+name: PR Visual Recap
+
+# Generates an interactive visual recap (https://github.com/BuilderIO/skills/tree/main/skills/visual-recap)
+# for pull requests that are large enough to benefit from one, posted as a PR
+# comment linking to the Plan app (plan.agent-native.com, NWAC org).
+#
+# Two-stage flow:
+#   1. size-gate — decides whether the PR justifies a recap. Tiny PRs skip
+#      immediately, huge PRs pass immediately, and borderline PRs are judged
+#      by Claude Sonnet against the visual-recap "when to use it" criteria.
+#      Adding the `visual-recap` label to a PR forces a recap regardless of
+#      what the gate would decide.
+#   2. visual-recap — BuilderIO's reusable workflow runs the recap with
+#      Claude Opus and posts/updates the sticky PR comment.
+#   3. publicize-recap — flips the published plan to public visibility so
+#      anonymous visitors to this public repo can open the recap link.
+#      (The recap CLI hard-codes org-only visibility on publish.)
+#
+# Required repo secrets:
+#   PLAN_RECAP_TOKEN        — org-scoped service token for plan.agent-native.com
+#   CLAUDE_CODE_OAUTH_TOKEN — Claude subscription token (`claude setup-token`);
+#                             authenticates the Sonnet size gate
+#   ANTHROPIC_API_KEY       — usage-billed key for the Opus recap only; needed
+#                             until BuilderIO/agent-native#2741 lets the
+#                             reusable workflow accept the subscription token

+# workflow's own group still cancels superseded recap runs per PR; the size
+# gate is cheap enough to run unguarded on rapid pushes.
