nopus - deterministically detect and automatically rewrite complex responses

TL;DR: I made nopus , a tool that deterministically detects unnecessarily complex prose in coding-agent responses and automatically asks the same agent for one clearer rewrite.

With recent LLMs (you can probably guess from the name which one caused me to write this plugin), I've had more and more trouble understanding the prose the agents are responding with - long "load-bearing" paragraphs, abstract language, overloaded phrases and all that fun stuff.

My logic is the cognitive capacity should be spent on the underlying problem not trying to decipher the message.

I found a few solutions that pass the response through a smaller model, but I wasn't a fan of the tradeoffs:

- The smaller model may receive only the isolated response which can cause it to simplify or reinterpret the wrong thing

The other option is to have a user-invocable skill you invoke when a response is hard to understand, that works but again, the onus is on you to first read the response and determine whether you even understand it, I also added a skill for that but it's a fallback not the main approach.

Measure those signals, identify the biggest offenders, and give that evidence back to the original agent.

nopus uses lifecycle hooks, checks the prose after the agent finishes responding. If enough signals cross the selected threshold, it asks for one clearer rewrite.

The rewrite happens in the same session, so the original agent keeps the full conversation context.

I ran it against 5,337 completed agent responses. At the default medium sensitivity, it triggered on around 10% of them, which I've evaluated myself and tuned so it doesn't trigger unnecessarily.

The repo has a few more details but I'd love for you to check it out.

Currently available for Pi, Codex and Claude Code (or just slop fork your own lol)
