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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only 'Paged' plus the raw endpoint; it says nothing about auth requirements, rate limits, ordering, or default page size behavior.

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?

Three short fragments, front-loaded with the resource definition and zero filler. The trailing 'GET /receive_payments' is marginal but harmless; the telegraphic style stops just short of perfectly structured prose.

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-param paged list with annotations covering safety, this is adequate. However, with no output schema, the description gives no hint of what a payment record contains, leaving the agent to guess at the response shape.

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?

Both parameters are fully documented in the schema (100% coverage), including next_page guidance and the 1-100 page_size bound. The description adds no meaning beyond the schema, so the baseline of 3 applies.

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 names the specific resource (customer payments received against sales invoices) and implies the list verb through 'Paged'. The 'customer ... against sales invoices' phrasing distinguishes it reasonably from jurnal_list_purchase_payments, though it never names that sibling 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?

Usage is only implied: an agent can infer it lists received customer payments, but there is no explicit 'use this when...' or exclusion against jurnal_list_purchase_payments, jurnal_get_sales_invoice, or the get_* payment siblings.

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