What's wrong with this entry?
A new memory system gives Claude a persistent, file-based scratchpad stored in a configurable memory directory. Information saved there carries over to future sessions.
- Enabled by the
tengu_stone_shellfeature flag. - Claude receives detailed guidance on what makes a good memory: applicable (prevents repeated mistakes), durable (recurring workflows), and legible (self-contained, full sentences).
- Claude is instructed to write memory before the end of any turn where the user corrects it or it discovers something new about the environment.
- Memory files use markdown with frontmatter (
name,descriptionkeys). - This is separate from the existing
#/memoryshortcut system; it's a lower-level persistent layer.
"You have a persistent, file-based memory stored at {memory_dir}." (search for "TVh" or "tengu_stone_shell")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
