get_meal_plan

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

With no annotations, the description carries full burden. It declares the operation is read-only ('Return'), but does not mention side effects, authentication needs, error behavior (e.g., missing plan), or rate limits. Basic transparency is achieved, but lacks depth for edge cases.

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, highly concise and front-loaded with the verb. Every word serves a purpose. However, it sacrifices completeness for brevity, which is acceptable given the tool's simplicity.

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?

Given two parameters, no output schema, and no annotations, the description is minimal. It lacks details about return value format, error scenarios, and how profile_id interacts with plan_id. Sibling tools are not addressed, limiting completeness for an agent.

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 description coverage is 0%. The description adds the special value 'latest' for plan_id and implies that profile_id is required when plan_id='latest', going beyond the schema. However, it does not explain other valid plan_id values or the exact role of profile_id, leaving ambiguity.

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 specifies the verb 'Return' and the resource 'stored meal plan', and mentions a special accepted value for plan_id ('latest'). It clearly indicates the tool's function, though it could more explicitly distinguish it from siblings like list_plans or generate_meal_plan.

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 is provided on when to use this tool versus alternatives (e.g., list_plans for listing all plans, generate_meal_plan for creation). The description implies retrieval of a single stored plan, but does not state when it is appropriate to use or not use this tool.

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