l4-ide

Formalize legal rules and contracts as executable code

Formalizes legislation, contracts, and policies as executable L4 rules with type-checked decisions and deadline-aware obligations. Eliminates ambiguous legal drafting, manual compliance checks, and untraceable decision logic. Validates rules with the l4 CLI, then deploys them as REST APIs and MCP endpoints with audit-grade evaluation traces.

Frequently Asked Questions

FAQPage Schema
How to install l4-ide?▼

Run `npx skills add smucclaw/l4-ide --all -g -y` in your terminal to install all skills in this suite globally.

What is the L4 language used for?▼

L4 is a domain-specific language for law that turns contracts, regulations, and policies into executable, type-checked rules. It produces auditable decisions, obligation tracking with deadlines, and auto-generated REST APIs.

How do I turn legal text into executable rules?▼

The writing-l4-rules skill guides your agent to model entities with DECLARE, encode decisions with DECIDE, and express obligations using PARTY, MUST, WITHIN, HENCE, and LEST. You then validate the file with `l4 check` or `l4 run`.

Can L4 rules be deployed as an API?▼

Yes. Adding @export annotations publishes functions through jl4-service or Legalese Cloud as REST endpoints, OpenAPI specs, and MCP tools that other AI agents can call directly.

Do I need programming experience to write L4 rules?▼

No. L4 is designed for legal authors, with backtick identifiers that read like plain prose, and your AI agent handles the syntax, validation, and deployment steps for you.
