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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false. The description adds nothing about task creation, async behavior, polling, cost, or auth. Its only quasi-technical content is a truncated 'Suggestions for How to Shoot:' with no content following it.

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?

Three sentences of promotional prose occupy the entire description, ending mid-thought at 'Suggestions for How to Shoot:'. Nothing is front-loaded about the operation, and no sentence 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?

An output schema exists so return values need not be described, but for a tool requiring a template_id sourced from a sibling templates endpoint, the description supplies none of the operational context needed to invoke it correctly. It reads as an ad rather than a tool definition.

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 50% and the description contributes zero parameter meaning — template_id, src_file_url/src_file_id, and polling are never mentioned. The dangling 'Suggestions for How to Shoot:' lead-in is exactly where input guidance should be and it is empty.

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 text is marketing copy ('bouncy ringlets, loose waves, or a bold curly statement') that restates the title rather than stating a functional verb+resource. It never says plainly that it applies a wavy/curly hairstyle to a submitted photo, and it gives no differentiation from the many sibling try-on tools (AI-Hair-Style-Virtual-Try-On, AI-Hair-Volume, AI-Hair-Extension).

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?

No when-to-use, when-not-to-use, or alternative is named. Critically, nothing tells the agent it must first call AI-Wavy-Hair-Virtual-Try-On-Templates to obtain a valid template_id, nor how this differs from the other hair/style try-on siblings.

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