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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the record's field composition (consent type, relation type, date, expiration, proof) and the underlying endpoint, but says nothing about what happens when a member has no consent record or whether any authorization scope is required.

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?

Two tight fragments totalling one line, with the substantive field list front-loaded. It is efficient, though the absence of a verb makes it read more like a field dump than a sentence.

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 single-parameter read with no output schema, listing the returned fields is exactly the right compensation. The only meaningful gap is error/empty-state behavior when no consent record exists.

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 coverage is 100% and the single 'key' parameter is fully documented in the schema as an email address or numeric id. The description only repeats the path placeholder {key} and adds no format, encoding, or lookup-fallback guidance beyond what the schema already states.

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?

Names a specific resource (a member's consent record) and enumerates the fields it carries, which distinguishes it from the sibling cyberimpact_get_member profile lookup. It omits an explicit verb but the title and name supply 'get', so the intent is unambiguous.

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 parenthetical 'for CASL compliance checks' gives an implied usage context, but there is no explicit statement of when to call this versus cyberimpact_get_member or the list/unsubscribed tools, and no prerequisites or exclusions.

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