MCAI Assistant

v1.7.0

Bug Fixes

• Fix approval notification IDs displaying as %s instead of actual numbers
• Fix SSE streaming tool_calls parse crash when field is JsonNull
• Fix KnowledgeBase search(null) NPE
• Fix concurrent access to ChatHandler history list
• Fix SearchRouter unbounded thread pool — replaced with fixed-size ThreadPoolExecutor
• Fix resolved approval items not being removed from queue (memory leak)
• Fix cross-world chat log leakage — logs now cleared on world change
• Fix /aidebug stop not resetting state on world exit

New Features

• Persona system — Inject different AI personalities for varied conversations
  • 8 built-in personas: Tsundere, Pirate Captain, Chuunibyou, Gentle, Villager, Piglin, Enderman, Creeper
  • Custom persona support via JSON files in config/mcai/personas/
  • Commands: /aipersona list|set|current|view|reload
  • Hover preview and click-to-select in /aipersona list
• SSE streaming support — enableStream config option for APIs that only support streaming
• Configurable timeouts — wikiConnectTimeoutSeconds, wikiRequestTimeoutSeconds
• 3 new player inspection tools — get_player_effects, get_player_advancements, get_player_inventory (bypass command restrictions)
• AI debug logging — /aidebug start|stop|status for troubleshooting

Improvements

• OpenAIClient refactored — split into ApiClient (HTTP transport), ToolDefinitions (tool schema), OpenAIClient (facade) for maintainability
• Knowledge base online-only — Wiki search replaces local knowledge base for always-fresh results
• Queue-full handling — friendly error message instead of silent drop when AI is busy
• /aireload full reload — now reloads all components (config, AI client, search router, persona list)
• Admin approval improvements — removed resolved items from queue, click-to-approve notifications
• Version-aware prompts — AI now understands 26.x version numbering and searches more effectively
• Command chain support — batch multiple commands with execute_command_chain, cancel with /aicancel
