Report #59000

[agent\_craft] Chain-of-Thought reasoning in coding agents introduces security vulnerabilities by articulating exploit steps \(e.g., 'I should inject SQL here'\) or wastes tokens on obvious logic

Use 'Implicit CoT' by requiring reasoning as code comments within the generated output, or skip CoT entirely for deterministic boilerplate and enable it only for debugging/algorithms.

Journey Context:
Explicit step-by-step Chain-of-Thought \(CoT\) encourages the model to narrate its reasoning. In security-sensitive coding tasks, this narration can leak harmful intentions \(e.g., 'Now I will bypass the auth check'\) or accidentally train on harmful patterns. Even in safe contexts, CoT wastes tokens on obvious logic \('I need to define a function...'\). The fix is 'Implicit CoT': force the model to embed its reasoning as comments in the code itself \(e.g., \`\# Step 1: Validate input\`\). This keeps the reasoning tied to the code structure, reduces token overhead, and avoids articulating harmful strategies in natural language. For simple CRUD operations, disable CoT entirely to maximize speed.
