Struct EffectDecl 

pub struct EffectDecl {
    pub type_name: &'static str,
    pub description: &'static str,
    pub constructors: &'static [&'static str],
    pub type_defs: &'static [&'static str],
    pub helpers: &'static [&'static str],
}

Static metadata describing a Haskell effect type.

Each effect handler that wants to participate in the MCP templating system implements DescribeEffect to provide its Haskell-side type declaration.

Fields

type_name: &'static str

Haskell GADT type name, e.g. "Console".

description: &'static str

Human-readable description of what this effect does.

constructors: &'static [&'static str]

Haskell GADT constructor declarations (one per line inside data T a where).

type_defs: &'static [&'static str]

Extra Haskell type/function definitions emitted before the GADT. Use for supporting types (e.g. data Lang = ...) and helper functions.

helpers: &'static [&'static str]

Thin curried helper definitions emitted after the type M alias. Each string is one or more lines of Haskell (signature + definition).
