How does this skill prevent I/O context errors in Cloudflare Workflows?

The skill provides specific patterns to ensure all I/O operations are performed within step.do() callbacks, preventing the common 'Cannot perform I/O on behalf of a different request' error.

Does it help with state persistence during workflow hibernation?

Absolutely. It teaches developers to only rely on values returned from step.do() and avoid ephemeral in-memory variables that are lost when the workflow engine hibernates.

Can I use this to troubleshoot local development issues with wrangler?

Yes, the skill documents specific bugs in the local emulator (miniflare), such as waitForEvent timeouts and unimplemented instance management APIs, providing reliable workarounds.

What testing frameworks are supported for Cloudflare Workflows?

The skill focuses on Vitest using the @cloudflare/vitest-pool-workers package, including advanced techniques like introspectWorkflowInstance and mockStepResult.
