What are Claude Code Skills?

Claude Code Skills are reusable prompt templates stored as markdown files in your project's .claude/skills/ directory. They let you codify best practices and common workflows into slash commands that Claude follows consistently.

How do I create a Claude Code Skill?

Create a markdown file in .claude/skills/ with instructions for Claude. The filename becomes the command name — for example, .claude/skills/code-review.md can be invoked with /code-review during a Claude Code session.

Can I share skills with my team?

Yes. Skills stored in .claude/skills/ can be committed to version control so every team member has access to the same standardized workflows. You can also organize skills into subdirectories by category.

What is the difference between project and global skills?

Project skills (.claude/skills/) are specific to the current project and are committed to git. Global skills (~/.claude/skills/) are personal skills available across all your projects.

ebay-listing

List items for sale on eBay. Supports fixed-price and auction listings with local image upload, product photo cleanup, and multiple marketplaces.

Dependencies

bash

pip install requests Pillow

Setup

Create an app at developer.ebay.com (free, no API fees)
Go to the User Tokens tab > Auth'n'Auth > Sign in to Production
Sign in with your eBay account to generate a token
Export it:

``bash export EBAY_AUTH_TOKEN=<your-token> ``

That's it. The token lasts ~18 months and the script uses eBay's Trading API (XML) with it.

Why Auth'n'Auth? The OAuth 2.0 alternative requires a browser-based redirect flow that's finicky on localhost. Auth'n'Auth is simpler for personal use — one token, no callback server. The script supports both methods and auto-detects based on which env vars are set.

Usage

code

> List my GoPro on eBay for $299, condition is like new
> Create a draft eBay listing for this camera with these photos
> Clean up my product photos in this folder

Direct script usage

bash

# Create a listing
python3 scripts/ebay_list.py list \
  --title "GoPro Hero 12 Black" \
  --description "Brand new, sealed in box." \
  --price 299.99 \
  --condition NEW \
  --image "https://example.com/photo.jpg" \
  --marketplace US \
  --currency USD

# Photo cleanup (auto white balance, contrast, sharpening)
python3 scripts/photo_cleanup.py <directory|file>

Listing options

Option	Required	Description
`--title`	Yes	Item title (max 80 chars)
`--description`	Yes	Item description (max 4000 chars)
`--price`	Yes	Listing price
`--condition`	Yes	NEW, LIKE_NEW, USED_EXCELLENT, USED_VERY_GOOD, USED_GOOD, FOR_PARTS_OR_NOT_WORKING, etc.
`--image`	Yes	HTTPS image URL (repeatable for multiple images)
`--category`	No	eBay category ID
`--marketplace`	No	US (default), UK, AU, CA, DE, FR, IT, ES
`--currency`	No	USD (default), GBP, AUD, CAD, EUR

Platform notes

•Free API access, no fees. Auth'n'Auth token lasts ~18 months.
•Supports fixed-price and auction listings.
•Includes photo_cleanup.py for auto white balance, contrast, brightness, and sharpening of product photos.
•Also supports OAuth 2.0 (Inventory API) if you set EBAY_CLIENT_ID, EBAY_CLIENT_SECRET, EBAY_RUNAME instead — auto-detects based on which env vars are present.

himalaya-email

Read, send, and manage email from Claude Code using the himalaya CLI. No scripts needed — this plugin teaches Claude how to use the himalaya commands directly.

Prerequisites

Install himalaya (v1.2.0+):

``bash brew install himalaya ``

Configure your email account in ~/.config/himalaya/config.toml (or ~/Library/Application Support/himalaya/config.toml on macOS). See the himalaya docs for config examples.

Features

•List and read emails from any folder (INBOX, Sent, Drafts, etc.)
•Send emails and reply to threads with proper threading headers
•Trace email origins — inspect SPF, DKIM, DMARC, and Received headers
•Preview mode (-p flag) to read without marking as seen
•Gmail folder alias support (Sent Mail, Drafts, Bin, Spam)
•JSON output for programmatic use

Usage

code

> Check my inbox
> Read the latest email from GitHub
> Reply to that email saying thanks
> Where did this email actually come from? Check the headers
> Show me emails in my Sent folder

Platform notes

•Works with any IMAP/SMTP email provider (Gmail, Outlook, Fastmail, etc.)
•Gmail users: set message.send.save-copy = false in config to avoid duplicate sent messages.
•No API keys needed — uses standard IMAP/SMTP with app passwords.
