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

With no annotations provided, the description fully owns behavioral disclosure. It explicitly states that it is a stateless lookup, records no decision, and leaves no dashboard timeline trace, covering side effects and privacy implications. This goes well beyond the minimum.

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 tight sentences, front-loaded with the primary purpose and followed by essential usage context and behavioral notes. Every clause adds value with no redundancy or filler.

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 one-parameter lookup with no output schema, the description is remarkably complete: it states when to use, what it returns (statuses and caveats), the input format, and side effects. No obvious gaps remain.

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 schema already provides 100% coverage for the single parameter 'country' with 'ISO-3166 alpha-2 (e.g. US)'. The description repeats essentially the same instruction without adding new semantic detail, so it neither helps nor hurts beyond the schema baseline.

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 states a specific verb ('check') and resource ('destination country's DPDP §16 status'), clearly distinguishing it from sibling tools like japan_cross_border_status or india_sectoral_check. It also enumerates the possible statuses, making the purpose unambiguous.

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?

It gives a clear when-to-use context ('Before you transfer personal data out of India') and input instruction ('Pass the ISO-3166 alpha-2 country code'). It does not explicitly mention when not to use or name alternatives, but the country-specific nature strongly implies differentiation from sibling tools.

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