The constraint-monitor server has 4 tools with clear verb-prefixed names and basic schemas, but suffers from significant gaps in parameter descriptions, output documentation, and error handling guidance. Tools are mostly READ_ONLY except update_constraints (WRITE). Naming follows verb_noun pattern (get_*, check_*, update_*) which is good. However, parameter descriptions are minimal or missing entirely, output schemas are not documented, and error recovery guidance is absent. The server operates within a constraint enforcement domain but lacks the LLM-optimization patterns expected of production-grade tools. Average tool score: 48/100.

• Add explicit output schema documentation to all 4 tools. Example for get_constraint_status: 'Returns {status: "compliant"|"warning"|"violation", compliance_score: 0-100, active_constraints: number, violations: [{id, severity, description}]}'.
• Expand parameter descriptions to 50-100 chars each. For 'sessionId', add: 'UUID of the session to query (optional; defaults to current session if omitted). Used to retrieve metrics from prior invocations.'
• Add min/max constraints. For 'limit' in get_violation_history: 'Maximum number of violations to return (1-1000, default 10). Capped at 1000 to prevent memory exhaustion.'
• Document 'pattern' parameter in update_constraints: 'Regex pattern to match constraint violations (PCRE syntax; e.g., "^(function|async function)" to match function declarations). Invalid regex returns error with position info.'
• Add error guidance. For update_constraints, document: 'On pattern validation error, returns {error: "Invalid regex", detail: "Unmatched parenthesis at position X", suggestion: "Add closing ) before position Y"}. Retry with corrected pattern.'
• Clarify tool selection in descriptions. For get_constraint_status vs get_violation_history: 'get_constraint_status shows current compliance state (use for dashboard/monitoring). get_violation_history shows timeline of violations and resolutions (use for audit/investigation).'
• Add confirmation pattern to update_constraints. Support optional 'dryRun: true' parameter: 'If true, validates constraints without applying them. Returns validation results; user must call again with dryRun: false to apply.'
