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

The annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered structurally. The description adds the useful scope detail that both manual and assistant-created entries can be deleted, but does not describe confirmation requirements, irreversibility, or the result of deleting a nonexistent id.

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?

A single front-loaded sentence with no filler; the resource is stated first and the id provenance follows immediately.

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 one-parameter destructive tool with full annotation coverage and no output schema, the description supplies what an agent needs to select it and locate the id. Only edge-case behavior (unknown id, effect on dependent records) is left unstated.

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?

With schema description coverage at 0%, the description carries the burden for the single id parameter. It adds real meaning by naming the source tools (get_entries, get_glucose), but says nothing about the id's format or what happens if the id is unknown or already deleted.

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 names a specific verb (borra) and resource (un registro), and scopes it to entries logged manually or by an assistant. It is clearly separable from the get_* siblings, which it references as id sources, though it does not explicitly contrast with other write tools such as log_* or finish_exercise.

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 states the prerequisite for use: the id must come from get_entries or get_glucose, which tells the agent how to obtain the required argument before calling. There is no explicit when-not-to-use guidance, but the scope restriction to manually or assistant-logged entries narrows the intended case.

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