nws_app_authenticate

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

With no annotations at all, the description carries the full burden and discloses almost nothing: not what credentials are required, whether the result is a session/token that persists, whether the call is idempotent or safe to repeat, or what happens on failure. The output schema covers return shape, but the behavioral traits of an auth operation remain undocumented.

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?

A single, front-loaded sentence with no filler or redundancy. Every word earns its place, even if more content is needed.

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?

The tool is simple (no params) and has an output schema, so the description does not need to explain returns. But for an auth entry point in a large suite with a sibling nws_authenticate, at minimum the prerequisites and the distinction from that sibling should be stated; those gaps keep it at minimum-viable.

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?

The tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. Nothing in the description misrepresents or omits parameter behavior.

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 (authenticate) and a specific resource (the NWP app bridge against the configured NWP app server), which is enough to distinguish it from the generic nws_authenticate by scope. However, it never explicitly contrasts itself with the near-identical sibling nws_authenticate, leaving that differentiation implicit.

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 guidance on when to call this versus nws_authenticate or nws_app_status, all of which are plausible siblings an agent would hesitate between. There is no statement of prerequisites, ordering (e.g., must app auth precede nws_app_commit_import?), or what a failure means.

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