Two versions of the PR-review skill ship together and one is chosen when you invoke it.

What
Claude Code carries both PR-review skills: the older one that has the model fill in an HTML template and publish the page itself, and the newer one that has it author a single payload and publish it through the Artifact tool. Both survive as separate embedded files, and a runtime check picks which description and body to use.
Details
- The choice is reported to telemetry as a lane of either
composedorlegacy. - The check that selects the lane resolves through a helper whose inputs are not visible in the bundle, so which lane a given user gets is not determined by anything in this build.
Evidence
te("pr_review_started", { lane: r ? cn("composed") : cn("legacy") });
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
