households_mealplans_update_one

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

With no annotations provided, the description carries full behavioral burden. It says 'Replace (full update)' which hints at the mutation semantics, but it does not clarify required permissions, whether the item_id must already exist, whether omitted fields are cleared, or any side effects. This is insufficient for a write operation.

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 short, but the large keyword list adds noise without informational value. The front-loaded operation summary and API path are useful, but the trailing keywords are excessive for the size of the content.

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 a write operation with zero annotations, no output schema, and 0% parameter description coverage, the description is incomplete. It should explain the full-replace behavior, parameter requirements, and likely authentication context, none of which are present.

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 description coverage is 0% and the description provides zero explanation of parameters. The body fields (date, id, userId, groupId, recipeId, entryType, etc.) and the item_id path parameter are completely undocumented semantically, leaving the agent to infer meaning from property names alone.

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 (Replace/Update) and resource (meal plan) and includes the HTTP method and path, making it clear this is a full-replace update. It does not differentiate from siblings like households_mealplans_get_one, households_mealplans_create_one, or the more granular households_mealplans_update_many in the description text itself, relying only on the tool name.

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?

No guidance is provided on when to use this tool versus alternatives such as households_mealplans_update_many or households_mealplans_create_one. The description merely lists keyword synonyms (edit, modify, save, write) without any conditional or exclusion statements.

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