Hacker News Mention Monitor with Codex

A monitor loses your trust by crying wolf: nine hits, seven of them an unrelated company with your name. This template drops those before anything is counted, and the rest of the run is search calls, item fetches and one structured message. Codex is quick through that kind of concrete pipeline, which keeps twenty-four sweeps a day affordable.

Live demo

Watch it work before it's live

Run a staged conversation — no account needed. The agent handles it for real while a simulated world answers its tool calls; nothing touches real accounts, and nothing is actually sent.

Hourly sweep, Tuesday 14:00

Hourly scheduleevery hour, on the hour

The 14:00 tick fires. A Show HN posted 40 minutes ago is at 168 points and 74 comments, sitting fourth on the front page. The top comment, from user tkachenko, asks how self hosting compares with the incumbent, two people report that the docs link returns a 404, and a competitor's founder has replied twice in the thread.

What you'll need

Set up in minutes

Using this template drops you into a guided setup. It asks exactly this, nothing else:

  1. Connect Hacker News

    One sign-in. The agent acts through your account, scoped to what this template uses.

  2. Connect Slack

    One sign-in. The agent acts through your account, scoped to what this template uses.

  3. Watch terms

    Every term worth watching, in your own words: your product and company names, your domain, your founders' Hacker News handles, and the competitors you want to hear about. The agent searches exactly these, so include the spellings and misspellings people actually type.

  4. Ping policy

    What earns an immediate Slack ping versus a line in tomorrow's roundup, for example a front page story or a complaint thread pings while a passing mention waits, plus the channel and the hours you are happy to be interrupted in.

  5. Runs on Codex

    Preselected for this page — connect your Codex account during setup, or switch to NoClick's built-in models with one click.

  6. Watch it handle a test run

    A staged conversation against a simulated world — then it’s live.

A considered pairing

Why Codex for this agent

Cheap on empty hours

Most sweeps end with nothing sent, so speed on the boring ticks is what the monthly cost actually tracks.

Search, fetch, format

Two search modes, an item fetch, a comment read and a four-section message is a bounded sequence with an obvious end.

Good to know

Before you fork

Will it quote commenters accurately?

The instructions require verbatim quotes with usernames attached and forbid paraphrasing anyone into an opinion they did not state. Verify rather than assume: Front Page Show HN gives you three real comments to check the output against. Misquoting a stranger in your own Slack is recoverable, but it is not the first impression you want.
