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

No annotations are present, so the description must carry the full behavioral disclosure burden. It states the import action and accepted formats but does not mention side effects (creating/overwriting templates), validation behavior beyond the validate parameter, network/auth expectations, or failure modes. An import tool with no safety annotations needs more behavioral context.

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 with the core verb, followed by a clean bulleted list of supported URL types. The version note is brief and contextual, not harmful, though it adds limited value.

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?

With an output schema present and a moderately simple 3-parameter tool, the description covers accepted input sources well. It falls short on side-effect transparency and leaves user_uuid undefined, so it is adequate but not fully complete.

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 coverage is 67% with url and validate already documented, and the description adds useful URL-type examples for url. However, user_uuid has no schema description and the description does not explain it, leaving a gap for one of three parameters.

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 opens with a specific verb and object ('Import a prompt template from a URL') and immediately narrows the resource to external URLs (GitHub Gist, raw file, HTTPS JSON/YAML). This makes it clearly distinguishable from sibling template tools such as export_prompt_template, get_prompt_template, or register_custom_template.

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 supported URL list and 'Unified Prompt Templates feature' note imply this tool is for bringing external templates into the system, but no explicit when-to-use or when-not-to-use guidance is given versus register_custom_template or export_prompt_template. The agent must infer the tool's role from its name and the URL examples.

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