What's inside

launch-post-writer

README in → X post, 5-post thread, LinkedIn post, Show HN title and first comment, and a subreddit-style post. Uses only facts from your files.

landing-page-critique

URL in → a 7-point scorecard that quotes your page, the top 3 fixes with replacement copy, 3 new hero blocks, and one A/B test.

changelog-to-posts

Release notes or git log in → X post, thread, LinkedIn, email blurb, in-app "What's new", plus the 10-second demo to record.

Tested on real inputs

Each skill ships with its unedited test output. launch-post-writer and changelog-to-posts were run on the open-source hyperfine README and changelog. landing-page-critique was run on this site. (It scored my homepage 4 out of 14, which is why this page exists.)
