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.

Plugin Eval Notable not in their notes

Plugin eval now writes report.html and publishes it to claude.ai unless you pass --no-publish.

Feature flag
tengu_quartz_thimble Off by default, switched on for this account

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

This account: on · anonymous baseline: on · compiled default in v2.1.224: off

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.224. It isn't a statement about your account. What a flag value here can and cannot tell you

claude plugin eval--no-publish--publish-report--report
What

After cases run, report.html is written into the results directory even without --report, and the report is published to claude.ai by default rather than only with --publish-report. Pass --no-publish to keep it local. --no-publish and --publish-report together are an error. Publish-by-default is controlled by a server flag whose built-in fallback is on, so with no server value it publishes; an explicit --publish-report ignores the flag entirely.

Details
  • The JSON result is now computed once and shared between writing, publishing and printing.
  • Publishing failures explain that artifacts are turned off for the account, provider or privacy mode, and the failure text names the local copy when one was written.
  • --publish-report's help text changed to match the new default.
Usage
claude plugin eval ./my-plugin --no-publish
Evidence

tengu_quartz_thimble, --no-publish and --publish-report are contradictory — pass at most one.

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