Annotations declare readOnlyHint=true and destructiveHint=false, indicating a safe read operation. The description adds the terms 'deterministic' and mentions both rules and folders as outputs, but does not disclose other behaviors like error handling, rate limits, or required permissions. With annotations covering the safety profile, the description adds moderate value.
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 a single, front-loaded sentence that communicates the tool's purpose without any superfluous words. Every part earns its place.
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 tool has one required parameter, a full output schema (not shown but mentioned), and the description succinctly covers the core functionality. It does not mention pagination or limits, but for a simple list operation with an output schema, the description is adequately 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?
Schema coverage is 100%, so the baseline is 3. The description does not provide any additional meaning beyond the schema's property definitions for the 'id' parameter.
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 verb 'List' and specific resources: 'deterministic server-side inbox rules' and 'available destination folders'. It differentiates from sibling tools like 'shipmail_set_mailbox_rules' and 'shipmail_list_mailbox_folders' by combining both outputs in one operation.
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 implicitly suggests using this tool before setting rules via 'shipmail_set_mailbox_rules', but it lacks explicit guidance on when to use this tool versus alternatives. No when-not-to-use or alternative references are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
