Automation summary

• root_cause: The MCP tool error messages for "400 invalid parameter value" were not specific enough to help users understand what parameter was wrong or how to fix it. Additionally, the cloud functions skill documentation lacked practical examples of using npm dependencies, which made it difficult for users to implement real-world use cases like using lodash for data processing.
• changes:

1. mcp/src/tools/functions.ts: Enhanced buildFunctionOperationErrorMessage function to detect "invalid parameter value" errors and provide specific guidance with a checklist of common parameter issues (function name format, runtime version, function type, environment variable types, functionRootPath requirements).
2. config/source/skills/cloud-functions/SKILL.md: Added a new "Using npm dependencies" section with a complete working example showing how to use lodash for order data processing, including package.json configuration, function code, deployment command, and invocation example with test data.

• validation: All 10 regression tests pass (tests/skill-quality-standards.test.js, tests/build-skills-repo.test.js, tests/build-compat-config.test.js). TypeScript compilation passes for th
