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

No annotations are provided, so the description must fully disclose behavior. It only says 'save optional company information,' which indicates a write operation but lacks details on side effects, idempotency, error handling, or what happens if the signup is not pending. For a tool with 10 parameters and a potentially critical step, more transparency is needed.

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 a single sentence, front-loading the purpose ('Run normal Sulvo signup step 3'). It is concise with no wasted words. However, given the 10 parameters, a slightly longer description could improve clarity without losing conciseness.

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?

With 10 parameters, no annotations, and no output schema, the description is insufficient for an agent to fully understand tool behavior. It does not mention response format, error conditions, required prerequisites (e.g., pending signup), or how this step interacts with other signup stages. The description covers only the basic purpose.

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 input schema has 0% description coverage, meaning the description must compensate. The description adds only the vague grouping 'company information' without explaining individual parameters like outputFormat, employeeCount, or monthlyAdRevenue. It does not clarify that outputFormat controls response format, or that employeeCount and monthlyAdRevenue have constraints (exclusiveMinimum>0).

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 identifies the tool as 'Run normal Sulvo signup step 3: save optional company information for a pending Sulvo signup.' The verb 'save' and specific resource 'company information for a pending Sulvo signup' make the purpose unambiguous. It distinguishes itself from sibling tools by referencing signup step 3, which is unique among the listed siblings.

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 by stating it is 'step 3' of the signup process, suggesting a sequence. However, it does not explicitly state when to use or avoid this tool, nor does it mention alternatives among siblings. An agent would benefit from knowing prerequisites (e.g., an existing pending signup) or that this step is optional.

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