Create Payment Application (Owner Invoice) For Prime Contract

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

Annotations already indicate readOnlyHint=false (write operation) and destructiveHint=false. The description adds that it returns HTTP 201 and the created object, which is mildly helpful but does not disclose other behavioral traits like authorization requirements or side effects. Minimal added value.

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 short but contains a critical error (confusing prime contract creation with payment application creation). The misleading statement makes the description harmful rather than helpful. Conciseness without accuracy is not valuable.

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 the tool's complexity (nested objects, 4 parameters, no output schema), the description fails to provide sufficient context. It inaccurately describes the tool's purpose and omits details about the required 'payment_application' structure, usage constraints, or expected behavior beyond a success response.

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 coverage is 100%, so parameters are documented. The description only restates the required parameters (prime_contract_id, project_id) without adding semantic details. It does not explain the 'payment_application' object or 'attachments' beyond what the schema provides, so no extra value.

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 incorrectly states 'Use this to create a new Prime Contracts' and 'Creates a new Prime Contracts', which contradicts the tool name and schema that clearly indicate creating a payment application (owner invoice) for an existing prime contract. This misrepresentation severely impairs clarity.

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 on when to use this tool versus alternatives. The description is misleading, suggesting it creates prime contracts rather than payment applications, which could lead to incorrect tool selection. No exclusions or when-not-to-use information is given.

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