skylight_delete_message

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

With no annotations provided, the description bears the full burden of behavioral disclosure. It only states the basic action, omitting critical details such as whether deletion is permanent, irreversible, or requires authentication. This is insufficient for safe usage.

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 extremely short and to the point, which is concise but not structured. It could be expanded to include essential details without becoming verbose. It is appropriately sized for a simple tool but lacks important elements.

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?

Given the tool's complexity (2 parameters, no output schema, 0% schema coverage), the description is severely incomplete. It omits parameter explanations, behavior details, and any return value information. The tool is not adequately documented for an agent to use correctly.

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%, yet the description provides no clarification for the parameters 'id' and 'frameId'. It does not explain what they represent (e.g., message ID, frame ID) or how they should be used. The description fails to add meaning beyond the schema.

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?

Description clearly states the action 'Delete' and the resource 'frame message/photo', which is specific. However, it does not explicitly differentiate from the sibling tool skylight_delete_messages (plural), leaving ambiguity about whether this deletes a single item while the other deletes multiple. The name helps, but the description does not address it.

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?

No guidance is provided on when to use this tool versus alternatives like skylight_delete_messages, or any prerequisites or context for deletion (e.g., permissions required). The description lacks usage context entirely.

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