create_group_child

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 states 'create' (mutation) but does not disclose required permissions, side effects (e.g., whether it affects existing groups), error conditions, or if group_data must follow a specific schema. The description is too brief to be 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 sentence of 7 words, which is concise but lacks structure. It front-loads the core action but omits important details. While not verbose, it sacrifices completeness for brevity.

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 has 3 required parameters including a nested object, no output schema, and no annotations, the description is insufficient. It does not explain the hierarchical context, required format of group_data, or any constraints. A mutation tool like this needs more context to be used correctly.

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% (all parameters described in the schema). The description adds no additional meaning beyond the schema field descriptions. It does not clarify that 'group_id' is the parent's ID or provide details about 'group_data' structure. Baseline is 3 due to high coverage, and no extra value is added.

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 it creates a child group under a parent group, using the verb 'create' and specifying the resource relationship. It distinguishes from 'create_group' which creates a top-level group. However, it could be more explicit that 'group_id' refers to the parent group.

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?

No guidance is provided on when to use this tool versus alternatives like 'create_group' or 'add_default_group'. There is no mention of prerequisites (e.g., parent group must exist) or that this is for hierarchical group structures. With many sibling tools, this is a significant gap.

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