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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds only a vague content note ('metadata + budgetary resources') and says nothing about how the account is resolved, what happens with an invalid code, or any other behavior beyond the structured fields.

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?

A single front-loaded sentence with zero filler. It states the resource and payload categories immediately and does not bury the purpose in preamble.

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 is simple (one required parameter) and has both annotations and an output schema, so return-value explanation is not needed. However, the critical gap remains the undocumented account_code format and the lack of differentiation from sibling federal-account tools, which the description should have closed given 0% schema coverage.

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 0% for the single required parameter, account_code, which has no title, format, or example in the schema. The description does not compensate by explaining what an account code looks like or where to obtain it (e.g., from list_federal_accounts), leaving the agent without the information needed to form a valid call.

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?

Names a specific verb (get) and resource (an individual federal account) and adds what the payload contains: metadata plus budgetary resources. It does not, however, distinguish this tool from close siblings like get_federal_account_fy_snapshot or get_federal_account_program_activities, so an agent cannot tell which account-scoped tool to pick from the description alone.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as list_federal_accounts for discovery or get_federal_account_fy_snapshot for snapshot data. The agent is left to infer routing from the tool name.

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