Comparison
Loreto skills vs a prompt library
A prompt library is a collection of text prompts you copy-paste. A Loreto skill is an installed, structured workflow your agent invokes on its own — with references and a test — and can run as a CLI or MCP.
Quick answer
Loreto skills: A Loreto skill is a packaged workflow (SKILL.md + references + test) the agent loads and runs when relevant. A prompt library: A prompt library is a catalog of reusable prompt text you paste into a chat.
| Loreto skills | A prompt library | |
|---|---|---|
| Form | Installed, invocable workflow | Copy-paste text |
| Runs by | The agent, automatically | You, manually |
| Carries references & test | Yes | No |
| Runs as CLI / MCP | Yes | No |
| Distribution | Marketplace, ratings, pricing | A doc or repo |
Use Loreto skills when

Use A prompt library when
- You just want a few prompts to paste occasionally
