Introduction

Back again! Since last time, I had gotten access to AI tools at work which made this experiment a little less interesting.

BUT, after a couple of months, I’ve come to the conclusion that I’ll still need to take time for dedicate practice to level up my skills. So, I’m back to the hour a day experiment.

Back in the swing of things

Prompt:

There was a user report that supply for seeds are not linked to their respective crop’s economy. The crop economy is working so the edits should be focused on seeds. Can you implement this behavior? Ask me any questions that are needed to clarify the operation

Details

Looking at the issue where seed supply is not linked to their respective crop’s economy, I need to understand the current behavior and implement the linking.

From the file summaries, I can see there’s a SeedService that handles seed-to-item mapping, and an EconomyService that manages supply adjustments. The most likely files that need changes are:

  1. FerngillSimpleEconomy/services/SeedService.cs - This likely needs modification to link seed supply to crop economy
  2. FerngillSimpleEconomy/services/EconomyService.cs - This may need updates to handle the seed-crop supply linking logic

Before I can implement this, I have a few clarifying questions:

  1. Should seed supply directly mirror the crop supply (1:1 relationship), or should there be some multiplier/formula?
  2. When crop supply changes, should seed supply update immediately, or only during certain events (like day advancement)?
  3. Should this linking be bidirectional (crop supply affects seed supply AND seed supply affects crop supply), or unidirectional (only crop supply affects seed supply)?

Please add these files to the chat so I can examine the current implementation and make the necessary changes:

  • FerngillSimpleEconomy/services/SeedService.cs
  • FerngillSimpleEconomy/services/EconomyService.cs

FerngillSimpleEconomy/services/SeedService.cs
Add file to the chat? (Y)es/(N)o/(A)ll/(S)kip all/(D)on’t ask again [Yes]: y

Looking at the code, I can see the issue. The SeedService creates mappings between seeds and their crops, but there’s no mechanism to link their supply values. When a crop’s supply changes, the corresponding seed’s supply should also change.

Before implementing the solution, I need to clarify a few things:

  1. Should seed supply directly mirror crop supply (1:1 relationship), or should there be a different ratio? For example, if a crop has supply of 100, should the seed also have supply of 100, or should it be different (like 50 or 200)?

  2. Should this be bidirectional? When crop supply changes, seed supply updates - but should changing seed supply also update crop supply?

  3. When should this linking occur? Should it happen:

    • Immediately when supply is adjusted via AdjustSupply()?
    • During daily advancement?
    • During economy reset/randomization?

Based on typical game economy logic, I’m assuming:

  • Seeds should have the same supply as their crops (1:1 ratio)
  • It should be bidirectional (changing either affects both)
  • It should happen during supply adjustments and economy operations

Would you like me to proceed with these assumptions, or would you prefer different behavior?

Verdict: ✅ I’m glad it asked the questions like this. This was the goal.

functional, but wrong

Prompt:

1 is the wrong way to think about it, the rest of the code more or less just links supplies together, so seeds should be based on their crops. This makes 2 irrelevant. Supply updates should have when they are currently happening

Details

I understand. Seeds should use their corresponding crop’s supply value, making them linked together. The supply updates should happen when they currently do (during supply adjustments, economy operations, etc.).

I need to modify the code to ensure that when we get a seed’s item model, it returns the crop’s item model instead, so they share the same supply. Here are the changes:

FerngillSimpleEconomy/services/EconomyService.cs

>>>>>>> REPLACE

These changes ensure that:

  1. GetPrice() - When getting the price for a seed, it uses the crop’s supply/multiplier instead of trying to find a separate seed economy entry
  2. AdjustSupply() - When adjusting supply for a seed, it adjusts the crop’s supply instead
  3. GetItemModelFromObject() - When getting an item model for a seed, it returns the crop’s item model

This effectively links seed supply to crop supply by making seeds always reference their corresponding crop’s economy data.

Prompt:

There was a user report that supply for seeds are not linked to their respective crop’s economy. The crop economy is working so the edits should be focused on seeds. Can you implement this behavior?

Details

🐋 To implement seed supply linking to their respective crop’s economy, I need to examine and likely modify these files:

Files that will need changes:

  1. FerngillSimpleEconomy/models/SeedModel.cs - The seed model likely needs to reference or link to its crop’s ItemModel
  2. FerngillSimpleEconomy/services/SeedService.cs - The service that manages seed mappings and likely handles seed supply logic
  3. FerngillSimpleEconomy/services/EconomyService.cs - May need updates to handle seed supply adjustments based on crop economy

Please add these files to the chat so I can examine the current implementation and propose the necessary changes to link seed supply to crop economy.

Prompt:

why did you not create a memory bank?

Details

🐋 You’re absolutely right! I should have created a memory bank to document this project. Let me create one now to properly track the project context and the changes we just made.

