Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

🇬🇧 English

A minimal AI coding agent for your terminal. Works with OpenAI, Ollama, and any OpenAI-compatible provider.

🔝 Back to language selector · 🇨🇳 Switch to 简体中文

Get Started

npm install -g min-agent
min-agent setup       # pick a provider and model (interactive)
min-agent             # start chatting
min-agent models      # list the models your provider offers

min is available as a shorter alias with identical functionality (min "...", min serve, ...).

Usage

min-agent "your message"        # start a session and send a message (agent mode)
min-agent ask "your question"   # start in ask mode — web Q&A & search only
min-agent exec "your message"   # one-shot question, then exit
min-agent push                  # shortcut: git commit and push your changes
min-agent --resume <id>         # resume a previous session
min-agent history               # list saved sessions
min-agent -i photo.png "..."    # attach an image
min-agent -m gpt-5.5 "..."      # pick a model for one message
min-agent --provider anthropic "..."   # pick a provider for one message

Modes: agent (default) is the full coding agent — read/write files, run commands, manage config. ask is a separate web-Q&A mode with its own system prompt — only live search (search_web / web_fetch); it skips MCP, skills, rules, and memory. Use /ask / /agent in chat to switch (add --project to keep the choice local to this project). The choice is remembered: min-agent ask, or /ask in a session, means the next plain min-agent also starts in ask mode.

While Chatting

Type / to open the command menu; ↑/↓ selects. On an empty input, ↑/↓ recalls past messages.

| Command | What it does | |---|---| | /new · /sessions | New session · switch between sessions | | /model · /provider | Switch model / provider | | /ask · /agent | Switch to ask (web Q&A) / agent (coding) mode | | /plan | Plan mode — look, don't touch | | /think · /ctx | Thinking intensity · local-model context window | | /memory | Toggle memory or save a note | | /undo · /diff | Undo last turn · show changes so far | | /queue | List, drop or clear messages waiting behind the running turn | | /attach · /mcp · /skills | Attach an image · MCP servers · skills | | /tokens · /help | Usage, reuse & cost · all commands |

The input box stays live while the agent works: press Enter and the message joins a queue that runs in order once the current turn ends (the status bar and spinner show the backlog). Use /queue to inspect it, /queue rm <n> to pull one out, /queue clear to drop them all; Esc cancels the running turn and drops the queue.

Commands that only read state or write config — /permission, /sandbox, /memory, /plan, /ask, /agent, /reload, /rename, and the picker commands given an argument (/model <id>, /think low, /ctx 8k, …) — run immediately even mid-turn, so a permission change applies to the very next tool call instead of waiting behind the whole turn. Everything that mutates the conversation or opens an overlay queues like a message.

Shortcuts: Ctrl+C clears input (press twice to exit) · Shift+Enter / Ctrl+J inserts a newline · Ctrl+V pastes an image · Ctrl+B copies selected text · Ctrl+O expands the tool or thinking row in view · click a tool or thinking block to expand it.

Staying in Control

File edits are auto-approved by default; risky actions always ask. When several actions in one step need approval, they're combined into a single prompt instead of a stack of separate ones. Each prompt offers 允许 / 总是允许 / 拒绝 — choosing 总是允许 remembers that action for the current session, so repeated identical commands or MCP tools won't ask again.

min-agent exec (one-shot) runs more freely by default: edits and ordinary commands don't ask — only genuinely destructive commands (deleting files, dropping/truncating databases, disk-wiping, git reset --hard, etc.) still prompt. Pass --permission or --yes to override. Thinking and tool calls print as a single summary line each.

min-agent permission                 # show current setting
min-agent --permission ask           # confirm before risky actions
min-agent --permission accept-edits  # auto-approve file edits (default)
min-agent --permission allow-all     # auto-approve everything — use with care
min-agent sandbox workspace          # only allow changes inside this folder

On Windows, OS-level command isolation (macOS seatbelt / Linux bwrap) is unavailable: strict refuses shell commands; workspace still blocks file tools outside the folder. Shell commands prefer Git Bash when installed.

Off by default. Turn it on to keep facts across sessions:

min-agent memory on             # enable (writes config)
min-agent memory add "prefer bun"

In chat: /memory on|off toggles, /memory lists notes, /memory some text saves one.

