How to build a plugin tool that loads into every rpi session with Pi Rust

What you need first

• Rust 1.78 or later, for installing from crates.io
• An ANTHROPIC_API_KEY or OPENAI_API_KEY, or a ~/.rpi/agent/models.json file, for live model calls
• Git, to clone the repository for the offline examples

Steps

1. Run git clone https://github.com/bigfish1913/pi-rust.git
2. Open examples/plugin-stub and read how it uses rpi-plugin-sdk
3. Run cargo build -p plugin-stub from the repository root to build the cdylib (inferred, check the README)
4. Place the built library where the rpi plugin loader expects it, following docs/agent/project-structure.md

Prompt for your agent

In the bigfish1913/pi-rust repository, copy examples/plugin-stub into <new-plugin-folder>, implement one tool in it, and build it as a cdylib. Expected output: a compiled shared library that rpi can load. Verify that `rpi --version` still runs after the plugin is placed in the loader path.

Caveat. The README does not give the plugin install path or build command, so confirm them in examples/plugin-stub and docs/agent/project-structure.md before copying files.
