cardano-cli-doctor

When to use

• Before generating CLI workflows to detect correct command style (era-prefixed vs legacy)
• When debugging CLI flag errors or version mismatches
• When setting up a new environment

Operating rules (must follow)

• Never ask for or log secret key contents
• Prefer read-only diagnostics (--help, version, query tip)
• If air-gapped machine, avoid network commands unless explicitly requested
• Output a Compat Report with recommended command style

Docker fallback mode

If cardano-cli is not installed locally, use the wrapper script in this skill folder to run cardano-cli inside Docker (the Cardano node container images include the CLI).
