Top 10 Claude Cowork Skills from the Community (2026)

One of the best features of Cowork is the Skills system—the ability to save and share reusable workflows. The community has been hard at work building incredible tools.

Here are the top 10 Skills you should install today (sourced from awesome-claude-skills):

The "Must-Haves"

1. The Data Janitor

What it does: Point it at a messy Excel or CSV file. It automatically detects formatting errors, duplicates, and missing values—and fixes them. Why you need it: Saves hours of manual data cleaning. When to use it: Monthly reporting, CRM exports, survey results, or any time you receive a spreadsheet from a third party that needs to be normalized before analysis. Example prompt:

Clean the file sales-export-q1.csv in this folder. Remove exact duplicate rows, standardize date columns to ISO 8601, fill missing phone numbers with "N/A", and save the result as sales-export-q1-clean.csv. Write a short summary of what you changed.

2. Meeting to PRD

What it does: Takes a raw transcript (from Zoom/Teams). Outputs a fully formatted Product Requirements Document (PRD) with user stories and acceptance criteria. Why you need it: Turns talk into action items instantly. When to use it: After any planning meeting, customer interview, or design review where decisions were made but no one took structured notes. Example prompt:

Read the transcript file meeting-2026-03-12.txt. Produce a PRD in Markdown with these sections: Background, Goals, Non-Goals, User Stories (Gherkin format), Acceptance Criteria, and Open Questions. Do not invent decisions that were not stated in the transcript.

3. The Receipt Scanner

What it does: Reads a folder full of receipt images (JPG/PNG). Outputs a structured Expense Report (.xlsx) with categories and totals. Why you need it: Expense reports are the worst. Let AI do them. When to use it: End of month, end of quarter, or any time you need to submit reimbursable expenses to accounting. Example prompt:

Look at every image in the receipts/ folder. For each receipt, extract vendor, date, total amount, and currency. Categorize each as Travel, Meals, Office, or Other. Create Expenses-2026-03.xlsx with one row per receipt and a totals row at the bottom.

4. The Scholar

What it does: Connects to ArXiv and Google Scholar (via MCP). Finds relevant papers, downloads PDFs, and generates a summarized reading list. Why you need it: Essential for researchers and students. When to use it: Starting a literature review, preparing for a thesis proposal, or trying to get up to speed on a new subfield. Example prompt:

Search for papers published in 2025 and 2026 on "retrieval-augmented generation evaluation". Download the top 10 PDFs into this folder. Write reading-list.md with a one-paragraph summary of each paper, the key contribution, and a relevance score from 1 to 5.

5. The Code Reviewer

What it does: A strict, security-focused review bot. Checks for OWASP vulnerabilities and performance bottlenecks before you merge. Why you need it: It's like having a senior engineer on call 24/7. When to use it: Before opening a pull request, during a pre-merge gate, or when inheriting an unfamiliar codebase. Example prompt:

Review every changed file in this branch compared to main. Flag any OWASP Top 10 risks, hardcoded secrets, SQL injection, and obvious N+1 query patterns. Output review.md with file name, line range, severity (High/Medium/Low), and a suggested fix for each finding.

The "Quality of Life" Upgrades

6. Tweet Threader

What it does: Reads your blog post or article. Generates a viral-style Twitter/X thread (10-15 tweets) with hooks and hashtags. When to use it: After publishing a long-form post and wanting to promote it without spending an hour rewriting it for social. Example prompt:

Read the article launch-post.md. Write a 12-tweet thread. The first tweet is the hook and must be under 200 characters. Each tweet ends with a line break. Add 3 relevant hashtags on the final tweet only. Do not use clickbait phrasing.

7. Linear Sync

What it does: Reads a simple todo.md markdown file. Bi-directionally syncs it with your Linear issue tracker. When to use it: When you prefer drafting tasks in a local markdown file during focused work but need them visible to your team in Linear. Example prompt:

Read todo.md in this folder. For every unchecked item, create a Linear issue in the "Backlog" project with the label "cowork-sync". For every checked item, mark the matching Linear issue as Done. Append the Linear issue ID next to each item in todo.md.

8. Resume Tailor

What it does: Reads your master CV and a specific Job Description. Rewrites your CV to highlight the most relevant experience for that specific role. When to use it: When applying to a role you genuinely want and you have 15 minutes to make your CV match the job description closely. Example prompt:

Read master-cv.pdf and job-description.txt. Produce tailored-cv.docx that reorders my experience to put the most relevant roles first, mirrors the keywords used in the job description, and keeps all facts accurate. Do not invent experience I do not have.

