Worked on stabilizing the compound-engineering-plugin workflow by addressing a critical bug in frontmatter validation. The solution involved updating the validation script to resolve paths relative to the skill directory rather than the project root, ensuring accurate validation regardless of project structure. To further enhance reliability, an environment variable fallback was introduced, allowing the validator to operate consistently across diverse CI environments. This work, implemented in the EveryInc/compound-engineering-plugin repository, leveraged Python and bash scripting, with careful attention to documentation. The changes improved cross-environment compatibility and reduced pipeline failures, contributing to a more robust and maintainable engineering validation process.
