Tickscope demonstrates solid tool naming (verb-first: get_, compute_, detect_, screen_, analyze_) and comprehensive parameter schemas with type definitions. All 10 tools have descriptions (avg ~80 chars) and input schemas. However, descriptions are terse and lack LLM-optimized guidance on WHEN to use each tool vs. alternatives. Output schemas are not documented, LLMs cannot predict response structure. Error handling is absent from visible code. Parameters lack enums for constrained values (e.g., 'exchange' accepts free-form strings; should enumerate 'binance', 'bybit', 'okx'). No tool annotations (readOnlyHint, destructiveHint). Composition is strong, tools chain well (get_ticker → compute_indicators → detect_divergence). Security: no secrets in params (good). Overall: functional definitions with room for LLM-optimization and output documentation.

• Document output schemas for all tools. Example: get_ticker returns {last: number, source: 'rest'|'websocket', age_ms: number, ...}. Include field types and whether results are paginated.
• Convert 'exchange' parameter to enum: ['binance', 'bybit', 'okx']. Add similar enums for 'timeframe' if only specific values are valid (e.g., ['1m', '5m', '1h', '4h', '1d']).
• Expand descriptions to 150 - 250 chars. Add WHEN guidance: 'Use detect_divergence to find price/momentum mismatches (potential reversals). Use detect_cross for moving average or indicator crossovers (trend changes).'
• Add error handling: return structured errors with recovery hints. E.g., 'Invalid exchange: got "binance2". Valid: binance, bybit, okx. Try again with a valid exchange.'
• Add readOnlyHint: true to all tool schemas to signal idempotency and safety to agents.
