skylight_add_to_album

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the add action and omits whether additions are idempotent, whether messages are moved or copied, what happens on invalid IDs, or any permission requirements.

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 sentence with no wasted words and the core verb/object is front-loaded. It is concise, though it sacrifices richness for brevity.

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?

With no annotations, no output schema, and no parameter descriptions, a one-line description leaves frameId, return behavior, error cases, and add semantics undefined. This is acceptable for a very simple tool but not fully sufficient for robust agent 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?

With 0% schema description coverage, the description's mention of 'messages/photos' and 'albums' provides the only meaning for message_ids and album_ids. However, the optional frameId parameter is completely unexplained, and the relationship between the two required arrays is left implicit.

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 states a specific action ('Add') and exact targets ('messages/photos to albums'). This clearly separates it from siblings like skylight_remove_from_album and skylight_create_album, so an agent can distinguish the tool without opening its schema.

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 usage context is only implied by the verb 'Add'. It does not explicitly state when to prefer this tool over alternatives or mention any exclusions, though the intended use case is reasonably inferable from the action.

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