create_sc_service_user

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

No annotations are provided, so the description must fully disclose behavior. It only states the creation action and the mutual exclusivity constraint, but lacks information on permissions, side effects, error conditions, or the return value (though output schema exists). This is insufficient for safe invocation.

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?

Two sentences, front-loaded with the purpose, and a clear constraint. No redundant or unnecessary information. Very efficient.

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 description does not explain prerequisites (e.g., repository must exist), the purpose of the service user, or the format of the credential parameters. Although an output schema exists, the description lacks context for complete understanding.

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%, but the description adds critical semantic nuance: the mutual exclusivity of 'aws_secrets_manager' and 'azure_key_vault' parameters, which is not enforced by the schema. This adds value beyond the schema descriptions.

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 verb 'create' and the resource 'service user for a repository', distinguishing it from sibling tools like 'delete_sc_service_user' or 'create_sc_repo_user'. The additional constraint about providing exactly one credential type adds specificity.

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 explicitly says 'Provide exactly one of aws_secrets_manager or azure_key_vault', which is a crucial usage constraint. However, it does not compare to alternatives like 'create_sc_repo_user' or explain when a service user is appropriate.

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