Prepare recipe-serving log

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

Annotations already disclose the mutation profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false). The description adds meaningful context with 'Stage', signalling the action is queued rather than immediately committed. However it omits what happens after staging, whether it requires a saved meal request to exist, and how to commit or discard it.

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 filler. Every word contributes to the action, source, and target.

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?

With only one parameter and no output schema, the description is nearly sufficient, but for a staged mutation tool it should clarify the commit/discard mechanism and any precondition (an existing saved meal request). Those gaps leave an agent guessing about the follow-up step.

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?

The single parameter has no schema description (0% coverage), but the phrase 'from a saved meal request' semantically maps to meal_request_id as the source identifier. That is modest added value over the bare UUID pattern; no format or lookup guidance is given.

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 action (stage logging one serving) with a named source (a saved meal request) and destination (a ReceiptCal meal), which is far better than a tautology. It does not, however, explicitly differentiate itself from close siblings like prepare_log_recognized_food, prepare_log_barcode, or prepare_record_portion.

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, no prerequisites, and no mention of the alternatives for logging a serving. The 'prepare'/'stage' phrasing implies a two-step flow, but the description never names confirm_action/cancel_action or tells the agent when this path is preferable.

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