Single tool with minimal definition quality. Tool name 'execute_skill_action' is generic and violates verb_noun clarity (pattern:tool). Description is 127 chars but lacks WHAT/WHEN/WHY context required for LLM selection. Input schema present but parameter 'query_payload' has only a 40-char description, insufficient for LLM reasoning. No output schema documented, LLM cannot predict response structure. No error handling guidance. Tool appears to be a pass-through stub returning hardcoded success, not a real implementation.

• Rename tool to a specific action verb: 'evaluate_flashloan_slippage', 'assess_arbitrage_risk', or 'check_mev_exposure'. Match the actual domain operation.
• Expand tool description to 100-200 chars explaining: (1) What it does (evaluates flashloan slippage risk), (2) When to use it (before executing arbitrage), (3) What it returns (risk assessment with safe/unsafe flag).
• Document 'query_payload' parameter format explicitly. Specify: is it JSON? What fields does it require? Provide a schema or example structure (without literal values LLM might reuse).
• Add output schema showing response fields: guard_evaluation_id (string), pool_id (string), calculated_price_impact_pct (number), slippage_within_safe_bounds (boolean), sandwich_mev_exposure_risk (enum), recommended_split_hops_count (integer), routing_simulation_url (string).
• Implement real error handling: return error objects with actionable messages (e.g., 'Invalid pool_id: must be 42-char hex address') and recovery hints (e.g., 'Try search_pools() to find valid pool IDs').
