Which backend frameworks are supported by this skill?

While the skill is optimized for Cloudflare Workers and Hono, it provides best-practice guidance for any existing backend service that follows a repo-first workflow.

What kind of verification does it provide?

It provides repo-native checks including targeted unit tests, linting, type-checking, and specific runtime verification for input validation and idempotency.

Can I use this for greenfield architecture design?

This skill is specifically designed for patching and extending existing codebases. For entirely new systems, it is recommended to use a general design or architecture skill.

How does this skill ensure deployment safety?

It generates a 'smallest-safe-change' plan, requires concrete verification commands, and explicitly documents risks regarding data integrity and rollback paths.

API Development

Plans and reviews safe backend extensions for existing services with a specialized focus on Cloudflare Workers and Hono frameworks.

The Backend Engineer skill transforms Claude into a senior-level architect focused on the safe modification and extension of existing backend systems. It moves beyond simple code generation by enforcing a rigorous workflow that prioritizes service contracts, data integrity, and operational visibility. Whether you are patching API handlers, adding background jobs, or integrating new storage modules, this skill ensures that every change is accompanied by concrete verification steps, idempotency checks, and explicit rollback strategies to minimize production risk.
