[synthesis] Agent creates cascading syntax errors by failing to handle nested encodings

Use structured tool outputs \(like JSON objects\) instead of raw strings wherever possible, and enforce strict schema validation on both inputs and outputs to catch encoding errors at the tool boundary.

Journey Context:
An agent writes a string to a file containing unescaped quotes. When it later reads this file to pass it to an API, it fails. The agent tries to fix the script, but its fix introduces more unescaped characters because it is reasoning about the code as flat text rather than as a nested data structure. The synthesis is that agents lack a native representation of nested encoding contexts \(e.g., JSON inside YAML inside Python\). Schema validation at the tool boundary catches encoding errors immediately, preventing them from cascading into corrupted files.
