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

With no annotations, the description carries the full burden and does so excellently: it discloses that the operation is immediate and irreversible, that the old key stops working immediately, and that failure to update the environment variable causes loss of access. These are exactly the behavioral traits an agent must know.

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 front-loaded with the core action and consequence. Some repetition exists (the IMPORTANT and Note sections both emphasize updating the environment variable), which is slightly redundant, but the structure is logical and nothing is wasted on irrelevant detail.

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 zero-parameter, irreversible credential-rotation operation with no annotations, the description provides everything needed: what it does, that it's irreversible, what it returns, and the mandatory follow-up action. Even though an output schema exists, the description translates the return into actionable guidance.

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 parameters, so the baseline is 4. The description appropriately spends no space on parameter semantics and instead describes the returned api_key, which is the critical output for this operation.

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 states a specific verb+resource ('Generate a new API key and invalidate your current one') and is unmistakably distinct from all sibling tools, which are read/query operations. The purpose is fully unambiguous.

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?

It says when to use it ('to rotate your API credentials for security purposes'), which is clear context. However, it doesn't discuss alternatives or when-not-to-use, so it doesn't reach the explicit when/when-not level of a 5.

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