KusaGames exposes 11 tools via HTTP/Express but has significant quality gaps. Tool naming is reasonably clear (search, addMatch, editMatch, etc.) but descriptions are inconsistent and often lack critical context. Parameter schemas are present but incomplete, many parameters lack proper type constraints and validation guidance. Error handling is minimal; responses are generic HTTP status codes without actionable recovery guidance. The server uses a custom authentication scheme (cookie tokens) but does not validate destructive operations (delete, approve) have appropriate confirmation patterns. Output schemas are not documented in the source, making it impossible for LLMs to plan downstream tool calls. Schema quality is further hampered by missing enums for constrained fields (winner must be '1', '2', or 'D' but this is only mentioned in descriptions, not enforced in schemas). Overall, this is a functional but immature tool suite that would require significant refinement before production use.

• Document output schemas for all tools. Define response structure with typed fields and sample values. Example: search returns {matches: [{vid, p1name, p2name, p1char, p2char, winner, time}], total_count, page, page_size}.
• Convert constrained input descriptions to formal enums in schemas. Example: winner parameter should use enum: ['1', '2', 'D']. Page should have minimum: 1, maximum: 1000.
• Add confirmation/dry-run support for destructive tools. Example: add optional 'confirm' boolean parameter to deleteMatch; if false, return what would be deleted without deleting. Pair with actionable error: 'Match at timestamp 1234 queued for deletion. Call deleteMatch again with confirm=true to finalize.'
• Improve error messages with actionable recovery guidance. Replace 'No!' with 'Permission denied. Only users with approve role can call this tool.' Replace 'Couldn't find the video' with 'Video vid='abc123' not found in approved videos. Try search(tag='tournament') to list available videos.'
• Standardize parameter naming across tools. Use 'match_index' consistently instead of 'idx' vs 'orderIndex'. Document parameter relationships (e.g., 'To locate a match, provide either time (faster) or match_index (requires prior search)').
• Add scope declarations to tool descriptions. Example: 'addMatch (requires: write:video, auth as contributor)'; 'downloadMatchData (requires: admin_read, auth as Nate)'.
• Add per-tool pagination limits and guidance. Example: search() returns max 50 matches per page; use page parameter to iterate. Document that search with all filters applied is faster than without.
