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

The annotations already indicate this is a non-destructive write operation (readOnlyHint=false, destructiveHint=false). The description adds the 'household's recipe collection' scope, which is useful context, but it does not disclose other behavioral traits such as name uniqueness requirements, potential errors, or permission needs. No contradiction with annotations.

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 short sentences. The first sentence directly states the action and optional parameters; the second gives workflow context by naming related tools. There is no redundancy or unnecessary detail.

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?

Given the tool's simplicity, full schema coverage, and the presence of an output schema, the description is sufficient. It clearly explains what the tool does and how it relates to meal planning and recipe browsing, but it could add a note about duplicate names or other edge-case behaviors for 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?

The input schema has 100% parameter description coverage, so the description doesn't need to explain the parameters. It merely lists the optional fields (ingredients, source URL, instructions, serving size), which adds no new meaning beyond what's already in the schema property descriptions.

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 identifies the verb ('Create'), the resource ('a new recipe'), and the scope ('household's recipe collection'). It also distinguishes the tool from siblings by mentioning create_meal_plan and list_recipes, which shows how it fits into the workflow.

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?

It provides context that after creating, you can link the recipe with create_meal_plan or browse with list_recipes, but it does not explicitly state when to use this tool versus alternatives like update_recipe or delete_recipe. There is no clear when-not-to-use guidance.

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