TL;DR

A deep dive into 72 Claude Skills for business, covering planning, design, research, and operations. Includes custom workflow packs for meeting automation and invoice processing to maximize productivity.

“I can't finish reading the viral Skills articles from overseas because they're all in English.”

“I want to add Skills, but I end up leaving them alone because I don't know which ones to actually install.”

This is a common struggle. In a sea of information, it's hard to know what the right answer is.

Have you had these experiences while using Claude Code?

  • You see a viral article about Skills read by 4.2 million people, but you can't get through the English.
  • You bookmarked Skills-related posts but haven't actually set any up.
  • You feel anxious seeing others master AI while you're still giving instructions from scratch every time.
  • You have to explain the same things to the AI repeatedly because it forgets previous context.

For those people, I have organized 72 Skills used by top players into specific categories. I've also included some original Skills for your reference.

An article by AI Builder / CEO Mr. Buzzoni is currently going viral with 4.2 million views and 19,000 bookmarks.

Before we start, just two things:

  1. Save this article and set aside 20 minutes this week.
  2. Share this article with anyone else using Claude Code.

I will break down that content into easy-to-understand terms and explain it by directly reading the contents of the SKILL.md files.

The original post introduced 67 Skills. In this article, I have restructured them into 4 categories for the Japanese business scene, added 3 unique combination packs, and 2 practical skills, totaling 72 selections.

Skills are a "Mechanism to Remember Permanently Once Taught"

東大ClaudeCode研究所 - inline image

Normal AI chats reset everything once a session ends.

The "report format" or "presentation preferences" you taught last week are gone. That's why you have to redo the same explanations from scratch every time.

Skills are a mechanism that fundamentally solves this problem.

By defining "how to work" in a file called SKILL.md, Claude Code will permanently act according to those rules. Procedures, constraints, templates, and concrete examples—just write them all in one file.

Installation is just a one-line command.

bash
1claude install @anthropics/skills/pdf

By running this, you can use PDF reading, merging, and splitting anytime. I will explain the sources and the overall ecosystem in detail later. For now, let's find the Skills that suit your work from these four categories.

"Thinking": Planning and Brainstorming

東大ClaudeCode研究所 - inline image

"Thinking time" is the most valuable time in business.

However, many people lose time to "tasks" like formatting proposals, searching for past materials, or repeating drafts.

Let's compare a world with and without Skills.

Before: Spending 3 days writing a proposal alone with no one to bounce ideas off of.

After: Completing the outline in 30 minutes by brainstorming with AI, then focusing the rest of the time on judgment and decision-making.

■ Brainstorming (obra/superpowers)

Throw an idea at it, and the AI will finish a design document using a 9-step structured process. It asks what you want to create, suggests visual aids, asks questions, and presents multiple approaches. Once the design doc is done, the AI reviews it itself and asks for your review too.

東大ClaudeCode研究所 - inline image

The most important rule of this skill is "do not write any code until the design document is approved." A mechanism is built-in from the start to prevent moving to execution before thoughts are organized. The quality of planning and proposals improves through the "power of the process" rather than just individual "thinking power."

Honestly, this alone makes Skills worth installing.

https://github.com/obra/superpowers/tree/main/skills/brainstorming

■ Grill Me (mattpocock/skills)

This is my personal favorite.

When you give the AI a plan you think is "good enough," this skill will grill you with questions about every overlooked detail. It uses a question-interview format to resolve each branch of a decision tree, and even suggests recommended answers for each question. If you get stuck, the AI can even look up documents directly to skip questions.

The image is "getting grilled by AI before you get grilled by your boss." You can crush all the holes in your plan in advance.

https://github.com/mattpocock/skills/tree/main/grill-me

■ Write a PRD (mattpocock/skills)

This skill automatically creates a Product Requirements Document (PRD) from meetings or chat exchanges. Looking at the SKILL.md, it's designed to generate the PRD directly from the conversation context rather than re-interviewing. It outputs a structured proposal including problem definitions, solutions, feature lists, and out-of-scope items.

https://github.com/mattpocock/skills/tree/main/write-a-prd

■ PRD to Plan (obra/superpowers)

Automatically generates a detailed execution plan from a PRD. It breaks tasks down into 2-to-5-minute units and outputs a concrete plan including actual file paths and execution commands. The key is that it breaks down not just "what to do" but "where and how to start."

https://github.com/obra/superpowers

■ PRD to Issues (mattpocock/skills)

Automatically converts a PRD into task tickets. The SKILL.md uses the concept of "vertical slicing," where each task is divided so it can be completed from start to finish. Each task is categorized by whether it "requires human judgment" or "can proceed autonomously," making it easier to delegate to a team.

https://github.com/mattpocock/skills/tree/main/prd-to-issues

■ Design an Interface (mattpocock/skills)

