Chrome Ext Messaging

Category: General · Sub-category: general-misc · Last updated: 2026-05-21

This skill should be used when implementing messaging between Chrome extension components or when the user asks about inter-process communication in extensions. Trigger when: "extension messaging", "chrome.runtime.sendMessage", "chrome.tabs.sendMessage", "content script messaging", "port.postMessage", "runtime.connect", "Protocol Map", "@webext-core/messaging", "message passing", "extension IPC", "sendMessage vs connect", "async message response", "return true onMessage", "typed messaging", "message schema".

From the source SKILL.md

All extension contexts are strictly siloed — no shared memory. Communication happens exclusively through async message passing with JSON-serializable data. Choose the right pattern for each use case and enforce type safety through Protocol Maps.

What this skill does

Chrome Ext Messaging 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-messaging/ and loads when your prompt matches the skill's trigger.
