Local configuration preflight

Check the boundary before sharing anything.

This page validates the shape of a public GitHub repository, pinned commit, and two file paths entirely in your browser. It does not fetch GitHub, upload files, or run the Action.

Accepted MVP shape

  • One public owner/repository
  • One immutable 40-character commit SHA, never a branch name
  • One .md or .mdx path
  • One .json, .yaml, or .yml path
  • No absolute path, URL, encoded character, ., or .. segment

Passing this preflight only means the identifiers fit the input grammar. It does not establish that the repository is public, the files exist, or the content will produce a determinate result.
