Parses a structured GitHub issue body into validated submission fields, normalizes repository URLs, enforces terminal punctuation, inserts entries into both Chinese and English READMEs in the correct category, and sorts entries by repository name. It rejects duplicate URLs and validates required confirmations. The pattern of converting a human-filled form into consistent multi-file content changes is reusable for any curated list or documentation automation project.

A self-contained Markdown link checker that extracts links while ignoring fenced code blocks, checks relative paths against the workspace, and validates remote links with HEAD requests followed by GET fallback. It is parameterized with injectable fetch implementations for testability and uses a simple ignore list for known-excluded targets. This can be extracted into any project needing lightweight Markdown link validation without external dependencies.

Validates that the Chinese and English READMEs list identical URLs in each category, enforces repository-name sorting within sections, detects duplicate URLs, and asserts that contribution guides, issue templates, and READMEs all reference the required submission process. It converts implied editorial rules into executable checks, demonstrating a reusable approach for maintaining structured curated lists across multiple language versions.

A novel test harness that extracts the inline JavaScript from a GitHub Actions workflow YAML file and executes it against meticulously mocked GitHub REST API objects. It verifies nuanced behaviors: old failed runs do not override newer success, third-party green checks cannot replace required core checks, workflow-changing PRs require manual merge, and permission failures surface correctly. This pattern of testing embedded CI logic with mocks is reusable and demonstrates non-obvious engineering craftsmanship.
