update_households_mealplans_rules_by_item

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

With no annotations, the description carries full burden for behavioral disclosure. It only implies mutation (Update) but omits details on idempotency, required permissions, side effects, or whether it performs partial vs full replacement. The description 'Update One' is too vague to inform the agent of behavior beyond the obvious.

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 extremely concise at two words, but this brevity comes at the cost of informativeness. It is a fragment that does not earn its place because it fails to convey any useful information beyond what the tool name already implies.

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 has 5 parameters, including enums and a required item_id, plus an output schema (as per context), the description is woefully incomplete. It does not explain the purpose, parameters, or expected behavior, leaving the agent with no actionable guidance for correct invocation.

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%, so the description must compensate, but it provides zero information about the 5 parameters. The schema includes enums for 'day' and 'entryType' and a required 'item_id', but the description adds no semantic meaning, leaving the agent to infer all meaning from parameter 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?

The description 'Update One' is a tautology that restates the verb 'Update' without specifying the resource or scope. It fails to distinguish this tool from the many other 'update' tools in the sibling list, such as update_households_mealplans_by_item or update_households_cookbooks_by_item.

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. The sibling list includes several update tools for meal plans, but the description gives no context for selecting this specific one over others like update_households_mealplans_by_item or update_households_shopping_items_by_item.

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