[agent\_craft] Zero-shot tool calling schema ambiguity

Provide 1-2 few-shot examples of correct tool calls \(input -> selected tool \+ parameters\) in the system prompt when introducing new or complex tools.

Journey Context:
Zero-shot tool selection fails when parameter schemas overlap \(e.g., search\_code vs search\_docs with similar signatures\) or when parameter extraction requires implicit context \(relative paths vs absolute\). Pure schema descriptions lack tacit knowledge about when to prefer one tool over another. Few-shot examples clarify decision boundaries without requiring exhaustive parameter documentation. Counter-intuitive: More than 3 examples causes overfitting to example specifics \(path formats, naming conventions from examples leak into production calls\). Sweet spot is 1 example for simple tools, 2 for complex multi-parameter tools. Examples must be syntactically perfect - malformed examples teach the agent to replicate syntax errors.
