Prepare: Saved Meal Item Operation (FatSecret)

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

The description discloses that it is a dry-run, a behavioral trait not in annotations. However, with readOnlyHint=false and openWorldHint=true, the term 'dry-run' is ambiguous regarding side effects. It does not explain whether a prepared operation is created or what other side effects may occur.

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 a single sentence with no fluff, front-loading the 'dry-run' concept. It is efficient, though the brevity sacrifices detail needed for full understanding.

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 tool with nested parameters and no output schema, the description is too minimal to guide correct use. It does not explain the prepare/commit workflow, required fields for the params object, or what the response will contain, making it incomplete for a complex operation.

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 description does not explain any of the three parameters (method, params, reason) beyond the schema. With 0% schema description coverage, it fails to compensate, leaving the agent without guidance on constructing valid inputs for this operation.

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 performs a dry-run for adding, editing, or removing a food inside a saved meal. It specifies the exact verb and resource, and the 'item' distinction differentiates it from sibling tools like fatsecret_prepare_saved_meal_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?

The 'dry-run' label implies this is for preflight validation before actual changes, but the description does not explicitly state when to use this over alternatives or how it fits with the commit_prepared_operation flow. No exclusions or alternative tools are named.

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