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

With no annotations, the description carries the full burden and does well: it discloses that the call blocks/pends until approval, that the secret is retrievable only once, and that a second poll redacts it. Auth requirements and error/retry behavior are still unstated, keeping it short of a 5.

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?

Three terse sentences, front-loaded with the action and the gating condition, with zero filler. Every clause carries information an agent needs about timing or one-time retrieval.

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?

No output schema exists, so the description should say more about what a successful poll returns and how to interpret the pending/redacted states. It covers the key lifecycle behavior well but leaves return shape and failure handling unspecified.

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 0% and the description says nothing about any parameter. The required poll_token (minLength 8) and the near-duplicate pollToken alias are left entirely unexplained, so the description does not compensate for the coverage gap.

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 (collect/poll) and resource (lf_agent_ key), plus the trigger condition (after the approve link is opened). It doesn't explicitly name the sibling request_agent_key that presumably precedes it, so sibling differentiation is only implied by the approve-link flow.

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?

It gives clear timing guidance: call it once, after the approve link is opened, and it stays pending until then. However, it never names an alternative tool or states what to do instead if the approve step hasn't happened, leaving the surrounding flow to inference.

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