Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

TDQS
Scored across 13 tools
Each tool targets a distinct resource and action: AI generation/embeddings/chat, key lifecycle operations, and z/OS Connect service interactions. Even within similar actions like list_models vs list_keys, the domains are clearly separated by prefixes and descriptions, leaving no ambiguity.
The naming uses consistent lowercase snake_case with clear subservice prefixes (watsonx_, key_protect_, zos_connect_). However, verb placement is not uniform: some tools start with a verb (watsonx_generate, key_protect_list_keys) while others are noun-only (watsonx_embeddings). This minor inconsistency is easy to adapt to.
With 13 tools spanning three related enterprise AI and mainframe domains, the count is well within the ideal range. Each tool handles a distinct operation without redundancy or excessive granularity, making the set easy to learn and use.
Each sub-domain has solid coverage: watsonx generation, chat, embeddings, and model listing; key management covers CRUD plus wrap/unwrap; z/OS Connect supports listing, fetching specs, and calling services. Minor gaps like key rotation or service deployment exist, but the core workflows are fully supported.