The AI simultaneously generates three or more fundamentally different approaches for screen or system design. Based on the philosophy that "the first idea isn't always the best," you can compare designs with different constraints, such as focusing on simplicity, flexibility, or the most frequent use cases. This accelerates decision-making at the planning stage.

https://github.com/mattpocock/skills/tree/main/design-an-interface

■ Domain Name Brainstormer (skillsmp.com

Generates a large number of ideas for service and domain names. It can be used as a branding partner. It comes up with naming candidates from angles you might not think of, which is useful when starting new businesses or projects.

https://github.com/Microck/ordinary-claude-skills/tree/main/skills_all/domain-name-brainstormer

■ Idea Mining / YouTube (skillsmp.com

Automatically collects content ideas from YouTube. It analyzes popular videos from competitor channels or trends in specific themes to suggest content plans. It's useful not just for YouTube creators but also for video marketing research.

https://github.com/AgriciDaniel/claude-youtube

Once the planning is done, the next phase is "Making."

"Making": Design, Production, and Development

東大ClaudeCode研究所 - inline image

As the barrier to "being able to make things" lowers, the judgment of "what to make" becomes the differentiator.

This category is the largest among the 72. It covers everything from design, web, images, and video to code development.

Before: Outsourcing website design and waiting 2 weeks.

After: Giving verbal instructions to AI and completing production-quality design in 1 day.

■ Frontend Design (Anthropic Official)

Just by saying "I want a web page like this," a screen that looks like it was made by a professional appears. The design principles in SKILL.md explicitly state to "avoid generic AI-like designs." It generates UIs for dashboards and web apps at a level usable in production. Even without a designer, you can create and check prototypes yourself.

https://github.com/anthropics/skills/tree/main/skills/frontend-design

■ Canvas Design (Anthropic Official)

The interesting thing about this skill is that it doesn't start by drawing.

東大ClaudeCode研究所 - inline image

It starts by verbalizing a "Design Philosophy Manifesto." It's a two-step process: first defining "what you want to convey," then expressing it as a PNG or PDF visual. This prevents results that "look okay but don't convey anything." It's powerful for SNS materials, posters, and document illustrations.

Verbalization is very important when using AI. Even for the same purpose, the specificity of information, surrounding details, and background significantly affect quality.

https://github.com/anthropics/skills/tree/main/skills/canvas-design

■ Theme Factory (Anthropic Official)

The easiest way to solve the "I want my documents to look professional" problem. Choose from 10 preset themes or generate a custom one. Color palettes and font pairings are applied consistently across all pages. You don't have to worry about selecting colors or fonts anymore.

https://github.com/anthropics/skills/tree/main/skills/theme-factory

To put what you've made out into the world, there are processes for "Researching" and "Writing."

"Researching & Writing": Research and Documentation

東大ClaudeCode研究所 - inline image

"Researching and writing" is something almost every business person does daily. If this time were cut in half, the impact would be immeasurable.

Before: 1 day for research, 1 day for writing. Total 2 days.

After: AI organizes research and co-creates a draft. Finished in half a day.

■ Doc Co-Authoring (Anthropic Official)

A skill for writing proposals and plans together with AI. It includes a 3-step process: first, the AI collects information on what should be written; next, it creates drafts for each section; and finally, it starts a separate session to automatically check for unclear parts from a reader's perspective.

https://github.com/anthropics/skills/tree/main/skills/doc-coauthoring

東大ClaudeCode研究所 - inline image

This "reader test" is subtly amazing. The task of writing and proofreading alone changes to "co-creating with AI and AI performing the reader test."

■ Edit Article (mattpocock/skills)

A skill for "polishing" text. It's not just a grammar check. Reading the SKILL.md, it analyzes the entire article as an "information dependency graph." It organizes which information is needed before other information and restructures it into the most understandable order for the reader. It then rewrites each paragraph to be short and clear, with a rule of max 240 characters per paragraph. It's structural editing that sharpens the points.

https://github.com/mattpocock/skills/tree/main/edit-article

■ Content Researcher (skillsmp.com

When given a theme, this skill structures and organizes research results. It finds relevant sources, extracts key points, and outputs them categorized by theme. You can delegate the entire research process for proposals and plans.

https://github.com/ComposioHQ/awesome-claude-skills/blob/master/content-research-writer/SKILL.md

■ Obsidian Vault (mattpocock/skills)

A skill for accumulating and searching knowledge in coordination with Obsidian. The SKILL.md defines a flat structure where notes are linked using wikilinks and related topics are summarized in an Index Note.

Finally, Skills for automating repetitive daily tasks.

"Running": Operations and Documentation

東大ClaudeCode研究所 - inline image

Repetitive "tasks" performed monthly or weekly are where Skills have the greatest effect. By giving tasks to the AI as definitions, you can focus on "judgment."

Before: 15 hours of manual entry for 50 invoices, plus 3 hours for verification.