9. Slide Deck Builder

What it does: Takes a text outline. Generates a Python script that builds a branded PowerPoint (.pptx) file automatically. When to use it: When you have the content ready but dread the manual click-work of assembling slides. Example prompt:

Read outline.md. Generate build_slides.py that uses python-pptx to create deck.pptx with my brand colors (primary #1F2937, accent #3B82F6). One slide per top-level heading, bullet points from sub-items, and a closing slide with a summary. Run the script and save deck.pptx in this folder.

10. Daily Briefing

What it does: The ultimate morning assistant. Scans your RSS feeds, Calendar, and flagged Emails to generate a "What you need to know today" summary. When to use it: First thing in the morning, before you open any other app, to decide where to focus your attention. Example prompt:

Pull today's calendar events, unread flagged emails, and the latest 20 items from my RSS OPML file. Write briefing.md with three sections: Meetings (time, attendees, prep needed), Emails (sender, subject, one-line why it matters), and News (headline, one-line summary). Keep the whole file under 400 words.

How to Install These Skills

Skills in Claude Cowork are distributed as plain markdown instruction files that the agent loads on demand. The install process is intentionally low-tech.

Find the Skill file. Community Skills are shared as .md files containing a system prompt, tool list, and usage rules. Download the file to a local folder you control, for example ~/ClaudeSkills/.

Reference it in your prompt. When starting a Cowork session, point Claude at the Skill file directly:

Use the instructions in ~/ClaudeSkills/data-janitor.md for the following task: clean sales-export-q1.csv.

Or load it via a project file. If you run Cowork inside a project directory, drop the Skill file into a .cowork/skills/ subfolder. Claude will detect files in that folder at session start and treat them as available tools.
Verify it loaded. Ask Claude, "Which Skills are available in this session?" It will list the detected Skill files and confirm each one parsed correctly.
Update by replacing the file. Skills are stateless text files. To upgrade, overwrite the .md file with the new version and restart the session.

There is no package manager, no registry, and no install script. This keeps Skills auditable: you can read every instruction Claude will follow before you run it.

Creating Your Own Skill

Building a Skill is mostly a writing exercise. You are writing instructions for a capable but literal agent. Here are the basic steps.

Name the Skill and define its scope. A good Skill name is a noun phrase: "Receipt Scanner", "Code Reviewer". The scope should be one job, not several. Skills that try to do three things usually do all of them poorly.

Write the instruction file. Start with a one-line purpose, then list the inputs the Skill expects, the steps it should follow, and the output format. Be explicit about what the Skill must not do. For example:

# Receipt Scanner
Purpose: Extract structured data from receipt images and produce an .xlsx report.
Inputs: A folder of receipt images (JPG, PNG, HEIC).
Steps:
  1. List every image in the input folder.
  2. For each image, extract vendor, date, total amount, and currency.
  3. Categorize each receipt as Travel, Meals, Office, or Other.
  4. Write one row per receipt to Expenses.xlsx.
  5. Add a totals row at the bottom.
Constraints:
  - Do not invent fields that are not visible on the receipt.
  - If a field is unreadable, write "unclear" rather than guessing.
Output: Expenses.xlsx in the same folder, plus a summary of receipts processed.

Test on a small batch. Run the Skill on 3 to 5 example inputs before trusting it on a full folder. Check the output by hand the first time.
Iterate on the instructions. If Claude misreads a receipt, the fix is usually in the instruction file, not the prompt. Add a rule like "If the vendor name is ambiguous, use the most prominent text on the receipt."
Share it. Once the Skill is stable, share the .md file with colleagues or post it to a community collection. Because Skills are plain text, they diff cleanly in version control.

Why These Skills Made the List

The ten Skills above were selected using four criteria.

Real adoption. Each Skill appears in multiple community collections and has been referenced in public Cowork usage reports. Skills that only exist in a single repo, with no evidence of anyone running them, were excluded.
Clear input and output. A useful Skill names its inputs (a folder, a file, a transcript) and produces a concrete artifact (a spreadsheet, a markdown file, a Python script). Skills that output only "a response" are harder to verify and were deprioritized.
Low hallucination risk. Skills that require Claude to invent facts, write legal language, or make financial decisions were excluded. The best Skills constrain Claude to extraction, formatting, and transformation, where accuracy is checkable.
Composable with other Skills. Several of these Skills feed into each other. The Scholar produces a reading list that the Daily Briefing can summarize. Meeting to PRD produces a document that Linear Sync can track. Skills that fit into a workflow ranked higher than standalone utilities.

If you are evaluating a Skill not on this list, apply the same four criteria. A Skill that scores well on all four is likely worth installing.

Where to Find More

Look for community-maintained Claude Skills collections from ComposioHQ and karanb192 if you want more examples. CoworkHow no longer publishes GitHub repository links from this site.
