Single tool 'execute_skill_action' has a minimal schema with only one string parameter. Description is generic marketing language ("Execute deterministic, zero-dependency Smart Contract Security & Web3 Sentinel operations") that does not explain WHAT the tool does, WHEN to use it, or WHAT it returns. Parameter 'query_payload' lacks any meaningful description beyond 'Input execution payload', ambiguous and unhelpful. No output schema documented. Tool appears to be a pass-through stub that always returns a hardcoded success message regardless of input, suggesting it is non-functional or a placeholder. No error handling, no validation, no guidance for LLM on how to construct the payload or interpret results.

• Replace marketing language with functional description: 'Detects anomalies in cross-chain bridge reserve invariants by comparing locked source amounts with minted target amounts. Returns audit results with balance deltas and circuit breaker recommendations. Call this to validate bridge health before transactions.'
• Document the 'query_payload' parameter format explicitly. Specify whether it is JSON, a query string, or a structured object. Provide the expected schema or example: 'JSON object with keys: bridge_name (string), source_chain (string), target_chain (string), locked_source_amount (number), minted_target_amount (number).'
• Add explicit output schema to tool definition: 'Returns object with fields: bridge_audit_id (string), bridge_name (string), source_chain (string), target_chain (string), reserve_invariant_balanced (boolean), balance_delta_usd (number), anomalous_outflow_spike_detected (boolean), circuit_breaker_trip_recommended (boolean), bridge_telemetry_url (string).'
• Implement actual anomaly detection logic instead of stub. Parse query_payload, validate inputs, compute variance, and return real results. Add validation: reject payloads missing required fields with error message 'Missing required field: <field_name>.'
• Add error handling: return structured errors with actionable guidance. E.g., 'Invalid bridge_name: "UnknownBridge". Available bridges: OmniBridge_USDC, Stargate_USDT, Across_DAI.' Categorize errors as retryable (network timeout) vs user-fixable (invalid bridge name).
