balena_set_device_note

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

The description discloses no behavior beyond what the annotations already signal. It does not say whether the note is replaced, appended, or cleared, nor does it mention permissions, return behavior, or side effects. The annotations are not contradicted, but the description adds no transparency value.

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 single sentence is concise and front-loaded, but it is under-specified rather than usefully concise. There is no structural breakdown or additional context that helps an agent invoke the tool correctly.

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 mutating tool with two required parameters and no output schema, the description leaves the behavioral contract unclear. It provides no overwrite semantics, no device-targeting context, and no sense of what 'set' means in the product domain, making it barely sufficient to identify intent but not sufficient for confident invocation.

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?

Schema description coverage is 0%, and the description names neither parameter. It makes no attempt to explain that device_id identifies the target device or that note is the text payload, so it completely fails to compensate for the schema gap.

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 is a near-verbatim restatement of the tool name ('Set a device note.'), offering no additional detail about what a device note is or how setting it behaves. It names a resource, but the purpose semantics are essentially provided by the tool name itself.

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 about when to use this tool rather than related mutations such as balena_set_release_note, balena_update_variable, or balena_create_tag. No context, prerequisites, or exclusions are provided.

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