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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful tenant-scoping and explains the domain concept of a dynamic endpoint, but it does not discuss pagination, filtering behavior, or any other operational traits beyond that.

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 two concise sentences with no filler. It front-loads the primary purpose before adding the domain definition.

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 tool with rich annotations, a fully described input schema, and an output schema, the description is largely complete. The main gap is the lack of explicit routing guidance against sibling list/get operations, but nothing required to invoke the tool correctly is missing.

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 description coverage is 100%, so page_size, page_token, and slug_prefix are already documented in the input schema. The description adds no parameter-specific meaning or formatting guidance, so the baseline of 3 is appropriate.

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 uses a specific verb and resource ('List the dynamic endpoints') and scopes it to the authenticated tenant. It also defines what a dynamic endpoint is, making the resource understandable. It does not explicitly distinguish this from nearby siblings such as get_dynamic_endpoint or list_dynamic_endpoint_runs.

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 implies enumeration through the verb 'List,' but gives no explicit guidance on when to use this versus get_dynamic_endpoint, preview_dynamic_endpoint, or list_dynamic_endpoint_runs. There are no stated exclusions, prerequisites, or alternative-selection rules.

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