Introduction

Claude Commands Library is a collection of three slash commands for Claude Code that improve how you write prompts and research codebases.

Why Use This Library?

Without it

You: "Add authentication to my app"
Claude: *implements basic username/password*
You: "No, I meant OAuth with Google"
Claude: *refactors to OAuth*
You: "And I need JWT tokens for the API"
Claude: *adds JWT layer*

Result: 3 rounds of back-and-forth, wasted tokens, fragmented implementation.

With /prompt

You: /prompt Add authentication to my app

Claude: Before you proceed, let me clarify:

1. Which authentication method?
   - Option A: OAuth (Google, GitHub, Microsoft)
   - Option B: JWT with username/password
   - Option C: Session-based with cookies

2. Which providers should you support?

3. Where should user data be stored?
   - Your existing Users table
   - New OAuth-specific tables

You: OAuth, Google only, existing Users table

→ Structured prompt ready. Hand it to Claude for precise implementation.

Result: One clear conversation. Correct implementation on the first attempt.

The Three Commands

/prompt — Analyses any prompt, asks targeted questions, and rewrites it into a structured executable form.

/prompt-article-readme — Scans your project and generates or updates README.md matched to the detected stack.

/prompt-research — Multi-step research for unfamiliar codebases. Spawns parallel agents, iterates on findings, produces a cited report.

Core Concept: Phase 0

Every command begins with Phase 0 — a shared validation layer that:

1. Detects what you're asking (task, question, bug fix, etc.)
2. Recalls known facts from project memory
3. Checks for missing information
4. Asks only genuinely unknown questions
5. Structures the result into a clear format
6. Waits for your approval
