Fixes #9221.
An extension tool can lose its context when an RPC command or SDK caller
reloads the session during tool execution: the tool awaits work, reload
invalidates its runner, then `ctx.getSystemPrompt()` throws a
stale-context error. The failed tool result is stored in session
history.
Reject reload when `isStreaming` or `isCompacting` is already set,
before shutdown or runner invalidation. This gives RPC and direct
callers the same entry checks as the TUI. The production change remains
seven lines.
#9548 removed the wrapper access behind the original reproduction. The
regression exercises the tool's own context access after an await,
through both an RPC-style extension command and direct
`AgentSession.reload()`. Rejection preserves the successful result in
session history and the next provider request. Compaction, tree
navigation, and idle reload are also covered.
Scope: this guards operations already marked running or compacting. It
does not serialize reload with prompt preflight or prevent a new prompt
from starting during an ongoing reload.
Related: #5735 proposes a broader deferred-reload API. This patch only
adds the existing TUI entry checks to the core reload method.

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
