pi-profiles

Configuration profile manager for pi. Switch between independent sets of settings, extensions, skills, themes, and auth with a single command.

Inspired by chemacs (Emacs profile switcher) and Neovim's NVIM_APPNAME.

How it works

Pi resolves its configuration directory via PI_CODING_AGENT_DIR. ppi creates and manages profile directories under ~/.pi/profiles/<name>/, then launches pi with the env var pointed at the chosen profile. Pi doesn't know it's being wrapped - the TUI renders directly through inherited stdio.

Install

npm install -g pi-profiles

Requires pi and Node.js (which you already have if you have pi).

Usage

# Create a profile
ppi create work
ppi create personal --own-auth    # independent API key

# Create from your current pi config
ppi create work --from-base

# Copy an existing profile
ppi create experiments --from work

# List profiles
ppi list

# Set a default
ppi set-default work

# Launch pi with a profile
ppi use work
ppi                               # launches the default profile
ppi use work -- -p "fix the bug"  # pass args to pi after --

# Delete a profile
ppi delete experiments            # interactive confirmation
ppi delete experiments --force    # skip confirmation

What a profile looks like

Each profile is a complete pi agentDir:

~/.pi/profiles/work/
├── settings.json
├── auth.json → ~/.pi/agent/auth.json  (symlink by default)
├── models.json → ~/.pi/agent/models.json
├── extensions/
├── skills/
├── tools/
├── prompts/
└── sessions/

Auth and models are symlinked from the stock pi config by default, so one pi login works everywhere. Pass --own-auth or --own-models to create for independent credentials.

Goals

• Full isolation. Each profile is its own agentDir - settings, extensions, skills, themes, auth, sessions, prompts. Switching profiles means switching everything.

• Zero pi modifications. Works entirely through the documented PI_CODING_AGENT_DIR env var and convention. No patches, no forks.

• Zero runtime dependencies. Pure Node.js filesystem operations. Hand-rolled arg parser. Nothing to install beyond this package.

• Library + CLI. ProfileManager class can be used programmatically (e.g., by a future orchestrator calling createAgentSession({ agentDir })). The CLI is a thin wrapper.

• Composable. Profile paths are predictable (~/.pi/profiles/<name>/), so they work with external tools:

  docker run -v ~/.pi/profiles/work:/root/.pi/agent pi-image
  

Non-goals

• Process-level sandboxing. Profiles manage which config to use, not where code runs. Docker, VMs, and bubblewrap are orthogonal infrastructure concerns. Pi's built-in sandbox extension handles tool-level restrictions within a profile.

• Agent orchestration. Spawning multiple concurrent agents with different profiles is a motivating future use case, but the orchestrator itself is a separate project.

• Runtime settings patching. No mid-session model/tool switching. Pi's built-in /model command handles that.

• Registry file. Profiles live at ~/.pi/profiles/<name>/ by convention. No mapping file to maintain. The filesystem is the registry.

Programmatic usage

import { ProfileManager } from "pi-profiles";

const pm = new ProfileManager();
const profile = pm.resolve("work");
console.log(profile.path); // ~/.pi/profiles/work

// Use with pi's SDK
import { createAgentSession } from "@mariozechner/pi-coding-agent";
const { session } = await createAgentSession({ agentDir: profile.path });
