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 implies a mutation operation ('Change'), but doesn't specify permissions required, whether the change is reversible, rate limits, or error conditions. This is a significant gap for a tool that likely modifies critical credentials.

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 that directly states the tool's purpose without unnecessary words. It is appropriately sized and front-loaded, 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 of modifying credentials, lack of annotations, 0% schema coverage, no output schema, and two required parameters (including a nested object), the description is incomplete. It fails to address behavioral aspects, parameter details, or expected outcomes, leaving critical gaps for safe and effective tool invocation.

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 for undocumented parameters. It mentions 'Google service account' and 'cloud credentials record', which hints at the 'body' parameter's content, but doesn't explain the 'id' parameter or provide details on the 'body' structure beyond generic terms. This adds minimal value over the bare schema.

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 the target resource ('Google service account for a cloud credentials record'), making the purpose understandable. However, it doesn't differentiate from sibling tools like 'ChangeCloudCredsSecretKey' or 'ChangePasswordForCreds', which appear to modify similar credential-related entities, so it misses full 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, such as other 'Change' tools for credentials. It lacks context about prerequisites, exclusions, or specific scenarios, leaving the agent without usage direction beyond the basic purpose.

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