X07, a language for autonomous coding – structured, machine-readable code edits and diagnostics

Summary: X07 is a programming language designed to reduce common agent coding errors by using a canonical JSON AST format, machine-readable diagnostics, and automated repair loops. It compiles to native binaries via a C backend and supports deterministic execution environments for testing and deployment.

What it does

X07 uses a JSON AST source format and RFC 6902 JSON Patch for code edits, providing stable, machine-readable diagnostics with quickfix patches. It automates build, lint, and repair cycles with bounded iterations and supports deterministic execution worlds for reproducible testing.

Who it's for

It targets developers building autonomous coding agents who need predictable syntax editing, diagnostics, and execution workflows.

Why it matters

X07 addresses failures caused by syntax errors and human-oriented compiler messages by enabling precise, automated fixes and reproducible execution environments.
