delete_price_alert

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

The annotations already provide destructiveHint=true, so the destructive nature is disclosed. The description adds the authentication requirement (IWMM_API_KEY), which is not in annotations. However, it does not elaborate on consequences (e.g., irreversibility) or whether other data is affected.

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 concise with two short sentences. The primary action is front-loaded ('Delete a price alert by ID'), and the second sentence adds a crucial prerequisite. No unnecessary words.

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 simplicity (one parameter, no output schema), the description is adequate but incomplete. It lacks return value information, error handling (e.g., if ID not found), and confirmation of irreversibility. Still, the core purpose and requirement are clear.

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 says 'by ID' but does not explain what the ID represents (e.g., the ID from list_price_alerts) or provide any format or source. The parameter 'id' remains minimally documented.

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 'Delete a price alert by ID' – a specific verb ('Delete'), a distinct resource ('price alert'), and how it's identified ('by ID'). This distinguishes it from siblings like create_price_alert and update_price_alert.

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 on when to use this tool versus alternatives (e.g., when a price alert is no longer needed). It only mentions 'Requires IWMM_API_KEY' as a prerequisite, but does not explain usage context, conditions, or what happens if the ID is invalid.

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