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

The annotations already declare a non-read-only, idempotent, non-destructive mutation. The description adds useful behavioral context beyond annotations: an agent credential is required, idempotency_key is required, public knowledge remains open, and the operation does not change specialist titles or execution permissions.

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-loaded with the core action. Most sentences earn their place by clarifying scope, credentials, and permission effects, though the final sentence about outcome credit is somewhat opaque.

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 mutation tool with a required nested object, a 20-value category enum, and no output schema, the description covers credentials and permission effects but leaves the category semantics and the effect of enabling or disabling unexplained. It is adequate but has clear gaps for correct invocation.

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%, so the description must compensate for undocumented parameters. It mentions the required idempotency_key and an agent credential, but it does not explain the nested input.category enum values T01-T20 or the meaning of input.enabled.

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 action and resource: enabling or disabling public domain matching. It clarifies that membership does not confer a specialist title or execution permission, but it does not explicitly distinguish itself from sibling tools such as match_specialists.

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 implies that the tool toggles domain matching, but it gives no explicit guidance on when to use it versus alternatives or when not to use it. No sibling tool is named, and no exclusion criteria are provided.

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