create_topic_with_schema

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

With no annotations provided, the description carries full burden but only states it 'Creates' without disclosing behavioral traits like permissions needed, whether it's idempotent, error handling, or rate limits. It mentions a return but doesn't describe what 'Creation result' entails beyond the output schema.

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 appropriately sized with a clear summary sentence followed by structured Args and Returns sections. Every sentence adds value, though the parameter explanations could be more front-loaded in the summary for better initial clarity.

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?

For a 9-parameter creation tool with no annotations, the description covers parameters well but lacks behavioral context. The presence of an output schema reduces the need to explain returns, but more guidance on usage and error cases would improve completeness given the tool's complexity.

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 description coverage is 0%, but the description compensates by listing all 9 parameters with brief explanations, including defaults for partitions and replication, and clarifying when key_schema is required. It adds meaningful context beyond the bare schema, though some details like configs structure remain vague.

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 'Creates' and the resource 'new Kafka topic', specifying it includes 'optional format and schema configuration'. It distinguishes from sibling 'create_topic' by explicitly mentioning schema capabilities, making the purpose specific and differentiated.

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 implies usage for creating topics with schema configuration, but doesn't explicitly state when to use this vs. the simpler 'create_topic' sibling tool. It mentions optional parameters but lacks clear guidance on alternatives or exclusions.

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