5 Claude Code Skills to Automate Your Development Workflow

Skills are not “smart macros” but context‑aware automation

Traditional macros or shell scripts repeat fixed steps, while Claude Code Skills understand the project context and decide actions automatically.

1. pr-summary – auto‑generate Pull Request description

Each PR description normally requires manual wording; this Skill fetches live PR data via GitHub CLI (diff, comments, changed files) and generates a reliable summary based on the actual code diff.

# SKILL.md 示例
---
name: pr-summary
description: 总结 Pull Request 的变更内容
context: fork
allowed-tools:
- Bash(gh *)
---

## Pull request context

- PR diff: !`gh pr diff`
- PR comments: !`gh pr view --comments`
- Changed files: !`gh pr diff --name-only`

## 任务

请总结这个 Pull Request。请包含变更目的、影响范围，以及审阅者需要特别注意的点。

Typical scenarios:

Daily PR creation – almost no manual description needed.

Large‑scale refactoring – automatically summarise overall changes.

Onboarding new members – the Skill itself serves as a PR‑writing example.

The Skill uses the ! syntax to run shell commands and bases the summary on real diffs, making it more reliable.

2. fix-issue – from issue number to fix and PR

This Skill compresses the whole workflow of opening an Issue, locating the relevant code, fixing it, testing, and submitting a PR into a single command.

---
name: fix-issue
description: 修复指定的 GitHub Issue
disable-model-invocation: true
---

请修复 GitHub Issue $ARGUMENTS。

1. 使用 gh 命令获取 Issue 内容
2. 找到相关代码
3. 实现修复
4. 运行测试并确认通过
5. 提交变更

Invocation example: /fix-issue 1234. The $ARGUMENTS placeholder is replaced with the Issue number.

Automation flow:

/fix-issue 1234
↓
Claude 使用 gh 命令获取 Issue #1234 的内容
↓
定位相关文件并修改
↓
执行测试确认没问题
↓
完成提交

The author reports that time spent on small but necessary bugs is roughly halved after using this Skill.

3. deep-research – exhaustive code‑base investigation

This Skill creates a sub‑agent (context: fork) that can thoroughly explore a repository without polluting the current conversation, making it ideal for deep debugging or design understanding.

---
name: deep-research
description: 针对某个主题进行彻底调查
context: fork
agent: Explore
---

请围绕 $ARGUMENTS 进行彻底调查：
1. 找出所有相关文件
2. 追踪依赖关系和数据流
3. 列出潜在问题和改进空间
4. 写一份调查结果报告

Typical commands: /deep-research 支付流程中发生超时的原因 – fault investigation. /deep-research 认证模块的架构 – understand design. /deep-research 所有使用废弃 API 的地方 – audit technical debt.

Especially useful before taking over a large legacy project or planning a major refactor.

4. commit – stage and commit without confirmation

This Skill automates the entire git workflow (add, commit, status) by declaring the required tools in allowed-tools. It also generates Conventional Commits‑style messages.

---
name: commit
description: 对当前变更进行暂存并提交
disable-model-invocation: true
allowed-tools:
- Bash(git add *)
- Bash(git commit *)
- Bash(git status *)
---

请对当前变更执行以下操作：
1. 将变更加入暂存区（stage）
2. 生成一个描述变更内容的提交信息并提交
3. 提交信息需遵循 Conventional Commits 格式（如 feat/fix/refactor/docs 等）

Generated commit message example:

# Claude 生成的 commit message 示例

feat(auth): 使JWT令牌的过期时间可配置化
- 修改为可通过环境变量 JWT_EXPIRES_IN 来设置过期时间
- 设置默认值为24小时
- 添加测试用例

The Skill chooses appropriate prefixes such as feat or fix based on the code changes, helping the team follow commit conventions automatically.

5. explain-code – produce documented, visual explanations

This Skill turns a request like “explain this code” into a structured document that includes a one‑sentence summary, a Mermaid flowchart, everyday analogies, and suggested improvements.

---
name: explain-code
description: 结合可视化图解和类比来解释代码
---

请按以下结构说明指定的代码：
1. 用一句话概括这段代码做了什么
2. 使用 Mermaid 语法画出处理流程图
3. 用生活化的类比解释复杂部分
4. 指出潜在的改进点

Useful scenarios:

Preparing PR documentation – automatically attach a diagram‑rich explanation.

Onboarding or knowledge transfer – generate one‑click explanations of complex modules.

Documenting legacy code without comments – systematically produce documentation.

The Skill focuses on making the code understandable to the team, which can dramatically lower long‑term documentation maintenance costs.

5 Skills Quick Reference

pr-summary – generate PR description – /pr-summary fix-issue – issue → fix → PR – /fix-issue 1234 deep-research – deep code‑base investigation – /deep-research … commit – stage and commit – /commit explain-code – generate visual code explanation –

/explain-code

Tips for Introducing Skills to a Team

Place Skill files under .claude/skills/ and manage them with Git so every team member shares the same automation rules.
