30-36: Consider making docs copy conditional.Since the copy command runs on all workflow triggers (including PRs), consider making it conditional to run only when publishing.

4-13: LGTM! Package metadata updates look good.
The version bump and added metadata fields follow npm standards and provide better discoverability of the project.

💡 Codebase verification
Remove docs directory from copy command as it's not meant to be published
The files array in socket.io-serverless/package.json explicitly lists what should be included in the published package, and the docs directory is not included. The workflow should only copy README.md:
- - run: cp -v README.md docs ./socket.io-serverless/
+ - run: cp -v README.md ./socket.io-serverless/🔗 Analysis chain
Verify docs directory inclusion in package files.
The workflow now copies both README.md and the docs directory, but the package.json files array doesn't include the docs directory. This means the docs won't be included in the published package.
Either:
- Add "docs" to the
filesarray in package.json if you want to include the documentation in the published package, or - Remove "docs" from the copy command if it's not meant to be published.
Let me gather more information to verify the package.json files configuration.
Let me check the contents of the docs directory and the package.json to better understand the publishing configuration.
Let me check the package.json in the socket.io-serverless directory since that's where the files are being copied to.

| ### how socket.io works | ||
|
|
||
| Socket.io (the top level library) have 2 main components: npm packages `socket.io` and `engine.io`. | ||
|
|
||
| The `socket.io` packages deals with the high level concepts: namespace / room / clustering / etc. It depends on `engine.io` which holds a `http.Server` instance and deals with the transport-aware logic. | ||
|
|
||
| In Node.js the 2 components just run in the same process, communicate with a event emitter API. |

🛠️ Refactor suggestion
Enhance technical accuracy and clarity of Socket.io architecture explanation
The current explanation needs improvement in several areas:
- Grammar: "Socket.io packages have" instead of "have", "communicates with an event emitter" instead of "communicate with a event emitter"
- Technical accuracy: Add details about the Engine.IO protocol, transport upgrades, and the relationship between Socket.IO server and client
Consider this revision:
-Socket.io (the top level library) have 2 main components: npm packages `socket.io` and `engine.io`.
-
-The `socket.io` packages deals with the high level concepts: namespace / room / clustering / etc. It depends on `engine.io` which holds a `http.Server` instance and deals with the transport-aware logic.
-
-In Node.js the 2 components just run in the same process, communicate with a event emitter API.
+Socket.IO (the top-level library) has two main components: the `socket.io` and `engine.io` packages.
+
+The `socket.io` package handles high-level concepts like namespaces, rooms, and clustering. It builds upon `engine.io`, which manages the underlying transport protocol, including:
+- Transport selection and upgrades (polling → WebSocket)
+- Connection state management
+- Packet encoding/decoding
+
+In a Node.js environment, these components operate within the same process, communicating through an event emitter API. The `engine.io` server attaches to an HTTP server instance to handle both HTTP long-polling and WebSocket connections.📝 Committable suggestion
