get_subtechniques_of_technique

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

No annotations are provided, so the description carries the full burden. It indicates a read operation ('Get') and describes the return structure fully. However, it does not disclose any potential side effects, rate limits, or permissions required. For a read-only tool, this is adequate but not exceptional.

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 well-structured as a Python docstring with clear Args and Returns sections. It is concise yet informative, with no unnecessary words. Every sentence adds value, and the return schema is provided without redundancy.

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 simplicity (3 parameters, 1 required, no nested objects) and the presence of an output schema in the description, the description is fairly complete. It covers inputs, outputs, and behavior. However, it could be improved by mentioning any constraints or edge cases, such as what happens if the parent technique has no subtechniques.

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, so the description must compensate. It does so by explaining each parameter: technique_stix_id as 'STIX UUID of the parent technique', domain as 'ATT&CK domain', and include_description as 'Whether to include subtechnique descriptions'. This adds significant meaning beyond the parameter names.

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 'Get all subtechniques of a parent technique' clearly specifies the action (Get) and the resource (subtechniques of a parent technique). It distinguishes itself from siblings like 'get_all_subtechniques' and 'get_parent_technique_of_subtechnique' by explicitly targeting a parent technique.

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 does not provide any guidance on when to use this tool versus alternatives. It gives no context for when not to use it or which sibling tools to choose instead. The purpose is clear, but usage context is missing.

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