Mimosa Plugin Workspace Reached 334 GiB in One Case
A first-hand report describes a Nov. 6, 2026 inspection of a Mac workspace where Codex was used and runtime data from the Mimosa code-security plugin was present. The author measured the workspace’s root .mimosa directory at about 334 GiB before cleanup and about 203 GiB in a later measurement. Both figures refer to the same root directory, but they were recorded at different times; the report says the numbers should not be treated as directly comparable and that the remaining data cannot automatically be considered junk. The author also notes that not every older session was tested for restoration. The recommended process is to stop related Agent work, back up needed records, check official cleanup options, and review individual candidates before deleting them rather than removing the entire directory.
This single-user case shows that an AI coding security plugin can leave substantial local state in a workspace and provides a cautious way to assess and clean it. The evidence does not establish a general growth rate or prove that all Mimosa installations behave this way.
最近，我用 AI Agent 做项目，做着做着就报错了硬盘已满。
Wait, Wait, Wait。我这512G的盘才用了一个月不到啊。
顺着占用往下查，一个平时看不见的目录引起了我的注意：.mimosa。在一次测量中，它占用了约 334 GiB。
这里的 GiB 是电脑常用的二进制容量单位。你可以先把它理解成“约 334 GB 这个量级”，不用被单位劝退。
这次排查发生在 2026 年 11 月 6 日。我在 Mac 上使用外置硬盘，借助 Codex 检查项目；工作区里也有 Mimosa 安全插件留下的运行数据。
