sonarr_create_indexer_action

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

Annotations already indicate readOnlyHint=false, and the description adds an explicit 'WRITE: modifies your Sonarr instance' label. This provides some confirmation of the write nature but does not disclose specific side effects, required permissions, or response behavior beyond that, which is minimal additional context beyond annotations.

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 very short and front-loaded with the write warning, but the brevity borders on under-specification. It is not verbose, yet it sacrifices necessary content for conciseness.

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 tool with a nested 'body' object and numerous sibling operation types, the description is severely incomplete. It does not define what an indexer action is, what the body should contain, or how this differs from other indexer-related mutations, making the context insufficient.

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%, and the description does not compensate by explaining the required 'name' or optional 'body' parameters. The agent receives no semantic guidance for constructing a valid request, especially the purpose of the nested body object.

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 'Create indexer action' is essentially a tautology of the tool name, providing no explanation of what an indexer action is or how it differs from creating an indexer or running tests. The added 'WRITE: this modifies your Sonarr instance' addresses side effects but not the core purpose.

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 when-to-use context is provided. The description does not mention alternatives or indicate when this action should be chosen over sibling tools like sonarr_create_indexer or sonarr_create_indexer_test, leaving the agent without selection guidance.

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