Set ir target

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

Annotations already state readOnlyHint=false, destructiveHint=false, openWorldHint=true, so the write semantics are partly covered. The description adds nothing about whether the target persists, whether a device/IR blaster must be reachable, or what the call returns on success — meaningful gaps for a mutating 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?

Brevity here is under-specification rather than conciseness: a backticked path fragment and a format placeholder, with no complete sentence stating the action. Front-loaded but fragmentary.

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?

The tool is simple (one string param, no output schema), but the description never explains what the endpoint does beyond naming it, nor the side effects of setting an IR target. For a non-read-only tool with zero schema documentation, more context is needed.

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 0% for the single required parameter, so the description must carry the burden — and it does supply the one genuinely useful detail, the `<ip>:<port>` format. It still omits validation rules, default port, and what happens if the target is unreachable, so it only partially compensates.

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 text "`/ir/target` set" essentially restates the tool name (set_ir_target) in endpoint form, and the only added fragment is the value format. It never says what an IR target is or what setting it accomplishes on the device, so an agent gains little beyond the name.

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 when-to-use guidance, no mention of the obvious counterpart (hdhomerun_get_ir_target) or how this differs from the many other hdhomerun_set_* tools. The agent is left to infer usage purely from the name.

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