v2.157.0

Code Simplifier Safety Constraints

• Make code-simplifier an analysis-only agent — produces suggestions for human review, never applies changes directly
• Require highest reasoning tier (opus/pro/o3) — non-thinking models risk knowledge loss
• Remove write/edit tool permissions as a hard gate
• Add structured output format with Preserved/Risk/Confidence fields per finding
• Add classification system (safe/careful judgment/almost-never-simplify)
• Add knowledge preservation rules for institutional memory, decision comments, disabled-code rationale
• Add decorative emoji removal as simplification target (functional UI emojis excluded)
• Add simplification-debt to pulse priority order (priority 8) with 10% concurrency cap
• Add Codacy maintainability grade as priority boost signal
