Three tools with basic descriptions but significant schema and parameter documentation gaps. connect_reader and set_log_level lack input schema visibility; get_log has a detailed schema but descriptions are minimal (under 100 chars). No tool descriptions explain WHEN to use them, prerequisites, or what happens on error. Parameter descriptions exist but lack constraints (enums, ranges, formats). No output schemas documented. Error handling guidance absent. Naming is verb-forward (good), but descriptions do not meet the 10-1024 char baseline for LLM optimization (pattern:tool-description).

• Expand tool descriptions to 150-250 chars. Example for get_log: 'Retrieve log entries from the connected screen reader. Supports filtering by level, time window, and text content. Use this to debug reader behavior or audit recent activity. Returns paginated results with timestamps and severity levels.'
• Add enum constraints to level parameters: minLevel and level in set_log_level should declare enum: ['debug', 'info', 'warning', 'error']. Document in description: 'The log level to set (one of: debug, info, warning, error).'
• Document output schemas for all tools. Example for get_log: 'Returns {entries: [{id, timestamp, level, message, source}], total_count, next_cursor}'. Include in tool description or as a separate schema field.
• Add bounds to numeric parameters. Example: windows (1-100, default 10), maxEntries (1-1000, default 100), lastSeconds (1-86400). State in descriptions: 'Number of log windows to retrieve (1-100, default 10).'
• Add error handling guidance to descriptions. Example: 'If reader is not connected, returns error 'Reader not connected. Call connect_reader first.' If level is invalid, returns 'Invalid level: must be one of debug, info, warning, error.'

Inferred effective spec: 2025-06-18+.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
