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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only mentions 'statistical analysis' and 'detects possible hidden payload' but omits any details on side effects, performance, network usage, or failure modes. This is insufficient for a tool with no 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?

The description is a single, compact line with no filler. It front-loads the key term 'LSB Steg Detect' and uses a dash to separate the method from the outcome. It is appropriately concise, though this brevity contributes to incompleteness in other dimensions.

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 likely to require an image input (e.g., file, URL, or base64) and return a detection result, but the description gives no hint of these. The output schema is present but unknown, and the description does not elaborate on the output or usage context. This is highly incomplete for a tool with no annotations.

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 describes a single parameter 'q' with no description (coverage 0%). The tool description does not mention 'q' at all, leaving the parameter's purpose and expected format completely undocumented. It fails to compensate for the low schema coverage.

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 a specific action: 'LSB Steg Detect' and 'Statistical LSB analysis', indicating it detects hidden payloads in LSB steganography. It is distinctive from sibling tools (none appear to target stego), so purpose is clear. However, it does not specify the expected input format (e.g., image file, URL, base64), which slightly reduces clarity.

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 no guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. It is a bare statement of functionality without context, leaving the agent to infer when it is appropriate.

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