Server has 19 well-named tools with consistent verb_noun patterns (queues_get_all, issue_get, issues_find). All tools have descriptions (avg ~80 chars, within baseline 34-392). Input schemas are present and typed for all tools. However, descriptions are terse and lack context on WHEN to use each tool or dependencies between them. Parameter descriptions are minimal, many lack format/constraint guidance. Output schemas are not explicitly documented in the code; return types are inferred from type hints. Error handling is minimal; no recovery guidance visible. Security: credentials appear to be injected server-side (good), but no explicit permission gates or audit logging visible.

• Enhance tool descriptions to include WHEN to use each tool and dependencies. E.g., 'Call queues_get_all first to discover available projects, then use queue_get_local_fields to fetch project-specific custom fields.'
• Add format/constraint guidance to all parameters. E.g., queue_id: 'Queue ID in uppercase (2-10 letters), e.g., PROJ'; issue_id: 'Format: PROJECT-123 where PROJECT is uppercase and 123 is numeric'.
• Document output schemas explicitly. Create a schema reference section or inline type definitions showing what fields each tool returns (e.g., Queue has key, name, lead; Issue has key, summary, status, assignee).
• Add error handling guidance to tool descriptions. E.g., 'Returns IssueNotFound if the issue does not exist or is not accessible. Try issues_find to search for the correct issue ID.'
• Document the Yandex Tracker Query syntax in issues_find and issues_count descriptions, or provide a link to the query language reference. Include 1-2 example queries (e.g., 'queue = PROJ AND status = Open').
