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

With no annotations provided, the description carries the burden of behavioral disclosure. It does disclose the core mutating effects: renaming and hiding from slideshow. However, it omits behavior around frameId, whether updates are partial or full, permissions, and response/error behavior.

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?

A single front-loaded sentence with no filler: it states the action, the resource, and the specific supported behaviors. Every part 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?

For a 4-parameter mutation tool with no annotations and no output schema, this one-liner is not complete enough. It leaves frameId semantics undefined and gives no indication of return values or error behavior, even though it covers the most common rename and hide use cases.

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 only 25%, so the description must compensate. It helps by mapping 'rename' to title and 'hide from slideshow' to exclude_from_slideshow, but frameId remains completely unexplained in both the schema and the description, making the compensation incomplete.

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 the verb 'Update' and resource 'photo album', then concretely lists the supported operations ('rename, hide from slideshow'). This clearly distinguishes it from sibling album tools like create_album, delete_album, add_to_album, and remove_from_album.

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 parenthetical provides clear intended usage contexts: renaming an album or hiding it from slideshow. It does not explicitly mention alternatives or exclusions, but the stated operations give an agent enough context to decide when this tool is appropriate.

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