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

With no annotations, the description carries the full burden and discloses several behavioral traits: it returns a downloadable URL (PDF, DOCX, or PPTX), supports Arabic and English, and costs 80 credits. This goes beyond the schema. It does not mention potential delays, failure modes, or side effects, but the provided details are valuable.

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 concise, consisting of four short sentences that front-load the main purpose and then efficiently add return format, language support, and credit cost. Every sentence contributes distinct, useful information with no fluff.

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 description covers the essential context: purpose, supported types (mostly), output format, language support, and cost. However, it omits the 'contract' type from the list, and there is no mention of processing time or error handling. Given the absence of an output schema and annotations, the description is fairly complete but has minor gaps.

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 provides 100% coverage for all parameter descriptions, so the baseline is 3. The description adds minimal parameter detail beyond the schema, and the list of document types (proposal, report, presentation, spreadsheet) omits 'contract' from the schema enum, which is a minor inconsistency but not a contradiction.

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 'Generate a professional business document' and lists specific types (proposal, report, presentation, spreadsheet), making it distinct from sibling tools like generate_video, generate_music, or create_design. The verb 'generate' plus the resource 'business document' is specific and 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 description implies usage for business document creation by listing document types, but it does not explicitly state when to use this tool versus alternatives such as create_design or write_copy. It also does not mention any exclusions or specific scenarios where this tool would be preferred over siblings.

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