get_lifestyle_logging_data

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

With no annotations, the description carries the full burden of behavioral disclosure. It states that the tool returns lifestyle logging data and specifies the expected date format, which is useful. However, it does not describe output structure, empty-data behavior, or explicitly confirm read-only semantics beyond the 'Get' verb.

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 short and front-loaded with the main action and scope. The second sentence adds some context about the purpose of lifestyle logging data but is somewhat generic; overall, it is appropriately sized without wasted 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?

For a simple one-parameter getter with an output schema, the description is minimally adequate. However, 'lifestyle logging data' is left undefined, and there is no context about how this differs from other getters, which matters given the large sibling toolset.

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 schema only provides 'date' as a required string with no description, so the description's 'Date in YYYY-MM-DD format' is essential and adds meaningful semantic value. It fully compensates for the 0% schema description coverage for this single parameter.

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 a specific verb ('Get') and resource ('lifestyle logging data') scoped to a specific date. It is easy to understand what the tool does, though it does not explicitly differentiate it from the many other date-based getters in the sibling list.

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 is provided about when to use this tool versus alternatives like get_sleep_data, get_steps_data, or other get_* tools. The only context is 'for a specific date', which implies a narrow lookup but does not help an agent choose between related tools.

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