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 states 'Update' which implies a mutation operation, but fails to describe critical aspects like required permissions, whether the change is reversible, potential side effects, or rate limits. This leaves significant gaps in understanding the tool's behavior.

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 extremely concise with just three words, front-loading the essential information without any wasted text. Every word earns its place by directly communicating the tool's core function.

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 happens after the update, whether there's confirmation feedback, error conditions, or how this interacts with other tools. Given the complexity of updating API credentials, more context is needed for safe and effective use.

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?

The input schema has 100% description coverage, with the single parameter 'openai_token' clearly documented as 'OpenAI API Key'. The description adds no additional semantic context beyond what the schema provides, such as format requirements or validation rules, meeting the baseline for high schema coverage.

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 ('Update') and the resource ('OpenAI API Key'), making the tool's purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'update_deepseek_token' or 'update_gemini_token' beyond the specific token type, which is a minor gap in sibling distinction.

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, prerequisites, or context. It lacks explicit instructions on usage scenarios, such as when updating tokens is necessary or how it relates to other configuration tools like 'update_smtp' or 'update_twilio_number'.

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