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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is clear. The description adds useful behavioral context about the output being a side-by-side table of verified facts with specific fields and no winner, though it does not discuss auth or rate limits.

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?

The description is three compact sentences with the use case front-loaded. Every sentence contributes: the trigger condition, the output form, and the 'facts only; no winner' boundary.

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 low-complexity, single-parameter read-only tool with full schema coverage and annotations, the description is complete enough. It covers when to use it, what tool set it applies to, and what the returned table contains, so an agent does not need an output schema to call it 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%, so the schema already documents the single 'tools' array parameter, including minItems and maxItems. The description adds value by clarifying that these are names or slugs of sales or GTM AI connectors and by giving example pairs like HubSpot vs Salesforce.

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 uses the specific verb 'compares' with the resource '2 to 5 sales or GTM tools' AI connectors' and gives concrete examples. It clearly differentiates this side-by-side comparison from sibling tools like get_tool or search_tools by emphasizing multi-tool comparison.

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?

It explicitly says 'Use when someone compares 2 to 5 sales or GTM tools' AI connectors' and provides example comparisons. However, it does not name alternatives such as get_tool for single-tool lookups or state when not to use this tool, leaving that inference to the agent.

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