get_agp_report

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

No annotations are provided, so the description must disclose behavioral traits. It mentions Dexcom API and persistence layer integration but does not clarify safety (e.g., read-only status), side effects, output format, or failure modes. This is a significant gap for a tool with no annotation support.

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 concise and front-loaded with the main purpose, followed by useful clinical context and parameter explanations. Every sentence contributes, though the Args section could be tightened.

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?

With no annotations and no output schema, the description fails to explain important aspects like what the report return value looks like, how to handle data source selection, and any prerequisites or side effects. It covers the core purpose but lacks necessary operational details for correct invocation.

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 descriptions are absent (0% coverage), so the Args section adds meaningful semantics: minutes has range and default, and data is described as optional external readings. However, 'persistence layer integration' is vague and could be clearer.

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 the tool generates an Ambulatory Glucose Profile (AGP) report, a specific clinical standard. It explains what the report shows (glucose percentiles by time of day) and is easily distinguished from sibling tools that fetch raw glucose readings or statistics.

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 clinical context ('used by endocrinologists') implies when to use this tool, but there is no explicit comparison to alternatives or statements about when not to use it. Sibling tools like get_statistics or get_glucose_readings are not mentioned.

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