validate_tonel_smalltalk
AI agents call validate_tonel_smalltalk 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.
Validation and linting tools perform static code analysis without modifying data, executing code, or having side effects. The tool takes Smalltalk source code as input and returns validation results—a classic read-only operation. No data is created, deleted, or modified, and no external operations are triggered.
From the tool's definition Tool name 'validate' and server purpose of 'validating and linting Tonel formatted Smalltalk source code' indicate a static analysis function.
