Tick off or change shopping list items

update_shopping_list_items
DestructiveIdempotent

Check off or modify items on a Mealie shopping list: tick items, change quantities, or replace item text with confirmation. Only specified fields change, preserving the rest.

Instructions

Changes items on a shopping list — most often ticking them off. Only the given fields are changed; the rest of each item is preserved. Ticking off and changing quantities is immediate; replacing the text of the items with note requires confirmation, because that text is overwritten on every item named and Mealie keeps no copy.

Input Schema

list_idYesShopping list UUID, from list_shopping_lists
item_idsYesItem UUIDs from get_shopping_list
quantityNoSet the quantity of every listed item
confirm_tokenNoConfirmation token from a previous call of this tool with the same arguments. Omit on the first call.

TDQS

A4.7/5.0
Behavior5/5

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

The description discloses important behavioral details beyond annotations: that text replacement is destructive, overwrites all named items, and requires confirmation. It also notes that ticking off and quantity changes are immediate, which aligns with the destructiveHint and idempotentHint annotations without contradiction.

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

Conciseness5/5

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

The description is concise, two sentences, and front-loaded with the core action. It efficiently conveys the most important nuances without unnecessary detail, making it easy to parse.

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

Completeness5/5

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

Given the tool's complexity (confirmation token, destructive text replacement), the description covers the essential context. It explains the confirmation requirement and the immediate vs. confirmation-based actions. No output schema is needed to be described per rules, and the description is sufficient for an agent to use the tool correctly.

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

Parameters4/5

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

The description adds meaning to parameters by explaining that only listed fields are changed and that note replacement requires a confirm_token. While schema descriptions already cover each parameter, the description provides context on the confirmation flow and the overwrite behavior, enriching parameter understanding.

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 function: changing items on a shopping list, with examples like ticking off, adjusting quantity, and replacing text. It is distinct from sibling tools like add or delete, as it focuses on modifying existing items.

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

Usage Guidelines4/5

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

The description implies when to use this tool (update existing items) versus adding or deleting, but it does not explicitly mention alternatives. It does clarify that only provided fields are changed, which guides usage, though it could be more explicit about not using it for creation.

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