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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety and locality profile is fully covered. The description adds only that entries are trainer-saved and gives example template kinds; it says nothing about ordering, volume, or whether student-created templates are excluded.

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 short sentence with no filler, front-loaded on the resource. It is nearly too terse rather than padded, but nothing is wasted.

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 no parameters and no output schema, the description is the only place scope and return shape could be described, and it only partially is. An agent still cannot tell whether this returns the trainer's own templates only, what fields appear, or how it differs from list_diet_templates.

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 tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. No parameter-level claims are made that could mislead.

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 says these are meal templates saved by the trainer and gives parenthetical examples (breakfast, snacks), so the resource is identifiable. However it is largely a restatement of the name/title and does nothing to distinguish it from the closely named sibling list_diet_templates.

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 statement of when to use this versus list_diet_templates, list_favorite_foods, or search_foods, all of which an agent could plausibly reach for. The only contextual cue is 'the trainer saved', which hints at scope but is not framed as a selection rule.

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