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.

Cache diagnostics keep the previous request body directly

Under the hood
Useful1 Signal1
Caching

Cache diagnostics keep the previous request body directly instead of rebuilding it.

What

The per-request cache-diagnosis state now stores the current and previous request content itself rather than functions that would rebuild them. Same telemetry, different retention.

Evidence

prevGlobalCacheStrategy

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