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 datacomponents but doesn't describe what 'detect' means operationally, whether this is a read-only query (implied by 'Get'), potential rate limits, authentication needs, or the format of the output. For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 purpose clearly, followed by a structured 'Args' section with parameter details. There's no wasted text, and each sentence adds value. A minor deduction for not integrating parameter semantics more seamlessly into the main description, but 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 moderate complexity (3 parameters, no output schema, no annotations), the description is partially complete. It covers the purpose and parameters well but lacks output details (e.g., what datacomponents are returned, format), behavioral context, and usage guidelines. Without annotations or output schema, the description should do more to compensate, but it meets a minimum viable level for a read-oriented tool.

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 for all three parameters: 'technique_stix_id' is explained as 'Technique STIX ID to check what datacomponents detect it', 'domain' specifies allowed values ('enterprise', 'mobile', or 'ics'), and 'include_description' clarifies its effect on output. This goes beyond the schema's basic titles and types, providing necessary context for parameter usage.

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 datacomponents that detect the given technique.' It specifies the verb ('Get'), resource ('datacomponents'), and relationship ('detect the given technique'). However, it doesn't explicitly differentiate from sibling tools like 'get_all_datacomponents' or 'get_techniques_detected_by_datacomponent', which would be needed for a score of 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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'get_all_datacomponents' (for listing all datacomponents) or 'get_techniques_detected_by_datacomponent' (for the inverse relationship), nor does it specify prerequisites or exclusions. The only implied usage is from the parameter descriptions, but this is insufficient for clear guidelines.

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