create_indexer_action_by_name

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

Annotations already indicate idempotentHint=true and readOnlyHint=false, and the description does not contradict them. It adds context about the endpoint and instructs the agent to inspect the schema before sending a body, but it does not disclose effects beyond creating an indexer, auth requirements, or response behavior.

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 compact and front-loaded: it states the operation, gives the endpoint, and then lists the two arguments with a clear instruction for handling the payload. Every line earns its place.

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 2-parameter creation endpoint with an output schema and existing annotations, the description covers the essentials: endpoint, parameter roles, and how to discover the body shape. It is slightly incomplete in not clarifying the difference from sibling indexer creation tools, but the core invocation context is present.

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 carries the burden for parameter meaning. It identifies name as a path parameter and body as the request payload, and it tells the agent to fetch the matching GET or schema endpoint to learn the body's expected fields. This is meaningful guidance for an open/opaque 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 clearly identifies the action as 'Create Indexer' and gives the exact REST endpoint, so an agent knows the verb and resource. However, it does not explain what distinguishes this from the sibling create_indexer tool or what 'action_by_name' means.

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 by showing the POST endpoint and stating that a payload is required. It gives the useful prerequisite to read the matching GET or /schema endpoint first, but it does not explicitly state when to use this tool versus alternatives such as create_indexer.

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