Claude Code best practices

The habits that separate frustrating Claude Code sessions from great ones: specific prompts, CLAUDE.md project memory, plan mode, skills, and knowing when to clear context.

Claude Code's output quality tracks the quality of what you give it. The same model produces wildly different results depending on how you prompt, what project context you maintain, and how you manage a session. These are the practices that consistently pay off, distilled from Anthropic's own guidance and heavy daily use.

Be specific, and give the why

"Fix the bug" makes the agent guess. "Fix the login bug where users see a blank screen after entering wrong credentials" lets it go straight to work. Include the symptom, where it happens, and what correct behavior looks like. For features, say what the change is for; the agent makes dozens of small decisions on your behalf, and intent is what keeps them aligned.

Let it explore before it edits

For any non-trivial task, have Claude understand the code first:

analyze the database schema

how does authentication work in this codebase?

Then ask for the change. For bigger work, use plan mode (Shift+Tab cycles permission modes): the agent researches and presents a plan you approve before any file changes. Reviewing a plan is much cheaper than reviewing a wrong diff.

Maintain a CLAUDE.md

CLAUDE.md at the repo root is loaded into every session: build commands, conventions, gotchas, what not to touch. Run /init to generate one, then prune it. Keep it short and current; a stale CLAUDE.md actively misleads the agent. Things that belong there: the test command, the package manager, naming conventions, and any rule you find yourself repeating.

Break big tasks into steps

A numbered list beats a paragraph of wishes:

1. create a new database table for user profiles
2. create an API endpoint to get and update user profiles
3. build a page where users edit their information

The agent works through steps in order and you can correct course between them.

Manage your context

  • /clear between unrelated tasks. Leftover context from the last task pollutes the next one.
  • claude -c continues the most recent conversation when you genuinely want the history.
  • Long sessions degrade; if the agent starts forgetting earlier decisions, summarize the state into a message (or CLAUDE.md) and start fresh.

Give it a feedback loop

Claude Code iterates well when it can check its own work. Make sure tests run (bun test, npm test, whatever applies) and tell it to run them. "Write the function, then run the tests and fix failures" routinely one-shots tasks that "write the function" does not.

Use skills for repeatable workflows

Skills are reusable instruction packages the agent loads on demand: deployment runbooks, code review checklists, document generators. If you find yourself pasting the same instructions twice, make it a skill. Browse skills for Claude Code to start from existing ones, including Anthropic's official set.

Quick wins

  • Type / to discover commands and installed skills.
  • Shift+Tab cycles permission modes; "accept edits" mode removes per-edit confirmation on trusted work.
  • Press ↑ for prompt history, Esc to interrupt a runaway response.
  • Ask Claude about itself: "what can Claude Code do?" is a real query that works.
