What Is OPC Skills?

OPC Skills (Open Plugin Collection) is an open-source skill pack published by ReScienceLab that adds domain-specific automation capabilities to AI coding agents. The project launched on Show HN in August 2026.

Each skill is a self-contained folder with a SKILL.md file containing instructions, scripts, and metadata. Skills are loaded dynamically by compatible AI agents at runtime. The project follows the agentskills.io standard.

Included skills:

| | Skill | Description | |:---:|-------|-------------| | | seo-geo | SEO and GEO optimization for AI search engines (ChatGPT, Perplexity, Google) | | | requesthunt | Research user demand from Reddit, X, and GitHub | | | domain-hunter | Find domains, compare registrar prices, and discover promo codes | | | logo-creator | Create logos with AI, crop, remove background, export as SVG | | | banner-creator | Create banners for GitHub, Twitter, LinkedIn | | | nanobanana | Generate images using Gemini 3 Pro Image | | | reddit | Search and retrieve content from Reddit via the public JSON API | | | twitter | Search and retrieve content from Twitter/X via twitterapi.io | | | producthunt | Search Product Hunt posts, topics, users, and collections | | | archive | Archive session learnings and debugging solutions with indexed markdown |

Some skills depend on others: domain-hunter requires twitter and reddit; logo-creator and banner-creator both require nanobanana.

Supported AI tools (16+): Claude Code, Cursor, Windsurf, Droid, and 12+ others via the universal npx skills add command.

Setup Workflow

Prerequisites

• Node.js 18+ installed
• An AI coding tool with skill loading support (Claude Code, Cursor, or similar)

Step 1: Install the Skill Marketplace (Claude Code)

If you use Claude Code, add the OPC Skills marketplace first:

/plugin marketplace add ReScienceLab/opc-skills

Step 2: Install Individual Skills

# Install specific skills
/plugin install requesthunt@opc-skills
/plugin install domain-hunter@opc-skills
/plugin install seo-geo@opc-skills

# List all available skills
/plugin marketplace list opc-skills

Step 3: Universal Installation (any AI tool)

For Cursor, Windsurf, Droid, or any other compatible tool, use the universal installer:

# Install all skills
npx skills add ReScienceLab/opc-skills

# Install a specific skill
npx skills add ReScienceLab/opc-skills --skill reddit

# Install to a specific agent
npx skills add ReScienceLab/opc-skills -a droid

Step 4: Browse Available Skills

Discover and preview all skills at skills.sh/ReScienceLab/opc-skills.

How Skills Work

When loaded by a compatible AI agent, a skill’s SKILL.md file is injected into the agent’s context at the start of a relevant task. The skill file contains:

• Instructions — what the skill does and when to activate it
• Scripts — executable scripts the agent can call
• Resources — supporting files, templates, or data

For example, activating the requesthunt skill before a research task gives the agent a structured way to query Reddit and GitHub for user demand signals, without needing to figure out API calls or search syntax from scratch.

Practical Evaluation Checklist

• [ ] Claude Code or compatible agent installed
• [ ] Successfully added marketplace: /plugin marketplace list opc-skills returns skills
• [ ] Installed at least one skill: /plugin install requesthunt@opc-skills
• [ ] Tested a skill in context (e.g. asked agent to research demand for a product idea)
• [ ] Universal install worked on secondary AI tool (Cursor/Windsurf)
• [ ] Skill dependencies resolved (domain-hunter needs twitter + reddit)

Security Notes

• Skills load instructions into the AI agent’s context — review the SKILL.md content before activating skills that run external API calls
• The twitter skill uses twitterapi.io — you need an API key from that service
• Skills do not automatically execute code; the agent decides when and how to use them within your project directory

FAQ

Q: Does OPC Skills work with both free and paid tiers of Claude Code? A: The marketplace install requires Claude Code’s plugin system. The universal npx skills add approach works with any tool that implements the agentskills.io standard.

Q: How is this different from adding a custom instruction to my agent? A: Each skill is self-contained and versioned. You can install and remove specific skills without modifying your agent’s base configuration. Skills also include executable scripts and resource files that go beyond text instructions.

Q: Can I create and publish my own skills? A: Yes. Follow the agentskills.io standard — create a repository with a SKILL.md file and a clear metadata section, then publish to skills.sh or submit to the OPC Skills marketplace.

Q: Are these skills actively maintained? A: The repo received a commit on 2026-08-06 (default branch main). Check the issues page for recent activity.

Conclusion

OPC Skills fills a gap that anyone doing real product work with AI agents has felt: the base agent is great at writing code, but lacks structured pathways for tasks like demand research, domain selection, or social media asset creation. By packaging these workflows as drop-in skills, the project makes it practical to activate specialized behavior only when needed — without bloating the agent’s default context.

If you run a solo operation and use Claude Code, Cursor, or Windsurf daily, OPC Skills is worth a look. The install is one command, the skills are clearly documented, and they cover real solopreneur workflows — not toy examples.
