Report #93143

[agent\_craft] Agent fails to chain multiple tool calls correctly, calling tools in wrong order or omitting required steps

Include 1-2 concrete examples of successful multi-step tool use sequences \(including the thought process if using ReAct\) directly in the system prompt, showing the exact JSON/XML format for each step. This is more reliable than zero-shot for >2 step operations.

Journey Context:
Zero-shot tool use works for single actions \(e.g., 'read file'\), but fails for complex workflows like 'search codebase, then read specific file, then edit it'. The model hallucinates tool names or skips the search step. The alternative is to rely on the model's 'planning' capability, but this is unreliable without examples. Research shows that few-shot examples for tool use dramatically reduce error rates in multi-step reasoning \(the 'Toolformer' and subsequent agent papers\). The examples must include the interleaved 'thought' and 'action' if using ReAct, or just the sequence if using Plan-and-Execute. Crucially, these examples should be in the system prompt, not the user prompt, to establish the 'protocol' for the agent.
