Fixes #11592. ## Problem WSL starts Windows programs in the current directory, translated to `\\wsl.localhost\<distro>\<cwd>`. When that path exceeds MAX_PATH, every Windows program fails to start with `Invalid argument`. pi inherits its cwd when spawning `powershell.exe`, so in a deep directory: - clipboard image paste returns `null` (the PowerShell backend fails, stderr is discarded) - copy via `powershell.exe` (WSL without WSLg) fails - opening the browser for sign-in fails (`xdg-open` on WSL runs `explorer.exe`) Reproduced on WSL (FedoraLinux-44): `powershell.exe` and `cmd.exe` work from a 225-char cwd and fail from 230. With an image on the Windows clipboard, `readClipboardImage()` returns the PNG from `/tmp` and `null` from a 245-char cwd; with this change it returns the PNG from both. `LongPathsEnabled=1` does not help. ## Changes - `runClipboardCommand` and `openBrowser` run from `/` on POSIX. These tools never use the cwd (temp files are passed by absolute path), and `/` is always the shortest UNC path. `tmpdir()` was not used because `$TMPDIR` can itself be deep. - The external editor keeps pi's cwd on purpose, so project-relative paths and integrated terminals keep working. A Windows editor such as `code` can still fail from a deep WSL directory, as with git's `core.editor`. A comment documents this. - External editor failures were silent: the UI redrew over the error immediately. pi now shows `Failed to launch external editor: <cmd>`, `External editor exited with code N; prompt unchanged`, or the signal name. This shows in the status line for the main editor and inline in the extension editor dialog. ## Testing - New tests: clipboard commands run from `/` (POSIX); an editor that cannot be launched is reported (POSIX); the existing failure test checks the message. - Verified on WSL by running the real modules: clipboard image paste from a deep cwd, and editor success, exit code 1, launch failure, and SIGTERM. - On Windows, the 3 existing `external-editor.test.ts` tests already fail on `main`: the editor command is split on spaces, so `C:\Program Files\nodejs\node.exe` breaks. Not addressed here. This PR is AI-generated. |

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.

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
