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

Annotations already declare readOnly, idempotent, closed-world, non-destructive, so the safety profile is covered. The description adds real behavior the annotations cannot: the list is authoritative and must be copied verbatim rather than reconstructed, which tells the agent this is a source-of-truth fetch. No mention of freshness/auth requirements, so not a 5.

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 sentences, both front-loaded: the return contents first, then the required usage constraint. Every clause carries information; the em-dash enumeration and the 'never recall, guess or invent' rule both earn their space.

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 one-optional-parameter read with no output schema, the description covers what is returned, why it matters, and the pageId consequence. It does not describe the shape of the entries (plain text vs structured records) or whether the list is account-wide versus page-scoped, which would help an agent paste results 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?

Schema coverage is 100% and the single pageId parameter is already documented with the same consequence ('without it the list omits where this page actually sends its form submissions'). The description reinforces rather than extends the schema, so the baseline 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 and resource ('Returns the current list of parties that process form submissions') and enumerates the exact contents (Pageree, infrastructure sub-processors, delivery destination). No sibling tool returns this data, and the enumeration makes the resource unmistakable.

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 says the tool is 'REQUIRED when writing a privacy policy' and prescribes how to use the results ('paste the entries verbatim and never recall, guess or invent them'), which is strong when-to-use guidance. It stops short of naming alternatives or exclusion cases, e.g. pointing to get_skill_privacy_and_consent for the broader policy workflow.

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