futures_contract_info_dce

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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, which cover safety. The description adds the source URL and return type (pandas DataFrame), but no further behavioral details such as data freshness, pagination, or columns, which is acceptable for a simple parameterless query.

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, consisting of a source URL and a return type line. It is efficient and front-loaded, though the format is somewhat technical and could be more readable for an agent.

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 tool with annotations covering safety, the description conveys the data source, the category (trading parameters contract info), and the return type. While it does not enumerate columns, the simplicity of the tool makes this largely 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?

With zero parameters, the baseline is 4. The description confirms no inputs are needed and returns a DataFrame, which is sufficient for parameterless invocation.

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 identifies the resource (DCE contract info under trading parameters) and names the exchange in the title, distinguishing it from sibling tools for other exchanges. Although it lacks an explicit imperative verb like 'list' or 'get', the ':return:' line and URL make the retrieval purpose evident.

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?

No guidance is provided about when to use this tool versus alternatives. The name and URL imply DCE-specific usage, but there is no explicit mention of when to choose this over futures_contract_info_cffex, futures_contract_info_czce, etc.

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