create_account

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 the action (create) but does not disclose any side effects, auth requirements, or constraints beyond the implicit existence of the group. This is a minimal level of disclosure for a mutation tool.

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, concise sentence that efficiently conveys the core purpose. It is front-loaded with the primary action and avoids filler, though it could have included slightly more contextual detail without becoming verbose.

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 creation tool with two parameters, the description provides the essential purpose. The presence of an output schema reduces the need to explain return values, but the description lacks usage guidance and behavioral context, leaving it at a minimally sufficient level for a tool of this simplicity.

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, and the tool description adds no parameter-specific meaning. While the param names (name, account_group_id) are somewhat self-explanatory, the description does not clarify formats, uniqueness, or any other nuances, so it fails to compensate for the low schema coverage.

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 resource ('account'), clearly indicating the operation. It also specifies the context ('in an existing account group'), which distinguishes it from any hypothetical group-creation tool and from the sibling read tools.

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 phrase 'in an existing account group' implicitly tells the agent that the account group must already exist, implying a prerequisite. However, it does not explicitly state when to use this tool over alternatives or provide exclusions, limiting guidance to an implied usage context.

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