Struct Agent 

pub struct Agent {
    pub name: &'static str,
    pub command: &'static str,
    pub args: &'static [&'static str],
    pub requires: &'static [&'static str],
    pub install_hint: &'static str,
    pub model: &'static str,
}

A single registered ACP agent harness.

Maps a public name (used by the LLM in the tool call) to the command that launches the harness in ACP mode. Unlike the previous one-shot integration there are no per-agent prompt flags: the prompt travels as the ACP session/prompt payload, so adding an agent is purely a table entry.

requires lists the binaries that must be present in PATH for the agent to be considered installed — the launch command itself plus whatever engine backs it. The official claude/codex entries spawn the ACP adapter via npx, so they additionally require npx.

Fields

name: &'static str

Public name used by the LLM in the subagent_call tool.

command: &'static str

Executable that speaks ACP over stdio.

args: &'static [&'static str]

Static arguments that put the executable into ACP server mode.

requires: &'static [&'static str]

Binaries that must be in PATH for this agent to be offered.

install_hint: &'static str

Installation guidance surfaced when the spawn fails.

model: &'static str

Preferred session model, selected through the standard ACP session/set_config_option request when the harness advertises a model config option in session/new.

Harness defaults are frequently a paid-tier model, while the same CLI’s own run command uses a working free/default model — the harness’s ACP default and its CLI default need not agree. An empty value leaves the harness default untouched.

Implementations

impl Agent

pub fn invocation(&self) -> String

Human-readable ACP launch command (e.g. gemini --experimental-acp) used in the tool description and docs. The prompt travels as the ACP session/prompt payload, so only the launch command is shown.

Trait Implementations

impl Clone for Agent

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Agent

impl Debug for Agent

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

Formats the value using the given formatter.
