Get Information Of A Budget Change

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, which strongly signal a safe read operation. The description adds that it returns a JSON object and mentions the API endpoint. It does not detail pagination behavior or error responses, but given the strong annotation coverage, this is acceptable and not contradictory.

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 two sentences followed by concise additional lines for required parameters and API details. It is front-loaded with the purpose and usage, with no redundant information. Every sentence adds value.

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?

The tool has no output schema, and the description vaguely says 'Returns a JSON object.' It does not explain the response structure or pagination behavior (though pagination params exist in input schema). The 'without adjustment' phrase is ambiguous. More detail on what is returned or how pagination works would improve completeness.

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 description coverage is 100%, so baseline is 3. The description lists required parameters (project_id, id) but does not add semantic meaning beyond what the schema already provides (e.g., no clarification on optional pagination parameters or format constraints).

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 verb ('Get'), specific resource ('budget change'), and scope ('full details by identifier'). It distinguishes from siblings like 'update_information_of_a_budget_change' and 'create_a_budget_change' by specifying 'without adjustment' and emphasizing it is a fetch operation.

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 explicitly says 'Use this to fetch the full details of a specific Budget records by its identifier,' which clearly indicates when to use it. However, it does not provide explicit 'when not to use' guidance or alternatives (e.g., for listing or updating), but the sibling list implies differentiation. The 'without adjustment' qualifier adds some context.

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