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.

Effort store split, with a settings writer

Under the hood
Useful2 Signal3
Effort Settings

Session effort and saved-setting effort are now stored separately, and only written when one actually changes.

What

The app store holds session and settings effort as a pair behind a hook, only writing when one of them actually changes, and resume/fork command builders pass the session value along.

Details
  • A new writer persists effortLevel into user settings.
Evidence

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