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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds genuine behavioral value beyond that by disclosing the analytical content returned: striking distance queries in positions 5-20 and anomalies. That is more than a restatement of annotations, though it says nothing about rate limits or result caps.

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?

Two tight sentences, zero filler. The metric list and special-content disclosure are front-loaded before the prerequisite and related-tools pointer.

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, return values need not be described, and annotations carry the safety profile. The description appropriately covers prerequisites and notable content. It could be stronger by routing between itself and the ranking/performance siblings, but nothing critical to a correct call is missing.

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% and the schema already documents the to/from date formats and the 28-day default. The description adds no parameter meaning beyond the schema, so the baseline of 3 applies.

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 (Reports) and resource (Google Search Console results) with the exact metrics returned: queries, pages, clicks, impressions, position. It differentiates itself partly from siblings by naming inspect_url and list_saved_keywords, but never mentions get_rankings or get_content_performance, which are the closest overlaps in the tool list.

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?

Gives a prerequisite ("Requires a connected Search Console property") and points at two related tools, but never states when to pick this over get_rankings or get_content_performance. The agent must infer that this is the Search Console-specific path. Context is implied rather than explicit.

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