7 tools with Chinese descriptions and schemas. All tools have input schemas (Zod-validated) and descriptions present. However, descriptions are domain-specific narrative text (10-200 chars) optimized for Chinese-speaking players, not LLM-optimized English. Parameter descriptions are minimal. No output schemas documented. Tool names use underscores but lack clear verb_noun pattern (e.g., 'tokenlife_start' vs 'start_game'). Error handling returns Chinese error messages without recovery guidance. No tool annotations (readOnlyHint/destructiveHint). Schemas are present but sparse, most parameters lack detailed constraints or format guidance.

• Add output schemas to all 7 tools. Document the structure of game state, card data, and shop inventory. E.g., tokenlife_look should return {year: number, stats: {axis1: number, ...}, card: {type: string, title: string, options: [{index: number, text: string}]}, isEnding: boolean}.
• Rename tools to verb_noun pattern: tokenlife_start → start_game, tokenlife_look → get_game_state, tokenlife_choose → make_choice, tokenlife_shop → view_shop / buy_item, tokenlife_codex → get_codex, tokenlife_save → export_save, tokenlife_load → import_save.
• Add tool annotations: mark tokenlife_choose, tokenlife_start, tokenlife_shop, tokenlife_load as destructiveHint=true; mark tokenlife_look, tokenlife_codex, tokenlife_save as readOnlyHint=true.
• Enhance error messages with recovery guidance. E.g., 'Game not started. Call start_game(name) first.' or 'Invalid choice index. Call get_game_state() to see available options (1-N).'
• Provide English parameter descriptions alongside Chinese. E.g., 'name: Player name (1-10 chars, Chinese/English). Triggers easter eggs if matching known AI names or reincarnation history.' This enables non-Chinese-speaking LLMs to use the server.
