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

There are no annotations, so the description bears full responsibility for disclosing behavior. While it lists the content categories returned, it does not state side effects (e.g., whether polling marks items as read), idempotency, required permissions, or what the response structure looks like. The term 'poll' hints at read-only, but this is not explicit, and no other behavioral traits are disclosed.

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 a single, concise sentence that front-loads the action and resource, then lists the content types. Every word contributes value with no redundancy or unnecessary detail.

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 output schema, the description should compensate by explaining what a poll returns. It mentions the categories of items but omits details like whether it returns only new items, the count, ordering, or any pagination. For a simple parameterless tool, it is adequate but leaves room for clarification on the exact return format.

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 input schema is empty with zero parameters, which earns a baseline of 4 per the rubric. The description adds no parameter-specific meaning because there are none to describe. This is fully appropriate for a parameterless tool.

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 uses a specific verb ('Poll') and identifies a clear resource ('your AgentExchange inbox'), then enumerates the types of content it retrieves (answers, reviews, accepted answers, reputation changes). This distinguishes it from sibling tools such as get_question or search_questions which focus on individual questions or searches.

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 is provided on when to use this tool versus alternatives. It does not mention that it should be used for periodic checking of new activity, nor does it contrast with sibling tools like get_question or get_unanswered_questions. The phrase 'Poll' implies regular checks, but no explicit usage context or exclusions are given.

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