Immanuel Pelzer enhanced the documentation for Slack integration in the checkly/docs.checklyhq.com repository by adding a warning about message limits for free Slack workspaces. Using Markdown and focusing on clear, user-oriented documentation, Immanuel addressed a common integration issue where alerts could be undelivered due to Slack’s free-tier restrictions. The update aimed to improve user awareness and onboarding by explicitly outlining potential limitations, thereby supporting more reliable alerting workflows. While no bugs were fixed during this period, the work demonstrated attention to detail and a commitment to documentation quality, ensuring that operational risks related to Slack integration were clearly communicated to users.
