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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds the useful detail that the result is a list of platforms with method hashes. However, it does not disclose other behavioral aspects such as return format, ordering, or whether the list reflects live availability.

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 sentence with no filler. The verb and object are front-loaded, and every word contributes to meaning.

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 no-required-parameter read-only list tool, the description covers the main need: what is being listed and what the entries include. However, with no output schema and no comparison to sibling platform-oriented tools, a little more context could improve completeness.

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 input schema only contains an optional generic 'params' catch-all, and the description adds no parameter-level semantics beyond that. With 100% schema description coverage, the baseline of 3 is appropriate; the schema already explains the only available input.

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 a clear verb ('List'), identifies the resource ('supported payment platforms from Peerlytics'), and indicates the output includes 'method hashes.' It is specific and understandable, but it does not explicitly distinguish itself from sibling tools like peer_config_platforms or peer_market_meta_currencies.

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 guidance is provided on when to use this tool versus alternatives such as peer_config_platforms or peer_market_meta_currencies. The read-only annotations imply it is informational, but no explicit conditions, exclusions, or decision criteria are given.

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