skylight_remove_from_album

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

There are no annotations, so the description carries the full behavioral burden. It only restates the operation without disclosing that the underlying messages are not deleted, whether removal is reversible, what permissions are needed, or what happens to messages already on frames. The phrase 'from albums' hints at non-destructive removal but does not make it explicit.

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 by stating the action and scope clearly, without boilerplate.

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 0% schema description coverage, this minimal description leaves important context missing: the role of frameId, the side effects of removal, and error/disambiguation behavior. It is insufficient for reliable invocation in ambiguous situations.

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. It maps album_ids and message_ids to the operation, but frameId is entirely unexplained and no parameter-level detail is provided. An agent cannot tell what frameId does or how the arrays are interpreted beyond their names.

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'), names the resource ('messages/photos'), and names the container ('albums'), which makes the operation unambiguous. It also distinguishes itself from sibling tools like skylight_delete_messages and skylight_delete_album by scoping the action to album membership rather than deletion.

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 is implied by the direct statement 'Remove messages/photos from albums' — an agent can infer it is the tool to call when messages should leave an album. However, it gives no explicit conditions, prerequisites, or alternatives such as when to prefer skylight_delete_messages over this tool.

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