macOS / Windows 只读存储分析助手（自动识别系统）。扫描整机磁盘占用，找出 占空间大户，把每一项分成 🟢可自动清理 / 🟡需人工判断 / 🔴谨慎清理 三级并给出 可执行处置方案，生成排版精美、可折叠、命令可一键复制的交互式 HTML 报告，并可 起本地服务在网页上一键删除（移废纸篓/直接删）。扫描全程只读。务必在以下场景 使用：用户说"存储分析""磁盘满了""C盘/硬盘满了""空间不够""清理空间" "清理磁盘""占空间""哪些东西占地方""帮我看看存储""看一下电脑存储/空间" "存储空间""电脑空间不够""内存满了/不够/不足""看下内存/存储"（中文口语里 "内存"常指存储空间）"storage analysis""disk cleanup""清缓存""磁盘清理"； 或用户抱怨电脑没空间、想知道什么东西吃硬盘、想要清理建议时。注意：若用户明确 指运行内存/RAM（如"哪个进程吃内存""内存占用高"想看活动监视器），那是 RAM 不是存储，不属于本 skill。

KC-Chat group autopilot autonomous mode full protocol. Read ONLY when user says "start autopilot/autonomous mode", or about to call `autopilot_start` / `autopilot_pause` / `autopilot_stop` / `autopilot_status`, or on receiving `[AUTOPILOT_TICK]` / `[AUTOPILOT_PAUSED]` / `[AUTOPILOT_BUDGET_EXHAUSTED]` system messages. Covers: startup flow, Leader LOOP, Worker behavior, shared memory schema, cooldown compatibility, autonomy contract (autonomyLevel/budget), Watchdog fallback, `[AUTOPILOT_TICK]` forced action rules, safety constraints.

Behavioral guidelines to reduce common LLM coding mistakes. Use when writing, reviewing, or refactoring code to avoid overcomplication, make surgical changes, surface assumptions, and define verifiable success criteria.
