millumin_set

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

No annotations are provided, so the description must carry the behavioral burden. 'Set' implies mutation and the default target is disclosed, but permissions, side effects, reversibility, error behavior, and return behavior are all omitted.

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 compact and front-loaded: the core operation comes first, followed by target syntax and property examples. Every clause contributes directly to invocation.

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?

It covers target and property syntax well, and the schema fully documents the value parameter. But with no annotations and no output schema, the description leaves mutation side effects, error behavior, and sibling selection guidance unaddressed.

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 coverage is 100%, so the baseline is 3. The description earns a bump by adding target forms beyond the schema example ('light:<name>', 'index:<n>', element name) and extra property paths such as 'position/x' and 'media/speed'.

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 states a specific verb and resource: 'Set a property on a target.' It adds property examples that clarify the kind of operation, but it never differentiates this tool from siblings such as millumin_action or millumin_send_raw.

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?

Usage is implied by the operation name, and the target-default sentence helps invocation. However, the description never states when to choose this over millumin_action, millumin_send_raw, or other siblings, nor does it give prerequisites or exclusions.

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