[Claude Code] Claude Code Study Guidelines to Learn Efficiently and Quickly

April 3, 20261 min read

Basic Usage

Claude.md Setup Study

1. Create md files for each folder.
2. make root md not big
3. Trigger recurring tasks (e.g., deploy)

plan edits, accept edits classification

1. Accept Mode: I can even change the file on my own
2. Plan Mode: Tells you what to do.
3. The plan mode uses fewer tokens because it only plans. The accept mode greatly consumes tokens. I started working right away...

ESC button

1. Interruption during work. 
2. Double press esc to “undo function”

Drag to upload image

iTerm Terminal

  1. cmd + D (Split panel length) 2. cmd + shift + D (panel horizontal division) 3. Move between cmd + [/cmd +] panels

Run the terminal Bash command

1. From the prompt! Paste in front of it to execute the terminal command right away

Slash command

Context Management

    1./contact,/clear/compact
    2. contact checks token usage, clear token, compact compresses to reduce token amount

Model management (/models)

    1. opus, sonnet, haiku 
    2. Smartest, Balanced, Fastest

3. Pro version is for sonnet only. Opus requires a fee of Max 4. Coding operation is suitable for opus, when working with agents to save tokens, sub operation is done with sonnet

resume command

1. Revert to task when session is closed
2. Return to/resume.

mcp command

1. The mcp server I use 
2. Think of it as a tool used by ai (weapons) The more you put in, the more tokens you'll get, so we recommend `custommcp'
3. Connect external tools (Notion, Slack, GitHub)

Other

1./help,/config,/export,/output-style

2. Help, settings, chat view (when moving to cursor, etc.), response style setting (learning mode, concise mode, etc.) 3. The response style setting running mode allows → me to write it myself so that I can learn it.

Create a command

1. If you make it a recurring task slash command, it can be repeated/pressed to float and execute in the list.
2. Able to execute repetitive tasks more reliably than the trigger

Next Level....
Create Skills, Sub-Agent, Hooks, MCP

PM

A 40-something PM returns to code. Learning, failing, and growing.
