Test it

Using "pitfalls-express-api". Review an Express router with list, create, update, and delete endpoints.

Expected outcome:

A concise route review that flags verb mismatches, missing validation, and incorrect success status codes.

Using "pitfalls-express-api". Plan storage support for a new Express resource.

Expected outcome:

A storage interface outline with operations for read, create, update, delete, database storage, and test storage.

Using "pitfalls-express-api". Check a scheduled background task in an API service.

Expected outcome:

A review note covering interval cleanup on shutdown and protection against overlapping task executions.

The static findings are false positives caused by Markdown code fences, HTTP route examples, and benign JavaScript examples. I found no prompt injection, malicious intent, unauthorized network behavior, credential access, or real external command execution in SKILL.md.

What You Can Build

Review API Routes

Check route names, HTTP verbs, and admin path placement before merging backend changes.

Standardize Status Codes

Align GET, POST, PATCH, and DELETE handlers with clear success and error responses.

Plan Storage Abstractions

Define a storage interface that supports database implementations and in-memory test backends.

Try These Prompts

Check Basic Routes

Review my Express routes for REST naming, HTTP verbs, and public versus admin route placement.

Validate Status Codes

Compare my Express handlers against standard status codes for GET, POST, PATCH, and DELETE operations.

Improve Storage Design

Help me design a storage interface for this Express API with database and in-memory implementations.

Audit API Workflow

Audit this Express API for route structure, request validation, storage boundaries, and background job cleanup.

Best Practices

Validate request bodies before calling storage methods.
Keep public read routes separate from authenticated admin write routes.
Clear background intervals during process shutdown.

Avoid

Returning inconsistent status codes for the same CRUD operation.
Writing directly to storage before validation finishes.
Starting repeated jobs without overlap protection.

Frequently Asked Questions

What does this skill help with?

It helps review Express API route structure, status codes, validation, storage interfaces, and background job patterns.

Does it generate a full application?

No. It provides conventions and review guidance for existing or planned Express API code.

Can it help with status codes?

Yes. It lists expected success, not found, and invalid request codes for common CRUD operations.

Does it include authentication code?

No. It only recommends separating admin routes and using authentication middleware where needed.

Can it support testing plans?

Yes. It encourages storage interfaces that can use database implementations and in-memory test implementations.

Which tools can use this skill?

The report lists compatibility with Claude, Codex, and Claude Code.
