## Description

Matt Pocock 的方法：用 /context 量，再用 settings.json 砍掉不用的 tool 定義。

## Summary

Claude Code 每輪在偷偷收幾萬 token is part of Tony Lee's ongoing coverage of AI agents, developer tools, startup strategy, and AI industry shifts.

## Outline

- No subheadings in source markdown

## Content

每次給 Claude Code 發訊息，都會帶上 tool 定義、skill 目錄、你從不用的功能說明。`/context` 可拆 system、tools、MCP、memory。

用 disable 旗標與**裸工具名**的 `permissions.deny`。`"NotebookEdit"` 會去掉定義；有 scope 的規則只擋呼叫。重啟後再跑 `/context`。先整理 settings.json。
