nexo_credential_create

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

The description minimally indicates a write operation ('store') but does not disclose important behavior such as whether existing credentials with the same service/key are overwritten, error handling, or response format. With no annotations, the description bears the full burden of transparency and falls short.

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 very concise (4 words) but lacks structure. It is front-loaded but too brief to be optimally useful; slightly longer description could improve clarity 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?

Given no annotations and no output schema, the description should provide more context about the credential creation process, such as security implications, idempotency, or integration with other credential tools. It is incomplete for a sensitive write operation.

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 coverage is 100%, so parameters are well-documented in the schema. The description adds no additional meaning beyond the schema descriptions, thus meeting the baseline of 3.

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 'Store a new credential', specifying a verb and resource. It distinguishes itself from sibling tools like delete, get, list, and update, though the differentiation is implicit via the action 'create'.

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, no prerequisites or conditions are mentioned, and there is no advice on avoiding misuse.

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