7 Proven Tricks to Supercharge Claude Code

Keep CLAUDE.md Concise

Write the CLAUDE.md file under 150 lines and include only information the AI cannot infer from the code, such as build commands, immutable files, and project‑specific conventions. Adding excess text consumes context and slows down Claude Code.

Plan Mode First

When a task is complex, press Shift+Tab to switch to planning mode. Claude generates a plan that you review before any code is produced, reducing the need for repeated trial‑and‑error edits.

Run Parallel Sessions

Use git worktree to create separate work directories for different tasks, allowing three or four Claude instances to operate independently without interfering with each other.

Never Skip Validation

Claude Code’s official guidance emphasizes that a task is only complete after linting, testing, and type‑checking all pass. Run these checks and accept the result only when every check succeeds.

Clear a Dirty Context

If a conversation becomes noisy or the AI starts looping, issue the /clear command to start a fresh session and avoid wasted context.

Lock Down Permissions

Pre‑authorize safe commands in .claude/settings.json and add dangerous operations—such as reading .env, executing rm -rf, or force‑pushing code—to a deny list, preventing accidental destructive actions.

Package Repetitive Workflows with Skills

Create a SKILL.md file that runs lint, tests, and generates a commit message in one step. Then ask Claude to “prepare a commit” and it will execute the whole workflow automatically.

Claude Code is powerful, but it does not decide what should be done; you must still define boundaries, perform validation, and make final decisions, otherwise the tool may “fly full‑throttle” into a wall.
