sync_cloud_printers

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

With no annotations, the description carries the burden and does add useful behavioral details: it connects via cloud MQTT, works remotely, and depends on a prior login. However, it does not disclose potential side effects of 'sync' (e.g., whether it can alter or remove printer bindings) or what happens on repeated calls, leaving some ambiguity for a state-changing setup tool.

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 terse sentences front-load the action and scope, then add the remote behavior, and end with the prerequisite. Every sentence contributes necessary information with no filler or repetition of the tool name.

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 no-parameter tool with no output schema, the description covers what it does, where it operates, and what must happen first, which is nearly all an agent needs to invoke it correctly. It is only slightly incomplete in not describing what the sync result looks like or whether the connection persists, but this is minor given the tool's simplicity.

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?

There are zero parameters and the schema properties object is empty, so there is nothing to document; the baseline for no-parameter tools is 4. The only requirement mentioned, 'npm run login', is a precondition rather than a parameter and is appropriately stated in the description.

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 specific verbs ('Discover', 'connect') and identifies the exact resource: printers bound to the Bambu cloud account. It also distinguishes itself from LAN/local operations by explicitly saying it works remotely over the cloud MQTT broker, which separates it from sibling tools like add_printer/list_printers that don't have this cloud-connection behavior.

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?

It gives clear context: this is for cloud-bound printers and for remote use off the LAN, plus an explicit prerequisite ('Requires npm run login first'). It does not name alternative tools or state a hard 'when not to use', but the scope and precondition are unambiguous enough for an agent to decide when to invoke it.

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