Meal Plan Summary Tool

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

No annotations are provided, so the description carries the burden. It discloses that the tool returns a structured summary with recipe and section names, which is useful, but it does not describe any side effects, read-only nature, or behavior around missing data. Since it's a summary/read tool, the lack of explicit read-only disclosure is a minor gap.

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 a single, concise sentence that front-loads the main purpose. It earns its place without wasted words, though it could add a bit more context about the summary's scope.

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 tool has an output schema, so return values are covered. The description is adequate for a simple read/summary tool, but it lacks explicit guidance on how it differs from meal_plan_list_tool and whether any filters are required. Given the sibling set includes several meal-plan tools, a bit more context would improve completeness.

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%, so the schema already documents all three parameters. The description adds no additional meaning beyond what the schema provides, so the baseline 3 is appropriate.

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 specific verb ('Return') and resource ('structured meal-plan summary'), and mentions it includes recipe and section names. It is clear enough to distinguish from meal_plan_list_tool, which likely lists meal plans, but it doesn't explicitly differentiate itself from that sibling.

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 this tool is for retrieving a summary of a meal plan, and the optional date/section filters suggest when it might be used. However, it does not explicitly state when to use this tool versus meal_plan_list_tool or meal_plan_shopping_tool, nor does it mention any exclusions or alternatives.

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