1

Give Claude Verification Criteria

The single most impactful thing you can do: tell Claude how to verify its own work. Tests, type checks, screenshots, linting β€” give Claude a way to confirm success.

Best Practices:

  • β€’ Include test commands: 'fix the bug and make sure all tests pass'
  • β€’ Provide verification steps: 'run the linter after making changes'
  • β€’ Use screenshots for visual verification with /chrome or Playwright MCP
β€œThe most effective prompts include success criteria, not just instructions.”
2

Explore First, Then Plan, Then Code

Don't jump straight into code changes. Let Claude understand the codebase first, then plan the approach, then execute.

Best Practices:

  • β€’ Start with 'explore this codebase and explain the architecture'
  • β€’ Use Plan Mode (Shift+Tab) for complex tasks
  • β€’ Review the plan before letting Claude write code
β€œThe explore-plan-code workflow prevents most failures before they happen.”
3

Provide Specific Context with @ and Images

Reference specific files with @filename, paste screenshots and error images, and give Claude exactly the context it needs.

Best Practices:

  • β€’ Use @ to reference specific files in your prompts
  • β€’ Paste screenshots of errors, UIs, or designs
  • β€’ Copy-paste error messages and stack traces directly
  • β€’ Reference documentation URLs for Claude to fetch
β€œThe more specific your context, the more accurate Claude's response.”
4

Write Effective CLAUDE.md Files

Your CLAUDE.md is the single most important configuration. Keep it short, specific, and regularly pruned. Bad CLAUDE.md = bad results.

Best Practices:

  • β€’ Keep it concise β€” under 500 lines for project-level
  • β€’ Include build/test/lint commands Claude should use
  • β€’ Add code style preferences and conventions
  • β€’ Prune regularly β€” remove outdated or redundant instructions

⚠️ Warning: A long, unfocused CLAUDE.md hurts more than it helps. Quality over quantity.

5

Manage Context Aggressively

Context window management is critical. Use /clear, /compact, /btw, and fresh sessions to keep Claude performing at its best.

Best Practices:

  • β€’ Start fresh conversations for new topics (/clear)
  • β€’ Use /compact to compress long conversations
  • β€’ Use /btw for side questions that don't pollute main context
  • β€’ Use subagents for isolated investigation tasks
β€œAI context is like milk β€” best served fresh and condensed.”
6

Use Subagents for Investigation

Spawn subagents to explore, investigate, and research without consuming your main session's context. Results come back summarized.

Best Practices:

  • β€’ Use the Explore subagent (Haiku, read-only) for quick lookups
  • β€’ Use the Plan subagent for complex analysis without code changes
  • β€’ Create custom subagents for recurring investigation patterns
  • β€’ Run subagents in background with Ctrl+B

CLAUDE.md Tip: Subagents have their own context windows, so they don't consume tokens from your main session.

7

Rewind with Checkpoints

Claude automatically creates git checkpoints. Use /rewind to go back if something goes wrong. Course-correct early with Esc.

Best Practices:

  • β€’ Use /rewind to restore previous state
  • β€’ Press Esc early if Claude is going in the wrong direction
  • β€’ Check git diff after changes to verify correctness
  • β€’ Use /clear to reset if the conversation derails
β€œCourse-correct early. The cost of rewinding goes up with every additional change.”
8

Configure Permissions and Hooks

Set up permission modes and hooks to automate repetitive approvals and enforce team standards.

Best Practices:

  • β€’ Use permission modes: default, acceptEdits, dontAsk, plan
  • β€’ Set up hooks for auto-formatting after edits
  • β€’ Use hooks to enforce security policies on tool usage
  • β€’ Configure allowed/disallowed tools per project
9

Use CLI Tools and MCP Servers

Claude works best when it has access to the right tools. Connect GitHub CLI, AWS CLI, database tools, and MCP servers.

Best Practices:

  • β€’ Install gh (GitHub CLI) for PR and issue management
  • β€’ Connect MCP servers for databases, Slack, and more
  • β€’ Use claude mcp add to register new servers
  • β€’ Create custom skills to teach Claude your tool workflows
β€œClaude + CLI tools + MCP = a development workflow that covers everything.”
10

Create Custom Skills and Subagents

Build reusable skills (SKILL.md files) for domain knowledge and custom subagents for specialized tasks.

Best Practices:

  • β€’ Create skills for team conventions and code standards
  • β€’ Build subagents for code review, debugging, data analysis
  • β€’ Share skills and agents across your team via plugins
  • β€’ Use /agents command to create subagents interactively
β€œSkills and subagents turn Claude from a generic assistant into a domain expert.”
11

Avoid Common Failure Patterns

Know the anti-patterns that lead to poor results and avoid them proactively.

Best Practices:

  • β€’ Don't dump entire codebases into context
  • β€’ Don't give vague instructions like 'make it better'
  • β€’ Don't skip verification β€” always include test/lint/check commands
Common failures to avoid:
Too much context, vague instructions, no verification, ignoring Plan Mode for complex tasks
β€œMost failures come from too much context, not too little.”

Quick Tips

🎯 Alias 'claude' to 'c'

Add 'alias c=claude' to your shell config. Use 'c -c' to continue, 'c -r' to resume.

πŸ”„ Use Voice Input

Hold Space to dictate. Claude handles transcription mistakes gracefully.

πŸ§ͺ Multiple Sessions

Run multiple Claude instances for parallel tasks. Use git worktrees for isolation.

πŸ” Pass Context Between Sessions

Ask Claude to write a HANDOFF.md before starting fresh. Load it in the next session.

Claude Code is a genuinely transformative tool

These tips come from real developers and official best practices. Start with verification criteria (tip #1) and context management (tip #5). The productivity gains compound as you master each technique.
