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

The annotations already declare read-only, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds context beyond that: the result set includes meal-time markings and per-serving nutrition, which tells the agent what shape of information it can reason over. Missing are notes on empty results or default behavior with no filters.

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?

Two sentences, both earning their place: the first establishes scope and returned content, the second supplies trigger phrases. Front-loaded and free of filler.

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 simple read-only list tool with two optional filters, an output schema, and rich annotations, this is close to sufficient. The only real gap is the default no-filter behavior, which is minor given the fully described schema.

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% and both enum parameters carry their own descriptions, so the schema does the heavy lifting. The description does not explain the slot or type filters or what happens when they are omitted, adding no meaning beyond the schema.

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 uses a specific verb and resource ("List the recipes and foods the user saved") and states what comes back (meal-time markings, per-serving nutrition). It implicitly separates itself from siblings like malai_search_foods or malai_get_food_log by scoping to saved items, though it never names an alternative directly.

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?

It gives concrete triggering phrasings ("what recipes do I have", "show my saved meals") and one downstream use case (suggesting something the user already likes). It stops short of explicit when-not conditions or naming a competing sibling tool to use instead.

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