Inside Claude Code's System Prompt: Reversibility Tiers, Anti-Overengineering & Failure Recovery

This article dissects the system prompt of Anthropic's Claude Code terminal agent, revealing how its design uses a two-tier reversibility framework, anti-overengineering rules, a six-step failure recovery protocol, tool-use boundaries, and adversarial-input defenses to constrain autonomous coding behavior rather than guide code generation.
