post_w_company_credentials

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 states that this is a POST/create operation, but it does not disclose what happens on success, what the response contains, whether authentication is required, what fields are mandatory, or whether the operation is reversible. For a mutation tool, this is a significant transparency 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 three short sentences with no filler. The core operation is front-loaded, and the parameter-placement guidance is compact. It could be slightly more structured, but every sentence contributes useful information.

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 input schema is entirely unhelpful and the description does not compensate with required payload details, credential semantics, or path parameter specifics. An agent would struggle to construct a valid request beyond knowing where to put values. The tool is described only as a bare HTTP wrapper, which is insufficient for a create operation with no annotation support.

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 has 0% description coverage and generic object types for body, query, headers, and path_params. The description adds meaningful guidance by mapping route IDs to path_params, filters/pagination to query, headers to headers, and payload to body. However, it does not explain which route IDs, filters, or payload fields are expected, leaving the agent to guess at actual values.

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 a specific verb and resource: 'Create credential' and the exact endpoint `POST /w/company/credentials`. This clearly distinguishes it from sibling tools like get_r_company_credentials, patch_w_company_credentials, and delete_d_company_credentials_id. It is slightly generic but unambiguous.

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 verb 'Create' implies when to use this tool, and the CRUD siblings imply alternatives, but no explicit when/when-not guidance or named alternative is provided. The usage context is clear enough for a simple create operation, but the description does not explain prerequisites or cases where a different tool should be chosen.

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