Prepare household profile update

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

Annotations already declare the safety profile (mutation, non-destructive, non-idempotent, closed-world), so the description needn't restate it. The word 'Stage' adds real value by signaling that the change is not applied immediately, but the description never explains what staging entails, whether omitted fields are preserved or cleared, or how the staged change is committed.

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 front-loaded sentence with no wasted words. It is efficient, though the terseness is part of why key behavioral details are missing.

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?

For a nine-parameter mutation tool with 0% schema coverage and no output schema, this is thin. It omits partial-update semantics, the confirm step, and per-field behavior, leaving the agent without enough to call it correctly.

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 carries the parameter burden. It groups the nine fields into rough categories (household, food-preference, allergy, retailer, timing, nutrition-target), which loosely maps to the schema properties, but it adds no per-field meaning, format, or update semantics (partial vs. replace).

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 ('Stage an update') and resource ('household...settings'), and enumerates the settings categories it covers. It does not distinguish itself from likely-overlapping siblings such as prepare_update_food_profile or prepare_merge_food_preferences, so an agent can't route between them from the description alone.

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 when-to-use or when-not-to-use guidance is given. The 'prepare_' prefix and the presence of confirm_action/cancel_action siblings imply a two-phase staging workflow, but the description never states that the update must be confirmed afterward or when this tool should be chosen over prepare_update_food_profile.

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