[synthesis] Agent writes files to wrong directory without error because OS returns success code

Implement semantic validation checks after file operations. Instead of just checking if the tool returned exit code 0, force the agent to run a subsequent command verifying the absolute path and file contents \(e.g., readlink -f and head\) against the expected target before proceeding.

Journey Context:
Agents rely heavily on exit codes to determine success. If an agent calculates an incorrect but syntactically valid path \(e.g., /tmp/ instead of /app/data/\), the OS returns 0 on write. The agent assumes success and moves on. Downstream pipelines then read the empty correct directory and fail or corrupt data. Relying on OS exit codes is a semantic gap; the OS validates permissions and structure, but the agent must validate intent and semantics. Without this, a minor path miscalculation cascades into silent data loss.
