Get Capture Interfaces

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

readOnlyHint=true already declares this is a safe read, and the description adds nothing further — no note on whether it requires the capture feature enabled, whether interfaces can be empty, or what state the router must be in. For a zero-arg read tool this is tolerable but thin.

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 no wasted words, though its brevity borders on under-specification rather than aggressive editing.

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?

The tool is simple (0 params, read-only, output schema present, so return values need not be described), but the description omits the workflow context — when in the capture setup process to call it — which would be the one piece of value it could add.

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?

There are zero input parameters, so the baseline is 4 and the description has no parameter semantics to add. Nothing is misrepresented or missing.

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 (get) and resource (network interfaces), qualified by the scoping phrase 'available for packet capture', which cleanly separates it from get_ping_interfaces and get_tcpdump_config. It does not explicitly name a sibling, but the qualifier is enough to disambiguate.

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 gives no when-to-use context, no prerequisites, and no alternatives; it is purely a restatement of what is returned. An agent must infer that this feeds a packet-capture workflow rather than, say, a ping or traceroute workflow.

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