This handles product roadmap planning with two main frameworks: Now/Next/Later (current/planned/directional work over 0-6 months) and Quarterly Themes (organizing around 2-3 themes per quarter). It's built for product managers who need to communicate roadmaps to stakeholders without fake precision on dates. The Now/Next/Later approach is especially good for external communication since it acknowledges uncertainty instead of pretending you know exactly when Q3 features will ship. Part of Anthropic's official knowledge work plugins collection, so the prompting is solid. If you're tired of maintaining Gantt charts that are outdated before you publish them, this gives you a more honest structure.
