Create Postgres export

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

Annotations already indicate non-readOnly, non-destructive, non-idempotent. The description adds that it calls a POST endpoint, confirming a write operation. However, it does not disclose other important traits like whether the operation is synchronous or async, potential side effects, or prerequisites. No contradiction with 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 exceptionally concise: two sentences plus a documentation link. Every sentence adds value, and the action is front-loaded. No redundancy.

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?

Despite low complexity (1 param, no output schema), the description is incomplete. It does not explain what the export creation returns (e.g., an export object or async task), whether it's synchronous, or any preconditions like permissions. With no output schema, these details are essential.

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 has one required parameter (postgresId) with 0% description coverage. The description only mentions 'by ID' without detailing what the ID represents or its format. This is minimal value beyond the schema's type definition.

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 an export), the target resource (Postgres instance by ID), and references the API endpoint. It distinguishes from siblings like render_create_postgres (create a new DB) and render_list_postgres_export (list exports).

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 does not explicitly state when to use this tool versus alternatives. It implies usage for creating exports but lacks guidance on when not to use or when to prefer tools like render_list_postgres_export to check existing exports.

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