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

Annotations already cover readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the safety profile is fully disclosed. The description adds that reading costs nothing, which reinforces the non-destructive and low-cost nature, and clarifies what data is read. It does not describe return format or any potential side effects, but given the annotations, the bar is lower and the description adds a useful cost/behavior detail.

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 with no extraneous words. The main purpose is front-loaded in the first sentence, and the second sentence adds a crucial cost note. Every word earns its place; it is optimally concise.

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-parameter read-only info tool with rich annotations, the description is quite complete. It lists the specific categories of information returned (rules, price, public visibility, API links). While it does not describe the output format, that is not strictly necessary for a simple info retrieval tool, and the description provides enough context for an agent to know what to expect.

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?

There are zero parameters, so the schema already provides complete coverage (100%). The description adds no parameter-specific detail because there are none. According to the rule, a baseline of 4 is appropriate for 0 params, and there is nothing missing that the description would need to compensate for.

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 'Read' with a clear resource (Speedbot rules, price, public visibility, API links), making the tool's purpose immediately clear. It does not explicitly name a sibling to differentiate from, but the specificity of what is read (rules, price, visibility, API links) is enough for an agent to understand this is a general info retrieval tool, distinct from actions like speedbot_send or speedbot_unlock_info.

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 gives a practical hint that reading costs nothing, implying it is safe and cheap to call. However, it does not provide explicit guidance on when to use this tool versus alternatives (e.g., speedbot_read or speedbot_unlock_info). The 'costs nothing' hint is a usage factor but lacks direct comparison to siblings.

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