TDQS
Scored across 6 tools
Each tool targets a clearly distinct operation: arithmetic, file reading, note searching, URL fetching, security inspection, and note writing. No overlap in purpose.
Five tools follow verb_noun pattern (read_file, query_notes, fetch_url, inspect_tool_metadata, write_note). The calculator tool uses a noun only, which is a minor deviation but still readable.
Six tools is well-scoped for a security-focused lab server. Each tool earns its place without bloat or deficiency.
Covers core operations for a guarded lab environment: read, write, search notes, fetch URLs, compute, and inspect tool metadata. Missing file write or note deletion, but these are likely intentional safety constraints.
