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

No annotations are provided, so the description must carry the full behavioral burden. It offers only the adjective 'Trusted' and says nothing about permissions, side effects, data flow, reversion, rate limits, or any other behavioral trait an agent would need.

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 phrase, not a sentence, and is under-specified rather than concise. It fails to front-load any meaningful information, so brevity here is a defect, not a virtue.

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?

With no annotations, no output schema, and no parameter schema, the description is the only source of information about this tool, and it provides none. An agent cannot confidently select or invoke this tool based on such a sparse definition.

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 tool has zero parameters, so there are no parameters to document. According to the evaluation rules, 0 params establishes a baseline of 4; the description neither adds nor detracts from that baseline.

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 'Trusted RAG augmentation' restates the tool name 'rag_augment' without adding a specific verb or clarifying what the augmentation does or what it operates on. It is essentially a tautology, and the vague 'Trusted' qualifier does not distinguish it from any sibling tool.

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?

There is no indication of when to use this tool versus alternatives, no prerequisites, and no exclusions. The description provides no usage context whatsoever.

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