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

With no annotations, the description carries the full burden for behavioral disclosure. It only states that it returns a list and gives parameter sources; it does not mention side effects, authentication requirements, pagination, or any operation-specific behaviors. The '@return: a json object' is minimal and already covered by the output schema.

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 first sentence is duplicated verbatim ('Returns a list of devices registered to receive push messages on this wallet' appears twice), which is redundant and wastes space. The rest is a standard parameter block. This lacks the conciseness expected of a well-crafted description.

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?

The description covers the basic purpose and parameters, and an output schema exists, so return types are not a gap. However, it lacks usage guidance, alternative references, and any caveats (e.g., whether the list is complete or requires specific permissions). For a simple list operation, this is adequate but not comprehensive.

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 input schema has 0% description coverage, so the @param descriptions add value by explaining the provenance of each parameter (e.g., token provided by /access/login). However, the explanations are thin (e.g., wallet_fk is not actually defined, just its source), so it does not fully compensate for the missing schema descriptions.

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 clearly states the verb 'Returns' and the resource 'list of devices registered to receive push messages on this wallet', making the tool's purpose obvious. It does not explicitly distinguish from sibling tools like netfluid__push_message_send, but the read-versus-send distinction is implicit.

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 provides clear context (when you need to see push message devices for a wallet) but gives no explicit guidance on when to choose this tool over alternatives, nor does it mention exclusions or prerequisites beyond the parameter provenance.

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