Chrome Ext Service Worker

Category: General  ·  Sub-category: general-misc  ·  Last updated:
This skill should be used when working with Chrome extension service workers or background scripts. Trigger when: "service worker lifecycle", "background script", "extension service worker", "chrome.alarms", "offscreen document", "service worker restart", "top-level listener", "service worker idle", "event listener registration", "chrome.offscreen", "service worker termination", "state rehydration", "persistent background", "MV3 background", "service worker wake-up", "keepalive", "setTimeout in service worker".

From the source SKILL.md

MV3 replaced persistent background pages with ephemeral, event-driven service workers. They wake to process events and terminate after ~30 seconds of inactivity. All in-memory state is lost on termination. Code must be structured around this fundamental constraint.

What this skill does

Chrome Ext Service Worker is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/chrome-ext-service-worker/ and loads when your prompt matches the skill's trigger.
