fill_taxpayer_info

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

With no annotations, the description carries full burden for behavioral disclosure. It only says 'Fill' which implies modification, but omits details on overwrite behavior, validation requirements, side effects, or required prior state (e.g., navigation). This is insufficient for a mutation tool.

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 exceptionally concise at one sentence. It efficiently lists the core fields. Minor improvement could be adding a brief note about the address subfields, but overall it's well-structured.

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 the complexity (8 parameters, nested address object, 6 required), and no output schema, the description is too sparse. It does not explain what happens after filling (e.g., form update confirmation), error scenarios, or how the nested address should be provided.

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 88%, so parameters are already well-documented in the schema. The description adds no semantic value beyond listing field categories. Baseline 3 is appropriate as it neither adds nor detracts significantly.

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 explicitly states the tool fills the taxpayer personal information section and lists the fields (name, SSN, DOB, address, occupation). This clearly distinguishes it from sibling tools like fill_1099_income or fill_w2_income.

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?

No guidance is provided on when to use this tool versus alternatives, when not to use it, or prerequisites (e.g., must be on the correct section of the form). The description lacks any strategic context for the agent.

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