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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it excels. It explains the two distinct payment paths (crypto vs fiat), the exact status transitions (PAID vs PAYMENT_PENDING_CONFIRMATION), the verification mechanism (on-chain instant vs human 7-day confirmation), and the requirement for user confirmation before operation. This is exceptionally transparent.

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 compact and well-structured. It leads with the core purpose, then a critical warning, followed by method-specific behavior and a forward pointer to the subsequent tool. Every sentence earns its place with no fluff, and the use of bullets and bold/caps makes it scanable. Despite its length, it remains efficient for the complexity it covers.

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?

Given no output schema and no annotations, the description is remarkably complete. It covers prerequisites, allowed job statuses, payment-method-specific flows, outcome statuses, and the next step in the workflow. It also includes an important human-in-the-loop guardrail. There are no significant gaps for a tool with this complexity.

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?

The schema has 100% parameter coverage with descriptions for every field, providing a solid baseline. The description adds value by grouping payment_method into crypto/fiat categories and clarifying the relationship between payment_reference and payment_network for each path. While most parameter meanings are already in the schema, the description enriches the contextual semantics, so a 4 is appropriate.

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 opens with a clear verb+resource: 'Record payment for an ACCEPTED job.' It distinguishes the tool from siblings like approve_completion by explaining the full payment workflow and when the next tool should be used. The focus on job payment with status transitions makes the purpose unambiguous.

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 provides explicit usage conditions: the job must be in ACCEPTED status, and it directs the agent to check via get_job_status. It also specifies that payment details must be confirmed with the user before calling, and gives a clear alternative/next step: 'use approve_completion when done.' This fully covers when and how to use the tool versus alternatives.

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