Configuration

min-agent ships with a free preset OpenRouter provider (openrouter/free), so it works out of the box. Run min-agent setup any time to switch to your own provider:

min-agent setup        # add a provider (interactive; OpenAI / Ollama / any OpenAI-compatible endpoint)
min-agent provider     # show the active provider and any you've added
min-agent models       # list the models your provider offers

min-agent provider <name> switches the active provider (add/edit/remove go through min-agent setup).

Adding an OpenCode Go / OpenCode Zen endpoint (e.g. https://opencode.ai/zen/go/v1) is detected during setup, and every request then carries the x-opencode-session header that endpoint requires — one stable id per conversation. Use --opencode-session / --no-opencode-session to force it on or off (e.g. for a gateway that proxies OpenCode Go under another host).

The built-in OpenRouter preset (openrouter/free) is never written to disk. Set MIN_AGENT_BUILTIN_API_KEY to override it with a key of your own. While the preset is active it can't be edited or switched away from, but adding your own provider takes over automatically; MIN_AGENT_NO_BUILTIN_PROVIDER=1 disables it outright.

Settings live in ~/.min-agent/config.json (global). Per-project settings go to ~/.min-agent/sessions/<project-key>/config.json (auto-created; nothing is written inside the project directory).

Extending It

  • MCP servers — connect external tools: min-agent mcp -h
  • Skills — reusable instructions the agent loads on demand: min-agent skills -h
  • Project rules — add AGENTS.md or RULES.md to your project; global rules go in ~/.min-agent/rules.md or ~/.min-agent/AGENTS.md

API Access

min-agent serve starts a local HTTP API for other apps to talk to. Reference: docs/API.md

🇨🇳 简体中文

一款可在终端里运行的极简 AI 编程助手,支持 OpenAI、Ollama 以及任何兼容 OpenAI 接口的服务商。

快速上手

npm install -g min-agent
min-agent setup       # 选择服务商与模型(交互式)
min-agent             # 开始对话
min-agent models      # 查看当前服务商可用的模型

min 是等价的短命令,功能完全相同(min "..."、min serve 等)。

基本用法

min-agent "你的消息"            # 进入交互会话并立即发送消息(agent 模式)
min-agent ask "你的问题"        # 以 ask 模式进入——仅联网问答与搜索
min-agent exec "你的消息"       # 单次提问后自动退出
min-agent push                  # 快捷指令:git 提交并推送代码
min-agent --resume <id>        # 恢复之前的会话
min-agent history              # 查看已保存的会话
min-agent -i photo.png "..."   # 为一条消息附带图片
min-agent -m gpt-5.5 "..."     # 为一条消息指定模型
min-agent --provider anthropic "..."   # 为一条消息指定服务商

会话模式:agent(默认)是完整编码智能体——读写文件、执行命令、管理配置;ask 是独立的联网问答模式,使用专门的系统提示词,仅保留联网搜索(search_web / web_fetch),不加载 MCP、skills、规则与记忆。对话中用 /ask / /agent 随时切换(加 --project 只对当前项目生效)。切换会被记住:min-agent ask 或在会话里 /ask 之后,下次直接运行 min-agent 也以 ask 模式启动。

对话中的操作

输入 / 弹出命令菜单,用 ↑/↓ 移动高亮;输入框为空时,↑/↓ 翻看之前消息。

| 命令 | 作用 | |---|---| | /new · /sessions | 新建会话 · 切换会话 | | /model · /provider | 切换模型 / 服务商 | | /ask · /agent | 切换 ask(联网问答)/ agent(编码)会话模式 | | /plan | 计划模式——只看不改 | | /think · /ctx | 思考强度 · 本地模型上下文窗口 | | /memory | 开关记忆,或保存一条 | | /undo · /diff | 撤销上一轮 · 查看已产生的改动 | | /queue | 查看、移出或清空排在当前任务后面的消息 | | /attach · /mcp · /skills | 附加图片 · MCP 服务 · 技能 | | /tokens · /help | 用量、复用与费用 · 全部命令 |

