Enum Matcher 

#[non_exhaustive]
pub enum Matcher {
    All,
    Bash,
    Exact(String),
    AnyOf(Vec<String>),
    Regex(String),
}

Which tool calls a hook should match.

Each integration translates this to its harness’s native syntax. For example, Claude Code accepts a regex when the matcher contains characters outside [A-Za-z0-9_|], so Matcher::Regex passes through verbatim.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

All

Match any tool call.

Bash

Match the harness’s “Bash”/“Shell”/“shell” tool (whatever it calls command execution). Each integration maps this to the right literal.

Exact(String)

Match exactly this tool name (e.g., "Edit", "Read").

AnyOf(Vec<String>)

Match any of these tool names.

Regex(String)

Match using the harness’s regex syntax (passed through unchanged).
