get_nutrition_daily_food_log

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered, but the description adds nothing beyond the raw endpoint — no indication of what the response contains (meals, macros, servings) or how it is shaped. It is a bare route string with zero behavioral context.

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?

One short line with no filler, so it is efficient and front-loaded, but the brevity is under-specification rather than true conciseness — nothing an agent actually needs is expressed.

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 output schema and no annotations explaining the return payload, the description carries the burden of telling the agent what comes back, and it does not. For a retrieval tool whose whole value is the returned log data, this is a clear gap.

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 single `cdate` parameter is fully documented in the schema (calendar date, YYYY-MM-DD, UTC), so the baseline of 3 applies. The description contributes nothing the schema does not already say.

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 is essentially a restatement of the underlying HTTP route ("GETs `/nutrition-service/food/logs/{cdate}`") rather than a statement of what the tool does for an agent. It never says it returns the day's logged food entries, nor does it distinguish itself from siblings like get_nutrition_daily_meals or get_nutrition_food_log_range.

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?

There is no when-to-use guidance at all — no mention of when to prefer this single-day log over get_nutrition_food_log_range for multi-day queries, and no prerequisites. The path itself hints at per-date scope, but nothing explicit is offered.

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