Pruébalo

Usando "workers-best-practices". Review a handler that stores the current user in a module variable.

Resultado esperado:

High: request-scoped data is stored in module state and can leak between reused isolates.
Use function parameters or local variables for request-specific values.

Usando "workers-best-practices". Review a configuration that stores an API key in vars.

Resultado esperado:

High: the configuration contains a secret that can enter version control.
Store the value with Wrangler secrets and keep only non-secret settings in vars.

Usando "workers-best-practices". Review a large upstream response that uses response.text().

Resultado esperado:

Medium: buffering an unbounded response can exceed the Workers memory limit.
Return the response body as a stream or process it incrementally.

The 92 static findings are false positives caused by Markdown code spans, illustrative Worker code, safe secret-handling guidance, and public documentation URLs. No prompt injection, credential exfiltration, or hidden execution behavior was found. The skill does instruct users to retrieve and extract an unpinned package, which warrants controlled execution.

Unpinned package retrieval and archive extraction

The skill directs the assistant to download the latest published @cloudflare/workers-types package and extract it into a shared temporary path. This creates a supply-chain and local temporary-directory exposure unless users review the package source and isolate the workspace.

Both files explicitly require retrieving the latest package and extracting its archive into /tmp. The exposure is real, although the named package is legitimate and no malicious intent is present.

Lo que puedes crear

Review a Worker before release

Identify configuration, type, security, and runtime issues before a production deployment.

Set up a new Worker project

Create a configuration and handler structure that follows current Workers patterns.

Standardize team reviews

Apply a repeatable checklist for bindings, streaming, observability, and error handling.

Prueba estos prompts

Beginner: review one handler

Review this Cloudflare Worker handler for the most important production issues. Explain each issue and show the corrected approach.

Intermediate: check configuration

Review this wrangler.jsonc and Worker code together. Check binding names, secrets, compatibility settings, and observability.

Advanced: assess performance

Analyze this Worker for buffering, floating promises, global request state, and unnecessary network calls. Prioritize fixes by production impact.

Expert: complete release review

Perform a release review of these Worker files. Retrieve current Workers guidance first, then report verified findings with severity, evidence, and remediation.

Mejores prácticas

Retrieve current Workers documentation and type definitions before making API-specific recommendations.
Provide file and line evidence for each finding and distinguish verified issues from suggestions.
Review configuration and source code together so binding names and secret handling stay consistent.

Evitar

Do not treat bundled examples as a substitute for the project's current Workers types and configuration.
Do not hardcode secrets or recommend storing credentials in Wrangler vars.
Do not buffer unbounded request or response bodies when streaming is appropriate.

Preguntas frecuentes

What does this skill review?

It reviews Cloudflare Workers code and Wrangler configuration for production practices, type safety, performance, and security.

Does it use current Cloudflare guidance?

It instructs the assistant to retrieve current Cloudflare documentation and Workers type definitions before API-specific advice.

Can it deploy my Worker?

No. It provides guidance and review findings. Deployment requires separate tools and authorization.

Can it find secrets?

It checks for common hardcoded secret patterns and recommends Wrangler secret storage. It cannot guarantee that all credentials are detected.

Does it support Durable Objects and Workflows?

It covers shared binding and class patterns, then directs specialized topics to the relevant documentation or skill.

Should I run its package retrieval commands automatically?

No. Review the package name and network policy first. Use trusted registries and a controlled temporary directory.
