GCP self-audit tool that performs security and compliance audits on Google Cloud Platform projects, checking IAM permissions, BYOK (Bring Your Own Key) configurations, and firewall rules. Generates detailed audit reports in Excel format.
Single tool with moderate definition quality. Tool is properly registered with Spring AI MCP and has a clear purpose, but naming lacks action verb clarity, description is below ideal length, parameters lack descriptions, output schema is not documented in the tool definition itself, and no error handling guidance is visible. The tool reads GCP audit data (READ_ONLY), but the definition does not follow production agentic patterns for LLM-driven tool selection and error recovery.
Perform GCP self-audit and generate a report, checking IAM permissions, BYOK, and firewall rules.
Tool name 'GcpAuditTool' does not start with an action verb. Should be 'generate_gcp_audit_report' or 'audit_gcp_project'. LLMs rely on verb-first naming to infer intent without reading descriptions.
Input parameters 'projectId', 'year', 'quarter' lack descriptions. The schema shows types (strings) but provides no guidance on format, constraints, or examples. E.g., is 'year' a 4-digit string like '2025'? Is 'quarter' exactly 'H1' or 'H2', or are variations allowed?
Tool description 'GCP audit tool for generating comprehensive audit reports' is only 64 characters and lacks context on WHEN to use this tool, WHAT it returns, and any prerequisites (e.g., GCP credentials, required IAM roles). LLMs need 10 - 1024 character descriptions that answer: what does it do, when should I call it, what does it return?

Output schema is not documented in the tool definition. The GcpAuditResult DTO shows fields (reportFilePath, auditTime, projectId, year, quarter, status, errorMessage, stackTrace) but this is not visible in the tool registration or MCP schema. LLMs cannot plan downstream calls without knowing what fields the response contains.
No error handling or recovery guidance in tool description. If the audit fails (status='FAILED'), the tool returns errorMessage and stackTrace fields, but there is no documentation on what errors are retryable, what user actions might fix them, or how to recover. E.g., 'If auth fails, ensure GCP service account has audit-reader role.'
Parameter 'quarter' should be constrained as an enum ('H1' | 'H2') rather than a free-form string. Current schema allows any string value, inviting hallucinated invalid inputs like 'H3', 'Q1', 'first-half', etc.
Parameter 'year' should document expected format (e.g., 4-digit string '2025') and valid range (e.g., 2015 - 2025). Without constraints, LLMs may pass '25', '2025-01-01', or 'twenty-twenty-five'.
Tool description does not mention what 'comprehensive audit reports' contain or in what format they are generated. The DTO shows 'reportFilePath' (Excel file), but the tool description does not state this. LLMs cannot decide if this tool is appropriate without knowing the output format and content.
