SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Skyll enables agents to dynamically discover and retrieve skills at runtime. Instead of having all skills pre-loaded, agents can search for relevant skills on-demand and inject them into context.

Core Features & Use Cases

  • On-demand skill discovery from multiple sources (skills.sh, GitHub, and community registries)
  • Full SKILL.md retrieval for context injection
  • Optional references and metadata extraction for richer tooling
  • Use Case: An agent needs a specialized capability; fetch and inject the matching SKILL.md into its context for execution.

Quick Start

Search for skills relevant to the current task and inject the full SKILL.md content into the agent's context.

FAQPage Schema
How do I dynamically discover and retrieve agent skills at runtime?

Dynamically discover agent skills at runtime by searching multiple sources like skills.sh and GitHub on-demand. This fetches the full SKILL.md content for relevant skills and injects it directly into the agent's context during execution.

What is context injection for AI agents and when do I need it?

Context injection for AI agents is the process of retrieving external SKILL.md files to contextualize actions. You need it when an agent requires a specialized capability that is not pre-loaded, allowing on-demand skill discovery.

Can I search community registries and GitHub for skills to inject into my agent?

Yes, you can search community registries and GitHub for skills. The discovery process supports multiple external sources, applying robust search and metadata extraction to safely handle external content with versioning and source verification.

Does retrieving external SKILL.md content include source verification and versioning?

Yes, retrieving external SKILL.md content includes source verification and versioning. The retrieval process requires safe handling of external content to ensure the injected skill metadata is secure and accurately versioned.

What is the best way to add specialized capabilities to an agent without pre-loading all skills?

The best way to add specialized capabilities without pre-loading is on-demand discovery. This approach fetches the matching SKILL.md content only when a task requires it, optimizing the agent's context window during execution.
