Install & Important Note

pi install npm:pi-cc-header

Takes effect on your next session (window, same below) or /reload. Please read this document in full, especially the Reset, disable & uninstall section, to ensure proper use of this extension.

This extension follows Pi's runtime config directory. If you use a custom agent dir such as ~/.config/pi/agent via PI_CODING_AGENT_DIR, pi-cc-header reads and writes the active settings.json there instead of assuming ~/.pi/agent.

Note: switching to a new config directory does not migrate your existing /hc etc. settings — reconfigure them in the new location, or copy your old settings.json over.

If your Pi config is managed declaratively or lives on a read-only filesystem, set:

{
  "ccHeader": {
    "readOnlyConfig": true
  }
}

With ccHeader.readOnlyConfig=true, the extension will not try to write settings.json at startup or when running header commands. Visual changes still apply for the current session, but they are not persisted, and /hcl becomes unavailable until you remove the flag declaratively.

Features

  • 14-frame Pi logo animation, adjustable speed (25/50/75/100 ms)
  • 9-color palette: Anthropic brand orange, Clawd crab red, and more
  • IBM-style horizontal stripes
  • Minecraft-style pixel theme and 4-level 24-bit true-color gradient
  • Version number coloring
  • Startup status bar: version, model, thinking level, skills (with pkg skills count), prompts, extensions (with uninstalled extension residue marker), cwd, and AGENTS.md state marker
  • Customizable slogan displayed in the header

Commands

Command Description Takes effect
/hc c/a/r/o/y/g/w/b/p / /hc Set logo color or show current with color key table Immediate
/hi Toggle IBM-style on/off Immediate
/hm Toggle Minecraft-style on/off Immediate
/hsp / /hsp Set / show animation speed (25/50/75/100) Immediate
/hv / /hv <all|pi|off> Cycle or set version label color Immediate
/hps Toggle pkg skills visibility (6 skills / 6/7 skills) Immediate
/hs / /hs / /hs -c / /hs -d Set / toggle / toggle color / delete slogan (max 85 chars) Immediate
/hdf Reset to developer defaults Immediate
/htg Enable / disable pi-cc-header Next session
/hcl Clear all pi-cc-header config from settings.json Immediate

Reset, disable & uninstall

  • Use /hdf to reset all settings to developer defaults (Clawd crab red). Changes take effect immediately. This does not save your current config — you will need to reconfigure from scratch.
  • Disabling pi-cc-header with /htg locks all style commands (except /htg itself) to prevent blind configuration. Run /htg again to re-enable with your previous config — changes take effect the next session.
  • Before uninstalling, run /hcl to clear all pi-cc-header keys from settings.json and remove the header. Then pi uninstall npm:pi-cc-header for a clean removal.

Logo animation adapted from pi.dev/install.sh.

Thanks to @hacxy — Fixed logo animation flicker & settings.json data loss protection.

Thanks to @ReStranger — Fixed config path resolution to follow custom Pi config directories; added read-only config mode (ccHeader.readOnlyConfig) for NixOS and read-only filesystems.

Thanks to @mediocrebaby — Fixed config path resolution for Windows compatibility.

安装与提醒

pi install npm:pi-cc-header

安装后在 下一次会话(窗口,下同)/reload 生效。请务必完整阅读本文档,特别是重置、禁用与卸载小节,以确保您正常使用本扩展。

本扩展会跟随 Pi 当前实际使用的配置目录。如果您通过 PI_CODING_AGENT_DIR 使用 ~/.config/pi/agent 之类的自定义 agent 目录,pi-cc-header 会在该目录下读写当前生效的 settings.json,不会再假定路径一定是 ~/.pi/agent

注意:切换到新的配置目录后,原有的 /hc 等自定义设置不会自动迁移,需要在新目录中重新设置,或手动复制旧的 settings.json

如果您的 Pi 配置由 Nix / Home Manager 等声明式工具管理,或者配置目录本身是只读文件系统,请加入:

{
  "ccHeader": {
    "readOnlyConfig": true
  }
}

启用 ccHeader.readOnlyConfig=true 后,扩展在启动和执行头部命令时都不会再尝试写入 settings.json。界面变更仍会在当前会话内生效,但不会持久化;同时 /hcl 也会不可用,需通过声明式配置移除该字段后再卸载。

功能

  • 14 帧 Pi logo 动画,动画速度可调(25/50/75/100 ms)
  • 九色调色板:Anthropic 品牌橙、Clawd 螃蟹红等
  • IBM 风格水平横线
  • Minecraft 风格像素主题,4 级 24-bit 真彩色渐变
  • 版本号颜色设定
  • 启动状态栏:版本、模型、思考级别、技能统计(含随包 skills 统计)、提示词模板统计、扩展统计(含已卸载扩展残留标记)、当前目录,以及 AGENTS.md 状态标记
  • 可定制标语

命令

命令 说明 生效方式
/hc c/a/r/o/y/g/w/b/p / /hc 设置 logo 颜色或显示当前颜色及色键表 即时生效
/hi 开关 IBM 横线 即时生效
/hm 开关 Minecraft 风格 即时生效
/hsp / /hsp 设置 / 显示动画速度(25/50/75/100) 即时生效
/hv / /hv <all|pi|off> 循环或设定版本号颜色模式 即时生效
/hps 切换随包 skills 可见性(6 skills / 6/7 skills) 即时生效
/hs <文字> / /hs / /hs -c / /hs -d 设置 / 开关 / 切换颜色 / 删除标语(最长 85 字符) 即时生效
/hdf 恢复开发者默认配置 即时生效
/htg 启用 / 禁用 pi-cc-header 下一次会话生效
/hcl 清除 settings.json 中所有 pi-cc-header 配置 即时生效

重置、禁用与卸载

  • 使用/hdf可将用户配置恢复为开发者默认配置(Clawd 螃蟹红),更改即时生效,此命令不会保存用户配置,重置后用户需重新进行配置
  • 使用/htg禁用 pi-cc-header 后,所有样式命令会被锁定无法使用(/htg除外),防止盲操配置。重新执行 /htg 即可恢复禁用前的配置。更改将在下一次会话生效
  • 执行 /hcl 将清空 settings.json 中所有 pi-cc-header 相关的配置项并移除头部,用于卸载本扩展前的清理——先 /hcl,再 pi uninstall npm:pi-cc-header,无残留。
