send_presence

Destructive

Set your WhatsApp online availability status to 'available' or 'unavailable' to control when others see you as online.

Instructions

Set the user's own online availability. Different from send_typing, which affects per-chat composing presence.

Behavior4/5

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

Annotations indicate destructiveHint=true and readOnlyHint=false, which the description aligns with by implying a state change. The description adds context about the scope (affects overall availability vs. per-chat presence), which is valuable beyond annotations. However, it doesn't detail side effects like rate limits or confirmation mechanisms.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences with zero waste: the first states the purpose, and the second provides critical sibling differentiation. It's front-loaded and appropriately sized.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (one parameter, no output schema), the description covers purpose and usage well. However, it lacks details on behavioral aspects like error conditions or response format, which could be helpful despite annotations.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the parameter 'state' fully documented via enum values. The description doesn't add meaning beyond the schema, such as explaining the implications of 'available' vs. 'unavailable', so it meets the baseline for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Set the user's own online availability') and resource ('user's own'), and explicitly distinguishes it from a sibling tool ('Different from `send_typing`'). This provides precise verb+resource differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly states when to use this tool versus an alternative ('Different from `send_typing`, which affects per-chat composing presence'), providing clear context for selection among siblings.

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