What this package can reach
Detected automatically from the source at
version 0.1.6.
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.
- Commands — Runs shell commands Spawns processes on your machine.
- Credentials — Handles your API keys Reads or passes provider credentials. Highest-trust capability there is.
- Files — Reads files outside your project Touches paths beyond the working directory, such as your home folder.
- 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.
- Network — Talks to the internet Makes outbound network requests. Check the destinations are ones you expect.
- Subagents — Spawns agents or sessions Runs additional agents. Ask whether it caps iterations and spend.
- 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
observedLoaded in a sandbox with no network, a read-only filesystem and a recording stand-in for pi's API. This is what it called — not what the source suggests it might.
Replaces pi's built-in tools: read, grep, bash, edit, write.
Every use of those tools goes through this
package instead of pi.
