Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full load; it does usefully disclose that secrets are redacted in the response, which is genuine behavioral context an agent would otherwise guess wrong about. However it never states explicitly that this is a non-destructive read, nor anything about permissions or response shape.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One short front-loaded sentence with no filler; every word earns its place. It's borderline under-specified rather than padded, so it loses a point only because brevity here comes at the cost of guidance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-parameter list tool with a fully documented schema, the description covers the core action and one important output caveat (redaction). Without an output schema or annotations, though, an agent still lacks any sense of return shape, pagination, or error conditions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both device_id and vdom are already documented in the schema. The description adds no extra meaning such as whether vdom is required for multi-VDOM devices or what happens if it's omitted. Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (List) and resource (TACACS+ servers), which cleanly separates it from the auth-server siblings (list_radius_servers, list_ldap_servers, list_saml_servers). It doesn't mention the device scope that the required device_id implies, but the resource name alone is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No indication of when to use this versus the other AAA server listings, no prerequisites (e.g., device must be reachable/added), and no conditions under which it would fail or be the wrong choice. The agent must infer everything from the name.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
