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.

Fewer spurious "plugin cache in use" failures

Plugins

Bogus "plugin cache in use" markers no longer block your installs.

What

The markers Claude Code writes to record that a plugin cache version is in use are now checked before being trusted. A stray file where a marker directory should be is removed with a warning instead of blocking the install, and pruning retries a bounded number of times.

Details
  • After cleanup the affected version is treated as unpinned until a session marks it again.
Evidence

Removed a non-directory ${Ou} at ${e}; the version reads unpinned until a session marks it again

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