Show HN: SONA – An AI-native serialization format to reduce "Syntax Tax"
fabio2620 Thursday, January 22, 2026The Problem: > Traditional formats like JSON and YAML carry a high "Syntax Tax". In a human-to-machine world, braces and quotes are fine. In a token-based economy, they are expensive overhead. Furthermore, implicit typing leads to "Type Hallucinations" (e.g., a model parsing "NO" as a boolean).
The Solution: > SONA uses "Symbol-Locked Safety." Every value’s type is declared by its first character (# for ints, $ for floats, ? for booleans). This makes parsing unambiguous for the LLM and the parser.
Key Technical Specs:
Token Efficiency: Up to 40% reduction compared to JSON (matches TOON in v1.1).
Performance: Designed for single-pass parsing (Rust implementation included).
Ecosystem: We already have Python/Rust/WASM implementations and a VS Code LSP.
I'm looking for feedback on the specification (SPEC.md) and the symbol-locking approach. Is the trade-off of learning a new syntax worth the token savings in production-scale AI agents?
