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.

Claude Code v2.1.251

Mock replay pins a capped number of recorded interactions

Under the hood
Useful1 Signal2
Plugin Eval

Mock replay pins a capped number of recordings and warns you to prune unused ones.

What

The internal eval mock-replay loader now pins only up to a fixed number of recorded interactions per file and warns to prune recordings no case still reaches once that cap is passed. The cap is an internal constant whose value is not visible in the build.

Evidence

only the first ${oo} are pinned for replay — prune ones no case reaches any more

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