Claude Code 2.1.161 drops interactive agent constraint

Anthropic updated its terminal-based AI coding assistant, Claude Code, to version 2.1.161 with bug fixes and CLI improvements. Crucially, the release removes the 'interactive software engineering agent' constraint from the system prompt, shifting the primary guiding instruction to its authorized security testing policy.

// ANALYSIS

Removing the "interactive agent" instruction from the system prompt signals a shift towards direct, utility-first CLI outputs over conversational helper-framing.

• Persona Shift: Eliminating the conversational helper persona allows Claude to respond more directly without unnecessary conversational fluff.

• Security Focus: Removing the interactive agent scope makes the authorized-security-testing policy the primary guiding instruction.

• Improved Resilience: Failed Bash commands no longer cancel co-running parallel tool calls, making multi-task workflows more stable.

• UI & Accessibility Fixes: Animations, prompt shimmers, and the /effort dialog now correctly respect the "Reduce motion" setting.
