[synthesis] Agent abandons specific API tools and falls back to generic shell commands as tool schemas grow complex

Monitor the ratio of generic tool usage \(e.g., bash, write\_file\) to specific tool usage \(e.g., git\_commit, sql\_query\). A rising ratio of generic tool calls is a leading indicator that the agent is confused by the specific tool schemas and is degrading to brute-force methods.

Journey Context:
Developers add more parameters and enums to tool schemas to make them smarter. However, LLMs struggle with complex JSON schemas, especially when multiple tools share similar parameters. The agent silently pivots to using a generic bash command to achieve the goal because it is easier to construct the string. The task succeeds, but you lose idempotency, safety guardrails, and auditability. The degradation is silent because the outcome is correct, but the operational risk has skyrocketed.
