12Move a session with /cd
13v2.1.169
14
15The new `/cd` command moves the current session to a different working directory without rebuilding the prompt cache: the new directory's `CLAUDE.md` is appended as a message instead of replacing the system prompt. The session relocates to the new directory's project storage, so `--resume` and `--continue` find it there. Claude prompts you to trust the directory if you haven't worked in it before.
16
17Move the session into another project without restarting:
18
19```text Claude Code theme={null}
20> /cd ../other-project
21```

25Subagents can spawn subagents
26v2.1.172
27
28Subagents can now spawn their own subagents. The subagent panel below the prompt shows the full tree: each row carries a count of its descendants and a path back to `main`. Subagent chains are capped at five levels deep to prevent runaway concurrent trees.
29
30Open the agents view to watch the nested tree as work fans out:
31
32```text Claude Code theme={null}
33> /agents
34```

38Troubleshoot with safe mode
39v2.1.169
40
41Start Claude Code with `--safe-mode`, or set `CLAUDE_CODE_SAFE_MODE`, to launch with all customizations disabled: `CLAUDE.md`, skills, plugins, hooks, MCP servers, and custom commands and agents do not load. Authentication, model selection, built-in tools, and permissions still work. If a problem disappears in safe mode, one of those surfaces is the cause.
42
43Launch a clean session to isolate a broken configuration:
44
45```bash terminal theme={null}
46claude --safe-mode
47```
