can_create_child

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description adds limited extra value. It implies a non-mutating check but doesn't explicitly state that no creation occurs or disclose any side effects. The example adds contextual insight but not additional behavioral details beyond what annotations provide.

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 concise, front-loading the purpose, and includes a helpful example. It is not verbose, but the example could be more explicit about parameter usage. Overall, it is efficient and well-structured.

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 low schema coverage and missing parameter details, the description is incomplete for correct invocation. It does not specify valid values for parent_target_type and child_target_type, nor does it define how to obtain parent_target_id. While an output schema exists, the input semantics are not fully covered, leaving an agent to guess or explore.

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 explains workspace_id via a pointer to list_workspaces() but does not clarify parent_target_type, child_target_type, or parent_target_id beyond the example. The example gives a concrete case but leaves allowed values and formats ambiguous, especially without enums.

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 purpose: checking if the current user can create a child resource inside a parent. It uses a specific verb ('check') and resource (permission for child creation), and the example ('Channel' inside 'HubProfile') makes it concrete and distinct from sibling permission tools like can_read or can_edit.

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 implies usage by stating it checks create-child permission, and the example clarifies the scenario. However, it does not explicitly name alternatives or conditions for when not to use it, though the sibling set includes other permission checks that are clearly different. It provides context but no explicit exclusion guidance.

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