Leftovers — clean up processes and caches coding agents leave on a Mac
清理编程 Agent 遗留的进程与缓存。 Clean up processes and caches left by coding Agents.
Show HN https://github.com/arpwal/leftovers — MIT 免费 macOS 菜单栏应用：按 footprint（RAM+压缩+swap）找出 agent / 应用留下的 dev server、MCP、git worktree、LaunchAgent 与可重建缓存，安全清理。与 Grok Bot / Claude Code / Cursor Agent 等本机旁路相邻；本条是工具笔记，不替你在本机执行清理。 Adjacent to local Grok Bot / Claude Code / Cursor Agent workflows; this is a tool tip — it does not run cleanup on your machine for you.
Leftovers 是开源 macOS 菜单栏工具（MIT）。README 写：coding agent 会话常留下 dev server、各自一份 MCP、git worktree 和定时任务；Activity Monitor 按内存排序时，已经换到 swap 的泄漏几乎看不见。Leftovers 读每个进程的 footprint（RAM + 压缩 + swap），列出 likely leaks、按 agent 会话归类的占用、可安全移除的 worktree（含 GitHub squash-merge 已合但本地还在的），以及可重建的开发者缓存（Xcode / npm / Docker 构建缓存等，不碰你的代码和数据库 volume）。也有 CLI：`leftovers --report` / `--json` / `--clean`。Show HN item 49861159。本站收成「工具笔记」：给跑本机 agent（含 Grok Bot 相邻栈）时清桌面用，不是云端 Bot 本身。 Leftovers is an open-source macOS menu-bar tool (MIT). The README says coding-agent sessions often leave behind dev servers, per-session MCP copies, git worktrees, and scheduled jobs; Activity Monitor sorts by RAM, so a leak already swapped out barely shows. Leftovers reads each process’s footprint (RAM + compressed + swap), lists likely leaks, memory by agent session, worktrees that are safe to remove (including ones squash-merged on GitHub that local git still keeps), and rebuildable developer caches (Xcode / npm / Docker build cache, and more — not your code or database volumes). CLI too: leftovers --report / --json / --clean. Show HN item 49861159. This library lists it as a tool tip for cleaning a local agent desk (including Grok Bot-adjacent stacks) — not the cloud Bot itself.
为什么推荐Why we recommend it 收录理由：agent 本机残留是真实痛点，菜单栏 + CLI 可核对。边界：只支持 macOS；清理动作不可逆，受保护进程会拒绝；本站未在你的 Mac 上安装或代清。 Listing rationale: leftover local agent processes are a real pain; menu bar + CLI are checkable. Boundary: macOS only; cleanup is irreversible and protected processes are refused; this site did not install or clean on your Mac.

左列是 README / Show HN 对得上的事实。右列说明为什么放在 Cases 工具笔记，而不是当成「官方 Grok Bot 插件」。 Left column: what the README / Show HN actually say. Right column: why it sits as a Cases tool tip — not an official Grok Bot plugin.

本站未代装、未代清。清理不可逆，点之前自己看列表。 This site did not install or clean for you. Cleanup is irreversible — read the list first.
先看 https://arpwal.github.io/leftovers/ 与 GitHub README，确认 MIT、macOS、footprint / agents / worktrees / caches 几块对得上你的痛点。 Read https://arpwal.github.io/leftovers/ and the GitHub README first; confirm MIT, macOS, and the footprint / agents / worktrees / caches sections match your pain.
README：拖进 Applications，或 `brew install --cask arpwal/tap/leftovers`。本站不代装。装好后先看 Overview / Likely Leaks，别一上来 --clean。 README: drag into Applications, or brew install --cask arpwal/tap/leftovers. This site does not install it. After install, read Overview / Likely Leaks before any --clean.
优先 likely leaks 与已合并且无改动的 worktree；缓存类只清作者标明可重建的。生产目录、未提交 worktree、Docker volume 别碰。 Prefer likely leaks and already-merged worktrees with no local changes; only clear caches the author marks rebuildable. Leave production folders, dirty worktrees, and Docker volumes alone.
