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-break diagnostics kept in a per-session file

Under the hood
Useful1 Signal2
Diagnostics

Prompt cache-break diagnostics are written to a per-session temp file instead of only memory.

What

Diagnostic state about prompt cache breaks is now written to a file in the temp directory named per session, instead of living only in memory.

Details
  • The directory's permissions are checked before each access, loading is capped by both file size and entry count, and the file is deleted once empty.
  • Entries belonging to other sessions are evicted first when the cap is hit.
  • Writing is behind a separate enablement check, so persistence does not necessarily happen in every session.
