Is the Backend Development Patterns skill free?

Yes. The skill itself is free from xiaobei930/cc-best. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Backend Development Patterns SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Backend Development Patterns?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Backend Development Patterns with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 91c119a

Ran a real A/B on an Express POST /orders handler: baseline used ad-hoc try/catch and console.log with an inconsistent error shape, while the skill-guided version produced an AppError/ValidationError hierarchy, a requestId-tagged structured JSON logger, and a unified {success,data}/{success:false,error:{code,message}} envelope pulled straight from the skill's TypeScript reference file — a concretely more production-grade result.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Backend Development Patterns does

Gives Claude a concrete backend playbook: layered architecture, an error-code pyramid (400s/500s), structured JSON logging fields, cache-key naming, and a unified success/error response envelope, with per-language deep dives (Python/TS/Java/Go/C#/Rust) loaded on demand. Triggers when building backend services, APIs, or microservices, or when adding error handling, logging, or caching to existing server code.

How to install Backend Development Patterns

git clone https://github.com/xiaobei930/cc-best
cd cc-best
mkdir -p ~/.claude/skills
cp -r skills/backend ~/.claude/skills/backend

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Backend Development Patterns

/backend Layered backend patterns: errors, logging, caching, and API conventions across 6 languages.

It also activates on plain-language prompts like these:

Add error handling and structured logging to this Express endpoint
Design a unified success and error response envelope for my API
Set up cache-key naming conventions for this Go microservice
