Create Random Meal Plan Entry

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

Annotations already declare this is a non-read-only, non-destructive, closed-world write. The description adds real value by disclosing that the recipe choice is made by the server and constrained by household meal plan rules, which the agent could not know otherwise. It omits failure behavior, such as what happens when no recipe satisfies the rules or whether the entry can be re-randomized.

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?

A single well-formed sentence with the key mechanism (random selection) front-loaded and the side effect (added to meal plan) immediately after. No filler, though the parenthetical slightly interrupts the flow.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. For a mutation with a nondeterministic outcome, however, the description should say what the agent gets back or what happens when the rule set yields no candidate, leaving a meaningful 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 coverage is 100% and the day and meal parameters are fully described in the schema, including the enum and default. The description adds no additional meaning about parameter behavior, so the baseline of 3 applies.

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?

States a specific verb ('pick a random recipe') and resource ('add it to the meal plan'), which clearly distinguishes it from the deterministic sibling create_meal_plan_entry. It never names that sibling explicitly, so the differentiation is implied rather than stated.

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 phrase 'let Mealie pick' implies the use case (when the agent/user has no recipe preference), but there is no explicit when-to-use or when-not-to-use guidance and no pointer to create_meal_plan_entry for deterministic selection. Usage must be inferred by comparing sibling names.

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