pisesh

English | 한국어

Bookmark, search, and resume pi coding-agent sessions with a fast keyboard-driven TUI.

pi --resume lists every session you ever started. After a week that's 50+ entries with no titles, no tags, and no order, so you just scroll and hope. pisesh adds what was missing: ⭐ favorites, instant search, and a [NOW] badge for the session you're attached to.

Terminal walkthrough

What the TUI looks like, screen by screen. The data below is made up, not real sessions.

Main list. The highlighted row is the current selection, and Tab cycles through the tabs. The green [NOW] badge marks the pi session you launched from, and the cyan ✎ marks a session you renamed yourself. CJK titles stay column-aligned:

e renames a session. The first user prompt makes a poor title for a thread you keep coming back to, so press e to set your own. It's saved as an override (the session jsonl is never touched) and the session gets a ✎ marker in the list:

p re-points the working directory through an arrow-key directory browser. This is the cwd pi actually cds into on resume, and it's also what the Here tab filters on. Press s to lock in the highlighted directory:

The Here tab shows only sessions whose effective cwd matches the directory you launched pisesh from. Inside a project you see just that project's threads, without scrolling past your home-dir scratch sessions.

Why pisesh

Pi accumulates sessions across many working directories: your home, several project dirs, scratch tmux panes. The built-in resume picker is roughly alphabetical and forgets context. After a few weeks:

• You can't tell which session was "the one where you fixed the auth bug"
• You can't pin the 3-4 long-running threads you keep going back to
• You re-open the wrong session and pollute it with unrelated context
• You waste time searching by timestamp guessing

pisesh is a single-file Node script (no dependencies, ~1,600 LoC) that gives you everything pi --resume doesn't.

Value at a glance

Getting started

Install the /sesh command in pi (recommended)

pi install npm:pisesh

This registers pisesh as a pi extension. Inside any pi session, type /sesh. The extension runs its bundled CLI, so a global npm installation is not required.

/sesh does not start a second pi process. The picker returns the selected session and options to the extension, which calls pi's official ctx.switchSession() API. Standalone pisesh keeps its shell behavior and starts pi --session. Custom cwd overrides require a pi version that supports cwdOverride on extension session switches; pisesh warns if pi ignores one.

Install the standalone CLI

npm install -g pisesh
pisesh

The standalone pisesh shell command requires this global npm installation. It is separate from pi install npm:pisesh.

From source (developers)

git clone https://github.com/Blue-B/pisesh.git
cd pisesh
npm link            # symlink ./bin/pisesh into your global PATH
pisesh --help

For local pi testing, run pi install . from the cloned repository so the extension and its bundled CLI stay together.

Keys

Title generation sends up to 16 KB of session text to the selected model provider and may incur provider charges. It excludes tool results and disables context files, skills, prompt templates, and tools.

CLI (non-TUI) usage

For scripts and automation:

pisesh --list                  # print starred session IDs (one per line)
pisesh --json                  # full favorites file as JSON
pisesh --star <partial-uuid>   # star a session from a script
pisesh --unstar <partial-uuid> # unstar
pisesh --clean-favorites       # remove favorites whose sessions are gone
pisesh --version               # print installed version
pisesh --help

Tech Stack

What it explicitly does not depend on

• No npm install for the bundled CLI runtime; it's genuinely zero-dependency
• No native binaries / GPU / ffmpeg / database
• No telemetry or analytics; title generation contacts only the provider for the model you select
• No daemon / background process

Storage

Favorites file shape:

{
  "ids": [
    "019e79b9-d2c1-741f-81ea-1dcad9a2d712",
    "019e6355-9957-7a30-b4ce-b9db5e3c9ac6"
  ],
  "updated": "2026-05-31T01:33:21.234Z"
}

It's a single global file (not per-project). Back it up by syncing one file.

CJK-aware rendering

Korean / Chinese / Japanese / fullwidth characters render 2 cells wide in terminals; pisesh measures display width (not JavaScript code-unit length) when truncating and padding. Korean prompts never wrap, columns stay aligned, and the layout looks identical whether the prompt is hello world or 안녕하세요 세상.

(Previously: Korean prompts overflowed to a second line and broke the table.)

Requirements

• Node.js ≥ 18 on PATH (the /sesh extension uses node to run its bundled CLI)
• A terminal with ANSI escape and alternate screen buffer support, which covers basically every modern emulator:
  • Windows: Windows Terminal, WezTerm, Alacritty ✅
  • macOS: iTerm2, Terminal.app, WezTerm, Alacritty, Kitty ✅
  • Linux: GNOME Terminal, Konsole, xterm, Alacritty, Kitty ✅
• pi on $PATH when using standalone pisesh

Support

If pisesh saves you context-switching time or just makes pi nicer to live in, supporting it directly accelerates development:

• Your support helps: bug fixes, new keybindings, more search modes, integration with other pi extensions.
• Transparency: I don't sell data; funds go to development time and a coffee or two.
• One-time sponsors are credited in README and release notes (opt-out available).
• Monthly sponsors ($3/mo via GitHub Sponsors) get best-effort priority triage for "Sponsor Request" issues.

Acknowledgments

• pi-coding-agent by @mariozechner, the agent and extension API that make /sesh possible.
• interactive-shell example extension, the pattern reference for the ui.custom + tui.stop TTY handoff.
• Inspiration for the favorites + tabs UX: droid CLI and tmux's sesh.
