agcli

agcli is a no-bloat Rust crate for building agent-native CLIs.

It is built around the design in design.md:

• JSON-only envelopes
• HATEOAS next_actions
• self-documenting root command tree
• context-safe output truncation
• typed NDJSON streaming with terminal result/error

Install

[dependencies]
agcli = "0.3.0"
serde_json = "1"

Quick start

use agcli::{AgentCli, Command, CommandOutput, NextAction};
use serde_json::json;

fn main() {
    let cli = AgentCli::new("ops", "Agent-native operations CLI")
        .version("0.3.0")
        .command(
            Command::new("status", "Show system health")
                .usage("ops status")
                .handler(|_req, _ctx| {
                    Ok(CommandOutput::new(json!({ "healthy": true })).next_action(
                        NextAction::new("ops status", "Re-check status"),
                    ))
                }),
        );

    let run = cli.run_env();
    println!("{}", run.to_json());
    std::process::exit(run.exit_code());
}

• command tree responses
• contextual next actions
• log truncation file pointers
