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

Annotations already declare a safe, closed-world read, and the description adds the important behavioral detail that omitting the topic returns a topic list while supplying one returns that explanation, plus the instruction to relay it conversationally one topic at a time. It does not describe anything about explanation length or formatting, but the core behavior is well disclosed.

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 trigger list is front-loaded and every clause maps to a real caller question, though the first sentence is a long run-on and the presentation instruction could be trimmed slightly.

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 single optional enum parameter with no output schema, the description covers triggers, both return modes, and how to present the result - nothing an agent needs to invoke it correctly is missing.

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% and the enum is already documented, so the baseline would be 3; the description earns more by explaining the semantic consequence of omitting vs supplying the topic, which the schema only states tersely.

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 specific verb+resource (returns explanations of Ripplewatch topics) and enumerates the exact questions it answers, which clearly separates it from action siblings like import_win_loss or get_momentum.

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 gives an explicit trigger list covering every plausible caller question (how it works, what momentum means, notifications, recent changes, team usage), so the agent knows precisely when to route here instead of guessing.

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