The server provides 18 tools covering Kubernetes, Helm, Kustomize, and documentation search. All tools have basic descriptions and input schemas are visible in the code. However, several critical quality issues emerge: (1) Schema completeness, while types are declared, many parameters lack detailed constraints, validation rules, or examples in descriptions; (2) Description brevity, most descriptions are 50-150 chars, which is below the ideal range of 50-200 chars for LLM optimization, and they lack actionable guidance on when to use each tool; (3) Parameter descriptions are sparse, many parameters have minimal or generic descriptions (e.g., 'Pod name', 'Resource name'); (4) No output schemas documented, tools declare they return data but don't describe the response structure; (5) Error handling guidance is absent, no recovery instructions or categorization of errors; (6) No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite having both read-only and write tools; (7) Composition issues, tools like kubectl_get, kubectl_describe, and kubectl_logs have overlapping concerns but no clear guidance on which to use when. The server is functional but lacks the production-grade polish expected for a 70+ score.

• Document output schemas for all tools. Add a 'Returns' section to each tool description listing the fields in the response. E.g., 'Returns: {results: [{title, url, snippet, source}], total_count}'. This enables LLMs to understand what data flows between tools.
• Expand parameter descriptions to 50-200 characters, including WHAT the parameter controls, WHEN it's needed, and FORMAT rules. E.g., instead of 'Pod name', write 'Pod name in the format pod-name or pod-prefix-*. Leave empty to list all pods in the namespace.'
• Add tool annotations to every tool: readOnlyHint=true for all read-only tools, destructiveHint=true for tilt_trigger, idempotentHint=true for all kubectl and helm query tools. Use the toolAnnotations capability map in the server's initialization response.
• Add error handling guidance to critical tools. E.g., for kubectl_get: 'If the resource is not found, the tool returns 404. Try list_resources_in_namespace to verify the resource exists. If the namespace is wrong, the tool returns 403. Verify with helm_list_releases or kubectl describe namespace.'
• Clarify kubectl tool roles in descriptions: kubectl_get returns tabular status; kubectl_describe returns detailed event logs and conditions; kubectl_logs returns application stdout/stderr. Add examples showing typical output for each.
• Standardize tool naming: prefix Kubernetes tools consistently (kubectl_get, kubectl_describe, kubectl_logs vs. kustomize_build), Helm tools (helm_list_releases, helm_get_values), and documentation tools (docs_search, docs_get, docs_list_topics or keep search_docs but prefix others). Consistency reduces LLM confusion.
