Ctrl+P did nothing when the scope held exactly one model and the active
model was a different one. It showed "Only one model in scope" and kept
the current model, because `_cycleScopedModel` returned early for any
list with one entry. `_cycleAvailableModel` had the same early return,
so it also failed when the active model was no longer available and one
other model was.
A second bug had the same cause. When the active model was not in the
list, the code treated it as if it were at index 0, so cycling forward
skipped the first scoped model. With `--models A,B` and another model
active, Ctrl+P went to B.
This change adds a small `getNextCycleIndex` helper that both functions
now use:
- When the active model is not in the list, cycling forward selects the
first entry and cycling backward selects the last.
- It returns `undefined` (the "Only one model…" message) only when the
list is empty, or when its single entry is already the active model.
**Testing**
- Added a regression test to
`test/suite/agent-session-model-extension.test.ts`. It covers a
one-model scope, a repeated cycle once that model is active, and forward
and backward cycling into a two-model scope from outside it. The test
fails without the change ("expected undefined to be 'faux-2'") and
passes with it.
- `npm run check` passes.
- Manual check: `pi --model anthropic/claude-sonnet-4-5 --models
anthropic/claude-opus-4-5`, then Ctrl+P.
- Before: "Only one model in scope".
- After: "Switched to Claude Opus 4.5".
- With `--models anthropic/claude-opus-4-5,anthropic/claude-haiku-4-5`,
Ctrl+P now selects opus instead of haiku.

Pi
Pi is a minimal, extensible agent harness that you can make your own.
Adapt Pi to your workflows, not the other way around. Customize Pi with extensions, skills, prompt templates, and themes. Bundle them as Pi packages and share via npm or git.
Pi ships with powerful defaults but skips features like sub-agents and plan mode. Ask Pi to build what you want, or install a package that does it your way.
Use Pi interactively, automate it in print or JSON mode, control it over RPC, or build apps with the Pi TypeScript SDK. See OpenClaw for a real-world integration.
Getting started
Install the command-line interface:
curl -fsSL https://pi.dev/install.sh | sh
On Windows:
powershell -c "irm https://pi.dev/install.ps1 | iex"
The installer pins all dependencies and updates Pi with pi update. Alternatively, install directly with npm, which does not pin transitive dependencies:
npm install -g --ignore-scripts @earendil-works/pi-coding-agent
Pi requires Node.js 22.19 or newer. The macOS, Linux, and Windows installers can install it if needed. Pi does not require dependency lifecycle scripts for a normal npm installation.
On macOS and Linux, Nix users can install the latest release with nix profile add github:earendil-works/pi/stable. See the quickstart for updating and pinning releases.
Start Pi in the directory where you want it to work:
cd /path/to/project
pi
For a built-in AI provider, run /login inside Pi to connect a subscription or API key. Then give Pi a task.
See the documentation for full setup and usage instructions.
Share your OSS coding agent sessions
If you use Pi for open source work, please share your coding agent sessions.
Public OSS session data helps improve models, prompts, tools, and evaluations using real development workflows.
For the full explanation, see this post on X.
To publish sessions, use badlogic/pi-share-hf using a Hugging Face account and the Hugging Face CLI.
- Demo video on how to publish Pi sessions
- Published Pi development sessions:
badlogicgames/pi-monoon Hugging Face.
Development
Clone the repository, install its dependencies, and run Pi from source:
git clone https://github.com/earendil-works/pi
cd pi
npm install --ignore-scripts
./pi-test.sh
pi-test.sh can be called from any directory and preserves the caller's working directory.
Before submitting changes, run:
npm run check
./test.sh
