pi-footer

A compact footer for Pi with two core status rows plus a stable work-status row for active tools and subagents. It shows model and thinking status, working directory, Git state, session name, context usage, provider quotas, and active work.

Preview

Features

• Two aligned, background-free core rows plus a stable work-status row
• Model, thinking level, working directory, Git branch, and /name session display
• Git dirty state plus ahead/behind counts
• Context usage with token counts
• Provider quota lookup with reset countdowns
• Ten-cell segmented progress bars
• Theme-independent usage thresholds: green below 50%, yellow from 50% to below 75%, red at 75% and above
• Truecolor output with a 256-color fallback
• Automatic refresh on startup, model changes, session renames, Git changes, and every five minutes for quotas
• Active parent tool and pi-subagents agent/background counts without layout shifts
• Distinct ● model, threshold-colored ◐ context, and ↳ work-status icons

Install

GitHub

pi install git:github.com/mhjerryjin/pi-footer

npm

pi install npm:@mhjerryjin/pi-footer

Run /reload after replacing another footer extension in an active Pi session.

Usage

Set a session name with Pi's built-in command:

/name feature-work

The footer and terminal tab title update immediately when the name changes:

pi · feature-work

Without an explicit session name, the title falls back to the current project, for example pi · pi-footer.

Most terminal emulators honor the title sequence automatically. VS Code defaults to the foreground process name (node); set this in VS Code User Settings to display the title sent by Pi:

{
  "terminal.integrated.tabs.title": "${sequence}"
}

Work status

While work is active, a compact third row appears automatically:

● model: gpt-5.6-sol │ effort: high │ git: main
◐ context ■■■□□□□□□□ 31% │ weekly ■■■□□□□□□□ 34%
↳ task: bash · 12s │ agents: 1/2 · reviewer running │ bg: 1/4

• task/tasks tracks tools currently running in the parent Pi session.
• agents shows active/total child progress plus active agent labels from the versioned pi-subagents async snapshot, falling back to Fleet counts for older releases.
• bg is active top-level asynchronous subagent work and its configured capacity.
• The row stays reserved but blank while idle, preventing the editor and footer from jumping when work starts or stops.

The pi-subagents integration is optional and uses its versioned in-process event-bus API, so pi-footer has no hard dependency on that package. FleetView remains responsible for per-agent details and controls such as inspect, stop, and steer.

Context refresh after compaction

Immediately after /compact, Pi has no provider-measured token count for the new compacted context. The footer displays a conservative local estimate marked with ~:

◐ context ■■□□□□□□□□ ~14% (~154k/1.1M)

The next assistant response supplies authoritative usage and automatically replaces the estimate without ~.

Configuration

All environment variables are optional:

Variable	Description	Default
PI_MINIMAL_FOOTER_SHOW_SESSION_NAME	Show the explicit session name set with /name	1
PI_MINIMAL_FOOTER_SHOW_CWD	Show the current working directory	1
PI_MINIMAL_FOOTER_SHOW_BRANCH	Show Git branch, dirty state, and ahead/behind counts	1
PI_MINIMAL_FOOTER_SHOW_WORK_STATUS	Reserve and show the work summary row	1
PI_MINIMAL_FOOTER_SET_TERMINAL_TITLE	Update terminal title from the session/project name	1

Accepted false values are 0, false, no, and off (case-insensitive).

Provider support

The extension contains quota adapters for:

• Anthropic Claude Max
• OpenAI Codex
• GitHub Copilot
• Google Gemini CLI
• MiniMax and MiniMax CN
• Kimi Coding
• CommandCode
• OpenCode Go and OpenCode Zen
• OpenRouter

The compact layout prefers a weekly window. When a provider has no weekly window, it displays the provider's most-used available quota or balance window instead.

Credentials and privacy

To query quota endpoints, the extension reads provider-scoped credentials already stored by Pi in ~/.pi/agent/auth.json, standard provider environment variables, and documented provider-specific local credential files. Credentials are used only for the selected provider's request and are not printed or sent to an author-operated service. OpenCode Go/Zen values are local estimates based only on Pi session records.

See SECURITY.md for the complete credential and network behavior.

Platform notes

The implementation uses cross-platform Node.js APIs and is designed for macOS, Linux, and Windows. Git information requires git on PATH. The symbols ●, ◐, ↳, ■, and │ require a modern Unicode-capable terminal; Windows Terminal is recommended on Windows.
