Delete Weather Log

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

Annotations already disclose destructiveHint=true and readOnlyHint=false, so the description's emphasis on 'cannot be undone' is redundant but not contradictory. The description adds the required parameter list and API endpoint, which provides some behavioral context beyond the annotations. No contradictions with annotations.

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 three sentences but contains repetition: 'permanently delete' and 'cannot be undone' are each stated twice. It could be more concise without losing clarity. Still, it is fairly short and front-loaded.

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?

The description provides the endpoint and API area, which adds useful context. However, it lacks details about the response (e.g., success/error codes) and potential error cases like attempting to delete a non-existent log. For a destructive tool, this would be helpful but is not essential.

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 coverage is 100% with clear descriptions for both parameters. The description lists required parameters but does not add significant new meaning beyond what the schema provides. For 'id', the schema already specifies the date format; the description does not enhance this.

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 it deletes a single Weather Log and permanently removes Daily Log records. It specifies the verb (Delete) and resource (Weather Log). However, it does not explicitly differentiate from the sibling tool 'delete_weather_log_project' which might target a different API version, so it loses a point for lack of sibling differentiation.

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 tells the user to use this tool for permanent deletion but provides no guidance on when to use this tool versus alternatives like other delete tools (e.g., 'delete_weather_log_project'). There is no mention of when not to use it or any context for selection.

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