[agent\_craft] Chain-of-thought causing 'overthinking' latency for simple read-only operations

Implement adaptive reasoning: disable CoT for read-only tools \(file read, grep\) by using direct tool generation with temperature 0; enable CoT only for write operations or error recovery scenarios.

Journey Context:
Chain-of-Thought \(CoT\) improves accuracy on complex reasoning tasks but incurs significant token costs \(often 2-3x the output tokens\) and latency. For simple, deterministic read operations \(e.g., \`cat file.txt\` or \`grep pattern\`\), CoT provides no benefit—the result is either correct or not—yet the model wastes tokens 'thinking' about whether to read the file. The pattern is to implement an 'adaptive reasoning' router in the agent loop: classify the operation type before calling the LLM. For read-only, idempotent queries, use a fast, no-CoT prompt \(direct tool generation with temperature 0\). For destructive writes, multi-step planning, or error recovery scenarios, escalate to the full CoT-enabled prompt. This cuts average token consumption by 30-50% on read-heavy tasks without sacrificing reliability on complex edits.
