Claude code best Practices

Source: Dev.to

Fundamental

Essential commands: Bash mode (cmd)

• Make documentation
• create todo list
• shift+tab or /model: change model
• Check memory: /memory
• space key or esc: press once to interrupt, press twice to go back to the previous prompt in your session

Debugging

• Screenshot
• Write test for flow or feature
• Using TDD by Claude

Make Claude.md

• Project Overview: Appname, platform, tech stack, architecture, …
• Getting current Date: (notes for tech stack, …)
• Todo list
• Development Environment
• Common build issues & Solutions
• Testing & debugging
• Common mistakes to avoid
• Feature Development workflow
• Documentation Structure
• Message queue: means you prompt and the agent processes while you type a new prompt; they push into a queue and process later, which can affect the previous prompt.
• Long prompt: should be pushed to prompt.md stage markdown file

Intermediate

Using GitHub workflows

• Planning and thinking features
• Use Planning mode: choose model by command /mode
• Thinking modes: think < think hard < think harder < ultra think
• Using research: read linked docs and research how to build an API … or read a PDF to implement …
• Create PRDs: features, user‑experience guides, API, documentation, and technical design docs.
• Automatic change tracking: /changelog day

GitHub Action Integration

• /install-github-app: trigger actions by commenting on a pull request

Think like a product manager

• Provide clear, relevant context and constraints based on the markdown file
• Review code and verify that everything implemented works, checking output at higher levels of abstraction

Master

Using multiple agents

• Use parallel sub‑agents to brainstorm … (and choose one)

Collaborate with Git worktree

• git worktree add {address location} and prompt to create features
• When done, ask the agent to merge each worktree into one folder and resolve any conflicts

Custom slash commands

• /changelog
• /create-command

Subagents

• Command /agents to create a sub‑agent that delegates task handling

MCP server

• Database MCP examples: mongodb-mcp, postgres-mcp, supabase
• Interactive with browser: click on UI
• Figma MCP
