+## Example Usage
+
+### Goose Prompt
+
+> Our team is facing a challenging decision about our product roadmap. Could you consult the I Ching for some perspective on how to approach this choice?
+
+### Goose Output
+
+I'd be happy to consult the I Ching for guidance on your team's product roadmap decision. Let me cast a hexagram for you using the traditional three coins method.
+─── cast_hexagram | iching ──────────────────────────
+
+
+
+Now let me get a detailed interpretation of this reading for your situation:

+
+## I Ching Guidance for Your Product Roadmap Decision
+
+The oracle has given you **Hexagram 29 - Darkness (The Abysmal)** with a changing line in the 5th position, transforming to **Hexagram 13 - Seeking Harmony (Fellowship with Men)**.
+
+### Key Insights for Your Team's Situation:
+
+**Current Challenge (Hexagram 29):**
+- Your team is facing what the I Ching recognizes as a "repetition of danger" - this suggests you're in a challenging situation that requires careful navigation
+- Like water in a ravine, you need to find the natural path forward rather than forcing your way through
+- The emphasis is on **sincerity and thoroughness** - whatever decision you make, commit to it fully and execute it properly
+
+**Strategic Approach:**
+1. **Flow Like Water**: Don't try to overcome obstacles through force. Instead, find the path of least resistance that still moves you toward your goal
+2. **Fill Every Depression**: Address all the foundational issues before moving forward. Don't skip steps or leave gaps in your planning
+3. **Consistency Over Ambition**: The changing line warns against being "too ambitious." Focus on steady, sustainable progress rather than dramatic leaps
+
+**The Transformation (Hexagram 13):**
+The situation naturally evolves toward **Fellowship with Men** - suggesting that the key to resolving your roadmap challenge lies in:
+- **Building consensus** among team members
+- **Open collaboration** rather than closed-door decisions
+- **Crossing the great water** - taking on significant challenges, but doing so together
+
+### Practical Recommendations:
+
+1. **Acknowledge the Difficulty**: Don't minimize the complexity of your roadmap decision. Accept that it's genuinely challenging.
+
+2. **Seek Team Alignment**: The transformation to "Fellowship" suggests your answer lies in bringing the team together rather than having leadership decide alone.
+
+3. **Take the Conservative Path**: The 5th line specifically advises against overambition. Choose the roadmap option that gets you "out of danger" rather than the most aggressive one.
+
+4. **Focus on Execution**: Once you decide, commit fully. The hexagram emphasizes that success comes from thorough implementation, not perfect strategy.
+
+The I Ching suggests this challenging decision will ultimately strengthen your team's unity and collaboration if approached with patience, sincerity, and collective wisdom.
