rm_create_assignment_subtask

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

Annotations already indicate this is not read-only and not destructive, and the description simply restates the creation action without adding behavioral context such as permissions, validation, idempotency, or effects on parent records. It does not contradict the annotations, but it also adds little beyond them.

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 sentence with no filler, front-loading the action and resource. It is appropriately concise for a straightforward create tool.

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 create operation with an output schema and annotations, the description is close to adequate. However, the total absence of parameter semantics and usage guidance leaves some gaps for an agent trying to invoke it correctly, especially around what its parameters require.

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%, and the tool description does not explain what project_id, assignment_id, description, or completed mean or how they relate. The phrase 'under a project assignment' hints at the parent relationship but is not enough to compensate for missing parameter documentation.

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 ('Create') and a specific resource ('subtask under a project assignment'), which clearly distinguishes it from the sibling tools like rm_create_assignment or rm_list_assignment_subtasks. It is clear and unambiguous, though it does not explicitly name alternatives.

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 explicit guidance on when to use this tool versus rm_create_assignment or the subtask list/delete siblings. No prerequisites, exclusions, or alternative routing are mentioned; the description only implies its purpose.

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