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: β favorites, instant search, and a[NOW]
badge for the session you're attached to.
Real capture: β starred session at the top, the rest available behind the Today, Here, and All tabs.

resumes.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 β
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 β
marker in the list:** p re-points the working directory** through an arrow-key directory browser. This is the cwd pi actually
cd
s 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.
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.
| Need | What you get |
|---|---|
| Mark important sessions | β Star/unstar with one keystroke; favorites persist to one global JSON |
| Give a thread a real name | e sets one manually; g generates one with a model you choose |
| See only the current project's sessions | Here tab filters to sessions whose cwd matches where you launched pisesh |
| Fix where a session resumes | p opens an arrow-key directory browser; sets the cwd pi cd s into |
| Find a session by what you said | / searches id + project + first user prompt + custom title |
| Know which session you're attached to | [NOW] badge on the live session (passed from pi via env var) |
| Keep your terminal clean | Alt-screen buffer, so quitting puts your terminal back the way it was (like vim) |
| Read Korean / Chinese / Japanese prompts | Display-width-aware truncation; columns never blow up on CJK |
| Open from anywhere | Run as standalone pisesh shell command, or /sesh inside pi |
| Zero install pain | No build step, no native deps, runs on Node 18+ everywhere |
| Trust it with your history | favorites and overrides stay in sidecar JSON; session history changes only for orphan-call repair |
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.
npm install -g pisesh
pisesh
The standalone pisesh
shell command requires this global npm installation. It is separate from pi install npm:pisesh
.
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.

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.
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

| Area | Details |
|---|---|
| Runtime | Node.js β₯ 18 (uses only built-in modules: fs , path , os , child_process , readline ) |
| TUI rendering | Raw ANSI escape sequences (no blessed / ink / chalk dependency) |
| Alt screen buffer | \x1b[?1049h / \x1b[?1049l , the same primitive vim , less , htop , and droid CLI use |
| Input | Node's readline.emitKeypressEvents in raw mode |
| Width calculation | UAX #11 East Asian Width ranges, compressed to ~10 inline range checks |
| Pi extension | TypeScript factory using ui.custom , tui.stop , and ctx.switchSession() |
| Storage | Two JSON files under $PI_AGENT_DIR : favorites.json and pisesh-meta.json |
| Session discovery | Direct filesystem scan of ~/.pi/agent/sessions/<projectSlug>/*.jsonl ; first 96 KB parsed |
| Process model | /sesh runs pisesh as a selector and switches the current runtime; standalone starts pi |
| Resume settings | Enter uses current defaults; o preserves the model and thinking recorded in the session |
| Custom paths | Honors PI_AGENT_DIR and PI_SESSION_DIR , including a flat custom session directory |
| Title generation | Ephemeral pi --print --no-session call using the model and effort selected in pisesh |
- 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
| What | Where |
|---|---|
| Favorites | $PI_AGENT_DIR/favorites.json (defaults to ~/.pi/agent/favorites.json ) |
| Overrides | $PI_AGENT_DIR/pisesh-meta.json (per-session title / cwd plus the saved title model + effort preset) |
| Sessions | $PI_SESSION_DIR , or $PI_AGENT_DIR/sessions by default (repaired only when an orphaned tool call would break resume) |
Favorites file shape:

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

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.

The pi extension uses the @earendil-works/pi-coding-agent
API; check pi's own license for that side. The CLI binary is pure Node and has no other licenses to worry about.
