get_gstin_filing_preference

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

Since no annotations are provided, the description carries the full burden. It does disclose the key behavioral output: the filing preference is reported quarterly across the financial year. However, it doesn't mention possible response values, data freshness, authorization requirements, or edge cases such as invalid GSTINs or years with no filing data.

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 a single concise sentence with no wasted words. It communicates the core query and the quarterly granularity up front, making it easy for an agent to scan and understand.

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 two-parameter lookup with no output schema or nested objects, the description provides enough context: it identifies the entity, the year scope, and the quarterly output dimension. Minor gaps remain around exact returned values and error behavior, but these are not critical for an initial tool selection decision.

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 already documents both parameters well, with format patterns and examples, so schema coverage is 100%. The description itself does not add parameter-level detail, but it does clarify that the response is organized by quarter, which relates to the financial_year parameter. This matches the baseline for fully documented schemas.

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 expresses the tool's purpose: reporting whether a taxpayer files Monthly or Quarterly (QRMP) for each quarter of a financial year. It names the resource (GSTIN filing preference) and the query scope, though it doesn't explicitly contrast with sibling tools like get_gstin_returns or get_gstin_compliance.

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 implies when to use the tool: when you need a taxpayer's filing frequency preference for a given GSTIN and financial year. It provides no explicit guidance about when not to use it or which sibling tool would be more appropriate for related needs such as returns or compliance.

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