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

Annotations already declare readOnlyHint=true, so safety is covered. Beyond that the description adds nothing: no ordering, no result volume, no indication of whether only recently saved meals appear, and no statement of what an empty result means for a client who has never saved a meal.

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?

It is short and wastes no words, but it is a bare noun phrase rather than a front-loaded statement of action and scope, leaving the reader to reconstruct the operation from the tool name.

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?

There is no output schema, so the description should at least sketch what a saved meal record contains or how results are ordered, and it does neither. For a single-parameter read tool this is simple enough to be callable, but not complete enough to be reliably interpreted.

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?

Only one parameter exists and schema coverage is 100%, with the schema even pointing to list_clients for obtaining clientId. The description adds no meaning beyond the schema, so the baseline of 3 applies.

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 fragment 'Meals a client saved for quick logging' identifies the resource (saved meals) and implies a read/listing scope, and the 'saved for quick logging' phrase distinguishes it from diet-log siblings like get_client_diet_logs. But it contains no verb and does not state that it returns a list scoped to one client, so purpose is inferable rather than explicit.

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 on when to use this versus related tools such as get_client_diet_logs, list_diet_plans, or search_recipes, and no mention of when it should not be used. The agent must infer usage purely from the name.

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