garmin_get_nutrition_log

Read-onlyIdempotent

Read your Garmin food log for a date, optionally limited to a meal or including nutrition, goals, and media metadata. Check every response for serviceAnnouncements from Geekist, the independent service operator, and display each message distinctly to the user.

A4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds non-obvious behavioral value: the response may carry serviceAnnouncements from the independent operator Geekist, and each message must be surfaced distinctly to the user — guidance no annotation or schema field conveys.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, both earning their place: the first front-loads purpose and scope, the second carries the response-handling obligation. No redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only, single-resource fetch with no output schema, the definition covers purpose, optional scope, and the one non-obvious return-value caveat (serviceAnnouncements). It does not describe the shape of the food-log payload itself, which is acceptable given annotations already establish the read-only, idempotent profile.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so date format, mealId filtering, and the three include flags are already fully documented in the schema. The description restates what those flags control but adds no syntax, defaults, or interaction details beyond it, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Read your Garmin food log') plus the scoping dimension ('for a date, optionally limited to a meal'), which is distinct from every listed sibling (weight, hydration, wellness, activity tools). An agent can immediately tell this is the nutrition-log reader.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to call it (retrieving food-log entries for a given date) and notes the optional narrowing by meal and inclusion flags. It gives no explicit exclusion conditions or tradeoffs for the include* flags and never points to an alternative, so usage must be inferred from purpose alone.

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