Restructures bloated instruction files in bulk to shrink always-loaded context and restore agent performance. Use when CLAUDE.md, AGENTS.md, Cursor rules, or other instruction files have grown too large (200+ lines, 40k+ chars), when agent performance has degraded due to bloated context, or when the user asks to audit, restructure, slim down, or clean up their instruction files. For a single small edit to an instruction file, use instruction-guardian instead.
