This repository provides a GitHub Action that wraps the lychee link checker to validate links in Markdown, HTML, and text files. The action downloads and installs a specified version of lychee, runs it with configurable arguments, and processes the output to set exit codes and generate reports. The core action is well-designed with robust version handling and error processing, but the associated workflow files show signs of technical drift due to outdated action versions (e.g., actions/checkout@v7 which doesn't exist). The action is actively maintained with recent commits and automated version update workflows.
