What eol-message does

This skill creates end-of-life notices calibrated to the scope of the retirement. Minor interface adjustments receive a brief heads-up of one to three paragraphs. Commercial offerings or core services receive a multi-stage communication plan with lifecycle milestones, spanning the period from halting new sales to final decommission. It articulates why the retirement happens from the customer perspective rather than corporate convenience.

The framework handles three distinct outcomes: directing users to an internal replacement, guiding migration to another tier, or sunsetting without a successor. For total shutdowns, the prompt insists on detailing data export steps and openly pointing toward third-party tools. Without a clear reason for the shutdown and explicit next steps for accounts, the skill stops to prompt for them, because omitting those details damages credibility.

What it helps with

  • draft clear sunset notices without triggering support ticket spikes
  • match announcement length to the real blast radius of the deprecated feature
  • communicate a complete product shutdown when no in-house alternative exists
  • break retirement timelines into plain-English operational milestones

Example prompts for the agent

  • Draft an EOL announcement for retiring our legacy analytics module on Dec 31, moving 400 teams to the new dashboard.
  • We are turning off an unused settings toggle in three weeks with no replacement. Write a brief notice for the changelog.
