Language Features

A purpose-built language for composable, verifiable AI prompts

→

Resolve Statements

Pull prompts from the registry at compile time. Compose complex workflows from atomic building blocks.

●

Conditional Logic

Branch prompt content based on input variables. Adapt instructions to context without duplicating prompts.

▼

Token Budget Optimization

Lossy compilation for text. Set a token budget and the compiler intelligently compresses while preserving meaning.

◆

Cryptographic Signing

Ed25519 key pairs sign every prompt. BLAKE3 hashing ensures integrity from author to runtime.

▲

Three-Tier Compression

Atoms, compositions, and meta-compositions. Graduated compression preserves critical markers across tiers.

⊖

Version Pinning

Immutable versioning with semver-style resolution. Pin exact versions or track latest for each dependency.
