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

No annotations exist, so the description carries the full burden. It implies a read ('registry') and discloses that address is null for native assets, but says nothing about scope (all chains? all listed assets?), ordering, pagination, or whether delisted assets are included — material for a tool used to validate counterparty assets.

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?

A single compact sentence with zero filler, and the key concept ('Tradeable asset registry') is front-loaded. It is arguably over-trimmed into a fragment, leaving no room for the usage or scope context noted above.

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?

Because no output schema exists, the description's field list does useful work explaining the return records, which is the main thing an agent needs. However, for a listing tool it omits scope and ordering, so it is adequate rather than 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?

The tool takes zero parameters, so there is nothing to disambiguate and the baseline of 4 applies. The description's field enumeration describe return shape rather than inputs, which belongs to the transparency dimension instead.

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 identifies the resource concretely as a 'Tradeable asset registry' and enumerates the record fields, so an agent understands it retrieves the list of tradeable assets. It lacks an explicit verb ('list/return all'), but the noun phrase plus the tool name makes the intent unambiguous and clearly distinct from the RFQ/swap siblings.

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?

There is no statement of when to call this tool, no prerequisites, and no reference to alternatives. With zero parameters there is little to misuse, but an agent gets no signal about whether to call it before quote_rfq or request_listing, which is exactly where this registry would matter.

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