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

No annotations are provided, so the description carries the full behavioral burden. 'List' implies a read-only operation, but the description does not explain output shape, pagination behavior, whether results are filtered by authorization, or what a 'checkpoint' contains. The identity/authorization sentence adds minor context but not enough for an agent to predict 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?

The description is short and front-loads the core action. The second sentence is somewhat vague and reads like a policy note rather than actionable tool information, but overall the text is efficient.

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 no annotations, no output schema, and completely undocumented parameters, the description does not provide enough detail for confident invocation. It omits what a checkpoint is, how results are returned, how limit/state affect results, and what authorization constraints actually mean in practice.

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?

There are two parameters (limit, state) with 0% schema description coverage and no enums. The description does not mention either parameter or clarify what 'state' means (geographic state, checkpoint state, approval state), so an agent gains essentially no parameter-level meaning from the 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 states a clear verb ('List') and resource ('human KYC checkpoints'), making the core operation understandable. It implicitly distinguishes itself from sibling mutation tools like human_kyc_claim, human_kyc_complete, and human_kyc_reconcile, though it never names them 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?

There is no guidance on when to call this versus the sibling human_kyc_* tools, no prerequisites, and no exclusions. The second sentence discusses contributor identity authorization, which is context rather than usage selection guidance.

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