sleep_list_sleep

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

Since there are no annotations, the description carries the burden of behavioral disclosure. The word 'List' correctly implies a read-only operation, and 'optional filters' implies that omitting filters returns all records, but no details about pagination, result ordering, or default behavior are given. The description does not contradict any annotation because none are provided.

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?

A single sentence conveys the verb, resource, and variability (filters). It is front-loaded and every word contributes. There is zero fluff.

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 schema fully documents 10 optional parameters, and the context signals indicate an output schema exists, so agents can infer the return shape. However, the description does not explain default behavior when no filters are supplied, or whether filters are AND-combined. Given the parameter richness (10 filters) and no annotations, a slightly richer description would help the agent know which combinations are sensible, but the schema and the simple verb 'List' carry the main load.

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 100% and the description mentions generic filters, but the description itself does not add parameter-level details. The baseline for full schema coverage is 3, and this gets a 4 because the description's generic 'optional filters' correctly indicates that all parameters are optional and that filters narrow results rather than changing the response schema.

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 clear verb ('List') and resource ('sleep records') and mentions filters. It is distinguishable from sibling tools like sleep_create_sleep or sleep_update_sleep because it is the only list operation on the sleep resource.

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 implies the tool is for querying/reading sleep records and names optional filters, but provides no explicit guidance about why to choose this over other sleep tools (e.g., create/update/delete). There are no alternative tools for listing sleep records, so differentiation is less critical, but the 'when to use' context is still mostly implied rather than explicit.

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