MinTok AST Virtualization for TypeScript
Compile TypeScript codebases into high-density Intermediate Representation (IR). MinTok parses concrete syntax trees via Tree-sitter, strips syntactic boilerplate, and preserves complete architectural invariants so models reason faster with 81.4% fewer prompt tokens.
Why TypeScript Inflates LLM Context Windows
The TypeScript programming language possesses rich syntactic conventions that provide high human readability but introduce substantial token inflation when fed into large language models. Repetitive import statements, verbose type annotations, boilerplate constructors, and extensive docstrings often consume between 65% and 80% of an agent's context window.
MinTok's TypeScript compiler leverages native `tree-sitter-typescript` grammar parsers to tokenize source files into concrete syntax trees. By analyzing node hierarchies, MinTok identifies unreferenced symbol declarations, dead variable bindings, and unused module imports. These nodes are surgically elided before tokenization, achieving an average of 81.4% token reduction while preserving 100% of functional contracts and type bounds.

AST Transformation Benchmark
Compare raw source code tokens against MinTok compiled IR for TypeScript.
// Raw TypeScript (410 Tokens)
import React, { useState, useEffect, useCallback } from 'react';
import { z } from 'zod';
export const UserSchema = z.object({
id: z.string().uuid(),
name: z.string().min(2),
email: z.string().email(),
role: z.enum(['admin', 'user', 'member']),
});
export type User = z.infer<typeof UserSchema>;
export interface UserProfileProps {
userId: string;
initialData?: User;
onUpdate: (user: User) => Promise<void>;
}
export const UserProfile: React.FC<UserProfileProps> = ({ userId, initialData, onUpdate }) => {
const [data, setData] = useState<User | undefined>(initialData);
return <div className="p-4 rounded border bg-white">{data?.name}</div>;
};
// MinTok IR Virtualized (78 Tokens — 81.4% Saved)
@type User = {id:uuid, name:str, email:str, role:enum}
@component UserProfile(userId:str, initialData?:User, onUpdate:(User)->void)
Core TypeScript Compiler Invariants
MinTok never truncates or guesses. These four structural invariants guarantee zero hallucinated imports and 100% type soundness.
Contract & Type Invariant
Public type signatures, trait boundaries, and function interfaces in .ts, .tsx files are strictly preserved so downstream callers compile without type errors.
Exception & Error Boundary
Try/catch blocks, error return values, and panic/raise declarations are maintained to ensure models reason accurately about failure states.
Namespace & Module Path
Canonical import paths and symbol namespaces are preserved, preventing hallucinated relative import paths.
Deterministic Serialization
MinTok IR serializes deterministically across identical AST inputs, maximizing edge KV cache hit rates.
CLI Flags for TypeScript
mintok compile src/ --lang typescript
Compiles all .ts, .tsx files into high-density MinTok IR format.
mintok check --lang typescript --strict
Validates AST syntax invariants and verifies that no syntax errors were introduced.
mintok run --lang typescript --ratio 0.20
Targets a strict 80% context compression ratio during autonomous execution.
TypeScript AST Compilation Questions
Does MinTok break TypeScript syntax when editing code?
No. MinTok uses Tree-sitter parsers to validate syntax before and after every modification, guaranteeing that emitted patches are syntactically sound.
How does MinTok handle TypeScript macros and metaprogramming?
MinTok expands local utility macros into structural type invariants while preserving the underlying macro definition for caller safety.
Can I use MinTok with large multi-file TypeScript projects?
Yes. MinTok builds a project-wide symbol dependency graph across all .ts, .tsx files, enabling surgical cross-file refactoring without context blowouts.
What is the compression speed?
MinTok compiles TypeScript ASTs in less than 3 milliseconds per file inside Cloudflare V8 WebAssembly isolates.
