Plan Artifact Template: CDS Design Tokens and TAB_TITLE Slot

ImprovementsSection of the release

The plan artifact HTML template has been upgraded with the official Anthropic CDS (Component Design System) token set and a new title control slot.

Details
  • Added {{TAB_TITLE}} slot: controls the browser <title> element separately from the document heading {{TITLE}}. The .md publish path sets it to the filename while the visible <h1> shows the document heading
  • Replaced hand-coded CSS color literals with vendored @ant/cds design tokens (the full token CSS is embedded verbatim and drift-tested in CI)
  • Adds syntax highlighting for code blocks using highlight.js with language detection
  • The plan-artifact skill instructions updated to reflect the new four-slot fill contract ({{TITLE}}, {{TAB_TITLE}}, {{EYEBROW}}, {{SUMMARY}})
Evidence

(search for "TAB_TITLE", "BEGIN vendored @ant/cds tokens", "artifact-plan.html")

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