In other words, the Quibbler siphons wrackspurts away from your code.

The demo video in the GH page didn't work for me, but there is also one on Twitter/X: https://xcancel.com/fulcrumML/status/1984054489851310191

More explanation here that I found by Googling around. Though not sure it has more info than the Github page.

Is an anthropic api key really necessary? A major roadblock for taking a test drive. Already have a Claud Max subscription but an anthropic api key still need at least 5$/mon extra.

I really want Anthropic to let me make an API token that pulls from the same pool of usage that my Pro subscription does with the official clients. It would be cool to be able to run experiments with alternate clients and automation and stuff without having to go swipe the card at the ol' API token refilling station.

You could use the prompts in the code to create a Claude Code sub-agent[1], which would do the same thing without an API key

hey HN! happy to answer any questions

this kind of tool is especially useful in longer running tasks to enforce your intent without having to check in on your agent all the time

Can users stack Quibblers, so Quibbler 2 corrects Quibbler 1 if, say, it fabricates an issue in the code it's reviewing? If so, have you found an optimum number of Quibblers for the Quibbler stack? Also, might users form a Quibbler council such that multiple Quibblers review the same thing and form a consensus before proceeding?

I love the pixel-perfect precision with which this comment is straddling the Poe's Law line.

That aside I also love the concept of Quibbler Council and I'd get a kick out of seeing it in action.

MoQs - Mixture of Quibblers? Would be convenient to have them run on dedicated FGPAs. Then they can facilitate near real-time quibbing at the network level across all packets.

There's so many agents to handle my agents, I'm gonna need agents for my agent agents soon.
