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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool retrieves data ('Get'), implying it's a read operation, but doesn't specify if it's paginated, rate-limited, requires authentication, or returns structured data. For a tool with zero annotation coverage, this leaves significant behavioral gaps, though it correctly avoids contradictions.

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 appropriately sized and front-loaded: the first sentence states the core purpose clearly. The 'Args' section is structured but could be more integrated. There's minimal waste, though the formatting as a code block might reduce readability slightly. Overall, it's efficient and well-organized.

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's low complexity (2 parameters, no output schema, no annotations), the description is moderately complete. It covers the purpose and parameters adequately but lacks behavioral details like response format or error handling. For a simple read tool, it's sufficient but not thorough, especially without annotations to fill 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 description coverage is 0%, so the description must compensate. It adds meaningful semantics: it explains 'domain' accepts specific values ('enterprise', 'mobile', or 'ics') and clarifies 'include_description' controls output inclusion with a default. This goes beyond the schema's basic titles and types, providing crucial context for both parameters, though it doesn't detail format or constraints exhaustively.

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's purpose: 'Get all mitigations in the MITRE ATT&CK framework'. It specifies the verb ('Get') and resource ('mitigations'), and distinguishes it from sibling tools like 'get_mitigations_mitigating_technique' by indicating it retrieves all mitigations rather than filtered ones. However, it doesn't explicitly contrast with other 'get_all_*' tools, preventing a perfect score.

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 alternatives. It doesn't mention sibling tools like 'get_mitigations_mitigating_technique' or explain scenarios where retrieving all mitigations is preferred over filtered queries. The only usage context is implied by the tool name and description, but no explicit when/when-not instructions are given.

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