validate_tonel_smalltalk_from_file
AI agents call validate_tonel_smalltalk_from_file to retrieve information from Smalltalk Validator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and analyzes Smalltalk source code from a file to validate it against Tonel format rules. Validation is a read-only, query-like operation that examines code without modifying files, executing code, or triggering side effects. The confidence is slightly reduced (0.85 vs higher) due to the missing description, but the name and server context leave little ambiguity.
From the tool's definition Tool name contains 'validate' and 'from_file', and is part of a validation/linting server (smalltalk-validator-mcp-server). Sibling tools are lint_tonel_smalltalk and validate_smalltalk_method_body, which are clearly static analysis operations.
