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

Annotations already establish that this is a safe, read-only, idempotent, non-destructive, closed-world calculation. The description adds the key behavioral idea that results depend on a per-field conversion recovery rate, but does not describe output form, limits, or other traits beyond the 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 first sentence front-loads the core purpose and is efficient. The second sentence is a promotional external link that is not strictly needed for tool invocation, keeping it from being maximally concise.

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 six-parameter calculator with full schema coverage and clear annotations, the description states what the tool returns: extra leads and pipeline value. It does not explain output format or units, but no output schema exists and the return concept is inferable.

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 100%, so all six parameters are already documented in the input schema. The description mentions trimming form fields and recovery per field, which aligns with the schema, but adds no syntax, units, or parameter-level detail beyond what the schema provides.

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?

States a specific verb and resource: estimate extra leads and pipeline value unlocked by trimming form fields. It is clear enough for an agent to know the calculation, but it does not explicitly differentiate itself from similar friction or conversion calculators in the sibling list.

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?

Provides no when-to-use guidance, prerequisites, or alternatives. The implied context is form-field optimization, but there is no explicit routing to or away from related tools such as friction_point_identifier or mobile_checkout_friction_tester.

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