codeql_database_create: improve error message for unrecognized kebab-case parameter names #212
Description
Context
Sub-issue of #208 — Area 2: database_create uses kebab-case params with unhelpful rejection message
Problem
The codeql_database_create tool accepts source-root (kebab-case) but rejects sourceRoot (camelCase) with:
Your input to the tool was invalid (must NOT have additional properties)
The error does not identify which property was rejected. LLM agents commonly default to camelCase JSON keys, making this a frequent first-invocation failure.
Requirements
- Include the name of the unrecognized property in the error (e.g.
unknown property 'sourceRoot' — did you mean 'source-root'?) - Consider accepting camelCase aliases for kebab-case parameters
