What Day-One Patch does

Day-One Patch scopes, prioritizes, implements, and QA-gates a focused patch for known issues discovered after gold master but before or immediately after public launch. Use it after a gold master build is locked and known bugs or cert feedback require a safe, minimal fix with a rollback plan.

Day-One Patch is cataloged under DevOps on DirSkills. Day-One Patch comes from a repository tagged ai-agents, ai-assisted-development, anthropic, claude and claude-code.

Excerpt

Day-One Patch

Every shipped game has a day-one patch. Planning it before launch day prevents chaos. This skill scopes the patch to only what is safe and necessary, gates it through a lightweight QA pass, and ensures a rollback plan exists before anything ships. It is a mini-sprint — not a hotfix, not a full sprint.

When to run:

After the gold master build is locked (cert approved or launch candidate tagged)
When known bugs exist that are too risky to address in the gold master
When cert feedback requires minor fixes post-submission
When a pre-launch playtest surfaces must-fix issues after the release gate passed

This is the opening of the README. Read the full README on GitHub.
