Claude Code Skills Marketplace (daymade/claude-code-skills)

What it is – A curated collection of production‑ready Claude Code plugins (called skills) that extend the Anthropic Claude Code environment with ready‑made workflows. The repo ships a meta‑skill called skill‑creator that helps you build, validate, and package your own Claude Code skills, plus dozens of ready‑made skill suites for docs, macOS/iOS development, financial data, Codex integration, and general productivity.

Key components

• skill‑creator – a hardened fork of Anthropic’s official skill‑creator. It adds structured decision‑matrices, security scans, concurrency guards, evidence‑based validation, and packaging helpers.
• Skill suites – groups of related plugins under a shared namespace (e.g. daymade-docs, daymade-macos, daymade-codex, daymade‑claude‑code, daymade‑financial). Installing a suite pulls in all its members.
• Standalone skills – individual plugins for GitHub ops, AI‑icon lookup, YouTube download, cloudflare diagnostics, etc.
• Installation helpers – shell scripts (install.sh, install.ps1) and in‑app /plugin commands for quick setup.

How to install

1. In‑app (Claude Code UI):

   /plugin marketplace add daymade/claude-code-skills
   

   Then browse the marketplace and click Install on the desired skill or suite.
2. CLI (any terminal with the Claude Code CLI):

   claude plugin marketplace add https://github.com/daymade/claude-code-skills
   # marketplace name is daymade-skills
   claude plugin install daymade-skill@daymade-skills   # installs skill‑creator
   

3. Automated script (macOS/Linux):

   curl -fsSL https://raw.githubusercontent.com/daymade/claude-code-skills/main/scripts/install.sh | bash
   

   (Windows PowerShell equivalent is provided.)

Typical workflow with skill‑creator

Claude, "Create a new skill called my-awesome-skill in ~/my-skills"
Claude, "Validate my skill at ~/my-skills/my-awesome-skill"
Claude, "Package my skill at ~/my-skills/my-awesome-skill for distribution"

The meta‑skill guides you through requirement gathering, structural checks, security scanning, and final packaging.

Sample use‑cases

• Documentation automation – convert Word/PDF/Confluence docs to markdown, extract Mermaid diagrams, generate PDFs or PPTX.
• Mac/iOS dev ops – screen capture, permission handling, watchdog utilities for macOS.
• Financial research – pull structured data from RavenPack, yfinance, and Chinese market APIs; run adversarial due‑diligence checks.
• GitHub management – create PRs, manage issues, automate Actions, enforce 2FA policies.
• Claude Code power‑user tweaks – custom statuslines, usage analytics, session recovery, multi‑model switching.

Documentation & demos

• Full skill‑creator guide: daymade-skill/skill-creator/SKILL.md
• Methodology doc: skill-creator/references/skill-development-methodology.md
