Crate replysieve 

replysieve judges user comments: approve, reject or needs_review, with a reason, at light, medium or heavy strictness.

Free pre-checks (length, stock phrases, duplicates, injection markers) run first with no network call. Comments that pass go to a decision model on OpenRouter, tried model by model in the order you give.

use replysieve::{Checker, Comment, Decision, Level, Options, Reason};

let checker = Checker::new(
    Options { level: Level::Medium, ..Options::default() },
    std::env::var("OPENROUTER_API_KEY").ok(),
);

// Stock praise is rejected by a free pre-check, with no model call.
let verdict = checker.check(&Comment::new("Great product, love it!!"), &[]).await?;
assert_eq!(verdict.verdict, Decision::Reject);
assert_eq!(verdict.reason, Reason::StockPhrase);
assert_eq!(verdict.model, None);

// Anything that passes the pre-checks goes to the model.
let comment = Comment {
    title: Some("Taskly, a todo app with offline sync".into()),
    ..Comment::new("Does offline sync merge edits made on two phones?")
};
match checker.check(&comment, &[]).await {
    Ok(v) => println!("{}", serde_json::to_string(&v).unwrap()),
    Err(e) => eprintln!("{e}"), // no OPENROUTER_API_KEY set
}
