+ * The coding-agent handoff prompt.
+ *
+ * The wizard finishes a successful run by emitting `posthog-setup-report.md` —
+ * which now ends with a "Verify before merging" checklist the agent fills in
+ * from the context-mill skill (see the basic-integration conclude step). This
+ * is the one-line prompt the operator pastes into their own coding agent to
+ * close the gap between "wizard finished" and "PostHog merged": read the
+ * report, work the checklist, open a PR.
+ *
+ * Kept as a pure helper so the exact wording is easy to review and test in
+ * isolation. It is surfaced through `OutroData.handoffPrompt`, which the wizard
+ * prints to the terminal's main buffer on exit (where it survives in scrollback
+ * and stays triple-click-selectable); it is NOT written into any file — the
+ * verification content itself lives in the report.
+ *
+ * The wording asks the agent to investigate each checklist item and get the
+ * operator's explicit consent before making any changes — so actions with real
+ * implications (e.g. uploading source maps, editing CI) are surfaced and
+ * approved, not applied silently. It deliberately stops there: no PR mandate or
+ * edit-style rules, since the operator pastes this into their own agent and
+ * governs how changes ultimately land.
+ *
+ * Background: https://github.com/PostHog/wizard/issues/447
