AI / Network Interface Fixes

• Fixed: SiliconFlow speech recognition returning HTTP 422 errors
• Fixed: Multiple compatibility issues when using newer models such as GPT-4.5 with the updated OpenAI API

Performance Optimizations

• Optimized: Refactored the rendering logic for item forms, significantly reducing render time for item figurines and seats
• Optimized: Improved the display logic for maid attribute values to prevent UI display abnormalities caused by value overflow

AI Agent Updates

The maid's AI chat functionality has been significantly refactored in this update, with systematic optimizations based on mainstream Agent architecture design principles. Currently, only the Touhou Little Maid: Epistalove add-on has a known compatibility crash; all other add-ons are compatible.

Provider Support Updates

• Updated model lists for providers including Aliyun, SiliconFlow, OpenAI, and others to their latest versions
• Removed Tencent Hunyuan provider
• Added the following default providers:
  • Gemini
  • Grok
  • OpenRouter
  • GLM
  • MiniMax (supports both LLM and TTS)
  • KiMi
  • Tencent Cloud (ASR only)

UI Interaction Improvements

This update significantly lowers the barrier for configuring AI-related features and greatly improves ease of use.

• All AI chat-related settings have been unified into the UI panel opened by pressing T while facing the maid; the corresponding tabs in the maid's original GUI have been removed
• The UI panel includes: provider settings, maid persona prompt editor, chat history viewer and deleter, LLM / TTS / language options, and provider configuration modules
• The panel displays real-time cumulative Token usage
• Provider configuration now includes an authentication mechanism, with full consideration for single-player, LAN, dedicated server host, and client scenarios — server administrators no longer need to worry about key and configuration security
• Provider configuration can now be fully modified in-game without manually editing JSON config files
• The chat input box supports using the up/down arrow keys to quickly recall previous inputs for re-editing
• A "None" option has been added to TTS provider selection, allowing players to disable speech synthesis on the client side

AI Chat Functionality Refactor

• Prompt Optimization

  • The maid can now more accurately recognize player intent and call the correct tools
  • Highly relevant contextual information is automatically injected into each conversation to improve instruction recognition efficiency

• Conversation Robustness Improvements

  • When a large model hallucinates or incorrectly calls a tool, the system will automatically trigger a retry mechanism to guide the model to self-correct
  • Message history structure is validated before each conversation to prevent HTTP 400 errors (previously triggered frequently when using models such as DeepSeek)
  • If the associated maid entity no longer exists, the conversation session will be immediately terminated to prevent erroneous calls

• Cache Hit Rate Optimization (improving cache hit rate effectively reduces API costs and speeds up model responses)

  • Conversation cache hit rate has been improved from approximately 50% to approximately 85%

• Tool Call Adjustments

  • Added more callable tools, including: toggling the maid's sit state, Home mode, work schedule, setting attack targets, etc.
  • Increased the maximum number of rounds in a tool call chain and introduced multiple circuit-breaker mechanisms to support AI combining multiple tool calls for complex operations while preventing infinite loops that could cause abnormal Token consumption
  • Some game context with rich content is now fetched on-demand via the tool call mechanism, reducing baseline Token usage
  • Use the command /tlm ai_chat context to output all currently available game context information
  • Use the command /tlm ai_chat tool to output all currently available tool lists

• Skill System

  • Added the Skill system: standard Skill files can be placed in a specified path within the config folder or data pack, and the system will inject them into the conversation context at the appropriate time
  • A built-in default Skill is included, containing knowledge about the maid mod itself, enabling the maid to correctly answer questions about the mod
  • Use the command /tlm ai_chat skill to output all currently loaded Skills

• Context Compression

  • When the conversation history reaches a certain length, the system will automatically compress and summarize the history, preserving conversation continuity while effectively reducing Token usage

• UI Feedback Improvements

  • When the maid executes a tool call, the chat bubble will refresh in real time to display the current tool call status, reducing player confusion during wait times
  • Adjusted the maximum width of regular text chat bubbles to prevent overly long single lines from affecting readability

New Content

New Models

• Updated: K Snail model
• Added: Holy Kitsune, Elf Kitsune (Starfield), Survivor Kitsune (Rosemist), Mini Kitsune (White Polarbear), Tactical Kitsune (Sodaball Pixel)
• Added: Nian Gao Fox (Perfect Freeze)
• Added: Missing characters from Touhou Kinjokyou (FumoFumo)
• Updated: Reimu and Marisa models (CrystalSun)

Sophisticated Backpacks Support

Added compatibility support for Sophisticated Backpacks: after placing a Sophisticated Backpack in the maid's Curios slot, the maid can interact with the backpack normally, including taking out and putting in items. (by CentaureaHO)

Mini Maid Fairy

When a maid fairy spawns, there is now a 10% chance to spawn a Mini Maid Fairy instead. The Mini Maid Fairy has a slightly higher flight speed than a regular maid fairy and drops double P-Points upon being killed.

FallbackIngredient

Added the FallbackIngredient recipe ingredient type, used to implement differentiated crafting inputs in a multi-mod environment (the design concept is similar to the multi-mod adaptation approach of the Avaritia crafting table).

This ingredient type iterates through the fallbacks list in order and selects the first entry whose corresponding mod is installed as the actual crafting input, implementing logic such as "use item from mod A if installed, otherwise fall back to B".

Usage Example:

The following recipe demonstrates an altar recipe that uses the millstone from kaleidoscope_cookery if that mod is present, otherwise falls back to vanilla planks, while always requiring a diamond as a fixed ingredient:

{
  "type": "touhou_little_maid:altar_recipe",
  "output": {
    "item": "touhou_little_maid:bookshelf",
    "count": 1
  },
  "power": 0.1,
  "ingredients": [
    {
      // Required type parameter
      "type": "touhou_little_maid:fallback_ingredient",
      // Ordered list; the first entry whose mod is installed will be used as the actual input
      "fallbacks": [
        {
          // Use the millstone from kaleidoscope_cookery if present
          "modid": "kaleidoscope_cookery",
          "value": {
            "item": "kaleidoscope_cookery:millstone"
          }
        },
        {
          // Fallback: use vanilla planks (tag matching)
          "modid": "minecraft",
          "value": {
            "tag": "minecraft:planks"
          }
        }
      ]
    },
    // Fixed ingredient: diamond (vanilla Ingredient syntax)
    {
      "tag": "forge:gems/diamond"
    }
  ]
}
