Change a meal plan entry

update_mealplan_entry
DestructiveIdempotent

Change a meal plan entry by moving it to another day or meal slot, swapping its recipe, or editing its title or note. Text edits require a confirmation token.

Instructions

Moves an entry to another day or slot, or replaces the recipe behind it. Replacing the written title or note of an entry requires confirmation: call once to receive a token, then again with that token. Moving the entry or swapping the recipe does not.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
dateNo
textNo

recipeNoRecipe slug (e.g. "quark-bowl") or recipe UUID — both are returned by search_recipes
entry_idYesPlan entry id from list_mealplans — an integer, not a UUID
entry_typeNoWhich meal of the day this entry belongs to
confirm_tokenNoConfirmation token from a previous call of this tool with the same arguments. Omit on the first call.

TDQS

A3.9/5.0
Behavior4/5

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

Beyond the annotations (destructive, idempotent), the description discloses the confirmation flow: title/note changes require a token from a prior call, while moves and recipe swaps do not. This is useful behavioral context not present in annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise (three sentences) and front-loads the main operations. It efficiently conveys the confirmation nuance. Slightly complex phrasing around title/note replacement could be clearer, but it remains compact and focused.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the 7 parameters and output schema, the description provides adequate context: it identifies the main edit operations, clarifies the confirmation requirement, and distinguishes which changes need a token. It does not explain the response format, but output schema presumably covers that. Lacks explicit mention of required entry_id, though schema specifies it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema descriptions cover recipe, entry_id, entry_type, and confirm_token, but date, text, and title lack descriptions. The description partially compensates by mentioning 'another day or slot' (date/entry_type) and 'written title or note' (text/title), but does not explicitly map these terms to parameters, leaving some ambiguity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: moving an entry to another day/slot, replacing the recipe, or updating the title/note. It distinguishes itself from create/delete mealplan tools by focusing on modifying existing entries, and the title 'Change a meal plan entry' reinforces this.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explains what actions the tool performs and the confirmation requirement, but it does not explicitly compare to alternatives like create_mealplan_entry or delete_mealplan_entry. The use case is implied (update existing entries), but explicit 'use this instead of X' guidance is absent.

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