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

With no annotations, the description does carry useful behavioral weight by disclosing the local-disk write side effect and that the source can be a URL or record ID. It omits overwrite behavior, permission/error handling, and whether large files are streamed, which matters for a filesystem-writing tool with zero annotation coverage.

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?

A single front-loaded sentence with zero padding; the destination behavior ('lưu trực tiếp vào ổ đĩa máy cục bộ') is stated up front rather than buried.

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?

For a simple 2-parameter tool with full schema coverage and no output schema, the core intent is covered. Still missing is what to expect on completion (saved path, overwrite/conflict handling) and error cases, which the absent annotations leave unaddressed.

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 both parameters are already documented with examples and accepted ID/URL forms. The description only echoes 'qua URL hoặc ID' without adding format or constraint detail beyond the schema, so the baseline 3 applies.

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?

Names a specific verb ('tải ... về lưu trực tiếp') and resource ('file âm thanh đã sinh từ BVoiz'), and the 'đã sinh' qualifier implicitly separates it from the synthesis siblings like bvoiz_synthesize_speech. It does not, however, explicitly contrast itself with any named sibling.

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?

Usage is only implied: download audio that already exists on BVoiz. There is no statement of when to prefer this over bvoiz_get_job_status or bvoiz_get_history, nor any prerequisite or exclusion conditions.

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