brc_multi_company_nom_ac_report

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

No annotations are provided. The description indicates it uses GET calls, implying a read-only operation, but does not disclose behavioral traits such as whether the report is cached, pagination behavior, rate limits, or authentication requirements. 'Creates' could be misinterpreted as a state change, but the actual operation is idempotent retrieval.

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, focused sentence. It immediately states the purpose and the mechanism, with no wasted words. It is front-loaded and easy to parse.

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 tool's moderate complexity (one parameter, simple array input) and the presence of sibling tools, the description is adequate but not complete. It does not explain the output format or how results from multiple companies are grouped, which is essential for an agent to use the tool effectively.

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 the single parameter 'companyNames' having a clear description and example. The tool description does not add additional semantic value beyond what the schema already provides, so a baseline score of 3 is warranted.

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 it creates a grouped nominal accounts report for multiple companies, specifying the verb 'creates' and the resource 'nominal accounts report'. It distinguishes from the sibling 'brc_list_nominal_accounts' (which lists accounts) but does not explicitly differentiate from 'brc_grouped_nominal_accounts_report', which may be a similar report for a single company.

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 its siblings. It mentions the underlying GET call but does not state prerequisites, when not to use, or mention alternatives like 'brc_grouped_nominal_accounts_report' for single-company reports.

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