CLAUDE.mdArea: what it touches
ImprovementsKind: in v2.1.290,
ImprovementsSection of the release
Unclear It is not confirmed that this fixes a folder's CLAUDE.md being added again after resuming or compacting, nor which plugin system runs this code.
What
CLAUDE.md files hold instructions that Claude Code adds to the conversation. Their loading now keeps a record of files already held, so the same file is not added again. The code that handles them also reacts to more moments in a session than before:
running a command
compacting, when Claude Code shortens a long conversation to save space
submitting a prompt
the start and end of a turn
mentioning a file or folder with @
Before, it only reacted when building the prompt's context, when starting a subagent (a helper Claude starts for part of a task) and when reading a file. Mentioning a path now also brings in the instruction files inside it.
Why
You should see fewer duplicate copies of the same CLAUDE.md in a conversation, and @-mentioning a folder now brings in its nested instructions.
