Messaging_createDigitalAccessKey

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

The description discloses that this is a 'catalog entry' that 'runs in your Kuudo deployment, not here,' which is meaningful behavioral context beyond the absent annotations. However, it does not discuss permissions, side effects beyond the message send, or failure behavior.

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 definition is compact: two sentences that front-load the purpose and then add essential runtime context. Every clause earns its place without filler or repetition.

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 core action and the notable runtime characteristic are covered, making the tool minimally usable. Still, without annotations or an output schema, the description leaves unclear what inputs are required and what a successful invocation returns.

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 schema defines zero parameters, so the baseline is 4. The description does not elaborate on how the buyer, order, or digital access key are identified, but with no schema-declared parameters this is not a significant deduction.

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: sends a buyer a message to share a digital access key for digital content in their order. The verb 'sends' and the specific resource 'digital access key' set it apart from generic Messaging_* siblings, though it does not explicitly name an alternative.

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 guidance is given about when to use this tool versus other Messaging_* options. The use case is implied by 'Sends a buyer a message...', but there are no conditions, exclusions, or alternative tool references.

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