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

No annotations provided, so description must cover behavioral traits. It discloses token validity (4 minutes) and that the call is lazy-loaded, but does not mention rate limits, side effects, or authorization requirements. Adequate but could be more comprehensive.

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?

Description is a single cohesive paragraph with a clear heading, functional explanation, and use-case list. Efficient but slightly verbose in the use-case part; could be slightly more concise.

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?

Given low complexity (1 parameter, no output schema, no annotations), the description fully covers the tool's purpose, input, output (AI answer text, source URLs, subtopic sections), and usage context (follow-up call with token validity). Complete for agent decision-making.

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?

Input schema has 100% coverage (one parameter with description). Description mostly reinforces the schema (token from aiOverview block, 4-minute validity). No additional semantic richness beyond schema, so baseline 3.

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?

Description clearly states 'Get AI Overview Results' and explains it fetches lazy-loaded AI Overview block via pageToken, listing specific return values (AI-generated answer text, source URLs, subtopic sections). It distinguishes from sibling tools like other Google SERP tools by specifying it's a follow-up call for AI Overview.

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?

Description explicitly states 'Use as a follow-up call to Google SERP for tracking AI citations in SEO, fact-checking answers against sources, and LLM retrieval pipelines'. Provides clear context and purpose, though no explicit when-not or alternatives are mentioned.

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