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.

Memory subagent's delete permission narrowed

Not switched on
Useful2 Signal2
Memory

The memory cleanup agent could only delete plain memory files, never anything with flags or outside the folder.

The narrowed delete permission ships with the memory feature, gated on tengu_stone_shell with a false fallback.

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 v2.1.219: 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 v2.1.219. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The consolidation subagent's ability to delete files was tightened to a specific shape of rm command.

Details
  • Only .md files, only inside the memory directory, only outside protected subdirectories such as .git or agents, and with no flags except -f
  • Both the tool-permission denial message and the subagent's own prompt were updated to state the narrower rule
  • Part of the memory feature, gated on tengu_stone_shell, fallback false
Evidence

of .md files inside the memory directory only (outside protected subdirectories like .git or agents

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