jpegadv_compatibility

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

With no annotations provided, the description carries full burden for transparency. It discloses that the tool analyzes properties and lists them, suggesting a read-only operation. However, it does not explicitly state that no modifications are made, nor does it mention any prerequisites or side effects.

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 with two sentences. The first sentence states the purpose directly, and the second provides essential detail on what is analyzed. No extraneous information or redundancy.

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?

While the description explains the analysis scope, it does not mention the output format or how results are presented (e.g., list of tools, confidence scores). Given the complexity of compatibility analysis and lack of output schema, this omission limits the agent's ability to interpret results accurately.

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 coverage is 100% with a clear description of the single parameter 'file_path'. The tool description adds minimal value beyond the schema, merely confirming the file type (JPEG) without adding constraints, format specifics, or examples.

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's purpose: a JPEG stego tool compatibility check that analyzes image properties to determine which steganography tools could have been used. It provides specific details on analyzed properties (color space, quality factor, etc.), effectively distinguishing it from sibling tools that focus on specific detection or structure analysis.

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 initial assessment of potential stego tools, but it does not provide explicit guidance on when to use this tool versus specific sibling detectors (e.g., jpegadv_f5_detect). No exclusion criteria or alternatives are mentioned, leaving the agent to infer context.

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