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

Annotations already declare readOnlyHint=false and destructiveHint=true; the "[write]" prefix is consistent and reinforces that. Beyond that, the description adds only the lifecycle context (albums get filled by other tools) and nothing about permissions, whether kind is immutable after creation, or what happens on duplicate titles. Adequate but thin given this is flagged destructive.

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?

Two tight sentences with the write-nature flagged first, then purpose, then valid kind values, then downstream usage. Nothing is padded. Minor cost: the phrasing "Pass the answered images_album_uuid as images_album_uuid" is awkward and refers to a parameter this tool does not have.

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?

For a 3-parameter tool with no output schema, the description covers the essentials: what it produces, the valid kind values, and how the return value is consumed downstream — which compensates for the missing output schema. It lacks scope details (account/workspace ownership, uniqueness constraints) but nothing that would cause a mis-invocation.

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 — and it does supply the meaningful part: `images_album_kind` takes MANUAL or STORYBOARD, values that appear nowhere in the schema (no enum is defined). Title and description params are self-evident from their names and go unmentioned, which is acceptable.

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?

States a specific verb+resource ("Create an album") and immediately defines the resource as "a named group of pictures," so an agent knows exactly what object is produced. It also names the downstream consumers (create_character_image / create_promo_image), which implicitly separates it from plain create_image. It stops short of contrasting with near-siblings like create_storyboard, which is why it isn't a 5.

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?

Gives real ordering context: create the album first, then pass the returned images_album_uuid into create_character_image / create_promo_image to populate it. That tells the agent where this tool sits in a workflow. There is no explicit "when not to use" (e.g., vs create_storyboard), so it falls short of a 5.

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