credential_management

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It vaguely states 'handles' but does not clarify whether operations are read-only, destructive, require specific permissions, have rate limits, or what the typical outputs are. For a tool with 8 parameters and no annotations, this lack of behavioral context is a significant gap.

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 concise with two short sentences and no wasted words. It is front-loaded with the main purpose. However, it could be more structured by explicitly listing key actions or use cases to improve clarity without adding unnecessary length.

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 (8 parameters, no annotations, but with an output schema), the description is incomplete. It does not explain the multi-action nature implied by the 'action' parameter, the relationships between parameters, or typical use cases. While the output schema may cover return values, the description fails to provide enough context for effective tool selection and 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?

The schema description coverage is 100%, with each parameter clearly documented in the schema (e.g., 'action' with enumerated values, 'credential_id' as ID). The description adds no additional parameter semantics beyond what the schema provides. According to the rules, with high schema coverage (>80%), the baseline is 3 even without param info in the description.

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 the tool handles 'credentials, credential types, and access tokens' but is vague about what 'handles' means. It restates the name 'credential_management' without specifying concrete actions like create, update, delete, or list. While it mentions three resource types, it lacks a clear verb that distinguishes its purpose from siblings like 'user_access_management' or 'gateway_auth_management'.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention any prerequisites, context for selection, or exclusions. With siblings like 'user_access_management' and 'gateway_auth_management' that might overlap, the absence of usage guidelines leaves the agent guessing about appropriate scenarios.

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