update_config_mediamanagement_by_id

Idempotent

Update media management settings in Radarr by providing the configuration ID and the updated payload. Modify existing media management configurations directly.

Instructions

PUT /api/v3/config/mediamanagement/{id}

Args: id: Path parameter. body: Request payload. Read the matching GET or the /schema endpoint first to see the fields this resource expects.

TDQS

B3.4/5.0
Behavior2/5

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

Annotations already establish readOnlyHint=false, idempotentHint=true, and destructiveHint=false. The description adds no behavioral context beyond what the name and annotations convey: no side effects, replacement semantics, authorization needs, or error behavior. It is not contradictory, but it does not enrich the behavioral picture.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded: purpose first, then the endpoint, then arguments, then a practical prerequisite. Every sentence earns its place; there is no repetition of structured schema data or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-parameter update endpoint, the description gives the method, path, argument roles, and a clear strategy for discovering body fields. It is complete enough for an agent to invoke correctly, especially since annotations cover idempotency and non-destructiveness and an output schema is present.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

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 does label id as a path parameter and body as the request payload, and it directs the agent to the matching GET or /schema endpoint for the actual field list. This is helpful but still leaves the body fields unspecified, so it only partially compensates for the missing schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb and resource: 'Update MediaManagementConfig.' The PUT path further clarifies it is the id-based update endpoint for media management configuration. It doesn't explicitly distinguish itself from the many sibling update_config_*_by_id tools, but the resource name and URL make the target unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use it: when updating a MediaManagementConfig by id. It also gives a useful precondition: 'Read the matching GET or the /schema endpoint first to see the fields this resource expects.' However, it does not explicitly mention alternatives or conditions for choosing another tool, so the guidance is more implied than explicit.

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