Use when the user asks to optimize, speed up, tune, or make a Linux system faster — laptops, desktops, or servers. Analyzes hardware, kernel and boot parameters, memory/swap/zram, storage, services, GPU, desktop environment, and network; proposes a prioritized, risk-labeled optimization plan; applies ONLY user-approved changes; verifies every change and documents rollback. Idempotent: re-running on the same system converges, never duplicates config, never re-installs. Analyze-only mode is available. Do NOT use for application code, containers, or website performance.
