Digital Credentials: Get_credential_allotment

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered structurally. The description adds nothing behavioral beyond that—it does not explain what an 'allotment' represents (a count, a limit, a quota reset cycle) or whether the value is account-wide or per-credential-type.

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?

A single short sentence with the resource front-loaded and no wasted words. It is efficient, though its brevity reflects under-specification rather than disciplined tightening.

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?

There is no output schema and no parameters, so the description must carry the meaning of the returned value—yet it never defines what an 'allotment' is or how it differs from the allegion credential allotment sibling. It is minimally adequate for a zero-arg read call but leaves the key domain concept unexplained.

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?

The tool takes zero parameters, and the schema coverage is 100%, so there is no parameter semantics for the description to compensate for. Baseline 4 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 specific verb (Get) and resource (digital credential allotment) scoped to 'this account', which is clearer than a bare tautology. However, it does not distinguish itself from the sibling 'Get_allegion_credential_allotment', leaving the agent to guess which allotment tool applies.

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?

No when-to-use guidance, no prerequisites, and no mention of the near-identical sibling tool 'Get_allegion_credential_allotment' or when this generic allotment should be preferred over that one. The agent receives no routing information.

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