get_setting

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

With no annotations, the description carries the full behavioral burden. It usefully describes the return content as the current value, its source, and the preset value, but it does not explicitly state that the operation is read-only, nor does it mention permissions, errors, or other operational constraints.

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 efficient sentence with no redundant filler. It is appropriately sized for a simple getter, though it front-loads the return characteristics rather than an explicit action verb.

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 simple one-parameter getter without an output schema, the description partially covers return values (current value, source, preset value). However, it omits key format details and any usage context, so the agent is not fully equipped to invoke it correctly without guessing the key syntax.

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 single required parameter 'key' has 0% schema description coverage, so the description should compensate. It only hints at setting categories ('print/filament/printer') but gives no key format, examples, or naming conventions, leaving the parameter semantics largely unexplained.

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 a specific resource (a print/filament/printer setting) and what will be returned (current value, origin, preset value). It implies a read operation through 'Current value' and is distinguishable from set_setting/reset_setting, though it does not explicitly name those 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 guidance on when to use this tool versus alternatives such as set_setting or reset_setting. The description only states what the tool returns, leaving the agent to infer its role from the name and context.

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