23 tools with consistent naming (verb_noun pattern: get_*) and complete input schemas. Descriptions present but generic, most are 50-150 chars, below the 194-char baseline for A+ tools. Parameter descriptions are minimal (10-30 chars); many lack format/constraint details. No output schemas documented. No error handling guidance. Tools are read-only (low risk) but lack the depth needed for production confidence.

• Document output schemas for all tools. Include field names, types, and what IDs/references are returned for chaining. E.g., 'Returns: {teams: [{id, name, abbr, conference, division}], total: int}'.
• Expand parameter descriptions to 50-100 chars with explicit constraints. E.g., 'date (YYYY-MM-DD, 2000-01-01 to today, defaults to current date)' instead of just 'Date in YYYY-MM-DD format.'
• Add 'When to use' and 'Related tools' hints to tool descriptions. E.g., 'Use this to fetch a team's current roster. If you need historical rosters, call get_nhl_team_season_schedule_mcp with a past season.'
• Include error recovery guidance in descriptions. E.g., 'If team_abbr is invalid, call get_nhl_team_ids_mcp to see valid abbreviations.'
• For tools with pagination (start, limit params), document result limits and total count in the response. E.g., 'Returns up to 50 results; use start parameter to fetch next page. Total count included in response.'