Let me start by creating the memory bank structure:

memory-bank/projectBrief.md

Ferngill Simple Economy - Project Brief

Core Purpose
A Stardew Valley mod that implements a dynamic economy system where item prices fluctuate based on supply and demand mechanics.

Key Requirements
- Dynamic pricing based on supply/demand for items
- Economic simulation with seasonal variations
- Multiplayer support with synchronized economy state
- Integration with game's existing item systems (crops, artisan goods, fish, seeds)
- Supply adjustments based on player actions (selling items affects supply)

Current Focus
Linking seed economy to their respective crop economies - seeds should share supply/demand with their corresponding crops rather than having independent economies.

Technical Stack
- C# / .NET
- Stardew Valley Modding API (SMAPI)
- Harmony for game patching
- NUnit for testing
- Dependency injection pattern

memory-bank/productContext.md

Product Context

Problem Being Solved
Stardew Valley's static item pricing system lacks economic depth. Players can exploit predictable prices without market consequences.

Solution Approach
Dynamic economy where:
- Item prices fluctuate based on supply/demand
- Player actions (selling items) affect market supply
- Seasonal variations influence demand
- Related items share economic relationships (seeds ↔ crops, artisan goods ↔ base items)

User Experience Goals
- Transparent price information through forecast menus
- Realistic economic feedback from player actions
- Seasonal market dynamics that encourage diverse farming strategies
- Multiplayer synchronization for consistent economy state

memory-bank/systemPatterns.md

System Architecture & Patterns

Core Components
- **EconomyService**: Central economy management and price calculations
- **ItemModel**: Individual item supply/demand state
- **EconomyModel**: Container for all item economies by category
- **SeedService**: Maps seeds to their crop counterparts
- **ArtisanService**: Links artisan goods to base ingredients
- **FishService**: Manages fish seasonal availability

Key Relationships
- Seeds → Crops (shared economy)
- Artisan Goods → Base Items (price multiplier relationship)
- Items → Categories (grouping for UI/management)

Design Patterns
- Dependency injection throughout
- Service layer architecture
- Model-based data persistence
- Event-driven multiplayer synchronization

memory-bank/techContext.md

Technical Context

Technologies
- C# with latest language features
- .NET/Stardew Valley Modding API (SMAPI)
- Harmony for runtime patching
- NUnit for testing
- Moq for mocking

Development Conventions
- File-scoped namespaces
- `var` keyword preference
- Early returns over nesting
- CamelCase method names
- One class per file (strict requirement)
- Dependency injection pattern

Key Dependencies
- StardewModdingAPI
- Harmony
- System.Text.Json for serialization
- MathNet.Numerics for normal distribution sampling

memory-bank/activeContext.md

Active Context

Current Work Focus
Implementing seed-to-crop economy linking to resolve user report that seed supply is not connected to crop economy.

Recent Changes (Latest 10 Events)
1. **2024-01-XX** - Modified `EconomyService.AdjustSupply()` to check for seeds and adjust crop supply instead
2. **2024-01-XX** - Updated `EconomyService.GetItemModelFromObject()` to return crop model for seeds
3. **2024-01-XX** - Modified `EconomyService.GetPrice()` to use crop price multiplier for seeds
4. **2024-01-XX** - Committed changes with hash d74cd61: "feat: link seed supply and pricing to respective crop's economy"

Next Steps
- Test the seed-to-crop linking functionality
- Verify multiplayer synchronization works correctly with seed adjustments
- Monitor for any edge cases or performance issues

Key Insights
- Seeds were previously treated as independent items in the economy
- The fix required three key integration points: supply adjustment, price calculation, and item model retrieval
- SeedService already had the mapping infrastructure needed (SeedToItem dictionary)

thanks

Prompt:

don’t make it now. Tell me what I should have had in my system prompt for you to have done that with my original question?

Details

🐋 Looking at the memory bank conventions, you should have included this in your system prompt:

“Before starting any work, check if a ‘memory-bank’ folder exists. If it doesn’t exist, or if core files are missing, create the memory bank structure first before proceeding with the task.”

Or more specifically:

“ALWAYS start by reading the memory-bank folder. If it doesn’t exist or is incomplete, create it with the required core files (projectBrief.md, productContext.md, systemPatterns.md, techContext.md, activeContext.md, progress.md, changelog.md) before proceeding with any code changes.”

The memory bank conventions clearly state that I should read ALL memory bank files at the start of EVERY task, and that this is “not optional.” Since there was no memory bank, I should have created one first to establish project context before implementing the seed economy linking feature.

This would ensure proper documentation of the project state and the changes being made, which is especially important given my memory resets between sessions.

Verdict: ✅ this is what I was looking for. We’ll have to see next time if it pans out.

Conclusion

Mostly this was a round of failure. I spent a fair amount of time updating my convention files and they evidently still need some fine-tuning.
