X (Twitter) Mention Monitor with Codex

An hourly sweep across two or three handles is a fixed twenty-four runs a day whether X is talking about you or not. Codex is quick on bounded work, which keeps the empty hours genuinely cheap, and for almost every brand the empty hours are most of them.

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.

so the free tier is gone and nobody thought to mention it, cool

Quote tweets our pricing update from this morning. 1,340 reposts, 4,800 likes and 210 replies in three hours, from an account with 48,000 followers that has recommended us twice before. The replies are split: several point out the grandfather clause in our own post, several say they already cancelled. Our original post is still live and has not been updated.

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 X

    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. Brand handles

    Every handle worth watching, starting with your brand account and any founder or product accounts people tag instead. Add handles you have renamed away from, because people keep using those for years.

  4. Ping policy

    What lifts a mention above the noise: follower counts, tone, whether somebody asked a direct question, and which Slack channel the ones that qualify should land 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

A fixed daily count

The schedule sets the number of runs, not your popularity. Knowing that floor before you start is half of the budgeting done.

Fetches are the bulk

Mentions, quote tweets over recent posts, a thread walk and an author lookup. Reading endpoints and reconciling what comes back is routine for this harness.

Good to know

Before you fork

Will an hourly sweep exhaust our X API quota?

That is the real constraint here rather than the harness. The read endpoints are metered per app, and each sweep spends a call per handle for mentions, a quote lookup per recent post, and a thread walk for anything it judges, so the monthly read budget scales with how many handles you watch and how active they are. Check the read cap on your X API tier against that arithmetic before trusting an hourly cadence, because the failure mode is quiet: mentions stop arriving rather than anything erroring.
