hires_list_company_id_mail_accounts

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

With no annotations, the description carries the burden of disclosing behavior. It reveals an access constraint (company must be own or client) and clarifies the scope (all users in the company). However, it does not mention pagination, error handling, or what happens if the company is not accessible, which would be valuable for a list operation.

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, clear sentence that is front-loaded with the primary action. No wasted words, and it includes a critical constraint without verbosity.

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?

The tool is a simple list operation with three parameters and no output schema. The description provides essential context (company accessibility and scope) but lacks details about response format, pagination behavior, or error cases. Given the sibling ambiguity, a bit more context would improve completeness, but it meets the minimum viable threshold.

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 100%, so the baseline is 3. The description adds context about the 'id' parameter being a company that must be accessible, but this is marginal. It does not explain the 'page' or 'size' parameters beyond the schema, which is acceptable since the schema already covers them.

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 tool lists all mail accounts for all users in a specific company, which is a specific verb and resource. However, it does not explicitly differentiate from the similarly named sibling tool 'hires_list_company_mail_accounts', so it misses some sibling differentiation.

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 a prerequisite (company must be accessible) but gives no explicit guidance on when to use this tool versus alternatives like 'hires_list_user_mail_accounts' or 'hires_list_company_mail_accounts'. No exclusions or alternative scenarios are mentioned.

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