Create Temporary Access Pass

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

The description discloses several important behavioral traits beyond annotations: multi-use by default, regeneration until alphanumeric, lifetime limited by tenant policy, and return of the passcode for out-of-band delivery. These details are valuable and not presented in the annotations.

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 three sentences, front-loaded with purpose, followed by behavioral details and return value. Every sentence adds meaningful information without unnecessary fluff.

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?

The description covers essential context for a creation tool: purpose, key behaviors, return value, and a security caveat. It lacks explicit error conditions or prerequisites like admin role, but given the absence of an output schema and the richness of the description, it is fairly complete.

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 description adds meaning to several parameters: 'multi-use by default' relates to isUsableOnce, 'regenerated until alphanumeric' relates to requireAlphanumeric, and 'lifetimeInMinutes bounded by policy' adds context. However, it does not explain maxAttempts, startDateTime, or user. With zero schema description coverage, this is partial compensation.

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 clearly states the action ('Create'), the resource ('Temporary Access Pass'), and the specific use case ('passwordless first sign-in / MFA setup'). It also differentiates from related tools like delete_temporary_access_pass by emphasizing creation and default multi-use behavior.

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 provides clear context for when to use the tool: during initial sign-in or MFA setup. It does not explicitly mention alternatives or exclusions, but the scenario is specific enough to imply appropriate usage. The security note to deliver the passcode out-of-band adds additional usage context.

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