Enum ToolKind 

#[non_exhaustive]
pub enum ToolKind {
    Read,
    Write,
    Edit,
    Delete,
    Move,
    Search,
    Execute,
    Fetch,
    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.

The values mirror ACP’s tool-call kind (read/edit/delete/move/search/execute/fetch/other), so a RunEvent::ToolStart maps onto an ACP tool_call without a translation table. The one divergence: our Write (create/overwrite a whole file) has no ACP counterpart — ACP folds whole-file writes into edit — so an ACP bridge maps Write → edit.

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. (ACP read.)

Write

Create or overwrite a whole file. (No ACP kind — bridges to edit.)

Edit

Modify part of an existing file. (ACP edit.)

Delete

Delete a file. (ACP delete.)

Move

Move or rename a file. (ACP move.)

Search

Search or list files / the web. (ACP search.)

Execute

Run a shell command or external process. (ACP execute.)

Fetch

Fetch a URL / remote resource. (ACP fetch.)

Other

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