Master of Tokens v2.1: How I cut 92% (24,800+ tokens/session) across 200+ Claude Code skills & Antigravity agents

#ai #claudecode #productivity #opensource

A few days ago, I shared how I gave my Claude Code skills a "bouncer at the door" (master-of).

Since then, my personal skill library exploded from 20 to over 200+ skills, subagents, and custom slash commands.

The result? Claude Code and Antigravity were burning 27,159 system prompt tokens before I even typed my first word.

Today, I released master-of v2.1.0 (The "Master of Tokens" update). Here is what changed and how it cuts 92% (24,877 tokens) per session.

What's New in v2.1.0

  1. One-Shot Batch Parking (mo park --all): Instead of manually configuring dozens of skills, run one command to batch-park every raw skill, agent, and command into dormant domain gates.
  2. Instant Category Confirmation (mo classify --all): Auto-guessed categories are confirmed in bulk with zero prompt noise at session start.
  3. Single-File Agents & Slash Commands: Full lifecycle gating for ~/.claude/agents/*.md and ~/.claude/commands/*.md.
  4. Universal AI Agent Support: Works seamlessly across Claude Code, Google Antigravity (AGY), and any MCP agent (Cursor, Windsurf) via mo mcp.
  5. Zero-Setup Node.js Bundle (mo.mjs): No Bun requirement for Claude Code users—it runs standalone out of the box.

The Numbers (Live Benchmark)

27,159 tok before gating (all 200+ components always-on) − 2,282 tok after gating (domain gates exposed instead) ─────────── 24,877 tok saved per session (92% reduction)

Or clone & run for Antigravity / Cursor:

git clone https://github.com/devrudals/master-of.git ~/master-of
bun run ~/master-of/bin/mo.ts sync
Enter fullscreen mode Exit fullscreen mode
