list_dex_fleet_status_devices

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

With no annotations, the description must disclose behavior, but it only says 'List... by device'. It does not mention pagination, filtering, ordering, whether the response is aggregated per device or raw status entries, or any operational characteristics. The read-only nature is implied by 'List', but key behavioral details are absent.

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, tight sentence with no filler words. It is appropriately front-loaded with the action and resource. It is concise, though slightly vague, and could have included a bit more detail without becoming verbose.

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?

Given no output schema, no annotations, and multiple closely related DEX fleet tools in the sibling list, the description is too thin to fully inform an agent. It doesn't explain what 'by device' means precisely, what the return shape is, or how this differs from live/over-time variants, leaving important selection and invocation context 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?

The schema provides 100% coverage for the single parameter, account_id, with a description ('The account ID'). The tool description adds no extra meaning about how account_id is used or any constraints, so it meets the baseline but does not enrich the parameter semantics.

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 states a clear action ('List') and a resource ('DEX fleet status') with a qualifier ('by device'). This gives a basic understanding of the tool's purpose, but it doesn't explicitly differentiate it from closely related siblings like get_dex_fleet_status_live or get_dex_fleet_status_over_time, leaving some ambiguity about the exact scope.

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 about when to use this tool versus its alternatives. There are several DEX fleet-related siblings in the tool list, and the description offers no conditions, exclusions, or hints on how this tool differs from them, leaving the agent to guess or inspect the schema.

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