hda_create

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

With no annotations provided, the description carries the full burden. It discloses that the operation is mutating and outlines the internal validation and creation calls, plus a response cap via apply_response_cap. However, it does not mention permissions, reversibility, or failure behavior when canCreateDigitalAsset() returns false.

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 short but information-dense, with a clear purpose statement and code-like steps. It is well-structured and front-loaded, though the parenthetical '(add-hda-management-tools, MUTATING)' adds context without excessive length.

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 description covers the main workflow but lacks details about return values, error handling, or prerequisites beyond the canCreateDigitalAsset check. With no output schema, the response format is not explained, leaving the agent with an incomplete picture for a create operation.

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 schema has 0% description coverage, so the description must explain parameters. It explains that 'label' maps to the description parameter, but it references 'hda_file_name' which does not appear in the schema, and it does not clarify the roles of 'node_path' or 'save_path'. This creates ambiguity.

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 '从节点创建 HDA' (create HDA from node), identifying a specific verb, resource, and scope. It also labels the operation as MUTATING, distinguishing it from read-only HDA tools like hda_get or hda_list.

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 provides a procedural sequence (canCreateDigitalAsset() then createDigitalAsset()) but does not explicitly contrast with sibling tools such as hda_install or update_hda. There is no explicit 'when not to use' guidance, though the 'from node' phrase implies a specific use case.

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