TDQS

A4.4/5.0

Scored 2026-09-11 06:04 across 5 tools

Disambiguation5/5

Each tool targets a distinct artifact (dependencies, notes, values, versions, chart search), and descriptions explicitly differentiate them, including guidance like using get_versions to confirm existence before get_values. No functional overlap.

Naming Consistency5/5

All tools follow a consistent get_*/search_* verb_noun snake_case pattern, predictable and readable throughout.

Tool Count5/5

Five tools is well-scoped for read-only Helm chart inspection, each covering a distinct piece of the inspection workflow with no redundant tools.

Completeness4/5

Covers chart discovery, version listing, values/schema, dependencies, and notes, providing a complete read-oriented surface. Missing write operations (install, template render, lint) but those may be out of scope for this MCP server.
