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

Annotations already declare readOnlyHint=false, destructiveHint=false and idempotentHint=true, so the safety profile is covered. The description adds the authorization requirement (admins only), which is useful context beyond annotations, but says nothing about what archiving actually does to the packet or to offers already referencing it, or whether it is reversible.

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 very short sentences, front-loaded with the action and the permission gate, with no filler. However it is a verbatim restatement of the title, so it is concise at the cost of carrying almost no information.

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 mutating, idempotent archive operation with no output schema and fully undocumented parameters, the description omits the idempotency_key contract, any statement of effect/reversibility, and any reference to related library-packet tools. Only the admin gate is communicated.

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?

Three parameters with 0% schema description coverage (packet_id, request_id, idempotency_key) and the description adds no parameter meaning at all. With coverage this low the description must compensate, and it does not mention any input.

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?

Tautological: description restates name/title.

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 'Admins only' clause is a real prerequisite that gates who may call it, but there is no when-to-use/when-not guidance and no named alternative (e.g., update vs archive vs delete). Usage is implied rather than explained.

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