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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false and openWorldHint=false, so the description needs only to add context such as what is destroyed, whether it is recoverable, or what the response contains. It adds nothing beyond the verb, leaving the agent with no information it did not already have from the structured fields.

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?

Six words is appropriately front-loaded and free of waste, but the brevity is under-specification rather than economy — nothing here earns the space it occupies because nothing here is informative.

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?

A destructive, irreversible mutation with no output schema and no description of consequences, authorization, or error behaviour leaves the agent unable to reason about whether it should call this at all. The annotations cover the safety flag but not recoverability or effects, so the description should carry that and does not.

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?

One required parameter at 0% schema description coverage — the description does not say what an entryId identifies, where the agent obtains one (joiva_get_day, joiva_list_meals?), or what the format expectation is. The schema carries only the type and UUID pattern, so the description must compensate and does not.

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?

"Delete a Joiva log entry" gives a verb and a resource, but it is essentially the tool name restated with a space instead of an underscore. No sibling differentiation is offered against joiva_update_log_entry, joiva_log_food, or the parallel stackwell_delete_intake / vora_delete_* family.

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 indication of when to delete versus when to update (joiva_update_log_entry) or how to correct a mistaken log. There are no preconditions, no alternatives, and no exclusion guidance despite a large sibling set that includes an obvious near neighbour.

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