cleanuparr_update_arr_config

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

Annotations include destructiveHint: true, and the description's 'Replace' confirms destructive behavior. It adds value by implying the entire config is overwritten, not merged, and gives a typical content hint. However, it does not disclose other consequences like whether unmentioned fields are lost or if a restart is needed.

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 sentence that front-loads the primary action and includes a useful example. It is concise and efficient, though it omits critical details that would make it more complete.

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 has a nested config object and a destructive annotation, but the description does not explain how to construct the config or how arr_type is used. An output schema exists, so return values are not needed, but the input semantics are insufficient for reliable invocation without additional context.

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 compensate. It implies 'config' is the replacement object and 'arr_type' identifies the *arr type, but it does not enumerate valid arr_type values or specify the expected structure of the config object, leaving the agent to guess.

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 uses the verb 'Replace' with the resource '*arr config', making it clear that the tool overwrites a configuration object. The phrase 'normally containing failedImportMaxStrikes' provides a concrete example of the config content. It is reasonably distinct from sibling tools like update_arr_instance or update_general_config, though it doesn't explicitly call out those alternatives.

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 update_arr_instance or other update_*_config tools. The description only says 'normally containing failedImportMaxStrikes,' which hints at a typical use case but does not state when to choose this tool or when to avoid it.

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