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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description usefully adds the authentication requirement (organization API key), but says nothing about result size, pagination, or what the inventory contains.

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 short sentences, front-loaded with the resource and scope, and the auth prerequisite is compact. No filler, though nothing beyond the bare minimum is offered.

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 read-only inventory tool with no output schema, the description does not describe what the inventory returns (systems, algorithms, quantum-vulnerability status) or whether results are paginated. Adequate given annotations cover safety, but incomplete for a tool whose output shape is undefined.

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 optional parameter is already documented as 'One system; omit for all'. The description adds no syntax or scoping detail beyond that, so the schema does the heavy lifting and baseline 3 applies.

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?

States a clear verb+resource: retrieving the current cryptographic inventory of the organization's systems. It does not distinguish itself from adjacent siblings such as gov_pqc_classify, gov_pqc_plan, or gov_pqc_export, which an agent must infer from the names alone.

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 gives a precondition (organization API key required) but no explicit when-to-use or when-not-to-use guidance relative to gov_pqc_classify, gov_pqc_plan, or gov_pqc_export. Usage is only implied by the tool name and scope.

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