List Domain Pointers

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

The annotations already establish a safe, idempotent read. The description adds the pointer categories and per-entry contents, but gives no further operational context such as empty-result or pagination behavior; the return summary is also less essential because an output schema exists.

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?

Two short sentences front-load the operation and scope, then succinctly explain the alias/redirect model. There is no filler or unnecessary repetition of the safety annotations.

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 list operation with one fully documented required parameter, read-only annotations, and an output schema, this supplies the invocation-critical resource scope and result concepts. Additional operational details would be optional rather than necessary for correct selection and invocation.

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%, and the domain parameter already includes an example and syntax constraints. The description clarifies that this is the domain whose pointers are listed, but adds no parameter format or validation detail beyond the schema, so the baseline applies.

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 gives a specific verb and resource: listing domain pointers attached to one domain, with pointers defined as aliases and redirects. That scope and the type/target distinction separate it from list_domains, get_domain, and the create/delete pointer tools.

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?

It provides clear selection context: use it to inspect the aliases and redirects attached to a particular domain. It does not explicitly route agents to list_domains or get_domain for other needs, which keeps it from a 5.

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