请先阅读项目结构，不要修改代码，先给我一个修改计划。

/diff
/code-review

/context
/compact

cd /path/to/project
claude

/init

请阅读项目结构，整理项目技术栈、启动命令、测试命令和核心模块说明。

请先分析这个需求，不要修改代码。请给出修改计划、影响范围和需要验证的测试点。

按这个计划修改代码，保持改动范围尽量小。

/diff

/code-review

请运行相关测试，并解释测试结果。

请根据当前 git diff 生成一条清晰的 commit message。

# Project Guide for Claude Code

## Project Overview

This is a Go backend project using Gin.

## Common Commands

- Run tests: `go test ./...`
- Start server: `go run ./cmd/server`
- Run lint: `golangci-lint run`

## Coding Style

- Prefer table-driven tests.
- Keep changes minimal and focused.
- Do not introduce large dependencies without confirmation.
- Use explicit error handling.

## Security Notes

- Do not print passwords, tokens, secrets, or credentials in logs.
- Validate file upload size, extension, content type, and storage path.
- Avoid path traversal and command injection risks.

# Go Test Writer

When writing Go unit tests:

1. Read the target function and related dependencies.
2. Identify input, output, errors, and side effects.
3. Prefer table-driven tests.
4. Avoid monkey patching unless explicitly requested.
5. Prefer dependency injection through interfaces.
6. Cover normal cases, error cases, nil cases, empty values, and boundary values.
7. Use clear test case names.
8. Use `t.Run` for each case.
9. Run the most relevant `go test` command if possible.

Before editing:

- List the test scenarios.
- Identify hard-to-test dependencies.

After editing:

- Summarize added test cases.
- Mention whether tests were run.
- If tests fail, explain the failure.

# Personal Preferences

- Use Chinese for explanations unless I ask for English.
- For Go unit tests, prefer table-driven tests.
- Avoid monkey patching unless there is no better option.
- Before large changes, explain the plan first.
- Keep changes minimal and focused.
- After code changes, run relevant tests if possible.
- Pay attention to security issues, especially sensitive logs, path traversal, file upload validation, command injection, and hardcoded credentials.
