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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, covering the safety profile. The description adds modestly useful behavior (default is the current trading day, return is a pandas.DataFrame) but says nothing about source latency, coverage limits, or data freshness.

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?

Compact docstring form with the exchange and resource front-loaded, followed by param, type, return, and rtype. The raw source URL is marginal noise but not enough to hurt readability.

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 one-parameter, annotation-rich data fetch, the definition supplies purpose, parameter format/default, and return type. An output schema is absent but rtype (pandas.DataFrame) compensates adequately; nothing essential for correct invocation 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 description coverage is 0%, so the description must carry the single parameter, and it does: accepted formats (YYYY-MM-DD, YYYYMMDD, or datetime.date) plus the default-is-current-trading-day behavior. This meaningfully exceeds what the bare string schema conveys.

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?

States a specific resource (settlement parameters, 结算参数) scoped to a named exchange (郑州商品交易所/CZCE). It is clearly distinguishable from the futures_settle_cffex/gfex/ine/shfe siblings via the exchange qualifier, though the description never says so explicitly.

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 statement of when to use this versus the other exchange-specific settlement tools or futures_settle. The exchange-specific naming is the only routing signal, and the description adds no exclusions or conditions.

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