Ready-to-use content

I. Understanding Claude Code's seven-layer architecture

The article introduces Claude Code's seven-layer architecture to help users build a systematic understanding:

1. Model layer (Claude Opus 4.7)

2. Tool layer (file operations, Bash, search, and more)

3. Context layer (CLAUDE.md, memory system)

4. Workflow layer (Skills, Subagents)

5. Automation layer (Hooks)

6. Integration layer (MCP servers)

7. Collaboration layer (shared team configuration)

II. 14 principles that double productivity

The article summarizes 14 core principles, including:

• Define goals and constraints clearly

• Make effective use of the Context Window's available space

• Establish project memory with CLAUDE.md

• Assign effort levels appropriately

• Avoid overreliance on the model's memory

• Validate and test promptly

• And more

III. Context Window management: your most valuable resource

Core principle: The Context Window is a finite resource and needs to be managed carefully

Tips:

• Use /context to view current context usage

• Avoid handling too many unrelated tasks in a single session

• Use /memory regularly to check the loaded memory rules

• For long tasks, consider splitting them across multiple sessions

IV. The essentials of writing CLAUDE.md

Standard structure:

# CLAUDE.md

## Project Goals
- Clearly define the project's core goals and scope

## Prohibitions
- List things that must never be done
- Example: Do not modify the production database; do not delete specific files

## Test Commands
- npm test
- pnpm test -- <file>

## lint / typecheck Commands
- npm run lint
- npm run typecheck

## PR / branch Rules
- Branch naming conventions
- PR description requirements
- Code review standards

## Common Pitfalls
- Known traps and caveats in the project
- Example: An API compatibility issue

V. Core workflow: Explore → Plan → Implement → Verify

Four-step workflow:

1. Explore:

   • Use /explore or ask Claude to analyze the codebase

   • Understand the existing architecture and patterns

2. Plan:

   • Use /plan fix the auth bug to enter Plan Mode

   • Have Claude propose a solution without executing it immediately

3. Implement:

   • Execute the plan after confirmation

   • Use /effort medium to adjust the reasoning effort

4. Verify:

   • Run tests and checks

   • Verify that the implementation meets expectations

VI. Prompt techniques: make instructions ten times more precise

Core techniques:

• Use specific, unambiguous instructions

• Provide sufficient context

• Specify the output format

• Use $ARGUMENTS to pass parameters

• Avoid vague instructions

Example:

❌ Vague: Fix this bug
✅ Specific: Fix the token expiration issue during user login and return a 401 status code

VII. Advanced systems: Skills, Subagents, and Hooks

Skills:

• Reusable workflow templates

• Stored in .claude/skills/

• Invoked with /skill-name

Subagents:

• Agents dedicated to specific tasks

• Used for complex, multistep tasks

• Parallel processing and context isolation

Hooks:

• Automation tools

• Configuration file: .claude/settings.json

{
  "hooks": {
    "PostToolUse": [{
      "matcher": "Edit|Write",
      "hooks": [{
        "type": "command",
        "command": "cd $CWD && npm test --bail 2>&1 | tail -10"
      }]
    }]
  }
}

VIII. MCP servers: connecting to the outside world

Adding an MCP server:

claude mcp add -s user playwright npx @playwright/mcp@latest

Common MCP servers:

• Playwright (browser automation)

• PostgreSQL (database access)

• Linear (project management)

IX. Parallel development across multiple Sessions

Using Git Worktrees:

# Create an independent worktree for each feature
git worktree add ../feature-auth feature/auth
git worktree add ../feature-payments feature/payments

# Run a separate Claude session in each worktree
cd ../feature-auth
claude

# In another terminal
cd ../feature-payments
claude

Batch processing script:

for file in $(cat files-to-migrate.txt); do
  claude -p "Migrate $file from class to hooks" \
    --allowedTools "Edit,Bash(git commit *)" &
done
wait

X. Daily efficiency: Top 15 tips

The article lists the 15 most practical everyday tips, including:

1. Use /init to initialize project configuration

2. Use /memory to check memory rules

3. Use /permissions to manage the permissions allowlist

4. Use /hooks to manage automated hooks

5. Use /context to view context usage

6. Use /usage to view quota and rate limits

7. Use /plan to enter Plan Mode

8. Use /effort to adjust reasoning effort

9. And more

XI. Common errors and pitfalls to avoid

Common errors:

• Overrelying on the model's memory instead of updating CLAUDE.md

• Handling too many tasks in a single session

• Failing to validate and test promptly

• Using vague instructions

• Ignoring Context Window limits

• Failing to configure Hooks for automation

Pitfall-avoidance advice:

• Update CLAUDE.md regularly

• Split long tasks across multiple sessions

• Use Plan Mode to plan before executing

• Configure PostToolUse Hooks for automated testing

• Use /context to monitor context usage

XII. The shortest executable configuration

Minimal configuration example:

# Create the basic directory structure
mkdir -p .claude/commands .claude/skills .claude/agents

# Create a minimal CLAUDE.md
cat > CLAUDE.md << 'EOF'
# Project Goals
- Define the goal

# Prohibitions
- Do not modify the production database

# Test Commands
- npm test

# Common Pitfalls
- API compatibility issue
EOF

# Create a basic command
cat > .claude/commands/code-review.md << 'EOF'
Review git diff --staged, checking for bugs, security issues, and code quality.
Format: ## Summary, ## Issues (Critical/Warning/Suggestion), ## Conclusion
EOF

XIII. Commands most worth using immediately

Frequently used commands:

• /init - Initialize project configuration

• /memory - Check loaded memory rules

• /permissions - Manage the permissions allowlist

• /hooks - Manage automated hooks

• /context - View context usage

• /usage - View quota and rate limits

• /plan <task> - Enter Plan Mode to handle a specific issue

• /effort <level> - Set reasoning effort (low/medium/high/xhigh)
