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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false. The description adds useful access context beyond those annotations: the content is public and requires no sign-in. It does not contradict any annotation and meaningfully clarifies the tool's access profile.

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 with the tool's purpose, then uses a concise colon-led list to enumerate the covered topics, ending with a short access note. Every clause adds useful scope information with no filler.

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 parameters, four safety annotations, and an output schema present, the description only needs to convey what the tool explains and how it can be accessed. It does both, so an agent has enough context to call it correctly.

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 parameter semantics do not need description-level explanation. Per the rubric, a zero-parameter tool receives a baseline of 4.

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 states a specific informational purpose and enumerates exactly what content is covered: setup steps, revenue sources, post platforms, creator decisions, and product requirements. This makes the tool's scope clear, though it does not explicitly distinguish itself from siblings like about_whichpost or get_faq.

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 only usage guidance is that the information is public and needs no sign-in. There is no explicit statement of when to choose this tool over alternatives such as about_whichpost, get_faq, or privacy_and_security, leaving selection between informational siblings to inference.

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