blink_multi

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

No annotations are provided, so the description carries the burden. It discloses the core behavior (periodic on/off) but omits details like how to stop blinking, what happens to bits with mask=0 (though schema covers that), or whether this overrides existing configurations. Minimal but not misleading.

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?

A single, front-loaded sentence that states the tool's purpose and mode of operation without redundancy. Every word adds value.

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 control tool with no annotations, output schema, and 4 parameters, the description is adequate but lacks usage guidance, cancellation semantics, and how it interacts with other functions like group or address. The schema provides parameter details, but the description alone is somewhat sparse for safe 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 coverage is 100%, with rich descriptions for mask, time, group, and address. The description adds no additional parameter meaning beyond mentioning 'by bit' and 'multi-channel', so baseline 3 is appropriate.

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 a specific action: 'blink' multiple relay channels periodically by bit mask ('多路闪烁（按位）...周期性通断'). It implicitly distinguishes from single-channel blinking (blink_single) and momentary operations, with a clear verb+resource+scope.

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 gives clear context: for periodic multi-channel toggling using a bit mask. It does not explicitly state when not to use it, but the context is sufficient to infer appropriate use relative to sibling tools like blink_single and momentary variants.

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