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.

Skill and command text de-duplication cache moved into session state

Under the hood
Useful1 Signal1
Session State

The skill and command text de-duplication cache now clears with the rest of session state.

What

The map that reuses one copy of an unchanged skill or command file body was a process-lifetime global; it is now a field on the shared session state container, so it is cleared along with everything else on reset.

Evidence

skillContentIntern

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