Report #94399

[frontier] Agents fail on complex multi-step reasoning tasks \(math, planning\) that require deep analysis before tool use

Use Claude 3.7's extended\_thinking mode with budget\_tokens parameter; set thinking type to enabled and allocate 20-40% of context window to thinking tokens; parse the thinking content block separately from the final response to audit reasoning chains

Journey Context:
Standard mode rushes to tool calls with flawed reasoning; extended thinking forces the model to work through logic chains explicitly before responding, drastically improving accuracy on complex coding and analysis tasks at the cost of latency and token usage.
