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

Annotations declare destructiveHint=true and readOnlyHint=false, but the description says nothing about mutation, side effects, rate limits, or auth needs. The phrase 'provide you with an overview' passively implies retrieval without confirming or clarifying the annotated write/destructive profile, so the description adds no behavioral context beyond the structured fields.

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. It is efficiently structured, though the brevity edges toward under-specification rather than tight conciseness.

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 tool with a complex nested array-of-objects body and many filtering options, the description omits when-to-use, parameter shape, and any behavioral nuance. The presence of an output schema excuses it from explaining returns, but it remains too thin given the input complexity.

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?

Top-level schema description coverage is 0% — the sole 'body' parameter is undocumented at that level (though nested items are richly described). The description contributes no parameter meaning (e.g., that body is an array of per-keyword task objects) and so fails to compensate for the coverage gap.

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?

The description states a resource and action ('overview of citation data available for the target keyword'), which is more specific than the title alone. However, it does not distinguish this tool from siblings like post_dataforseo_content_search_live or post_dataforseo_content_sentiment_analysis_live, leaving the agent to infer what makes a 'summary' unique.

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 endpoint versus the many sibling content/analysis tools, nor any prerequisites or exclusions. The agent gets no routing help at all.

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