pushover_cancel_emergency

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

No annotations exist, so the description carries full burden. It only states cancellation of an outstanding notification, but does not disclose effects on users, whether the receipt becomes invalid, or any return behavior. The minimal description lacks sufficient behavioral detail.

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 (one sentence), but at the expense of completeness. For a tool with three required params and no annotations, it is too sparse to be considered well-structured. It could be more informative while remaining concise.

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 complexity (3 required params, no output schema, no annotations), the description is incomplete. It lacks parameter explanations, return value information, and usage context. The single sentence does not adequately equip an AI agent to correctly invoke the tool.

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?

The input schema has 0% description coverage for parameters, and the description does not explain any of the three required parameters (app_token, user_key, receipt). With no compensation from the description, the agent receives no guidance on what these parameters mean.

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 the verb 'cancel' and the resource 'outstanding emergency Pushover notification', including the timing condition 'before it expires'. It effectively distinguishes from sibling tools like pushover_send_notification (create) and pushover_get_receipt (check status).

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 implies usage when an emergency notification needs to be cancelled, but does not explicitly state when to use this tool versus alternatives, nor does it mention prerequisites (e.g., needing a receipt from get_receipt) or exclusions.

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