Strong foundational quality with comprehensive schema definitions and consistent naming conventions across 37 tools. Tool names uniformly follow verb_noun patterns (CreateIssue, ListIssues, UpdateIssue, etc.). All 37 tools have descriptions present, with most in the 40-150 character range. Input schemas are complete and properly typed with JSON Schema format across the board. However, parameter descriptions lack depth in many cases, most are 1-5 words rather than actionable guidance ('Issue ID' vs 'The unique identifier of the issue; can be numeric or UUID format'). Output schemas are documented via code comments but not exposed in parameter descriptions. Error handling is basic, tools return structured results but lack recovery guidance. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are visible in the code, despite clear risk classifications in the metadata. Response size protection is implemented (protectedListResult, maxResponseChars=50k) showing agent-aware design. The server demonstrates production maturity in naming, schema structure, and parameter consistency, but falls short of A-grade polish due to shallow descriptions and missing error recovery guidance.

• Expand parameter descriptions from 1-5 words to 20-80 characters with actionable format/constraint details. Example: 'Filter by status (empty string or 'all' for no filter)' → 'Issue status filter: accepted values are open, in_progress, resolved, closed, or_paused. Pass empty string or 'all' to disable filtering. Defaults to no filter.'
• Add tool annotations (readOnlyHint, destructiveHint, idempotentHint) to all tool definitions. Mark CreateIssue, UpdateIssue, AddComment as idempotent when appropriate. Mark DeleteIssue, DeleteTenant as destructiveHint=true. Mark GetIssue, ListIssues as readOnlyHint=true.
• Enhance error responses with recovery guidance. Instead of errResult(fmt.Errorf('resolving project %q: %w', input, err)), return structured error with 'Try ListProjects() to see available projects' hint.
• Add confirmation/dry-run support to destructive operations. DeleteIssue should accept optional 'confirm=true' parameter. Return a confirmation token on first call, require it on second call for actual deletion.
• Document limit constraints explicitly. Update ListIssues description to state 'limit: 1-50 (default 20; hard cap 50). When compact=false and no project specified, limited to 20 regardless of input.'
• Add permission checks visible in code. Wrap admin tools (CreateTenant, RotateAdminKey, AdminDeleteProject) in auth gates with clear error messages ('Admin role required').
• Convert string filter parameters to enums. ListIssues 'status' parameter should have enum: ['open', 'in_progress', 'resolved', 'closed', 'paused']. ListIssues 'issue_type' should have enum: ['task', 'bug', 'feature']. ListFlags 'status' should enumerate valid flag states.
