Output contract

• Human output is concise and intended for a terminal.
• --json output is stable machine data where a command supports it.
• Diagnostics and usage errors use standard error.
• MCP standard output contains protocol frames only.

Current capability

The private-beta CLI creates and inspects local macOS device keys, validates the public synthetic approval fixture, and exposes read-only MCP discovery and protocol tools. It does not currently expose a supported secret-reveal, approval, grant, or action-execution command.

Run c6s help from the installed version as the authoritative command list.
