Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

An auto-generated index of your memory files

Memory not in their notes

Claude can auto-generate an index of your memory files and feed it in as a source.

The auto-memory-index source is off unless a server value enables it, and skipped under CLAUDE_CODE_REMOTE.

Feature flag
tengu_stone_shell Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.224: on

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.224. It isn't a statement about your account. What a flag value here can and cannot tell you

CLAUDE_CODE_REMOTE
What

Claude Code can build a listing of the memory files under a directory and feed it in as an extra memory source, under a virtual path named <auto-memory-index> rather than a real file. The content begins with a generated line naming the directory and noting that the paths below it are relative. It is off unless a server value enables tengu_stone_shell, whose built-in fallback is false, and it is skipped entirely when CLAUDE_CODE_REMOTE is set.

Evidence

<auto-memory-index>

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
