topics_create_topic

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

Description provides no behavioral information beyond the action. With no annotations, the agent gets no insight into idempotency, error behavior, permissions, or side effects.

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?

Extremely concise at one sentence. It is front-loaded with the essential purpose, but so brief that it borders on under-specification. Still, no wasted words.

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?

Given the tool has 2 parameters, a simple purpose, and an output schema (not shown), the description could be more complete by mentioning uniqueness constraints, required permissions, or default behavior. Currently it is too sparse to fully inform correct use.

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%, so baseline is 3. The description adds no additional meaning to the parameters, which are already well-documented in the schema (e.g., name supports FIFO suffix, region defaults to configured region).

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?

Description 'Create a topic.' clearly states the action and resource. It is specific enough to distinguish from sibling tools like topics_publish or topics_subscribe, but lacks any scope or context (e.g., what kind of topic).

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 any when-to-use or when-not-to-use advice, leaving the agent to infer from the name alone.

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