skylight_remove_from_album

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

Annotations indicate readOnlyHint=false and destructiveHint=false, so the description doesn't need to restate those, but it also adds no behavior beyond the raw action. It does not disclose whether removal is reversible, whether it only severs the album association rather than deleting the underlying messages, what side effects occur, or whether any permissions are required.

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, front-loaded sentence with no filler or repetition. It earns its place but is too terse to fully support the tool's semantics.

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 mutation tool with three parameters, no output schema, and zero parameter documentation, the description is under-specified. It leaves unclear what the response is, whether the operation affects only album membership, and how frameId modifies the behavior.

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 compensate, but it only loosely maps to the parameters ('messages/photos' suggests message_ids and 'albums' suggests album_ids). It provides no detail about the format of the IDs, the role of optional frameId, or how the two arrays interact.

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 uses a specific verb ('Remove') and explicitly names the resource ('messages/photos') and target ('albums'). It clearly distinguishes this operation from siblings like add_to_album, delete_album, and delete_messages without requiring the agent to open their schemas.

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 description provides no guidance on when to use this tool versus alternatives. It does not mention that this is the opposite of skylight_add_to_album, nor does it explain when to use it instead of skylight_delete_message or skylight_delete_album. Context must be entirely inferred from the tool name.

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