❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title mentions 'OpenAPI Type Gen support in Cloudflare Workers' which aligns with the documentation changes about requiring nodejs_compat for OpenAPI Type Gen, but the PR objective emphasizes 'fs (filesystem) support in cloudflare workers' as the primary purpose.	Clarify whether the main focus is OpenAPI Type Gen support or filesystem support in Cloudflare Workers, then adjust the title to accurately reflect the primary objective.

68-68: Clarify why nodejs_compat is needed for OpenAPI Type Gen.

The documentation states that nodejs_compat is required for OpenAPI Type Gen but doesn't explain why. Given that the PR objective is about "fs support in Cloudflare Workers," consider explicitly mentioning that nodejs_compat enables filesystem API support, which OpenAPI Type Gen depends on. This would better align with the PR intent and provide more context to users.

Consider updating the text to something like:

- You don't need a `nodejs_compat` flag for basic usage. However, if you want to use [OpenAPI Type Gen](/blog/openapi-type-gen), you'll need to enable it with compatibility_date 2025-09-01 or later.
+ You don't need a `nodejs_compat` flag for basic usage. However, [OpenAPI Type Gen](/blog/openapi-type-gen) requires the `nodejs_compat` flag to enable filesystem API support. Set compatibility_date to 2025-09-01 or later in your wrangler config.

79-80: Verify and expand documentation scope on fs support.

While the changes clarify nodejs_compat requirements for OpenAPI Type Gen, the PR objective mentions adding documentation for "fs (filesystem) support in Cloudflare Workers" but no explicit fs capabilities or usage examples are included. Consider whether the documentation should also include:

• A brief mention that nodejs_compat enables Node.js filesystem APIs
• A reference link to Cloudflare's fs runtime API docs (mentioned in PR)
• Simple examples of using fs in Cloudflare Worker context

This would better fulfill the PR objective of documenting fs support.
