Read the player's dashboard input

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

The readOnlyHint annotation already covers safety, and the description adds useful behavioral context: it returns incremental feedback since the last check and returns an empty list when there is nothing new. It does not cover permissions, rate limits, or whether reading resets the 'last checked' state.

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 front-loaded and appropriately sized. Each sentence adds value: the first describes contents, the second gives usage guidance, and the third clarifies the empty-result case.

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?

Given no parameters and no output schema, the description does a good job explaining what is returned and the empty-list behavior. It does not specify the exact item structure or whether consuming feedback clears the 'since last checked' window, leaving minor gaps.

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 has zero parameters, so parameter semantics are not a major burden. The description does not need to document inputs, and the baseline for a zero-parameter tool is met.

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 resource and scope: player activity on the dashboard since the last check, including answers, keep/drop decisions, comments, and messages. It is understandable without opening the schema, but it does not explicitly differentiate itself from siblings such as open_dashboard or dashboard_post.

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?

It implies when to use the tool by saying 'since you last checked' and explains how to act on the returned feedback, but it does not explicitly compare this tool to alternatives like open_dashboard or dashboard_post. The usage context is present but not fully explicit.

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