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

Annotations already declare destructiveHint=true, so the safety profile is partly covered. The description adds two genuinely useful behavioral facts beyond that: that historical diary entries sourced from the meal survive the deletion, and that the call previews unless confirm is true. It does not address permissions or whether the delete is recoverable, which keeps it below a 5.

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?

Three short, front-loaded sentences: the action first, then the most consequential side-effect detail, then the confirmation mechanic. Nothing is redundant or padded.

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 destructive, two-parameter tool with no output schema, the description covers the key concerns: what is removed, what is preserved, and the confirmation gate. The remaining gap is the provenance of the id argument, which an agent would have to infer from the sibling list tools.

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 50%: the confirm parameter is fully documented in the schema and the description reinforces its preview behavior. The id parameter has no schema description, and the description only implies it identifies a saved meal, not which identifier or how to obtain it, so the gap is only partially compensated.

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?

States a specific verb and resource ("Delete one of a client's saved meals"), which is unambiguous against siblings such as update_client_saved_meal or list_client_saved_meals. It does not explicitly name a sibling, but the delete semantics are clear enough that no schema has to be opened to tell them apart.

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 implication is that this tool is used when a saved meal should be removed, but there is no explicit guidance on prerequisites (e.g., obtaining the id from list_client_saved_meals) or on when to prefer update_client_saved_meal instead. The confirm gating is stated but not framed as a usage decision.

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