Cloud hypervisor?

@copilot update the page to specifically mention the supported sandboxes, e.g., cloud-hypervisor, gvisor, and docker-sbx, just as the page lists supported agents

Skills-Based Review 🧠

This is a small, well-scoped documentation change (homepage content restore) with a corresponding, expected lock-file regeneration. Verified both new links (/gh-aw/reference/self-hosted-runners/ and /gh-aw/reference/glossary/#docker-sbx) resolve to existing content. No code logic, tests, or architecture changes are involved, so /tdd, /diagnosing-bugs, and /codebase-design do not surface actionable findings here — content-only PRs like this are out of scope for those skills.

Nothing blocking. Approving.

Reviewed with Impeccable critique/audit modes (docs-only content restore: new/re-added FeatureCards, updated intro copy, removed mermaid diagram, updated docs-noob-tester lock metadata). No blocking issues found. Left one minor, non-blocking icon-reuse suggestion inline.

  </FeatureCard>
-  <FeatureCard icon="mark-github" title="GitHub Integration" href="/gh-aw/reference/github-tools/">
-    Deep integration with Actions, Issues, PRs, Discussions, and repository management
+  <FeatureCard icon="server" title="Self-Hosted &amp; ARC Runners" href="/gh-aw/reference/self-hosted-runners/">


Minor: this new Self-Hosted & ARC Runners card reuses icon="server", the same icon already used two cards later for Use at Scale in Organizations (line 55). Since both live in the same 3-column grid, the repeated icon reduces visual distinctiveness/scanability across the row. Consider a more specific octicon (e.g. cpu, rocket, or terminal) for one of the two cards.

@copilot please address this.

Verdict

No blocking issues in the changed lines.

Why this stays non-blocking

The new homepage copy is consistent with existing reference docs: cloud-hypervisor is already documented as preview-only, docker-sbx already points at the glossary entry used here, and the self-hosted runners page already documents the Linux and ARC/DinD constraints that this card links to.
