[synthesis] Agent pivots entire strategy on transient failure instead of retrying — timeout treated as logical error

Classify tool failures at the tool layer into retryable \(timeout, 429, 5xx, network error\) vs logical \(404, schema violation, permission denied\). For retryable failures, implement exponential backoff retry without exposing the failure to the agent's reasoning chain. Only surface logical failures to the agent for strategy pivots.

Journey Context:
When an agent gets a 429 or connection timeout, it often interprets this in its reasoning as 'my approach is wrong' and pivots to a completely different strategy — abandoning valid reasoning that led to the correct call. This wastes prior computation and can send the agent down a worse path. The root cause is that most agent frameworks surface all tool errors uniformly to the LLM's reasoning context. The LLM then does what it's trained to do: reason about the error and adapt. But for transient failures, adaptation is wrong — persistence is correct. The synthesis insight: the agent's reasoning layer and the tool execution layer have different failure models, and conflating them is a category error. The fix borrows from distributed systems: the tool layer should handle transient failures with retries \(with backoff\), and only escalate logical failures to the reasoning layer. This is the circuit-breaker pattern applied to agent-tool boundaries.
