Remove Provider Key

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'Remove an API key' which implies a destructive action, but it does not disclose potential side effects (e.g., whether associated models are also deregistered, whether the action is reversible, required permissions, or confirmation mechanisms). The description does not contradict any annotations since none exist, but it offers no behavioral depth beyond the verb 'remove'.

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 a single clear sentence with no wasted words. It is appropriately short for a simple operation and front-loads the core intent. However, it is under-specified in terms of parameters and usage, but that is captured in other dimensions. The structure itself is efficient.

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, no output schema, and zero parameter descriptions, the description is incomplete. It does not mention any return value, error conditions, idempotency, or whether the key must be currently linked to a provider. An agent cannot fully anticipate the tool's behavior or side effects, making the description inadequate for the tool's complexity.

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%, meaning the description must explain the parameters. It does not. The description does not clarify what 'key_id' refers to, how to obtain it, or how the 'provider' enum relates to key removal. The agent must rely solely on parameter names and the enum values, which is insufficient for correct invocation.

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: 'Remove an API key from a cloud provider.' This is a specific verb-resource pairing that immediately distinguishes it from sibling tools like nanites_addProviderKey, nanites_listProviderKeys, and nanites_toggleProviderKey. No ambiguity about what the tool does.

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 its alternatives. It does not mention that this is the inverse of addProviderKey, nor does it explain any prerequisites (e.g., whether the key_id must exist or whether provider must be active). The agent must infer usage context from the name and siblings, which is insufficient.

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