create_meal_plan

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

No annotations are present, so the description must reveal behavioral traits, but it only states that it creates an entry and optionally links a recipe. It does not disclose validation behavior for recipeId, duplicate handling, side effects, permissions, or the shape of a successful response.

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 two concise sentences with no filler. The action verb is front-loaded, and the optional linking behavior is mentioned without repetition.

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 5 parameters, no annotations, and no output schema, the description covers only the high-level action. It omits important operational context such as whether a linked recipe must exist, what happens if the date already has an entry, and what the caller receives downstream.

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?

The input schema provides 100% parameter descriptions, including enum values for entryType and defaults for title/text. The description adds only high-level context about date and optional recipe linking, not exceeding what the schema already conveys.

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 uses a specific verb ('Create'), resource ('meal plan entry'), and scope ('specific date'), clearly distinguishing it from sibling meal-plan tools like list_meal_plans and delete_meal_plan. It also clarifies the optional recipe linking, which sets it apart from recipe-only creation tools.

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 usage for adding a new meal plan entry but does not explicitly state when to use it over alternatives or provide exclusions. No cross-reference to related tools like list_meal_plans or create_recipe is included.

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