@ernilambar Thanks for fixing all these typos everywhere. Instead of doing all of that manually, it would be easiest to just set up a GitHub Action to do this. See https://github.com/WordPress/plugin-check/blob/571a65a3f993fcc5bb7faf04fbb5d16c696cd599/.github/workflows/spell-check.yml for an example.

This could be added to https://github.com/wp-cli/.github/tree/7f6b72e950f06caabb5e8875e1f85f4a561cb63b/.github/workflows and all WP-CLI repositories would automatically benefit from automated spell check.

Would you be interested in submitting a PR for that?

[ernilambar]

@swissspidy Sure. I will try that approach.

[ernilambar]

@swissspidy Should this Spell Check action be kept inside workflows/reusable-code-quality.yml file?

[swissspidy]

Sure that works
