The Mog Programming Language
Hi, Ted here, creator of Mog. - Mog is a statically typed, compiled, embedded language (think statically typed Lua) designed to be written by LLMs -- the full spec fits in 3,200 tokens. - An AI agent writes a Mog program, compiles it, and dynamically loads it as a plugin, script, or hook. - The host controls exactly which functions a Mog program can call (capability-based permissions), so permissions propagate from agent to agent-written code. - Compiled to native code for low-latency plugin execution -- no interpreter overhead, no JIT, no process startup cost. - The compiler is written in…

In plain words
Mog is a statically typed, compiled language designed for AI agents to write and execute their own code as plugins and scripts. It compiles to native code with no interpreter overhead, and the host application controls which functions Mog programs can call through capability-based permissions. The language specification fits in 3,200 tokens to keep it simple for LLMs to generate, and the compiler is written in safe Rust for auditability. Mog is MIT licensed.

What if an AI agent could modify itself quickly, easily, and safely? Mog is a programming language designed for exactly this. Mog is a statically typed, compiled, embedded language (think statically typed Lua) designed to be written by LLMs – the full spec fits in 3200 tokens. An agent hook that runs after context compaction. All I/O functions are provided by the host: import pulls in host-defined types, and optional capabilities degrade gracefully. import agent ; // Agent, Message, Role types optional log ; // silently ignored if not provided // post-compaction hook: re-inject key context that may have been lost pub fn on_post_compaction (session : agent . Session) { log .info (…from moglang.org

MOL – A programming language where pipelines trace themselvesFeb 2026 · github.com · ▲38Hi HN, I built MOL, a domain-specific language for AI pipelines. The main idea: the pipe operator |> automatically generates execution traces — showing timing, types, and data at each step. No logging, no print debugging. Example: let index be doc |> chunk(512) |> embed("model-v1") |> store("kb") This auto-prints a trace table with each step's execution time and output type. Elixir and F# have |> but neither auto-traces. Other features: - 12 built-in domain types (Document, Chunk, Embedding, VectorStore, Thought, Memory, Node) - Guard assertions: `guard answer.confidence > 0.5 : "Too low"` -…
Bolt – A super-fast, statically-typed scripting language written in C2025 · github.com · ▲261I've built many interpreters over the years, and Bolt represents my attempt at building the scripting language I always wanted. This is the first public release, 0.1.0! I've felt like most embedded languages have been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world. Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance. I intend to be…

Han – A Korean programming language written in RustMar 2026 · github.com · ▲208A few weeks ago I saw a post about someone converting an entire C++ codebase to Rust using AI in under two weeks. That inspired me — if AI can rewrite a whole language stack that fast, I wanted to try building a programming language from scratch with AI assistance. I've also been noticing growing global interest in Korean language and culture, and I wondered: what would a programming language look like if every keyword was in Hangul (the Korean writing system)? Han is the result. It's a statically-typed language written in Rust with a full compiler pipeline (lexer → parser → AST →…
