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

With no annotations, the description carries the full behavioral burden. It discloses only that identity-document content is not stored in AgentLot, but it does not state auth requirements, mutation side effects, idempotency behavior, error conditions, or how task/payout state changes.

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 front-loaded sentence with no filler, so it is concise. Its brevity is efficient, though it does not compensate for the missing operational detail required by a five-parameter, unannotated tool.

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?

The tool has no annotations, no output schema, five parameters at 0% schema description coverage, and a nested evidence object. The description supplies only a high-level purpose and one privacy constraint, leaving critical invocation, parameter, return, and side-effect information 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 explains none of the five parameters. In particular, task_id, contributor_id, kyc_completed, evidence, and payout_account_confirmed are undocumented, and the nested evidence object is not defined or constrained.

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 specific verb and resource: 'Record completion of authorized provider KYC.' It also adds a privacy scope constraint, but it does not explicitly distinguish this tool from sibling KYC tools such as human_kyc_claim, human_kyc_reconcile, or human_kyc_market.

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 is implied: this records completion after an authorized provider KYC process. However, the description gives no explicit when-to-use conditions, prerequisites, exclusions, or routing guidance relative to the sibling KYC and payout tools.

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