get_sleep_by_id

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

No annotations are provided, so the description carries the full behavioral burden, yet it only restates that a single record is returned. Nothing is said about not-found/error behavior, permissions, or the nature of the returned document — though 'Get' does weakly imply a safe read.

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, front-loaded sentence with no filler; the verb and resource come first and nothing is redundant.

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 one-parameter read with no output schema, the description is minimally sufficient to invoke the tool correctly. It is thin on intent-signaling against the many similar sleep/list siblings, but nothing critical to correct invocation is missing.

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 single document_id parameter is already documented in the schema, so the description adds no format or semantics beyond it. Baseline 3 applies when the schema does all the work.

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?

States a specific verb (Get), resource (sleep document) and scope (single, by unique ID), which lets an agent distinguish it from list-style siblings like get_sleep or get_daily_sleep. It stops short of explicitly naming which sibling it competes with or clarifying the difference between a 'sleep document' and a 'daily sleep' record.

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 get_sleep, get_daily_sleep, or get_daily_sleep_by_id. The 'by_id' naming convention implies retrieval by identifier, but no explicit conditions, prerequisites, or alternatives are stated.

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