[agent\_craft] Composite tool definitions bloat token usage and confuse function boundaries

Design 'Atomic Tools' \(read\_file, write\_file, run\_command\) and let the LLM compose them via Chain-of-Thought reasoning, rather than creating monolithic 'edit\_file\_with\_context' tools.

Journey Context:
Tempting to create high-level tools like 'refactor\_class' to save reasoning steps. But this bakes business logic into the tool schema, making it brittle. Atomic tools mirror Unix philosophy: do one thing well. The LLM handles orchestration via ReAct-style loops. Tradeoff: more LLM calls/turns, but better observability and easier debugging. Also reduces tool description token count significantly.
