webdev_hex_viewer

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

No annotations are provided, so the description must fully disclose behavior. It mentions viewing hex dumps with ASCII representation and analysis, but does not cover potential side effects, authentication needs, rate limits, or what 'detailed analysis' entails. The lack of behavioral depth is a significant gap for a tool with no structured annotations.

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 three sentences long and contains the core information, though the first sentence includes redundant 'Menu ID: hex_viewer. Hex Viewer.' It is structured well with a clear progression, but could be slightly more concise.

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?

Given the lack of annotations, output schema, and parameters, the description covers basic functionality but omits limitations (e.g., file size, supported formats) and details about the analysis. The pointer to describe_tool partially compensates, but the description itself is not fully complete.

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 input schema has 0 defined parameters (additionalProperties: true), so the description does not need to add parameter meaning. Baseline for zero parameters is 4, and the description does not detract from this.

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: 'View and analyze binary data in hexadecimal format' and specifies actions like uploading files or pasting data to generate a hex dump with ASCII representation and analysis. It distinguishes itself from sibling tools (e.g., conversion tools) by being a viewer/analyzer, not a converter.

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 gives user actions ('Upload files or paste binary data') but does not provide explicit guidance on when to use this tool versus alternatives, nor does it state when not to use it. The pointer to describe_tool suggests more guidance exists elsewhere, but the description itself lacks usage context.

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