watchpin_configure

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

With no annotations, the description carries full burden. It explains the configuration action and return value, but does not mention prerequisites (e.g., hardware availability) or error handling. Adequate but not detailed.

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 well-structured with clear Args and Returns sections. It is concise, front-loaded with a summary, and each sentence adds value without redundancy.

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?

For a simple configuration tool, the description covers main behavior and return type. It could mention error cases (e.g., invalid pin), but given the output schema presence and straightforward nature, it is nearly complete.

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 description adds substantial meaning beyond the schema: it explains each trigger condition ('break', 'go', etc.) and defines polarity ('active high', 'active low'). Schema coverage is 0%, but description fully compensates.

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 'Configure a WatchPin to trigger on specific events,' specifying the verb and resource. It distinguishes from sibling tools like watchpin_enable and watchpin_disable by focusing on configuration.

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 context is implied but not explicitly stated. No guidance on when to use this vs. watchpin_enable or other WatchPin tools is provided, leaving it to the agent's inference.

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