Description

I keep seeing "highly" used as a general intensifier like "very" in all kinds of places it didn't used to be used. I made a linter for the specific case of "highly kept secret" some months ago. This linter is more general.

It includes a check against words that do commonly collocate with "highly". Any others will be flagged with "very" requested as a replacement. A second list has specific replacements for specific words.

I went back and forth with an AI on which words to include or not, starting with all instances of "highly" in my corpus of READMEs from GitHub.

How Has This Been Tested?

AI Disclosure

• I am a human and didn't use any AI.
• I used LLM features of my editor, but not an agent.
• I consulted one or more coding AIs, but didn't use an agent.
• I used an AI agent interactively.
• I am an agent or I got an agent to do the work autonomously.

I mostly used AI for going over the word lists but I also got it to make my linter code more Rusty once my hand-coded version worked as I wanted it to.

If Your PR Implements or Enhances a Linter

• I made up the sentences in the unit tests.
• The sentences in the unit tests were generated by an AI.
• I'm using examples from the bug report / feature request.
• I collected real-world sentences for the unit tests.

Checklist

• I have performed a self-review of my own code
• I have added tests to cover my changes
• I have considered splitting this into smaller pull requests.
