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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered structurally. The description adds no behavioral context of its own — no note about result ordering, pagination behavior relative to the 'all' claim, or what an analysis record contains.

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?

A single front-loaded sentence with no filler is structurally clean, but it is under-specified rather than genuinely concise. The claim of 'all' results without addressing the limit parameter costs it a point.

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 read-only listing tool with full schema coverage and no output schema, the description is minimally adequate. However, it leaves open how analyses relate to audits and how pagination/limit affects the 'all' framing, which an agent would need when choosing among the many list_* siblings.

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 description coverage is 100%, with both site_id and limit (default 25) documented in the schema itself, so the baseline is 3. The description contributes nothing beyond the schema, and the word 'all' arguably sits in mild tension with the unmentioned limit cap.

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 (list) and resource (SEO analyses) scoped to a site, so the core operation is unambiguous. It does not differentiate itself from nearby siblings such as get_analysis or list_audits, leaving the agent to infer which listing/retrieval tool applies.

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?

There is no guidance on when to use this versus get_analysis (single analysis) or list_audits, and no prerequisites or exclusions are stated. The agent must infer usage from the name alone.

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