Claude Code Tips: A Faster Workflow From Bug to Commit

The most useful Claude Code tips help you control the work: give the assistant a clear target, inspect its plan, and verify the result. Here is a practical workflow for fixing a bug in an existing repository, with shortcuts that reduce typing, wasted context, and unnecessary API spending.

1. Start inside the repository and configure access

Open a terminal at your project root and run claude. Starting in the correct directory gives Claude Code the right working context and makes relative file references predictable.

If you use 59API, configure Claude Code's Anthropic-compatible connection before launching it. In a macOS or Linux shell, set export ANTHROPIC_BASE_URL="https://api.59api.com" and export ANTHROPIC_AUTH_TOKEN="YOUR_59API_KEY", replacing the placeholder with your key. Use the model identifier provided by 59API; display names and API identifiers can differ.

59API offers low-cost, pay-as-you-go access to native official-quality models without model downgrades. For Claude Code work, Claude Sonnet 5.5 and Claude Opus 5.5 are two available examples. Match the model to the task, then check actual usage instead of assuming every request needs the most expensive option.

2. Save project rules with /init

Run /init to generate a starting CLAUDE.md file, then review it. Keep instructions concrete: the package manager, test commands, formatting rules, and directories that contain generated code. Confirm that suggested commands actually exist in your repository.

For example, record that this project uses pnpm, that focused tests run through a particular package script, and that database migrations require separate review. These instructions reduce repeated explanations across sessions. Keep them short enough that important rules remain easy to find.

3. Attach files and plan before editing

Suppose a checkout endpoint occasionally creates duplicate orders. Start with a bounded request: “Investigate duplicate order creation. Read @src/api/checkout.ts and its tests. Explain the likely cause and propose the smallest fix before changing files.” Substitute paths from your repository; typing @ helps you reference files directly.

Use Shift+Tab to cycle permission modes until Plan Mode is active. This lets you investigate and discuss an approach before implementation. Ask Claude to identify the failing behavior, affected callers, and a test that would demonstrate the bug.

After reviewing the plan, switch to your preferred editing permission mode and authorize that specific scope. A narrow task is easier to verify than an open-ended instruction to improve the entire checkout system.

4. Interrupt drift and recover quickly

Press Esc if Claude starts pursuing the wrong explanation or expanding the task. Follow with a specific correction: “Keep the public response format unchanged; focus on duplicate request handling.” Interrupting early usually saves more time than reviewing a large, unwanted patch.

Press Esc twice to open the rewind interface when you need to revisit an earlier checkpoint. Review the available conversation and code restore choices carefully. Checkpoints do not undo every external effect: database writes, deployed changes, and other side effects require separate handling.

5. Manage context before it becomes expensive

Use /context to inspect context usage. When a long investigation contains useful conclusions but lots of obsolete output, run /compact Preserve the root cause, changed files, and remaining test failures. This gives the summary a clear purpose.

Use /clear when moving to an unrelated task. Before clearing, save any decisions that should persist in project documentation. To pick up recent work later, launch claude --continue; use claude --resume to select a previous session.

6. Verify the patch and watch spending

Ask Claude to run the focused regression test first, followed by the relevant broader checks. Then request a review of the diff for accidental formatting changes, altered interfaces, and missing edge cases. Read the diff yourself before committing.

• /cost: inspect session usage and available cost information; reconcile relay charges against the 59API dashboard.
• /model: inspect or change the active model where supported by your configuration.
• /help: check commands and keyboard shortcuts available in your installed version.

For developers using several coding tools, 59API also supports Codex, Gemini CLI, and OpenAI SDK integrations, making API access easier to manage across workflows. Sign up for 59API to try this workflow with pay-as-you-go pricing; its referral rebate offers another way to offset usage costs.
