set_channel

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

No annotations provided; description implies a state change (tuning) but does not disclose side effects, requirements (e.g., TV must be on), or whether the channel switches immediately. Minimal behavioral context.

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?

Single sentence with no redundant information. Could be slightly expanded without losing conciseness, but currently no waste.

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 simple one-parameter tool with no output schema, the description misses key context such as how to obtain a valid channelId and any prerequisites. The existence of sibling list_channels implies a workflow, but the description does not link to it.

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 provides no description for 'channelId' (0% coverage). Description adds 'by its channelId' but does not explain what a channelId is, its format, or how to obtain it (e.g., from list_channels). Insufficient for a parameter with zero schema documentation.

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?

Description clearly states the action (Tune) and resource (channel) via a specific identifier (channelId). It distinguishes from siblings like channel_up/down (relative changes) and list_channels (listing).

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?

No guidance on when to use this tool versus alternatives (e.g., channel_up/down for relative tuning, list_channels to obtain channelIds). Does not mention prerequisites or exclusions.

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