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

With no annotations provided, the description carries the full burden for behavioral disclosure. It only says 'List marketplace services' without detailing any behavior such as output format, pagination, authentication requirements, or the effect of the optional 'service' parameter (which is only in the schema). This is insufficient for a tool with no annotation safety hints.

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 fully earns its place and is as concise as possible for a tool of this simplicity.

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 has low complexity but the description is extremely terse. Given that there is no output schema and no annotations, the description should provide more context about what the tool returns or when it is appropriate to use, especially to avoid confusion with sibling tools like cf_services or catalog tools. The current description is insufficient for an agent to fully understand the tool's role.

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 covers the only parameter 'service' with a clear description ('Show plans for a specific service'), giving 100% coverage. Since the schema already explains the parameter, the description does not need to add much, and the baseline of 3 is appropriate.

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 action ('List') and resource ('marketplace services'), making the primary purpose unambiguous. However, it does not distinguish this tool from the similar sibling tools like ibmcloud_cf_services or ibmcloud_catalog_search, so it misses the chance to differentiate itself.

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 is provided on when to use this tool versus alternatives. The description does not mention any context, prerequisites, or conditions that would help an agent decide between this and the many related listing tools.

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