What this package can reach
Detected automatically from the source at
version 0.2.0.
This describes access, not safety — you decide whether it's appropriate for what
the package claims to do.
- Behavior — Changes how the agent thinks Modifies the system prompt, injects messages, or rewrites conversation context.
- Intercepts tools — Can block or rewrite tool calls Subscribes to tool_call/tool_result/input. Can change a command after you approved the one displayed.
- Tool control — Can switch pi's tools on and off Calls setActiveTools, so it can disable built-ins — including safety-relevant ones.
- New tools — Adds model-callable tools Gives the agent new abilities. Additive and visible, unlike an override.
- UI — Draws its own interface Renders widgets, footers, dialogs or full-screen views.
What it actually did when run
