login_url_one_shot

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

No annotations are provided, so the description alone must disclose behavior. It conveys that the tool creates a one-shot URL and passes an optional payload, but it doesn't disclose authentication needs, expiry, side effects, or whether the URL is immediately consumed. The endpoint hint adds some context, but the behavioral burden is largely unmet.

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?

The description is very short and front-loads the core purpose and endpoint. The 'Args' line is minimal and does not waste words, though the extreme brevity contributes to under-specification elsewhere.

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?

With no annotations, a single undocumented generic parameter, and many related login/session tools in the sibling list, the description leaves important gaps: how to choose this tool, what payload content is expected, and what happens as a result beyond creating the URL. The existence of an output schema helps with return values, but not with usage context.

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 schema has 0% description coverage, so the description must compensate for the generic 'payload' object. It only says 'Optional body the panel expects,' which confirms optionality but gives no structure, examples, or hints about what keys the panel may require. This is insufficient for an agent to construct a meaningful payload.

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?

The description clearly states the action ('Create'), the resource ('one-shot panel login URL'), and the HTTP endpoint. It doesn't explicitly distinguish itself from sibling tools like login_urls_create, but the 'one-shot' qualifier and endpoint give enough specificity for basic identification.

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?

There is no guidance about when to use this tool versus login_urls_create, login_urls_list, or session_login_as. The description only states what the tool does, not the conditions under which an agent should prefer it over alternatives.

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