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

The description adds behavioral context beyond the readOnlyHint and openWorldHint annotations by stating 'Returns normalized real research records; never mock data.' This tells the agent the output type and that data is live, not simulated. It does not contradict annotations.

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 entire description is one sentence, front-loaded with the purpose verb 'Search', and every clause adds value—'live', 'through OpenAlex', and 'never mock data' are all meaningful. There is no redundant or generic filler.

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 is brief but covers the core behavior, data source, and return type. With no output schema, 'normalized real research records' is slightly vague about fields or pagination, but for a two-parameter read-only search tool with clear annotations, this is largely sufficient.

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%, so the description must compensate. It implies that 'query' is the search term for scholarly works but says nothing about the optional 'limit' parameter. The schema's own type and bounds (integer 1-25) carry that meaning, so the description adds only marginal value for query and none for limit.

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 opens with a specific verb and resource: 'Search live scholarly works through OpenAlex.' This clearly distinguishes the tool from its siblings (kata_apply_command, kata_execute_program, etc.), none of which perform scholarly search.

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 gives clear context for when the tool is appropriate: searching live scholarly works via OpenAlex. It doesn't explicitly state when not to use it or name alternatives, but the sibling set has no overlapping search tools, so the use case is unambiguous enough.

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