interface_status

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

The [READ] tag and readOnlyHint=true are consistent, so no contradiction. However, with annotations covering only the read safety profile, the description adds little else: no statement about ordering beyond 'down interfaces first', no mention of scope (all interfaces?), rate limits, or auth requirements.

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?

Front-loads the [READ] marker and purpose, then lists the single argument in a compact Args block. No wasted words, though the formatting resembles a docstring rather than an agent-facing instruction.

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 single optional-param read tool with no output schema, the description covers the essentials of what it returns and one argument. It does not explain the default target behavior beyond a phrase, nor any pagination/filtering, leaving some gaps for multi-target environments.

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% and the sole parameter 'target' has only a title and default, so the description must compensate. It does briefly — 'Firewall target name from config; omit for the default' — but does not specify format or where 'config' draws the name from.

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+resource ('Interfaces with link status + address'), which is more informative than a bare tautology. It doesn't explicitly differentiate from siblings like gateway_status or health_status, but the resource is distinct enough to be selectable.

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?

No guidance on when to use this vs alternatives such as gateway_status, health_status, or firmware_status. The phrase 'target: Firewall target name from config' hints at multi-target usage but does not establish selection criteria or exclusions.

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