watchpin_manual_pulse

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

No annotations are provided, so the description must carry the full burden. It only states 'pulse' and returns 'Confirmation,' omitting details like side effects, safety, or authorization needs. For a mutation-like action, more transparency is needed.

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: two sentences plus an Args list and Returns line. Every sentence is essential, front-loaded with the main action, and no waste.

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 simplicity of the tool (pulse a pin) and the presence of an output schema (implied by 'Returns: Confirmation'), the description is fairly complete. It could mention that it's intended for testing only, but overall it's sufficient.

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 0%, but the description adds meaningful semantics: pin is 'WatchPin number' and duration_ms is 'Pulse duration in milliseconds (default: 10)'. This explains the parameters well beyond the schema types.

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 tool's purpose: 'Manually pulse a WatchPin for testing.' It distinguishes from sibling watchpin tools (configure, enable, disable, etc.) by specifying it's for verifying hardware connections before automatic triggers.

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 gives context: 'Useful for verifying WatchPin hardware connections before setting up automatic triggers.' This implies when to use it (testing) but does not explicitly exclude other uses or name alternatives, so it's clear but not exhaustive.

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