Worked on the allthingslinux/tux repository with a focus on configuration reliability and environment management. Addressed a critical issue by correcting the Sentry environment variable in the .env.example file, changing SENTRY_URL to SENTRY_DSN to ensure proper error tracking across development, staging, and production environments. This update aligned configuration files with runtime expectations, reducing the risk of misconfigured Sentry initialization. Employed configuration skills and adhered to conventional commit standards to improve traceability and changelog accuracy. The work centered on environment variable management and configuration hygiene, with no new features added during the period but a key bug fix delivered.
