get_trustmrr_rankings

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

No annotations are provided, so the description carries the full burden. It states the tool fetches rankings but does not disclose behavioral traits such as caching behavior (though use_cache parameter exists), rate limits, data freshness, or whether results are sorted. The description is insufficient for a tool without annotations.

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 extremely concise with two sentences. The first sentence is action-oriented stating the core functionality, and the second adds context. Every word earns its place with no redundancy.

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 the tool has no output schema and no annotations, the description is incomplete. It does not explain the output format, pagination behavior, sorting order, or caching implications. An agent would lack key details to effectively use the tool.

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% with descriptions for both parameters (limit, use_cache). The description adds no additional meaning beyond what the schema already provides. According to guidelines, baseline is 3 when coverage is high, and no extra value is contributed.

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 clearly states the verb ('Get') and resource ('MRR/revenue rankings from TrustMRR'), and adds context about the data being publicly shared revenue from indie projects. However, it does not explicitly distinguish it from similar sibling tools like get_indiehackers_income_reports, which also provides revenue data.

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?

The description provides no guidance on when to use this tool versus alternatives. It neither states when it is appropriate nor mentions cases when other tools should be preferred. An agent would have to infer usage solely from the tool name and description.

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