YouTube Comments Agent with Codex
Cost here follows how many comments have to be read, not how many subscribers you have, so a channel taking two thousand comments a night is a real and predictable expense. Codex is quick through the reading and the grouping, which is most of the run. The lever that actually moves the bill is scoping the channel rules to recent uploads rather than the whole back catalogue.
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.
Comments digest, Tuesday 14 April
312,000 subscribers. Overnight there are 214 new comments across six videos, 90 of them on Sunday's dovetail jig tutorial, which has passed 180,000 views. Eleven people ask which router bit was used and the video never says, four ask whether the jig fits an imperial base, and one account named for a Spanish tool brand asks who handles paid collaborations.

Channel rules
What your channel wants surfaced and how you sound when you answer: which questions deserve a reply, who handles sponsorship and press, what you treat as spam, and any subject you never discuss in the comments. Draft replies copy the tone you describe here.

Why Codex for this agent
One morning pass, sized by volume
A single run reads what arrived overnight. The comment count is the variable, and it is one you can see coming from the channel's own numbers.
Split the pass on busy channels
Heavy channels often run it twice a day so neither pass has to swallow everything. Two smaller reads land better and cost roughly the same.
Before you fork
Does an old upload waking up change what we pay?
It can, and that is usually the surprise: a two year old tutorial being recommended again brings a wave of comments about advice that has since moved on. The agent notices the shift and names the video, which is the useful part. Expect spend to track your recommendation traffic rather than your upload schedule.
