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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds that the call returns qualitative detail — how each provider executes and how it holds funds — plus that entries carry ids, which is useful since there is no output schema. It doesn't say whether the list is exhaustive/static or ordered, a minor gap.

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 sentences, front-loaded with the core action and followed by the actionable next step. The parenthetical provider list is somewhat long but earns its place by concretizing scope for the agent.

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?

With no parameters and no output schema, the description does the necessary work of characterizing what comes back (providers, execution, custody, ids) and how to use it. Only the shape/ordering of the response is left implicit.

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 baseline is 4. The mention of 'ids' refers to returned fields rather than inputs and does not mislead, since the schema shows an empty object.

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?

States a specific verb (List) and resource (cross-chain protocols TorrentSwap routes through), enumerates concrete examples, and says what each entry conveys (execution method, fund custody). An agent can immediately distinguish this from get_quote, list_assets, or get_swap_status.

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?

Explicitly ties the output to a sibling: 'Use the ids to filter get_quote,' which tells the agent this is the discovery step before quoting. No explicit when-not or exclusion guidance, but the usage context is clear.

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