Error message

No prompt provided.

What it means

run_flow_agent_capture_streaming (public API in src/agents.rs) streams agent output while capturing the final response. Like run_flow_agent_capture it unconditionally calls find_gen() and bails with the install message when the gen tool/repo cannot be found, before any streaming starts.

Solutions

1. Install gen: cd <gen_repo_hint> && f install.
2. Export GEN_REPO pointing at the gen repo in the shell/profile that launches the program.
3. Pre-check gen availability (PATH/env) in the host application before invoking the streaming API.

Example fix

// before (cron env lacks GEN_REPO)
0 * * * * flow-stream-job
// after
+ 0 * * * * GEN_REPO=/home/user/src/gen flow-stream-job

if std::env::var("GEN_REPO").is_err() && which::which("gen").is_err() {
    return Err(anyhow!("gen unavailable; export GEN_REPO first"));
}

match agents::run_flow_agent_capture_streaming(prompt) {
    Err(e) if e.to_string().contains("gen not found") => {
        eprintln!("streaming needs gen; install it or set GEN_REPO");
    }
    Ok(text) => text,
}

When it happens

Trigger: Calling flow::agents::run_flow_agent_capture_streaming(prompt) when gen is not installed/locatable — error is raised immediately, prior to prompt validation or streaming.

Common situations: Same as run_flow_agent_capture: missing gen checkout on dev machine or CI; GEN_REPO not exported in the process environment (e.g. launched from a GUI app with a minimal environment).
