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

No annotations are present, so the description must carry the burden. It says 'Returns' which implies a non-destructive retrieval, but it doesn't explicitly state that it has no other side effects, doesn't mention authentication requirements, and doesn't describe rate limits or other costs beyond 'FREE'. The 'FREE' and prerequisite conditions add context but leave some behavioral traits unspoken.

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 three short sentences, each contributing useful information: what is returned, the cost, and the recommended usage. The main purpose is front-loaded, and there is no redundancy or filler content.

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?

For a simple one-parameter tool with no output schema, the description provides enough high-level context: that it returns config and readiness, what that readiness means, and how/when to use it. Output field details (e.g., exact structure of settings) are absent, but for a single-param GET tool this is not a critical miss; a bit more detail on the expected response shape would make it fully complete.

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% – the single parameter projectId has a thorough description including how to obtain it, format, and examples. The description text itself adds nothing more about the parameter, so the baseline of 3 is appropriate since the schema does all the work.

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?

States a specific verb ('Returns') and exact resource ('one project's settings'), plus the readiness condition ('configured enough to generate content'), which is unique and distinguishable. Mentions the sibling seo.content.generate directly, making the role of this tool clear relative to siblings.

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?

Explicitly instructs to 'Use this before seo.content.generate', names the alternative, and explains the benefit ('avoid starting a run that will immediately fail'). The FREE indicator adds incidental guidance. This is exactly the when-to-use vs. alternative guidance requested.

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