SKILL.MD
Shipping with MCP server.
What Is SKILL.MD
SKILL.MD is a structured knowledge file format popularized by Abstract for AI coding agents. Unlike raw documentation, a SKILL.MD file provides decision tables, workflows, gotchas, and quick-reference data — the kind of information an agent needs to build correctly on a platform.
Abstract publishes their own SKILL.MD at docs.abs.xyz/skill.md. Litany follows the same format.
Install
npx skills add https://litany.ggThis installs the Litany skill into any compatible coding agent (Claude Code, Codex, or any agent that supports the skills format).
What the Litany Skill Contains
- Contract addresses for Litany Inscriptions and Hollows on Abstract mainnet and testnet
- ABI references for key functions (
getCardIndices,getCardText,getOwnedCards, etc.) - The inscription structure (7 lines: name, class, 4 parameters, trait)
- How to read and interpret inscription data from external contracts
- Common integration patterns for game developers
- Gotchas and Abstract-specific configuration (chain ID, RPC endpoints, compiler settings)
When to Use SKILL.MD vs SDK vs MCP
| Need | Use |
|---|---|
| Building a game that reads Litany assets | SKILL.MD + direct contract calls |
| Building an agent that plays Litany | MCP server |
| Building a custom tool or backend service | SDK |
| Teaching a coding agent about Litany | SKILL.MD |
Compared to Abstract’s SKILL.MD
Litany’s SKILL.MD is complementary to Abstract’s. An agent building on Litany should install both:
npx skills add https://docs.abs.xyz # Abstract platform knowledge
npx skills add https://litany.gg # Litany protocol knowledgeAbstract’s skill teaches the agent about chain configuration, AGW integration, and deployment workflows. Litany’s skill teaches it about inscription data, Hollow contracts, and game integration patterns.
