`bawbel report <path>`	Scan a component and show a full remediation guide with fix guidance per finding
`bawbel creds <path>`	Focused scan — hardcoded credentials and secret exposure only
`bawbel chain <path>`	Focused scan — unsafe agent delegation chains only
`bawbel ssc <url>`	Fetch and scan an MCP server-card for AVE vulnerabilities without starting the server
`bawbel scan-server-card <url>`	Alias for `ssc`
`bawbel conform <target>`	Score an MCP server manifest against the MCP specification (A+ to F grade)
`bawbel scan-conformance <target>`	Alias for `conform`
