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.

Plugin Evals not in their notes

Plugin eval cases must now allow the tools their graders imply, and size timeouts to the real task.

timeout_secondsmax_turns
What

The skill that helps you write plugin evals now states a hard rule: a grader that implies a side effect only passes if the case allows the tool that produces it. A grader checking a file exists needs Write or Edit, a grader checking a tool was used needs that tool, and a task that runs a scan, build or test needs Bash. Authors are told to size timeout_seconds and max_turns to the actual task rather than copying the template.

Details
  • The eval runner backs this up with a warning when a file-based grader is paired with a case that has no tool capable of creating the file.
  • The calibration check tightened: instead of only requiring a non-empty plugin list, an entry must carry no manifest_invalid, disabled_by_default or will_not_load problem. identity_unverified and archive_not_probed are explicitly non-blocking.
Evidence

cannot pass with the granted tools

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