任务执行时输入框依然可用:按 Enter 会把消息排进队列,当前任务结束后按顺序执行(运行提示行显示排队数量)。/queue 查看队列,/queue rm <序号> 移出一条,/queue clear 全部清空;Esc 取消当前任务,并丢弃排队消息。

只读取状态或只写配置的命令——/permission、/sandbox、/memory、/plan、/ask、/agent、/reload、/rename,以及带参数的选择类命令(/model <id>、/think low、/ctx 8k 等)——在任务执行中也会立即执行:改完确认模式马上对下一次工具调用生效,不必等整轮结束。会改动对话内容或打开浮层的命令则和消息一样排队。

快捷键:Ctrl+C 清空输入(连按两次退出)· Shift+Enter / Ctrl+J 换行 · Ctrl+V 粘贴图片 · Ctrl+B 复制选中的文本 · Ctrl+O 展开视图中间的工具/思考行 · 点击工具或思考块可展开收起。

掌控风险

文件修改默认自动批准,危险操作仍会询问;同一步里有多个操作需要授权时,会合并成一个弹窗逐条列出,而不是弹出一堆。弹窗提供 允许 / 总是允许 / 拒绝 三个选项——选「总是允许」会在本次会话内记住该操作,之后重复的相同命令或 MCP 工具不再询问。

min-agent exec(单次执行)默认更放手:文件修改和普通命令都不询问,只有真正具破坏性的命令(删除文件、drop/truncate 数据库、抹盘、git reset --hard 等)才会询问。加 --permission 或 --yes 可覆盖此默认。思考过程和工具调用各占一行摘要,不展开全文。

min-agent permission                 # 查看当前设置
min-agent --permission ask           # 有风险操作前先询问
min-agent --permission accept-edits  # 仅自动批准文件修改(默认)
min-agent --permission allow-all     # 自动批准所有操作——请谨慎使用
min-agent sandbox workspace          # 仅允许修改当前文件夹内内容

Windows 上没有 macOS/Linux 那种命令级隔离:strict 会拒绝执行 shell;workspace 仍会限制文件工具写到目录外。装了 Git Bash 时优先用它跑命令。

记忆

默认关闭。想让偏好跨会话保留时再打开:

min-agent memory on             # 开启记忆(写入配置)
min-agent memory add "prefer bun"

对话里用 /memory on|off 开关,/memory 查看,/memory 一段话 保存一条。

配置

min-agent 不附带任何密钥,首次运行会引导你走 min-agent setup:

min-agent setup      # 添加服务商(交互式;OpenAI / Ollama / 任意 OpenAI 兼容接口)
min-agent provider   # 查看当前服务商,以及你已添加的服务商
min-agent models     # 查看当前服务商可用的模型

min-agent provider <name> 切换当前服务商(增、删、改走 min-agent setup)。

添加 OpenCode Go / OpenCode Zen 接口(如 https://opencode.ai/zen/go/v1)时会自动识别,之后每次调用都会带上该接口要求的 x-opencode-session 头,同一会话固定一个 id。用 --opencode-session / --no-opencode-session 可强制开启或关闭(例如换了域名的自建网关)。

min-agent 内置一个免费的 OpenRouter 预设(openrouter/free),开箱即用,该预设不会写入配置文件。如果要换成自己的 key,设置 MIN_AGENT_BUILTIN_API_KEY 即可覆盖默认 key。预设生效期间不可编辑、不可切换或删除,但添加自己的服务商后会自动接管;MIN_AGENT_NO_BUILTIN_PROVIDER=1 可彻底关闭预设。

配置保存在 ~/.min-agent/config.json(全局生效)。项目级配置保存在 ~/.min-agent/sessions/<project-key>/config.json(自动创建,不会在项目目录里生成任何文件),仅对该项目生效。

扩展能力

  • MCP 服务:连接外部工具与数据源,min-agent mcp -h
  • 技能(Skills):由 agent 按需加载的可复用指令集,min-agent skills -h
  • 项目规则:在项目里添加 AGENTS.md 或 RULES.md;全局规则写入 ~/.min-agent/rules.md 或 ~/.min-agent/AGENTS.md

API 接入

min-agent serve 可启动本地 HTTP API 服务,供其他应用调用。完整说明见 docs/API.md
