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

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

Reminds of factory factory factory! https://factoryfactoryfactory.net/

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

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

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.

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

How would you invoke the subagent? Can a HookResponse cause a subagent to be invoked, to perform analysis on the action taken and then inject that back into the main loop?

Or would the hook invoke another instance of claude code?

I just read through the hook docs and I’m a bit fuzzy on the bidirectionality of it.

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.

Sounds like video streaming services…

An agent's agent?

Sounds like a wip to me, "do it better or get punished"

Can the same concept be used for non coding tasks?
benzible 11/3/2025||
Cool concept, but I picture Quibbler as an off-brand Batman villain.
