batch_analyze

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

With no annotations provided, the description carries the behavioral burden. It discloses meaningful behavior: calculations happen in parallel, each keyword receives a full niche score, and results are returned as a sorted comparison table. It does not discuss side effects or data persistence, but this tool is clearly an analytical read operation.

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?

Three short, focused sentences front-load the core purpose and return behavior. Every sentence earns its place, and there is no redundant restating of the schema.

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 one simple parameter, no annotations, and no output schema, so the description must carry the full explanatory load. It does so by covering input limits, processing behavior, and the return format in a complete and usable way.

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 the single 'keywords' parameter is already well documented. The description adds modest context by noting the batch nature and the 10-keyword limit, but it does not materially extend the schema's explanation of the parameter.

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 states a clear verb and resource: batch niche analysis for up to 10 keywords. It also explains what it produces (a full niche score per keyword and a sorted comparison table), making it easy to distinguish from a single-keyword tool like niche_score.

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 phrase 'Useful for comparing multiple keyword candidates at once' provides clear context for when to use the batch tool. It does not explicitly name alternatives like niche_score for single-keyword analysis, but the intended use case is strongly implied.

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