Create Gtag Config

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

Annotations are absent, so the description carries the full burden of disclosing behavior. 'Create' implies a write operation, but the description does not state permissions needed, whether the operation is additive and non-destructive, or any side effects. For a mutation tool with no annotation coverage, this is a meaningful gap.

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 front-loaded sentence with no wasted words. It states the action and target immediately and does not repeat schema details.

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?

The schema fully documents inputs, an output schema is present, and the purpose is clear, so the call can probably be constructed. However, without annotations and with no usage or behavioral context, the description is only minimally complete for a write operation. The agent has to assume standard create semantics.

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 input schema already provides 100% coverage for all four parameters, including a descriptive gtag_config example. The description itself adds no parameter-level meaning, but under the baseline for high schema coverage this is acceptable.

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'), a specific resource ('Google tag configuration'), and a scope ('in a workspace'), so an agent can tell it apart from update/delete/get variants. It is not explicitly contrasted with sibling create_tag, but the resource type is distinct enough. It could earn a 5 by explicitly saying it creates a GtagConfig entity as opposed to a tag.

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 when-to-use, prerequisites, or alternatives are mentioned. The description simply states what it does, leaving the agent to infer that it is appropriate whenever a new Google tag configuration is needed in a workspace. There is no guidance about when to use create_tag instead.

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