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

Annotations already declare destructiveHint=true and readOnlyHint=false, but the description adds genuinely new behavioral context: the operation is a soft archive that never hard-deletes data, and it requires explicit user confirmation. That clarifies what 'destructive' actually means here and what precondition the agent must satisfy, which annotations cannot convey.

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 short sentences, zero filler, with the core action stated first and the safety constraint immediately after. Nothing is redundant with the title or schema.

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?

An output schema exists, so return values need no explanation, and annotations cover the safety profile. The description supplies the confirmation precondition and the soft-delete guarantee, which is close to complete for this operation; only the identifier parameters remain unexplained.

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% across three required parameters (vehicleId, trackerId, confirmed). The description only indirectly gestures at 'confirmed' via the confirmation requirement and says nothing about what vehicleId/trackerId identify or their expected format, so it fails to compensate for the documentation gap.

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 (archive) and a specific resource (connected user maintenance item), which distinguishes it from the archive_vehicle/archive_session/archive_setup siblings by resource type. It does not explicitly contrast itself with those siblings or with update_maintenance/complete_maintenance, so it stops short of a 5.

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 description implies usage (archive a maintenance item when it is no longer active) and adds one real prerequisite: explicit user confirmation. However, it never says when to prefer this over update_maintenance, complete_maintenance, or the list/delete siblings, and gives no exclusions, so guidance is implied rather than stated.

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