log_diaper

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only says 'Log a diaper change' without stating that it creates a record, what side effects occur, whether permissions are required, or what the response contains. This is minimal to the point of being nearly tautological.

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 a single sentence that immediately states the action and object. There is no filler or redundant wording, so it earns full credit for conciseness and structure, even though it lacks substance elsewhere.

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 8 parameters, no annotations, and no output schema, the description is far too sparse to be complete. An agent cannot determine required input semantics, return values, or how this differs from related feeding/potty logs. More detail is essential.

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 description coverage is 0%, and the description adds no meaning for any of the 8 parameters. It does not explain what 'start' represents, why 'mode' is required, how child_uid is used, or how optional fields like color and consistency relate to diaper changes. The schema enums help, but the description itself is silent.

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 states a specific action ('Log') and resource ('a diaper change'), making the core purpose clear. However, with a sibling tool named log_potty, it does not explicitly differentiate between diapers and potty events, so it misses a chance to distinguish itself.

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?

There is no guidance on when to use this tool versus alternatives like log_potty or get_diaper_history. No context, prerequisites, or exclusions are provided.

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