ibmcloud_iam_service_id

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

With no annotations, the description carries full responsibility for disclosing behavior. It only says 'Get service ID details' with no mention of permissions, read-only safety, potential errors, or the structure of the returned details. This is insufficient for a tool that might require authentication or return complex data.

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, focused sentence that directly states the tool's purpose. There is no fluff or redundant information, and it is front-loaded with the action verb 'Get'.

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 tool is simple (one parameter, no output schema), but the description omits any explanation of what 'details' means, what the response looks like, or any error/edge cases. Because there is no output schema, the description should clarify the return value, but it does not.

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 fully describes the single parameter 'name' as 'Service ID name or UUID', so the description adds no extra meaning. Since schema coverage is 100%, the baseline of 3 applies; the description does not need to compensate.

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 'Get service ID details' clearly states a specific verb ('Get') and resource ('service ID details'). It is obviously distinct from the sibling list tool 'ibmcloud_iam_service_ids' and create/delete tools, though it doesn't explicitly differentiate itself beyond the implied singular/plural contrast.

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?

There is no guidance on when to use this tool versus alternatives like `ibmcloud_iam_service_ids` for listing or `ibmcloud_iam_service_id_create` for creation. The description provides no context about typical use cases or prerequisites (e.g., requires an available service ID name/UUID).

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