insurance_reserving__ibnr

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

No annotations are provided and the description gives no information about side effects, required permissions, rate limits, or whether the tool is read-only or destructive. The behavioral profile is completely opaque.

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?

While the description is extremely short, this is under-specification rather than conciseness. No sentences earn their place; the single phrase adds negligible information. A 1–2 word label is not an adequate description.

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 that the tool likely performs a complex IBNR calculation with two required array inputs and no output schema, the description is radically incomplete. It fails to explain the calculation method, input order, output format, or how it integrates with other reserving tools.

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 has 0% description coverage for parameters. The arrays 'ultimates' and 'paid_to_date' are undocumented. The description adds no meaning—does not explain what data they expect, their shape, or units. Without compensation, the agent cannot prepare correct inputs.

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 is merely '[insurance-reserving] ibnr', which is a tautology of the tool name and acronym suffix. It does not state what the tool does (e.g., calculate, estimate) nor identify the specific resource (e.g., IBNR reserve). A user would have to guess its purpose.

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?

There are no guidelines on when to use this tool versus sibling tools like insurance_reserving__development_factors or insurance_reserving__project_ultimates. The description offers zero context for appropriate invocation.

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