A3.8/5.0

Behavior4/5

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

Annotations only declare readOnlyHint=false, destructiveHint=false, openWorldHint=false; the description adds real behavioral context beyond that: a cost of $0.05 and an API-key requirement, plus a scope limitation on what normalization will not touch. It does not say whether a preview artifact is persisted or how long it lasts, but 'preview' here describes the scope of changes shown, not a read-only claim, so it does not conflict with readOnlyHint=false.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One front-loaded sentence plus a compact parenthetical carrying the scope caveat, cost, and auth requirement. Every clause earns its place with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need no explanation, and the description covers purpose, scope, cost, and auth. The remaining gaps are the undocumented 'rules' parameter and the lack of routing to the apply sibling, both minor for a zero-required-parameter preview tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 67%: request_id and idempotency_key are documented in the schema, while the 'rules' array is not described there. The description's 'whitespace/phone/handle' hints at the kinds of rules the parameter accepts, adding marginal value, but it does not explain the rules parameter's format or accepted values.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: previewing normalization (whitespace/phone/handle) changes to people records, plus a scope caveat ('no title-case of stylized names'). It is clearly distinguishable in intent from the apply counterpart, but it never names that sibling (normalize_people_apply), so differentiation is left implicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The word 'Preview' implies this should be run before applying normalization, but the description gives no explicit when-to-use, no prerequisites, and no pointer to normalize_people_apply as the follow-up. Usage is inferable rather than stated.

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