group_threat_actor

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

No annotations are provided, so the description is the sole source of behavioral info. It states the tool returns structured assessment, regulation refs, and recommended actions, but does not disclose whether the operation is read-only, requires special permissions, or has side effects. The lack of transparency leaves the agent uncertain about impact.

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 concise, using three lines to cover purpose, args, and returns. It is efficiently structured, though the initial fragment is slightly awkward. Every sentence adds some information, but the first sentence could be clearer.

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 description lacks differentiation from sibling tools and fails to explain how this tool fits into a workflow. With two parameters, an output schema, and related tools, the description should provide more context on use cases and relationships, but it is incomplete.

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 has 0% description coverage, but the description adds some meaning: 'query: Optional query parameter (regulation ref, identifier, or input data)' and 'api_key: Optional MEOK API key for Pro+ tier features.' While this clarifies parameter purpose, the descriptions are still vague (e.g., 'input data' is broad). It partially compensates for the schema gap but not fully.

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 'Threat actor groups (G-codes) using a technique' is a fragment that lacks a clear verb or action. It suggests the tool retrieves groups by technique, but does not definitively state what the tool does. The title and name are vague, and the purpose is not explicitly stated, making it difficult for an agent to understand the tool's primary function.

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 provides no guidance on when to use this tool versus its siblings (list_tactics, map_incident, mitigation_lookup, query_technique). There are no explicit conditions, exclusions, or alternatives mentioned, leaving the agent without context to decide between tools.

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