Session workers now host a durable Harness over a per-session sqlite storage. The server keeps each session in <sessionDir>/<id>/ with meta.json and session.sqlite and never opens the storage itself. Workers hold retirement while the Harness task graph has live tasks and resume interrupted work on open. Transcript serves the root conversation's durable view directly, Models follows the conversation's agent document, and AgentController maps prompt, steer, follow-up, queue cancellation, abort, and compaction onto the root conversation, plus waitForPrompt. navigate, nextRun, and resume are dropped (see experimental/services/README.md TODO). The durable TUI and the worker share harness-setup.ts. pi-server exports its own SessionMetadata and no longer depends on pi-agent-core. Chord accepts readonly JSON types in service contracts without walking them, which recursive JSON types like pi-ai's made too deep. |

Pi
Pi is a minimal, extensible AI agent for the terminal. Adapt Pi to your workflow, not the other way around.
Ask Pi to create the prompt templates, skills, extensions, and themes you need, or install a Pi package. Use Pi directly, automate it in print, JSON, or RPC mode, or build applications with the TypeScript SDK.
Getting started
Install the command-line interface with npm:
npm install -g --ignore-scripts @earendil-works/pi-coding-agent
This requires Node.js 22.19 or newer. Pi does not require dependency lifecycle scripts for a normal npm installation.
On macOS or Linux, you can instead use the installer:
curl -fsSL https://pi.dev/install.sh | sh
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.
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
