Register client

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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is supplied structurally. The description adds nothing beyond that: it doesn't say what gets destroyed or overwritten (e.g. an existing DHCP host entry for that MAC), that re-registering is idempotent, or what happens on conflict — all of which matter for a destructive mutation.

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 the operation first and parameters second, with no filler. It is efficient, though the brevity is arguably under-specification rather than optimal concision.

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 destructive, idempotent mutation with no output schema, the description is too thin: it omits conflict/overwrite behavior, prerequisites, and any notion of what the caller gets back. The structured fields carry the safety profile, but the behavioral gaps remain.

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 100%, so the schema already documents mac, name, and ip with format examples. The description only restates these three fields at a high level and adds no extra meaning such as IP format, whether the IP must be inside the DHCP range, or uniqueness constraints.

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 (Register) and resource (device/client) and enumerates the inputs (MAC, name, optional static IP), which clearly separates it from sibling readers like get_clients or get_unregistered_clients. It does not, however, distinguish itself from the close sibling update_client or explain how it relates to set_dhcp_host.

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 when-to-use guidance and no comparison to alternatives such as update_client or set_dhcp_host, even though those siblings operate on the same client/DHCP concept space. The agent must infer the appropriate context from the name alone.

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