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

Annotations indicate readOnlyHint=false and openWorldHint=true, so the description correctly implies a write/append action. It adds context about no auth required and the voluntary nature, but it does not disclose any side effects, whether the report is updateable, or what happens on repeat submissions. This is acceptable given annotations but not deeply transparent.

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 concise at two sentences and front-loads the core action. The second sentence adds motivational context that is somewhat valuable for usage guidance, but could be trimmed. Overall, it is appropriately sized and structured.

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 an output schema present and complete parameter descriptions, the description covers the essential context: what to report, when, and that no auth is needed. It does not need to explain return values since the output schema exists. The tool is simple enough that this level of detail is sufficient.

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 coverage is 100% and parameter descriptions are clear and detailed (e.g., agent_id flow, article_slugs format). The description itself adds no new parameter information, so it meets the baseline of 3 but does not elevate further.

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 ('voluntarily declare') and the resource ('which TAT articles you used'), making the tool's purpose immediately obvious. It also distinguishes itself from sibling tools by focusing on reporting usage rather than retrieving articles or stats.

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?

The description provides clear context: use this tool after producing output to disclose article usage, with the benefit of being recognized as a verified consumer. It also clarifies that no auth is required. It does not explicitly name alternatives or exclusions, but the use case is reasonably implied.

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