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

Annotations confirm this is a non-read-only, open-world, non-idempotent write. The description adds genuinely useful behavior beyond that: data is sent to a third party (Ruzora), the assessment is free and ~25 minutes, and the candidate must be informed. It stops short of describing permission/auth implications or repeat-call behavior.

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?

Two dense sentences with no filler; the value proposition and prerequisites are front-loaded. It is compact for the amount of information conveyed, though slightly cramped.

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 10-parameter, non-idempotent, open-world tool with no output schema, the description covers purpose, runtime/cost, data recipients, prerequisites, and return values. It is largely adequate, with the main gap being how errors or the buyer_token flow are handled at call time.

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 10 parameters are already documented, including the buyer_token's dependency on confirm_work_email. The description only loosely echoes some inputs ('both names, the email, company and profile links') and adds no syntax or format meaning. Baseline 3 is appropriate.

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: sends Ruzora's coding challenge and technical questions to a candidate, and names what comes back (candidate link + status link). It is clearly distinct from build/design assessment siblings, though it never names an alternative explicitly.

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?

Usage context is implied ('on a candidate the user found') and one prerequisite is stated (the user must confirm the candidate knows). It does not state when not to use this tool, nor does it route to verify_work_email/confirm_work_email for the buyer_token, which only appears in the schema.

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