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

Annotations already declare readOnlyHint, idempotentHint and non-destructive, so the safety profile is covered. The description adds a genuine policy constraint (never accept photos here, consent handled off-tool), but says nothing about what the returned link is, whether it expires, or what happens if `stage`/`topic` are omitted.

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 short sentences, the use case comes first and the hard constraint follows. Nothing is filler, though the opening clause is grammatically tangled enough to slow comprehension slightly.

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?

No output schema exists, so the description should explain what the link actually is and how the caller should present it; it only says 'website creation link'. Combined with the unexplained `stage` and `topic` parameters, an agent has to guess about most of the call's surface.

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 must carry the load. It implicitly defines `kind` via 'one person / two separate people / a pet photo', but `stage` (five enum values) and `topic` (160-char string) are never mentioned, leaving two of three parameters entirely undocumented.

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?

Names a concrete output (a website creation link) scoped to three input cases, and the mapping 'one person / two separate people / a pet photo' corresponds to the solo/duo/pet enum values. Wording is a bit awkward ('give the user a website creation link') and it never says explicitly that it creates nothing itself, but an agent can tell it apart from create_character_video_order.

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?

Provides an explicit exclusion — photos, screening and consenting-adult declarations must happen on raploom.com and must never be accepted through this tool. That is a real when-not-to rule, though it does not disambiguate against sibling create_character_video_order or get_order_status.

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