tokalator：面向 AI 编程的上下文工程工具包，含 VS Code 扩展与 Claude Code 插件

A context engineering toolkit for AI coding. Website + VS Code extension + Claude Code plugin + reusable prompts

Site: tokalator.ai Extension: VS Code Marketplace Claude Code Plugin: tokalator-glossary

Why

AI assistants have finite context windows. When you have 30 tabs open, your assistant's attention gets diluted across irrelevant files. You can't see what's happening -- how many tokens you're using, which files matter, when context rot starts to kick in.

A set of calculators and tools for understanding AI token economics:

Token calculator with real-time pricing across updated models
Model comparison -- context windows, costs, capabilities side by side
Caching calculator for estimating prompt caching savings
Conversation estimator that predicts when context rot will hit
Context optimizer for building token budgets
A interactive course on context engineering
A wiki with +40 terms defined.

The Extension

A VS Code sidebar that tracks your context budget in real time:

Shows token usage as LOW / MEDIUM / HIGH
Ranks open files by relevance to what you're actually working on
One click to close the noise
Pin important files so they're always counted
Chat commands via @tokalator — count, optimize, pin, breakdown, instructions, model

Scores files based on language match, import relationships, path proximity, edit recency, and diagnostics.

Claude Code Plugin

Auto-generates a codebase glossary (symbol index) after /init. Saves tokens by giving Claude a compressed map of your codebase.