After: Put them in a folder and process everything in 15 minutes. Only manual check for calculation inconsistencies.

■ PPTX (Anthropic Official)

Instruct it to "make a presentation like this," and a PowerPoint file is automatically generated. It can also extract content as text from existing PPTX files, so it can be used for remaking past materials. After generation, you can check the actual slide images and adjust the results visually.

https://github.com/anthropics/skills/tree/main/skills/pptx

■ XLSX (Anthropic Official)

AI handles data organization, graph creation, and formula automation for Excel files.

東大ClaudeCode研究所 - inline image

Processing is completed with instructions like "summarize this column" or "create a graph from this data." Furthermore, it has a formula recalculation function, so it checks whether calculation results are correct using an automatic verification program.

https://github.com/anthropics/skills/tree/main/skills/xlsx

■ PDF (Anthropic Official)

Skills are Available in 4 Places

東大ClaudeCode研究所 - inline image

You don't just make Skills yourself; they are already being developed and published worldwide.

■ Anthropic Official (https://github.com/anthropics/skills

A repository with 121k stars, publishing basic skills for document generation and design. PDF, XLSX, and PPTX introduced in this article are all here.

■ Individual Developers

Matt Pocock's repository (https://github.com/mattpocock/skills) has 16.5k stars. It features skills directly linked to practical work like Grill Me and Edit Article.

obra/superpowers (https://github.com/obra/superpowers) is a huge collection with 166k stars, containing powerful skills like Brainstorming.

■ Corporate Entry

Major tech companies like Microsoft, Sentry, Cloudflare, and Trail of Bits are also entering Skills development. Skills made by companies are optimized for coordination with their products.

■ Marketplaces

Over 66k Skills are published on SkillsMP (https://skillsmp.com). Just search and install.

However, a word of caution: Skills are easy to distribute, and unofficial ones can be quickly published and installed via GitHub, so security risks must be considered. It's dangerous to install many obscure skills carelessly, so make it a habit to verify them before introduction.

5 Original Skills Released for Free

東大ClaudeCode研究所 - inline image

From here, I'll introduce skills that weren't in the original article. I'll introduce 2 uniquely prepared Skills and 3 workflow packs for different business patterns that combine multiple Skills.

■ Planning Brainstorming Pack

A workflow that completes everything from brainstorming to verification to proposal creation just by throwing in an idea. Use Brainstorming to structure the idea, Grill Me to crush holes in the plan, and Write a PRD to summarize it. By using these three skills in order, a proposal that used to take 3 days alone can be finished in half a day.

■ Document Bulk Processing Pack

A workflow that automatically reads and organizes the contents of a folder containing a mix of PDF, Word, and Excel files. Even if formats are inconsistent, just put them in one folder and instruct it to "read everything and summarize it in a comparison table."

■ Research → Writing Pack

A workflow that completes everything from investigation and structure to writing and proofreading just by throwing in a theme. Use Doc Co-Authoring for information gathering, draft creation, and reader testing, then use Edit Article to optimize the structure of the entire text.

Furthermore, we are releasing two skills we use in our actual work:

■ Meeting Automation (/mtg-notes)

A skill that completes minutes, TODOs, and the next agenda in 15 minutes just by providing a recording or text of a meeting. The feature is the low barrier to entry; it works with just text input, so you can try it today without an API contract.

■ Invoice Reader (/read-invoices)

A skill that completes structured CSVs and calculation verification reports in 15 minutes just by putting invoice PDFs in a folder. The most important part of this skill's design is that it "doesn't leave calculations to the AI." Calculation verification is strictly executed by an automatic verification program.

Introducing Skills Starts with Meta-Skills

東大ClaudeCode研究所 - inline image

With 72 options, it's easy to not know where to start. Begin with these three steps:

■ Install Meta-Skills

First, acquire the ability to "find and create Skills" itself.

  • Skill Creator — Anthropic's official skill creation tool.
  • Write a Skill — A skill that teaches how to write skills.
  • Find Skills — A skill for searching and discovering Skills that suit you.

■ Choose one skill that fits the task you spend the most time on

You don't need to install 10 at once. I recommend starting by making just one task you repeat daily into a Skill.

東大ClaudeCode研究所 - inline image

■ Use, Fix, and Grow

Skills aren't finished once you install them. You can freely edit the contents of SKILL.md. They are things you grow by adding rules or changing templates to suit your business. The more you use them, the more they are optimized for your work.

Summary

  • Skills are a "mechanism to remember permanently once taught." The era of explaining from scratch every time is over.
  • 72 selections, restructuring the original 67 for the Japanese business scene and adding 5 unique ones.
  • The ecosystem is growing to a scale of 1,116 skills, from Anthropic official to the community.
  • The essence of Skills is the mechanism of "passing tasks to AI as definitions." The source of differentiation lies in judgment and philosophy.
