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

The description adds idempotency details and specific error returns (already_exists, not_found) beyond the annotations (idempotentHint=true, destructiveHint=true). No contradictions; the description enriches behavioral understanding.

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?

Two concise sentences: first states the action, second covers idempotency and return behaviors. No wasted words, front-loaded with key information.

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?

While basic behavior is covered, the description omits important context for parameters like dryRun, comment, routerId, and confirmationToken. Given the destructive action and lack of output schema, these missing details reduce completeness.

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 parameters. The description reinforces the composite key (list+interface) but does not add new semantic details for other parameters like dryRun, comment, or confirmationToken.

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 tool adds or removes an interface from an interface list, with specific idempotency and return behaviors. This distinguishes it from sibling tools like manage_interface_list (which likely manages the list itself) and other management tools.

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 explicit when-to-use or when-to-avoid guidance is provided. While the action is clear, no distinction is made between using this tool versus other membership management tools. Usage is implied but not detailed.

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