create_alias

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

No annotations are provided, so the description carries the burden. It states it creates a local exception and is user-managed. However, it does not disclose side effects, prerequisites (e.g., series must exist), or idempotency. The existence of an output schema is not leveraged in the description.

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 succinct but could be slightly more concise. It uses two paragraphs: a short summary and a longer explanation. The Args section is well-structured. No unnecessary sentences, but some redundancy exists between the first sentence and the second paragraph.

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 3 parameters and an output schema, but no annotations. The description adequately covers parameters and purpose but lacks information about return values or error conditions. Given the presence of an output schema, the omission is less critical, but the description is still incomplete for a new user.

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 Args section provides clear, specific explanations for each parameter: series_slug format, name purpose, and season optionality with default behavior. This compensates for the 0% schema description coverage, adding significant meaning beyond the parameter names.

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 states the tool creates a local scene exception (alias) for a series. The verb 'create' and resource 'alias' are specific. It distinguishes from siblings like 'delete_alias' and 'get_aliases' by implying creation.

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 explains the tool's purpose: enabling Medusa to recognize alternative release titles. It notes the limitation that only local exceptions can be created. However, it does not explicitly state when not to use or suggest alternatives like relying on other scene exceptions.

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