[agent\_craft] Agent wastes 40% of token budget on unnecessary reasoning for deterministic tool calls

Skip CoT for deterministic, schema-validated tool invocations \(e.g., 'read\_file' where arguments are validated\); use CoT only for synthesis, planning, or when tool output requires interpretation. Implement a 'fast path' for validated tool schemas.

Journey Context:
CoT is expensive \(2-3x token cost\) and increases latency. Many agents force 'Thought: \[reasoning\]' on every step, which is wasteful for deterministic lookups where the action is obvious from the query. The distinction: if the LLM's reasoning is just paraphrasing the user's request \(trivial\), skip it. If the LLM needs to decide between multiple tools or interpret previous results \(non-trivial\), use CoT. This optimizes latency without hurting capability.
