I built a CLI harness that strips JS/TS function bodies with Babel AST to save 80% context tokens
While working on large Next.js and TypeScript repositories, I noticed AI coding agents (Cursor, Claude Code) constantly burning through context limits. They were reading 500-line implementation files when all they really
While working on large Next.js and TypeScript repositories, I noticed AI coding agents (Cursor, Claude Code) constantly burning through context limits. They were reading 500-line implementation files when all they really needed were the types, interfaces, and exported signatures.
To solve this mechanically, I engineered and open-sourced Apex Agents.
How It Works:
Babel AST Compactor (
npx apex-agents compact):
Parses TypeScript, JSX, and JavaScript using@babel/parserand replaces function bodies with{}while preserving all types, generics, parameters, and exports. In our tests, an ~13k token codebase compacted down to ~1.4k tokens (88.5% reduction) into anAPEX_CONTEXT.mdfile.Pre-Commit Anti-Cheat & Secret Guard (
.git/hooks/pre-commit):
Diff auditor physically prevents AI agents from modifying or skipping tests to fake a "pass", and halts any accidental commit containing high-entropy API keys.38 Specialist Personas (
.cursor/rules):
Injects domain-specific engineering rules directly into.cursor/rulesfor database performance, React 19 architecture, and Lighthouse optimization.Native MCP Server:
Built-in JSON-RPC stdio server ready to plug into Claude Desktop or Cursor MCP settings.
Try it in any repo:
bash:
npx apex-agents init
