Office-agent skill inventory & health check. Scans any skills directory, measures size and context-token footprint, detects duplicates, and classifies skills into used / protected / closeable / manual-review buckets. Reverse-dependency scanning locks every skill referenced by automations, hooks or plugins. Read-only by default: two disclosed, consent-gated write targets — `--overrides --apply --yes` (programmatic close on platforms like WorkBuddy; dry-run without --yes) and `--set-lang` (saves the report language preference to ~/.workbuddy/skill-inventory.json) — plus one disclosed backup artifact: a timestamped ~/.workbuddy/settings.json.bak.<ts> safety copy created before the close write, path printed to the user. Report language: auto (default; the Agent decides per conversation language) / zh / en; one-off override via --lang; JSON output is always English-keyed. No network access, no subprocesses. English docs: SKILL.en.md. 办公型 Agent 通用的技能库盘点与效能体检。扫描任意技能目录，统计数量/体积/上下文 token 占用， 识别重复与近似技能，并按「有使用记录/受保护/可关闭候选/需人工确认」四档给出保守建议；反向依赖 扫描会锁定被自动化/Hook/插件引用的技能。默认只读，两处写路径目标均需显式授权：`--overrides --apply --yes`（仅 WorkBuddy 等可关平台，缺 --yes 只做预览）与 `--set-lang`（把报告 语言偏好写入 ~/.workbuddy/skill-inventory.json）；另有一份已披露的备份工件——关闭写入前在 settings.json 旁生成带时间戳的 settings.json.bak.<ts> 安全副本，路径会打印给用户。语言设置三选一： auto（默认，Agent 按对话语言 决定）/ zh / en；--lang 仅本次运行覆盖；--json 输出恒为英文键。无网络、无子进程。 英文文档见 SKILL.en.md。
