Fighter MCP exposes 4 tools with minimal documentation. Tool names lack action verbs (initialize, observe, act, set_tactic are vague). Descriptions are present but generic (10-50 chars for most). Only 'act' and 'set_tactic' have visible input schemas; 'initialize' and 'observe' show empty input objects with no documentation. Parameter descriptions exist for 'act' and 'set_tactic' but are sparse. No output schemas documented. Error handling is absent, no recovery guidance, no categorization. The game-domain context (fighting game simulation) is clear from code, but tool definitions do not follow agentic tool patterns for clarity, composability, or LLM optimization.

• Rename tools with action verbs: initialize → get_game_briefing, observe → get_battle_state, act → execute_fighter_action, set_tactic → set_fighter_tactic. This signals intent to LLMs and disambiguates from similar tools.
• Expand descriptions to 100-200 chars. For initialize: 'Fetch the game briefing with match setup, including stage geometry, fighter stats, movesets, and initial battle state. Call this once at the start of a match.' For observe: 'Get the current battle state (positions, health, stocks, active moves) without changing held input. Call between actions to assess the situation.'
• Document output schemas for all tools. E.g., initialize returns {stage: {width, height, platforms[]}, fighters: [{id, name, character, stats, movesets}], initial_state: {...}}. Observe returns {tick, fighters: [{player, position, health, stocks, active_move}], ended, winner}.
• Add error handling with recovery hints. E.g., 'Invalid key name. Valid keys: p1-left, p1-right, p1-jump, p1-attack, p2-left, p2-right, p2-jump, p2-attack. Retry with corrected keys.' For act() timeout: 'Simulation timed out. Reduce frames or check game process. Retry with fewer frames.'
• For set_tactic, document the enum values more clearly. Add descriptions for each plan: 'rush: aggressive forward movement and close-range attacks', 'zone: maintain mid-stage control', 'edgeguard: prevent opponent recovery near stage edge', etc. This helps LLMs choose tactics strategically.
