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

With only generic annotations available, the description adds valuable behavioral guardrails: the submission must be bound to the prior challenge_id/email, and code guessing or looping is disallowed. This is especially important because the annotations already mark the operation as non-read-only and non-idempotent. The description does not disclose error/retry behavior, but it provides the most critical behavioral constraints.

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 dense sentence that front-loads the purpose and then lists the two most important constraints. Every clause earns its place, and there is no filler or repetition of obvious information.

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 verification-completion tool with no output schema, the description plus parameter schema covers the essential calling contract: required fields, the source of challenge_id, and the prohibition on guessing codes. The main gap is the lack of response/error semantics, but the invocation guidance is otherwise sufficient.

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 tool description adds cross-parameter semantics beyond the schema: email must be the same email used before, challenge_id must be the exact value returned by the prior tool, and code must be the real user-provided value. This is operationally important and not fully inferable from individual schema fields. The unmentioned product and account_id parameters are already reasonably documented by the enum, default value, and account_id description.

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 opens with 'Complete LinkedIn company-member verification', which names a specific verb and resource. The title explicitly says 'Submit company member OTP', and the workflow relationship to linkedin_verify_company_member_email is clear, so the agent can distinguish this tool from its sibling without deeper inspection.

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 makes the precondition and sequence explicit: reuse the same email and exact challenge_id from linkedin_verify_company_member_email. It also gives a clear anti-pattern: never invent or loop over codes. It does not explicitly state when not to use this tool versus an alternative, but the two-step workflow dependency is strong enough to guide correct use.

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