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

With no annotations provided, the description carries the full burden of disclosing behavior. It adds valuable context such as global coverage and per-endpoint pricing, but it omits important behavioral traits like authentication requirements, rate limits, response format, error handling, or any side effects. This is a partial disclosure at best.

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 well-structured: a one-line summary, coverage note, and a clearly bulleted list of endpoints with prices and short explanations. It is somewhat long due to the number of endpoints but stays organized and front-loaded. A minor truncation ('skills gap analys') keeps it from a 5.

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 complex tool with 18 parameters and 10 actions, the description gives enough context to understand each endpoint's purpose and general scope, but it lacks an output schema and does not explain response formats, parameter requirements per endpoint, or how to combine parameters. This is moderately complete but leaves notable gaps.

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 the baseline is 3. The description adds endpoint-level purpose (e.g., 'visa' explains it covers nationality/destination pairs), which helps map some parameters to endpoints, but it does not provide parameter-specific details beyond what the schema already contains.

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 TalentPulse as a global workforce intelligence API and enumerates ten specific endpoints (salary, remote-compliance, employer-of-record, etc.), each with a concise purpose. This strongly differentiates it from the many sibling *pulse tools by focusing on talent/workforce data.

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?

Each endpoint is listed with a distinct purpose (e.g., 'Salary benchmarking — any role, any location globally'), giving the agent clear context on which action to choose for a given task. However, there is no explicit 'when not to use' guidance or comparison to alternative sibling tools, which would push this to a 5.

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