get_rate_limit_info

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

No annotations are provided, so the description carries the full behavioral burden, yet it adds nothing beyond the name: it does not confirm this is a safe read-only operation, whether it counts against the limits it reports, or what dimension of limits (per-minute, per-tool, per-session) is returned. One clause of the description is doing all the work.

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 short sentence with no filler and the key information front-loaded. It is efficient, though so terse that it flirts with under-specification rather than being a model of tight, informative phrasing.

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?

The existence of an output schema means return values need not be described, which lowers the bar. However, with no annotations and a totally bare description, an agent gets no context on what the reported limits govern or when the information is actionable, leaving it only minimally complete.

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; the parameter baseline of 4 applies. The empty schema is self-explanatory and no param-level detail is missing.

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 ('Get') and resource ('rate limiting information'), so an agent knows exactly what it retrieves. It doesn't need to distinguish itself from siblings here since none of the listed tools overlap with rate-limit reporting, but it also offers no scope (per-user, per-tool, global), which keeps it short of a 5.

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 guidance on when to call this versus alternatives, when it matters (e.g., before issuing batches of commands), or whether the call itself consumes quota. The only 'guidance' is the implied semantics of the tool name, which is not enough for a 3.

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