sleep_create_sleep

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

No annotations are provided, so the description carries the full burden of disclosing behavior. 'Record' implies creating a new sleep entry, but the description does not state whether it inserts a new record, overwrites anything, or how it relates to timers versus explicit times. It adds little beyond the tool name.

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 focused sentence with no filler and front-loads the action. It is efficient, though it is so minimal that it may be under-specified rather than optimally concise.

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?

The input schema covers every parameter and an output schema exists, so the tool is broadly invocable from structured data. However, with no annotations and no usage or behavioral context, the description alone leaves meaningful gaps about when to select this tool and what side effects to expect.

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 100%, and the schema already documents all six parameters, including timer_id, nap, and notes semantics. The description itself adds no parameter-specific meaning, which aligns with the baseline-3 expectation for high schema coverage.

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 names a specific action ('Record') and a concrete resource ('a sleep session'), which clearly matches the create operation and distinguishes it from the sibling sleep update/delete/list tools. It is brief but unambiguous.

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 no guidance on when to use this tool versus sleep_update_sleep or any other sleep-related sibling. There are no prerequisites, exclusions, or alternative routing, so usage is only implicitly inferred from the name and the word 'Record'.

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