Hands-on with Codex/Claude Code Context Compression and Utility Features

Hands-on with Codex/Claude Code Context Compression and Utility Features

@dotey

现在 Codex/Claude Code 的上下文压缩确实做的挺好了，加上 Prompt Caching，一个 Session 内持续聊没那么大成本压力了。我现在也越来越多的在一个会话内继续任务。

另外还有两个配套功能是很好的：

• fork，就是从某一个对话位置开分支，只保留该对话前面的历史记录，让上下文更纯粹

• /btw或者/side，在当前会话中提问，通常用于你想起来一件跟当前任务关系不大的事，没必要加入当前上下文中。

True story: I stopped thinking about context since GPT 5.3 Codex

Single project focused threads with the recent capability of codex to spinoff new threads is goated!

Codex continues and goes through compaction but remembers all the important stuff and if not, it’ll look up through the session and find the relevant info

This is also the reason why /goal is so effective as well Show More

One Sentence Summary

The author shares hands-on experience with context compression and Prompt Caching in Codex and Claude Code, and introduces two practical features: fork and /btw.

Summary

dotey explains through practice that context compression in current AI coding tools is already highly efficient. Combined with Prompt Caching, the cost of sustained sessions is significantly reduced, so he increasingly prefers to continue tasks within a single session. The article highlights two utility features: fork (branching from a point in conversation history, retaining prior context but making it cleaner) and /btw or /side (asking questions without disrupting the primary conversation — for example, requesting option explanations in plan mode). These tips offer practical value for developers who use AI coding tools extensively.
