skylight_list_albums

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

The readOnlyHint annotation already indicates this is a safe read operation, and the description is consistent with that. The description adds no deeper behavioral context such as pagination, sorting, or what happens when frameId is omitted, but the annotation lowers the burden.

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 a single, focused sentence with no redundant wording. It front-loads the action and resource clearly, making it easy for an agent to parse quickly.

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 straightforward read-only list tool with one optional parameter, the description is nearly adequate, but it leaves the role of frameId ambiguous and does not describe the return value or output shape. An agent could still use it correctly based on the tool name and schema, but the description alone is thin.

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?

The schema has one parameter, frameId, with 0% description coverage, so the description must compensate. It mentions 'the Skylight frame' but never explicitly explains that frameId identifies which frame's albums to list, nor what happens when it is omitted. The parameter name carries most of the meaning.

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 clearly states the action ('List') and the resource ('photo albums on the Skylight frame'), which distinguishes it from album-mutating siblings like create_album, delete_album, and update_album. It does not explicitly enumerate the scope or say 'all albums', so it stops just short of a top score.

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 verb 'List' implies this is the tool to use when the agent needs to retrieve existing albums, and it is distinct from create/update/delete album tools. However, it provides no explicit when-to-use or when-not-to-use guidance and does not mention alternatives such as skylight_list_frames or skylight_set_device_album.

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