account_credentials_create

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

Description only restates the obvious (create operation) without adding behavioral traits beyond what annotations already indicate (readOnlyHint=false). It does not disclose details like idempotency, authentication requirements, or error conditions.

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?

Single sentence is efficient and gets the point across with no wasted words. However, it could be slightly more descriptive without losing conciseness.

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?

Despite having an output schema, the description is too vague for a create operation with a generic object parameter. It does not explain required fields in the body or the broader context of account-level credentials, leaving significant ambiguity.

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 sole parameter 'body' has a description 'Credential body' in the schema (100% coverage). The tool's description adds no extra semantic meaning beyond the example 'e.g. for storage', which is insufficient to fully specify the body structure.

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?

Description clearly states the verb 'Create' and resource 'account-level credentials' with an example 'for storage'. It effectively distinguishes from siblings like delete and list, but could be more precise about the scope of account-level credentials.

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 on when to use this tool versus alternatives (e.g., other credential creation tools). No exclusions or prerequisites mentioned.

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