed when attaching to a claude agents session from Apple Terminal or other 256-color-only terminals
• Fixed claude --bg --dangerously-skip-permissions not persisting across retire/wake
• Fixed session titles being derived from the URL when the first message is a link
• Fixed redundant set_model requests from remote clients injecting duplicate /model breadcrumbs into the transcript
• Fixed plugins using skills: ["./"] showing a false "path escapes plugin directory" error
• Fixed plugin cache cleanup deleting the active plugin version directory when no installation metadata is present
• Fixed /plugin browse pane showing "0 installs" for newly published plugins
• Fixed plugin advisories not naming every plugin.json key that shadows a default folder
• Improved reactive compaction: the first summarize attempt now seeds from the original request's overflow size, avoiding a wasted near-full-context retry
• Improved hook configuration error: configuring a prompt- or agent-type hook for SessionStart/Setup/SubagentStart now shows a clear "use a command-type hook instead" error
• Removed stale /model claude-sonnet-4-20250514 suggestion from Usage Policy refusal messages
