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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds useful response context by stating each answer carries an answer_id consumed by toggle_answer_visibility and tag_answer, but says nothing about pagination behaviour or result shape beyond that one field.

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 with the core purpose front-loaded and no filler. It could be even leaner given how much the schema already carries, but nothing is wasted.

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 read-only list tool with full annotation coverage and complete parameter documentation, this is minimally adequate. With no output schema, a little more on the returned structure and how to page through large answer sets would help, but the essential calling information is present.

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 11 parameters (including filters, sort, limit/offset, and link-scoping fields) are all documented in the schema. The description adds no parameter meaning beyond what the schema already provides, 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 + resource: returns a list of respondent answers (submissions) for a quiz. The purpose is unambiguous, but it never differentiates itself from adjacent siblings such as get_answer_tags, get_answer_extra_field_values, or the export_answers_* family, which also surface answer data.

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?

No when-to-use, when-not-to-use, or alternative-tool guidance is given. The mention of answer_id feeding toggle_answer_visibility and tag_answer hints at downstream workflows, but that is a data-flow note rather than selection guidance against the many sibling answer/report tools.

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