Why CLUX exists
I spent six years at Canonical auditing command-line tools. The audit that started CLUX was for a team planning the next version of theirs. Once I saw the whole CLI, there was a pattern in the problems: commands that made no sense today were engineering decisions from six years earlier, the people who made them had moved on, and bug reports from that time were still open. The users who filed them had left too, for tools that were less painful. I had watched the same story play out across other CLIs for years. CLUX exists so a team can see that picture in an afternoon instead of discovering it six years too late.
CLUX grades the user experience of a command-line tool, for a person at the terminal and for an AI agent. You paste a command's help or output; CLUX checks it against a written rubric and returns a score, the evidence, and what to fix first. How scoring works

What we believe
Agents are the new users.
A CLI that confuses a person wastes minutes; one that confuses an agent wastes money, silently. Same fixes, higher stakes.
Consistency beats cleverness.
Most of what trips agents is one flag with eight meanings, not a bug.
Evidence or nothing.
A grade without a quote is an opinion; a quote without a grade is a log.
Who's behind it
@amylily spent six years at Canonical as a UX Manager, leading design for its cloud infrastructure products. She prototyped the CLIs in JavaScript to test them with users, and the research that came back led her to join forces with engineers to create a CLI style guide at Canonical. That guide, and six years of audits against it, became the rubric behind CLUX.
CLUX is made by Odd Parity Ltd in London. It's one person and a lot of terminals. Email help@clux.io; a human replies.

How the model is used
Each live evaluation sends your transcript to an AI model. Known secrets are replaced with labels first. The model provider doesn't train on it. The report is an opinion, and it can be wrong: check the evidence. Privacy Policy
