Report #54772

[agent\_craft] Verbose JSON schemas for simple tools consume excessive context tokens

For tools with simple flat arguments, use ReAct-style string format \`Action: tool\_name\[input\]\` instead of full JSON schema; validate with regex

Journey Context:
JSON schemas are descriptive but token-heavy \(braces, quotes, newlines\). For simple tools like \`read\_file\` or \`grep\`, the ReAct format \(Action/Action Input\) is proven in research to be token-efficient and sufficient. This saves 30-50% tokens per tool call, crucial for long agent sessions. The tradeoff is that nested structures still need JSON.
