Enum ToolKind 

#[non_exhaustive]
pub enum ToolKind {
    Read,
    Write,
    Edit,
    Search,
    Execute,
    Other,
}

A neutral, cross-harness classification of what a tool call does — so a consumer can route by behaviour (a read → a context pill, an edit → a file-op card) without re-encoding each harness’s native tool vocabulary (bob’s read_file, Claude’s Read, codex’s file_change). The raw name is kept alongside for display/phrasing; tool_kind is for behaviour. Named tool_kind (not kind) so it never collides with the #[serde(tag = "kind")] event discriminator on RunEvent.

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.

Read

Read or inspect a file’s contents.

Write

Create or overwrite a whole file.

Edit

Modify part of an existing file.

Search

Search or list files / the web.

Execute

Run a shell command or external process.

Other

Anything else (MCP calls, task spawns, completion signals, …).

Trait Implementations

impl Clone for ToolKind

fn clone(&self) -> ToolKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ToolKind

impl Debug for ToolKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ToolKind

impl PartialEq for ToolKind

fn eq(&self, other: &ToolKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ToolKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
