Claude Code Setup: from environment preparation to first commit
Claude Code 设置不是装完就结束
The useful part of Claude Code Tutorial #1 - Introduction & Setup is not every individual click in the recording. The durable lesson is when to use Claude Code, how to bound the task, and how to verify the result. This article turns the topic into an executable guide rather than a recap.
The core principle is simple: make the workflow verifiable before making it more autonomous. A long AI-generated answer that cannot be checked creates review debt. A modest intermediate artifact that can be inspected can grow into a reliable system.
项目记忆应该写什么
This pattern fits three kinds of work. The first is work with clear input and a stable output format, such as classifying feedback, editing one component, or creating a migration checklist. The second is tool-assisted work, such as reading files, searching, writing to a CMS, or running tests. The third is collaborative work, where AI prepares a draft and a human approves the next action.
Avoid high-risk automation at the beginning. Deleting data, sending formal messages, changing permissions, creating orders, or making payments should stay behind approval. Boundaries are part of the design, not an afterthought.
第一次任务如何选
- Start with repository entry points, configuration, and related modules
- Describe user-visible behavior and the files or areas that must not change
- Ask for a file-level plan before editing
- Run the verification that matches the risk after each change
- End with changed files, checks, and remaining risks
You do not need to automate everything at once. Run one small task, save the successful structure, and reuse the structure next time. The reusable asset is the workflow shape, not a magic prompt.

For Claude Code Tutorial #1 - Introduction & Setup, a practical loop is: define the goal, gather inputs, restrict tools, and design acceptance checks. If you are assigning a development task, do not write “build this feature.” Write: inspect these files, explain current behavior, change only the target component, run the relevant check, and list remaining risks.
Every stage leaves something observable. Current-behavior analysis shows whether context was understood. A file plan shows whether scope is too broad. A check command catches concrete failures. A risk list tells the human where judgment is still required.

The common failure modes are:
- Starting with a large implementation request and losing scope
- Failing to protect existing user changes
- Running only compilation while missing UI regressions
The fix is usually smaller scope, narrower permissions, and more intermediate checkpoints. Do not use a stronger model as a substitute for workflow design. Stronger models still need boundaries; otherwise they can move confidently in the wrong direction.
常见设置问题
Try a thirty-minute exercise. Pick one real but low-risk task and write a task card with goal, input, allowed tools, forbidden actions, and acceptance criteria. Save the plan, tool results, final artifact, and failure notes.
Afterward, ask three questions: which step was easiest for AI to misunderstand, which step was hardest to verify, and which step should become a reusable template. Those answers tell you whether to improve the prompt, tool description, or acceptance rule.
常见设置问题 acceptance checklist
- Can the task be described in one sentence?
- Is the input material complete enough?
- Are missing facts listed instead of guessed?
- Are tool permissions minimal?
- Does every step leave an inspectable artifact?
- Is there a clear recovery point after failure?
- Can a human review the final output quickly?

Implementation details for 权限和命令要提前约束
Claude Code can work across a repository, which makes boundaries more important. A high-quality request names the problem, visible behavior, allowed directories, forbidden files, verification commands, and expected handoff format. Asking it to inspect before editing reduces unrelated changes.
For team use, require every AI-assisted diff to explain why the change was made, which files changed, and how it was verified. Review then focuses on diff, checks, and risk rather than guessing the model intent.
Reviewing 从第一轮提交建立习惯
Do not only ask whether the result is usable. Record whether the input was complete, whether each tool call was necessary, whether failures were recoverable, and how long human review took. Those notes become the improvement path for the next run.
If the same failure appears twice, update the task template, tool description, or verification script instead of relying on memory. That is more stable than switching models reactively.
Operating playbook for Claude Code 设置
Turn 第一轮提交 into a playbook rather than an improvised chat. Write the goal, inputs, allowed tools, forbidden actions, and acceptance checks before execution. During execution, inspect whether the model understood the input, stayed inside boundaries, and can explain each step. If a step cannot be explained, revise the playbook instead of asking for more prose.
The key is making the assistant understand the system before editing. Limit each run to one visible behavior and require verification commands plus remaining risks. Then Claude Code behaves more like a pair engineer than a black box.
Decision table for 项目记忆
Create a three-column table: condition, action, verification. If information is missing, the action is to list missing fields. If production data would change, the action is human approval. If a test fails, preserve the error and return to the previous step. The table turns tacit judgment into explicit rules.
Reusing 第一轮提交
After the first successful run, save the original input, playbook, intermediate artifacts, verification result, and failure notes. The next similar task should start from this record. For teams, add owner and risk level fields so everyone knows who approves risky actions and which tasks remain semi-automated.
