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 covered. The description adds a genuinely useful disclosure beyond them: 'This tool never reads customer bank data,' which is meaningful assurance in a banking-product context. It stops short of describing the shape of the returned content.

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 short sentences, zero filler. The content scope comes first and the privacy constraint is a tight closing line that earns its place.

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?

With no parameters, no output schema, and annotations covering the safety profile, the description gives enough to call the tool correctly. The one missing piece is how its content relates to the overlapping pricing and getting-started siblings, which an agent would need to route between them.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate. Baseline 4 applies; the description correctly avoids inventing parameter detail.

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 names a specific verb ('Explain') and enumerates the covered topics: what RPG Connecta is, audience, pricing, and canonical developer resources. It is clear what the tool does, but it does not differentiate itself from siblings like connecta_pricing and connecta_getting_started, whose scopes visibly overlap with the listed content.

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 statement of when to call this tool versus the similarly-scoped siblings connecta_pricing or connecta_getting_started. A reader is left to infer whether this is an overview entry point or a duplicate of those tools.

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