learning-hour-mcp: Instructions file for Claude Code

CLAUDE.md

learning-hour-mcp CLAUDE.md is an instructions file for Claude Code from SDiamante13/learning-hour-mcp. It costs 774 tokens per session, scanned A, original, MIT.

A project guide for an MCP server that helps technical coaches create 60-minute team practice sessions called Learning Hours. It documents the project structure, commands, architecture, and development rules.

In plain words
What is it for?
Use it when developing the TypeScript server, running its build or tests, or working on repository and technology-stack analysis.
Why use it?
It gives a coding agent the context needed to build, test, and change the project consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

learning-hour-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a TypeScript-based MCP (Model Context Protocol) server that helps Technical Coaches generate comprehensive Learning Hour content. Learning Hours are 60-minute structured practice sessions where teams develop technical excellence skills through deliberate practice.

Common Development Commands

  • npm run build - Compile TypeScript to JavaScript
  • npm run dev - Run in development mode with hot reload (tsx)
  • npm test - Run all tests
  • npm run test:integration - Run integration tests only

Architecture

The codebase follows a clean architecture with these key components:

  • src/index.ts - MCP server entry point, defines available tools
  • src/LearningHourGenerator.ts - Generates Learning Hour session content using enhanced prompts that deeply incorporate 4C model
  • src/RepositoryAnalyzer.ts - Analyzes GitHub repositories for code examples
  • src/TechStackAnalyzer.ts - Identifies technology stack in repositories
  • src/schemas.ts - Zod schemas for input validation
  • src/EnhancedMiroBuilder.ts - Creates beautiful, workshop-ready Miro boards with visual 4C flow
  • src/MiroBoardPrompt.ts - Sophisticated prompt for Miro board visual design

The server integrates with:

  • Anthropic API for AI-powered content generation with carefully crafted prompts
  • Other MCP servers (specifically miro-mcp) via subprocess spawning for MCP-to-MCP communication

Development Guidelines

  1. Code Style: Follow clean code principles - no comments, small focused functions, expressive naming
  2. Testing: Write tests in __tests__/ directory using Jest
  3. Environment: Requires ANTHROPIC_API_KEY in environment variables
  4. TypeScript: Strict mode enabled, target ES2020

Key Domain Concepts

  • Learning Hour: Structured 60-minute practice session following 4C model
  • 4C Learning Model:
    • Connect (10 min): Share experiences, connect to existing knowledge
    • Concept (10 min): Introduce new ideas, discuss theory and principles
    • Concrete (30 min): Hands-on practice with pair programming and coding
    • Conclusion (10 min): Reflect, commit to apply learning, share insights
  • Technical Excellence: Focus on TDD, refactoring, clean code, evolutionary design
  • Deliberate Practice: Focused improvement with immediate feedback

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
