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

No annotations are provided, so the description carries full burden. It implies a mutation operation ('Change') but doesn't disclose behavioral traits like required permissions, whether changes are reversible, rate limits, or what happens on success/failure. For a tool that modifies credentials, this is a significant gap in safety and operational context.

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, efficient sentence with zero wasted words. It's front-loaded with the core action and resource, making it easy to parse quickly.

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?

Given the complexity (a mutation tool with 2 parameters, nested objects, and no output schema), the description is inadequate. It lacks details on parameters, behavioral implications, error handling, and output expectations, leaving significant gaps for an AI agent to use it correctly.

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%, so the description must compensate. It mentions 'secret key for a cloud credentials record' but doesn't explain the 'id' parameter (likely the credential identifier) or the 'body' object (presumably containing the new secret key details). Without this, parameters remain largely undocumented.

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 ('Change') and target resource ('secret key for a cloud credentials record'), making the purpose specific and understandable. However, it doesn't differentiate from sibling tools like 'ChangePasswordForCreds' or 'ChangePrivateKeyForCreds', which appear to handle similar credential modifications.

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 (e.g., 'ChangePasswordForCreds' or 'UpdateCloudCreds'), nor does it mention prerequisites, exclusions, or context for invocation. It's a bare statement of function without usage context.

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