radarr_update_config_host

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

The description explicitly states 'WRITE: this modifies your Radarr instance,' adding behavioral context beyond the annotations (which only indicate not read-only). However, it does not disclose specific side effects, required permissions, or whether changes are reversible. With annotations already covering basic safety, this is adequate but not rich.

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 extremely concise with two short sentences, front-loaded with the action. No wasted words, but it may be under-specified for the tool's complexity.

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?

Despite having an output schema, the description lacks context on how to use the tool, what the parameters mean, and what constitutes a host update. The tool is a simple update operation but still requires more detail for an agent to invoke it correctly.

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?

The input schema has two parameters (id and body) with no descriptions, and schema coverage is 0%. The description provides no explanation of what id represents or what body should contain, offering zero value for parameter understanding.

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 'Update host' with a clear verb and resource, and the WRITE label clarifies its action. However, it does not explicitly differentiate from sibling tools like radarr_update_config_downloadclient, relying on the tool name for that. It is clear but minimal.

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 implies usage for updating host settings, and the WRITE warning suggests caution, but there are no explicit scenarios, prerequisites, or alternatives provided. No guidance on when to use this vs. get_config_host.

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