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.

Settings can be pre-loaded through the v5 storage backend

Under the hood
Useful1 Signal2
Storage Backend

Settings can be pre-read through the new storage backend, skipping re-parsing when unchanged.

A settings primer only runs when a v5 storage backend is configured, so it is inert otherwise.

settings.json
What

A new primer reads settings.json through the storage backend whenever settings are invalidated, hashing the bytes so unchanged content is not re-parsed, and seeds the result into the settings store. It only runs when a session has a v5 storage backend configured, so it is inert otherwise.

Details
  • Files over the size cap, missing files, and backend errors fall back to the ordinary raw-file read, with a log line.
  • After a fixed number of consecutive failures the primer switches itself off for the rest of the process.

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