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

No annotations are provided, so the description must disclose behavioral traits. It lists actions including delete, but does not warn about irreversible deletion or other side effects. The example shows a create action but lacks details on error handling or performance impacts.

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 well-structured with clear sections (When to use, Actions, Example). It is concise, front-loaded with purpose, and every sentence adds value. No unnecessary text.

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 11 parameters and no output schema, the description could be more complete. It lacks details on return values for actions like status or list, and does not explain error scenarios or configuration nuances for anomaly detection.

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 the parameters are documented. The description adds an example that maps parameters to values, but does not elaborate on parameter meaning beyond what the schema already provides. Thus, it adds marginal 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 clearly states 'Manage cost budgets and anomaly detection.' It lists specific actions like create, update, delete, and status, making the tool's purpose precise and distinguishable from sibling tools that focus on agents, alerts, analytics, etc.

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 includes a 'When to use' section: 'To create/manage spending limits, check budget utilization, or configure cost anomaly detection.' This gives clear context, though it does not explicitly state when not to use or provide alternatives.

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