なぜからどうやってへ：Claude Code完全学習パス

Most Claude Code resources fall into one of two traps. Either they explain everything from first principles — what MCP is, why Hooks exist, how context windows work — without ever showing you a concrete command to run. Or they dump a list of slash commands and config snippets with no explanation of why you'd use them.

Neither is wrong. But if you're coming from no-code tools like Zapier, Make, or Notion, you need both. You need the "why" before the "how" makes sense. And once you understand the why, you want the how immediately at your fingertips.

That's the gap claude-study and Claude Code Catalog are designed to fill — together.

claude-study (github.com/minjikim89/claude-study) is a 17-chapter learning repository written for people coming from no-code backgrounds. Every chapter starts with a familiar tool — Zapier, Notion, Chrome extensions — and builds a bridge to the corresponding Claude Code concept. It's Korean-first, concept-first, and deliberately avoids copy-paste shortcuts.

Claude Code Catalog (this site) is the practical reference layer. Searchable Skills, Plugins, MCP Servers, Hooks, Patterns, and Guides — with install commands, terminal demos, and difficulty ratings. It assumes you already know what you want and need to know how to get there fast.

The intended flow:

``` claude-study → Claude Code Catalog ────────────────────────────────────────────────── "What is MCP?" → Browse MCP Servers "How do Hooks work?" → Copy a Hook config "What are Channels?" → Install Telegram plugin ```

Here's how the two resources map to each other at each learning stage.

Stage 1 — Basics (claude-study ch. 01–03)
  → How Claude Code works, memory, Skills
  → Catalog: Skills section (61 skills across 8 categories)

Stage 2 — Agents (claude-study ch. 04–06)
  → Subagents, Agent Teams, vs agentic frameworks
  → Catalog: Patterns section (agent-teams, parallel-tasks)

Stage 3 — Integrations (claude-study ch. 07–10)
  → MCP, Hooks, context management, real workflows
  → Catalog: MCP Servers (11 servers), Hooks (11 hooks)

Stage 4 — Advanced (claude-study ch. 11–16)
  → MCP+API hybrid, Skill vs Rule, Plugins, Scheduled Tasks,
    Remote Control, Channels
  → Catalog: Plugins section (Telegram/Discord channel plugins)

If you're just getting started with Claude Code and come from a no-code background, here's the recommended entry sequence:

1. Read claude-study chapters 01–03 to understand how Claude Code thinks — memory hierarchy, CLAUDE.md, Skills as prompt injection. 2. Come back to this Catalog and browse the Skills section. Pick one skill in a category you care about. Copy it into your CLAUDE.md. 3. Read claude-study chapters 07–08 for MCP and Hooks. 4. Return to Catalog to browse MCP Servers and Hooks. Install one that connects to a tool you already use. 5. Repeat.

The key insight is that you don't need to read everything before you start using Claude Code. The goal is to build a mental model fast enough that the Catalog entries make sense on first read.

Claude Code Channels (research preview) is a good example of how the two resources complement each other.

claude-study chapter 16 explains the core mental model: Channels are the inverse of MCP. Standard MCP is pull — Claude queries a service when it needs data. Channels are push — an external system (Telegram bot, Discord DM, CI webhook) delivers an event to a running session, and Claude responds through the same channel. The chapter builds this understanding through ASCII diagrams and a side-by-side comparison with Remote Control and Scheduled Tasks.

Once that clicks, the Catalog's Telegram Channel and Discord Channel plugin entries become immediately useful — they show the exact install command, token configuration, and a terminal demo of the full setup flow. The concept from study turns into a working integration in minutes.

If you're introducing Claude Code to a team or running a workshop, the two-resource structure works well as a curriculum:

- Use claude-study as pre-reading or session material. The no-code comparisons make onboarding faster for non-developer teammates. - Use Claude Code Catalog as the hands-on reference during and after sessions. The search and filter make it easy to find relevant examples in context.

Both repositories are open source. claude-study docs are available in Korean (primary), English, and Japanese. The Catalog supports all three languages with full i18n.

Both resources update in sync when new Claude Code features ship. The most recent addition covers the Channels research preview — Telegram and Discord plugins that let you push events into a running local session from your phone.

Upcoming additions planned for claude-study: - Chapter 17: Auto Mode (automated permission approval for long sessions) - Chapter 03 update: Skills system evolution — bundled skills (/simplify, /batch, /debug, /loop, /claude-api), $CLAUDE_SKILL_DIR, context:fork
