Critical gaps across all dimensions. Tool definitions exist but lack essential structure. No visible input schemas in source code, cannot verify parameter types, constraints, or descriptions. Tool descriptions are present but generic (10-50 chars), providing minimal LLM guidance. No evidence of output schema documentation. Error handling and recovery guidance absent. Naming follows verb_noun convention but lacks clarity on parameter expectations. This server is in the F/D range, barely functional for agent use.

• Add explicit JSON Schema definitions for all tool inputs. Include type, description, enum constraints, and min/max for every parameter. Reference: pattern:constrained-input.
• Expand tool descriptions to 100-200 characters. State WHAT the tool does, WHEN to use it (vs similar tools), and any prerequisites. Example: 'Search Grafana dashboards by title or tag. Use this to find existing dashboards before creating new ones. Returns dashboard ID, title, and URL for chaining to update_dashboard.'
• Document output schemas with field names, types, and descriptions. Include pagination info (limit, offset, total_count) and IDs needed for downstream tool calls.
• Add error handling guidance: categorize errors as retryable (rate limit, timeout) vs user-fixable (invalid parameter) vs fatal (permission denied). Return actionable messages like 'Invalid status: got "pending", must be one of: open, in_progress, resolved, closed'.
• For WRITE tools (incident, dashboard, oncall, sift, admin), add a dry_run parameter or confirmation step. Example: 'Set dry_run=true to preview changes without executing. Confirm with dry_run=false to apply.'

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
