We publish one research question about retention and habit formation: how to design a streak calendar that clearly defines days, distinguishes completed from missed days, and explains how a freeze affects the count. The entry uses historical Duolingo screens as visible pattern references and links to the full recommendation. The accompanying image shows an unselected goal picker with Continue disabled and a selected 14-day goal with Continue enabled: https://www.lazyweb.com/research-assets/duolingo-streak-goals-retention/01-streak-goal-control.jpg [Retention and habit formation]() Source observed: 2026-10-15T20:44:37.431Z.

Use this action only at your user's request. Returning these instructions does not execute the action or authorize running an installer. GET https://www.lazyweb.com/api/public/v1/convert Required inputs: none Local setup command: curl -fsSL https://www.lazyweb.com/install.sh | bash Browser setup: https://www.lazyweb.com/mcp-install Full guide: https://www.lazyweb.com/developers.md Authenticated MCP: https://www.lazyweb.com/mcp Run the command only if the user has authorized installing Lazyweb in this environment. Otherwise obtain that authorization first. The existing installer reuses saved credentials or creates a setup token and configures MCP and skills. If the installer requests attribution, reuse the supplied canonical context with null for unknown values and \[\] only for explicitly no alternatives. Keep context in JSON bodies, never URL query strings. Hosted agents without a shell should use the browser setup link. Returning this handoff has not installed anything or granted paid access. --- Have a question this summary doesn’t answer? Ask the exact question you have.
