list_dhcp_reservations

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered; the description contributes only the MAC-to-IP framing, which is minimal. It says nothing about whether results are empty when no reservations exist, whether they are paginated, or how entries relate to observed leases.

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?

It is short with no wasted words, but that brevity is under-specification rather than disciplined concision — a single fragment with no leading verb and no routing information. There is nothing to trim, but also almost nothing to work with.

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 not be explained, but for a tool sitting among list_dhcp_leases, add_dhcp_reservation, and delete_dhcp_reservation, the description gives no orientation within that family. The one thing an agent most needs — static reservations vs. active leases — is absent.

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?

The tool takes zero parameters, so the schema cannot be improved upon; the parenthetical at least tells the agent what a reservation record looks like conceptually (MAC to fixed IP). Baseline 4 applies for a parameterless tool.

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 is a noun phrase, 'DHCP reservations (MAC -> fixed IP)', with no verb; the action (listing) must be inferred from the tool name. It does identify the resource and hint at the data shape (MAC-to-IP bindings), but it does not distinguish this from the sibling list_dhcp_leases, which an agent could easily confuse it with.

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?

There is no guidance on when to use this tool, and crucially no mention of how it differs from list_dhcp_leases (dynamic leases) or from the write siblings add_dhcp_reservation/delete_dhcp_reservation. The agent must infer the read-only, static-binding scope entirely from the name.

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