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

Annotations already mark the operation read-only and non-destructive; the description adds useful behavioral detail: the snapshot is 'public' and 'bounded', setting expectations about access and depth. No contradiction with 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?

A single front-loaded sentence with no filler; every word adds semantic value.

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 simple two-parameter read tool, the description plus annotations cover the safety profile and core behavior. It lacks an explicit statement of return shape, but no output schema exists and the order-book return value is largely inferable from the tool name.

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?

With 0% schema description coverage, the tool description must compensate for parameter meaning. It hints at 'one symbol' and 'bounded' to map to symbol and limit, but it does not explicitly describe limit's role, optionality, or format; the schema's min/max carry part of that burden.

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?

Description uses a specific verb ('Read') with a clear resource ('public order book snapshot') and scope ('for one symbol'), immediately distinguishing it from sibling tools like get_ticker or get_candles. The word 'bounded' also foreshadows the limit parameter.

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 clearly states the context: a public, per-symbol order book read, which tells an agent when this tool is relevant. It doesn't name explicit alternatives or exclusions, but no sibling tool competes for the order-book use case, so the omission is minor.

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