Runtime description

The following is the tool's own agent-facing description, reproduced from the reviewed registry. It can contain implementation terminology; it does not expand the public stability commitment.

Read the agent-facing description

Shell command with auto-compression (~95 patterns). Alias for ctx_shell.
Output is compressed for token savings. For verbatim output pass raw=true.
Use when your MCP client prefers shell/bash over ctx_shell — transparently
delegates to ctx_shell internals.
