Prepare food-preference merge

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the mutation profile is known. The word 'stage' adds real value by implying a prepare/confirm two-step flow rather than a direct commit, but the description never states whether a confirm_action follow-up is required or what happens to the staged data.

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; the verb and target profile come first. Slightly under-specified rather than verbose, which is a content issue rather than a structure one.

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 mutation tool with no output schema, the description covers the inputs and implies a staging flow, but omits the lifecycle (what confirms the merge), permission needs, and merge semantics (replace vs. append). Adequate but with clear gaps.

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. It does name all four conceptual inputs (allergies, dietary preferences, disliked ingredients, cuisines), which maps well to the four parameters, but adds no format, syntax, or validation guidance beyond the field names.

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 merging') and resource (allergies/dietary preferences/disliked ingredients/cuisines) into a named profile. It is clear what the tool does, but it does not differentiate itself from closely related siblings like prepare_update_food_profile or prepare_update_profile.

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?

The description offers no when-to-use guidance or alternatives. It never explains the relationship to prepare_update_food_profile, nor whether this should be used for incremental 'newly stated' inputs versus a full profile update. Usage context is only faintly implied by 'newly stated'.

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