Plugin Development

The Rust CLI uses built-in assertion plugins implemented in src/plugins/.

Important

• Runtime plugin files are not loaded from disk
• Commands like --create-plugin/--list-plugins are not available
• Plugin behavior is native and loaded automatically at startup

Built-in Plugin Functions

Use plugin functions in ASSERTS, for example:

--- ASSERTS ---
@header("x-request-id") != null
@uuid(.user.id, "v4")
@email(.user.email)
@url(.profile.website, "https")

Contributing New Plugins

To add a new built-in plugin:

1. Implement a plugin module in src/plugins/
2. Register it in src/plugins/mod.rs
3. Add tests for parser/assertion behavior
4. Document usage in this section
