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

With no annotations, the description must fully disclose behavior, but it only lists parameter names and types. It does not explain what operation is performed, whether it reads or writes, or any side effects or requirements.

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 very short but under-specifies the tool. Listing empty parameter definitions without context is not effective conciseness; it omits essential behavioral information.

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?

For a protobuf processing tool with no annotations, no output schema, and ambiguous parameters, the description is critically incomplete. It offers no help in understanding input requirements, output structure, or tool behavior.

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?

Although schema coverage is 100%, every parameter description is a tautology ('Data', 'Mode', 'Indent') that adds no meaning. The description also fails to explain allowed modes, data format, or how indentSize affects output, especially since 'decoded' appears as both an input schema property and output.

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 only says 'Protobuf' which is a restatement of the tool name and does not specify a verb or action. It fails to state whether the tool encodes, decodes, or processes protobuf data, making its purpose ambiguous and indistinguishable from sibling tools.

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?

No guidance is provided on when to use this tool versus the many sibling encoding, crypto, and format tools. There is no mention of use cases, prerequisites, or alternatives.

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