Set target

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

Annotations already state readOnlyHint=false, openWorldHint=true, and destructiveHint=false. The description adds only URI examples and does not explain what state changes occur, whether active streaming is interrupted, or whether authentication or specific tuner states are required.

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 compact fragment with examples, front-loaded with the endpoint path and free of filler. It is appropriately terse, though its cryptic backtick formatting slightly reduces clarity rather than being verbose.

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 mutation tool with two required parameters, 0% schema description coverage, and no output schema, the description is too thin. It omits what the target controls, the meaning of the tuner parameter, side effects, and any operational caveats.

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%, so the description must carry parameter meaning. It gives examples for the `target` URI format and implies `tuner` is a numeric tuner index via `/tuner<n>/target`, but it does not explain the tuner's valid range, indexing convention, or constraints on the target value.

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 names the verb 'set' and the resource 'target' and gives the endpoint path plus URI examples, which helps infer it configures a tuner's output destination. However, it does not explicitly define what a 'target' is or distinguish this operation from the counterpart `hdhomerun_get_target`, leaving the purpose vague.

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 `hdhomerun_get_target`, `hdhomerun_stop_tuner`, or other setter tools. No prerequisites, exclusions, or context are provided.

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