gcp_create_service_account

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

Description does not disclose behavioral traits such as what happens if the service account already exists, required permissions, or whether the account is created enabled or disabled. Without annotations, the description carries full burden but is insufficient.

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?

Single sentence is concise and front-loaded. No unnecessary words, but lacks structure like bullet points or bolding. Appropriate for a simple 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?

No output schema provided and no annotations. Description does not explain return values, error cases, or side effects. For a creation tool with 4 parameters, more context is needed for completeness.

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?

Input schema has 100% description coverage, so the description adds no extra meaning. Baseline is 3. The description does not enhance or contradict the schema.

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?

Clearly states 'Create a new service account in a GCP project', specifying the verb and resource. It distinguishes from sibling tools like gcp_delete_service_account and gcp_enable_service_account. However, it does not specify scope or constraints like 'uniqueness' or 'default enabled status'.

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 on when to use this tool versus alternatives. Lacks mention of prerequisites (e.g., IAM permissions) or when not to use it (e.g., if service account already exists). No context for usage conditions.

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