Create Saved Meal Template

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

Annotations already indicate the tool modifies data (readOnlyHint=false) and is not destructive. The description adds that it returns the created saved meal with its ID. No additional behavioral context is provided beyond annotations.

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 extremely concise: two sentences plus a brief parameter list and return statement. Every sentence adds value, with no redundancy.

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?

The description covers purpose, next-step sibling usage, parameters, and return value. It lacks explanation of idempotency or duplicate behavior, but for a simple creation tool this is sufficient.

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 coverage is 100%, so the description adds marginal value. It slightly improves the meal_type description by noting it is used 'when copied to diary,' which is helpful. Baseline 3 is appropriate.

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 clearly states the tool creates a reusable meal template, provides an example, and distinguishes from siblings by directing to the next step (using fatsecret_add_food_to_saved_meal).

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 gives clear context for when to use (creating a template) and mentions the next step, but does not explicitly exclude use cases or compare to other sibling tools like copy or direct food entry. Still, the guidance is sufficient.

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