Single tool 'validate_quorum' has a reasonable description (156 chars, within 10-1024 range) but critical schema deficiencies. Input schema present but lacks proper type constraints and descriptions for all parameters. Parameter 'nodes' and 'byzantine_faults' are integers but have no min/max bounds documented, inviting invalid values (e.g., negative numbers, nodes < 3*f+1). The 'payload' parameter accepts 'object' type with no schema constraints, allowing arbitrary input. Output schema is completely undocumented, LLM cannot predict response structure. No error handling guidance; bare exception returns {'error': str(e)} without recovery hints. Tool name 'validate_quorum' is acceptable (verb_noun form) but description could clarify when to use it vs. other consensus tools. No parameter descriptions visible in schema, violates pattern:tool-description baseline (100% of A+ tools have param descriptions).

• Add explicit parameter descriptions to schema: 'nodes' (integer, 4-100, default 4), 'byzantine_faults' (integer, 0-33, must satisfy N >= 3f+1), 'payload' (object with required fields: action, tool, record_id).
• Document output schema with all fields: view (int), sequence (int), digest (string), quorum_size (int), participating_nodes (int), byzantine_nodes (int), consensus_achieved (bool), committed_node_count (int).
• Replace bare exception handling with validation: catch AssertionError and return {'error': 'Invalid cluster config: nodes must be >= 3*byzantine_faults+1. Got nodes=X, byzantine_faults=Y.', 'retryable': false}.
• Add min/max constraints to numeric parameters: nodes (min: 4, max: 100), byzantine_faults (min: 0, max: 33). Document in description: 'Number of nodes in cluster (4-100; default 4)'.
• Clarify payload schema in description: 'Payload to reach consensus on (object with action, tool, record_id fields; default {"test": true})'.
