Mastering Claude Code: From AI Development Workflow Basics to Real-World Practice

Hello, I'm GymCoding!

• "I'm so overwhelmed by the cost of Claude Code tokens"

• I've been getting so many questions like, "I don't know where my tokens are leaking."

So, I’ve put together an additional lecture to properly address this!

This lecture is not just about simple token-saving tips. It is a practical guide that selects only 4 plugins directly related to token saving from the 171 plugins in the Anthropic official marketplace, covering everything from measurement to automatic blocking in one go.

What we will cover in this lesson

• Where tokens are leaking shown on one screen: How to use session-report — How to analyze token usage by project and prompt, and identify the most expensive prompts using an HTML dashboard

• How to reduce the token tax on every turn using two tools from CLAUDE.md management (revise + improver) to keep your claude-md-management clean, which automatically attaches to every request

• serena MCP, which searches for code by meaning rather than just characters — from the reason it was picked as the #1 tool for saving tokens to installing uv package manager dependencies

• hookify, which prevents Claude's mistakes in advance — among the four, this is the only official tool that goes beyond simple token saving to assist with the core of harness engineering

• The entire workflow to install and activate all four with a single-line command from the Anthropic official marketplace

The core of this lecture is a bundle of practical tools that will help you save tokens using official tools curated directly by Anthropic, and even reach harness engineering with the final one!
