[frontier] How to automatically fix tool schemas when agents repeatedly fail to call them correctly?

Implement a feedback loop that captures tool call failures \(validation errors, exceptions\), uses an LLM to analyze the mismatch between the agent's attempted arguments and the actual schema requirements, and automatically proposes schema patches \(adding descriptions, adjusting types, adding examples\) that are validated before deployment.

Journey Context:
Hardcoded tool schemas often drift from actual usage patterns or lack descriptive metadata for the LLM. When agents fail \(e.g., sending a string where an object is expected\), traditional systems just log the error. Instead, treat these failures as training data for the schema itself. By diffing the 'attempted args' against the 'valid schema', you can generate natural language explanations of what went wrong and update the schema's 'description' or 'examples' fields. This is 'self-healing' tool definitions. Alternative: manual schema updates \(too slow\). Risk: adversarial inputs causing bad schema mutations; mitigate with human-in-the-loop for critical tools.
