get_data_stats

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

With no annotations, the description sufficiently discloses the tool's behavior: it returns read-only statistics and assumes downloads were attempted at startup. No side effects are mentioned, but none are expected for a read-only 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 two sentences, front-loaded with the main purpose, and every word adds value. No wasted content.

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 tool has no parameters and an output schema exists, the description adequately covers the tool's functionality and assumptions. It could mention error conditions, but the essential context is present.

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 tool has no parameters, and the empty schema is fully covered. The description adds no additional parameter information, but none is needed.

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 tool returns statistics about downloaded MITRE ATT&CK STIX data, specifying what is included (domains, file paths, sizes, release version). It is distinct from sibling tools like 'get_stats' and other entity-specific tools.

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 usage after server startup to check downloaded data. It provides clear context for when to use the tool, though it does not explicitly exclude alternatives or compare with siblings.

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