Show Notes

Source: CHANGELOG.md — v2.1.142.

claude agents inherits session flags. claude agents now accepts --add-dir, --settings, --mcp-config, --plugin-dir, --permission-mode, --model, --effort, and --dangerously-skip-permissions. Before, dispatched background sessions just inherited daemon defaults. Now each session is per-call scoped.

Fast mode defaults to Opus 4.7. speed: "fast" and /fast now route through Opus 4.7 instead of Opus 4.6. The Opus 4.7 launch was April 16 on the platform; fast mode was still on 4.6 until this release. Pin the old behavior with CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE=1.

Root-level SKILL.md plugins. A plugin with a top-level SKILL.md and no skills/ subdirectory is now surfaced as a single skill named after the plugin. Removes the scaffolding for one-skill plugins where the skill and plugin are basically the same thing.

LSP servers in plugin details. The /plugin details pane and claude plugin details <name> now list LSP servers a plugin contributes from .lsp.json, alongside its skills, agents, hooks, and MCP servers. Surface-area transparency before install.

/web-setup safety prompt. /web-setup now confirms before replacing an existing GitHub App connection on the same org. Previously the connection was silently overwritten, breaking other users' web sessions in the same workspace.

MCP_TOOL_TIMEOUT fix for remote servers. Behavioral trap: MCP_TOOL_TIMEOUT was being ignored for remote HTTP and SSE MCP servers — calls capped at 60s regardless of the configured value. Now it actually raises the per-request fetch timeout for remote servers too, not just stdio. If you've been seeing weird one-minute aborts on mcp-remote-style servers, this is the fix.

Not in this episode: 18 bug fixes including daemon sleep/wake reconnects, brew-upgrade crash-loop, Windows network-drive deadlocks, plugin cache cleanup, and various UX fixes.
