get_threat_group

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It does state what the tool returns (aliases, description, linked techniques) and implies a read-only operation, but it omits error behavior, case sensitivity, sources, or coverage limits. This is adequate but not deeply transparent.

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 compact sentence with no filler. It front-loads the core action, clearly states the resource, and includes the identifier forms and expected return fields, making every word earn its place.

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, the core invocation requirements are covered and the expected output content is specified. However, with no output schema and several close sibling tools, the description does not clarify when to prefer this tool over alternatives or what it deliberately does not return, leaving moderate gaps.

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 100%, and the schema already documents the 'name' parameter with helpful examples like 'APT29' and 'G0016'. The description only reiterates the 'by name or ID' framing already present in the schema, so it adds no new semantic meaning beyond the 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 uses a specific verb ('Get details') and clearly identifies the resource ('MITRE ATT&CK threat group') plus the accepted identifier forms (name or ID) and returned fields. It is clear and specific, but does not explicitly differentiate itself from close siblings like get_threat_profile or search_threat_groups, so it does not earn a 5.

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?

There is no guidance on when to use this tool versus the many sibling lookup and search tools, and no exclusions or fallback conditions are stated. An agent is left to infer that exact-name/ID retrieval is intended, which is a significant gap in the sibling-rich context.

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