sap_sns_get_domain_pda

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

No annotations are provided, so the description must disclose behavior. It only says 'Derive', implying a read-only computation, but does not mention any side effects, required permissions, or the nature of the output. The tool likely returns a PDA without mutation, but this is not explicitly stated.

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 concise (one sentence) and front-loaded with the key purpose. It could be slightly expanded without losing conciseness, but as-is it is efficient.

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 simple tool with one parameter and no output schema, the description provides a minimal but adequate overview. However, it lacks explanation of what a PDA is or what the return value looks like, which could be helpful for an AI agent.

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 input schema has 100% coverage with a clear description for the only parameter 'domain'. The description adds no further meaning beyond the schema, but this is acceptable as baseline given full schema coverage.

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 ('Derive') and the resource ('SNS domain PDA') with a specific scope ('.sol domain'). It distinguishes itself from sibling sap_sns_* tools by focusing on deriving the PDA, but does not explicitly contrast with similar tools like sap_sns_get_domain_records.

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 provided on when to use this tool vs. alternatives, such as when a PDA is needed before other SNS operations. There are no prerequisites or contextual hints.

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