Five tools with minimal descriptions (10-50 chars) and incomplete schemas. Three tools (current_time, mem0_memory, rss) have empty input schemas {}. Two NBA tools accept only a date parameter with basic type info. No output schemas documented. No error handling guidance. No parameter validation constraints (enums, ranges, patterns). Tool names are reasonable (verb_noun style) but descriptions lack context on WHEN to use each tool, WHAT they return, and dependencies. Hooks file shows good defensive programming (date normalization, dedup, truncation) but this is implementation detail, not schema quality.

• Add output schemas to all tools. Document return type (object/array/string), key fields, and example structure. E.g., nba_get_scoreboard should return {games: [{team_a, team_b, score_a, score_b, game_id}], date, total_count}.
• Expand tool descriptions to 50-200 chars. Include WHEN to use (e.g., 'Call this to fetch NBA scores for a specific date; use nba_find_game if you need a single game'), WHAT it returns, and any prerequisites. Example: 'Fetches NBA scoreboard for a given date (YYYYMMDD format). Returns list of games with scores, teams, and game IDs. Use nba_find_game to filter by specific teams.'
• Add enum constraints to rss 'action' parameter. Define valid actions (e.g., 'fetch', 'parse', 'validate') and document what each does. Replace free-form string with constrained choice.
• Document mem0_memory input schema explicitly. If it accepts {action, data, query} parameters, add them to the schema with types and descriptions. If it's a stateful service, clarify how to invoke it (e.g., 'action: store|retrieve, data: {...}, query: string').
• Add error handling guidance to all tools. E.g., 'If date is invalid, returns error with format hint. If no games found, returns empty list with message. If API is down, returns timeout error, retry after 30s.' Per pattern:recovery-guide.
