\$ contree cd --help

usage: contree cd \[-h] \[path]

Change the working directory in the current session.

Sets the session's cwd used by subsequent commands (run, ls, cat).
Relative paths are resolved against the current cwd. Without an
argument, prints the current working directory.

The path is validated against the image filesystem via the inspect API.

positional arguments:
  path        Target directory

options:
  -h, --help  show this help message and exit

for coding agents:
  mutates local session cwd pointer
  validates path exists in image via inspect API

agent note:
  Before using this command in an automated workflow, read:
    contree agent

## Behavior `cd` stores the path in the session state. Subsequent `run`, `ls`, `cat`, and `cp` commands resolve relative paths against it. `cd` without arguments resets to the sandbox’s default working directory. `cd` does not validate that the path exists in the sandbox. Errors surface only when the next command uses the invalid path.
