nodesAddNodeLoopbacks

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states 'Add' which implies a write/mutation operation, but doesn't disclose any behavioral traits like whether this is idempotent, what permissions are required, if it's destructive to existing loopbacks, or what happens on success/failure. The description is minimal and lacks critical context for a mutation tool.

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?

The description is concise (two sentences) but inefficiently structured. The first sentence states the purpose clearly. The second sentence provides basic usage syntax but doesn't add meaningful value beyond what the schema already implies. The description could be more front-loaded with context rather than syntax reminders.

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 mutation tool with no annotations and no output schema, the description is inadequate. It doesn't explain what 'Add' entails operationally, what the expected outcome is, error conditions, or relationship to other tools. The 100% schema coverage helps with parameters, but the overall context for using this tool is incomplete.

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 fully documents all 3 parameters (fabricId, nodeId, loopbacks). The description adds no parameter semantics beyond what's in the schema - it only provides a generic example of argument passing format. Baseline 3 is appropriate when the schema does all the heavy lifting.

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 clearly states the action ('Add one or more loopbacks') and identifies the resource (loopbacks). It distinguishes from siblings like 'nodesUpdateNodeLoopback' (update) and 'nodesDeleteNodeLoopback' (delete), but doesn't explicitly differentiate from 'nodesGetNodeLoopbacks' (read). The purpose is specific but could be slightly more precise about the context (fabric/node).

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 provides no guidance on when to use this tool versus alternatives. It mentions how to pass arguments but not when this tool is appropriate compared to siblings like 'nodesUpdateNodeLoopback' or 'nodesDeleteNodeLoopback'. There's no mention of prerequisites, dependencies, or typical use cases.

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