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

With no annotations, the description carries the full behavioral burden and delivers little: it does not disclose pagination behavior despite page/page_size params, doesn't mention auth or platform account requirements, and doesn't explain what 'incremental' means operationally or what the freshness/latency of the feed is. The read-only nature is only inferable from 'list'.

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 naming platform, resource, and scope with zero filler. Every clause carries information; nothing is redundant or buried.

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 4-parameter tool with 0% schema coverage, no annotations, and no output schema, the description is too thin: an agent cannot determine pagination semantics, time format, return shape, or how results relate to commission/refund workflows beyond the parenthetical hint.

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% across 4 parameters, so the description must compensate and largely doesn't. It conveys only that a time range is required (mapping to start_time/end_time) while page and page_size are left entirely unexplained in both the schema and the prose, including no default values or format hints for the time strings.

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 (order list) scoped to a platform (PDD) and mode (incremental) within a time range, which is enough to distinguish it from cps_jd_orders and other siblings. The parenthetical use-case ('commission settlement & refund tracking') further clarifies intent. It falls short of 5 only because 'incremental' is left undefined (cursor vs. timestamp-based).

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 implies a usage context (commission settlement and refund tracking) but never states when to prefer this tool over cps_jd_orders, cps_pdd_convert, or other sibling order tools. No prerequisites, no exclusions, no alternative routing is given.

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