list_projects_by_billing_method

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

Without annotations, the description provides the valid values for billing_method but does not disclose behavioral traits like pagination (top parameter), ordering, or authentication. The tool's read-only nature is implied but not stated.

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 a single sentence, concise and front-loaded, but it omits the top parameter explanation, which could be added without losing conciseness.

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 2-parameter tool with no schema descriptions, the description only partially covers one parameter. The top parameter is undocumented, leaving the tool incomplete. An output schema exists but its content is unknown.

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 description partially explains the billing_method parameter by listing valid values ('Hourly, Flat Fee, Percentage'), but completely ignores the top parameter (defaults to 0, no explanation). Schema coverage is 0%, so description should compensate more.

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 clearly states the action ('List projects') and the filter ('by billing method'), with specific valid values. It distinguishes from sibling tools like list_projects that list all projects.

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 usage for filtering by billing method but does not explicitly contrast with alternatives (e.g., list_projects) or provide when-not guidance.

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