Delete Budget Modification

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

The description explicitly states the deletion is permanent and cannot be undone, aligning with the destructiveHint annotation. It also adds the condition about Budget Changes, which is useful behavioral context beyond the annotation.

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 somewhat repetitive (e.g., 'This cannot be undone' appears multiple times) and includes extra details like the full endpoint URL that may not be necessary. It is front-loaded but could be more concise.

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 delete tool with comprehensive annotations and schema, the description covers the key aspects: what it does, condition for use, deprecation, and permanence. It lacks details on return values, but this is acceptable for a delete operation.

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 input schema has 100% coverage with clear descriptions for both parameters. The description merely repeats the parameter names without adding new semantics, so it meets the baseline but adds 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 clearly states the tool deletes a Budget Modification, specifies the condition (only if Budget Changes are not enabled), and mentions deprecation. It distinguishes the action from other budget-related tools by including the endpoint and API context.

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 a clear condition for use ('only if Budget Changes are not enabled') and informs about deprecation, suggesting users should consider the new API. However, it does not explicitly list alternatives or when not to use, leaving some ambiguity among sibling tools.

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