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

The readOnlyHint=false annotation already signals a mutation, and the description repeats this with 'WRITE operation', but it adds a specific role requirement (pac_cordinator or lunch_cordinator) that is not in the annotations. It does not describe failure modes, idempotency, or effects on existing data, but the annotation profile covers the basic write/destructive expectations.

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 very short and front-loaded with the ADMIN tag, with no wasted sentences. It loses one point because 'WRITE operation' largely repeats readOnlyHint=false and 'ADMIN' repeats the annotation title, but the overall structure is efficient.

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 7-parameter create operation with zero parameter descriptions, the description is too sparse to support fully correct invocation: parameter semantics, side effects, and sibling-tool routing are all missing. The presence of an output schema reduces the return-format burden, but the input side remains substantially underdocumented.

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 carry the burden of explaining the 7 parameters. It only implies restaurant association and menu-item creation, leaving restaurant_id, name, calories, cost_cents, description, ingredients, and price_cents without semantic or unit context.

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 states a specific verb ('Creates'), a concrete object ('menu item'), and a parent scope ('for a restaurant'), which cleanly distinguishes this from siblings like create_restaurant, update_menu_item, and delete_menu_item. The ADMIN prefix adds an access boundary without obscuring the operation.

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?

There is no explicit when-to-use guidance or mention of alternatives such as update_menu_item for modifying existing items or set_daily_menu for daily menu assignments. The role requirement implies an admin-only caller but does not help an agent decide between this and related tools.

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