decimal_to_octal

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the conversion action but does not mention any behavioral traits such as error handling (e.g., for negative or non-integer inputs), performance characteristics, or output format details. The description is minimal and lacks context beyond the basic operation.

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 extremely concise and front-loaded: 'Convert decimal to octal (base-8) number system.' It wastes no words and directly states the core functionality. The domain and category tags are additional but not verbose. Every sentence earns its place.

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 minimal parameter coverage, the description is incomplete. It does not explain what the tool returns (e.g., a string or integer), how errors are handled, or any limitations. For a tool with no structured support, the description should provide more context to be fully helpful.

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 one parameter ('decimal') with 0% description coverage. The tool description does not add any parameter-specific information beyond what the schema name implies. Since there is only one parameter and its purpose is inferred from the tool name, the baseline score of 3 is appropriate, but no additional semantics are provided.

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: 'Convert decimal to octal (base-8) number system.' It specifies the verb ('convert'), resource ('decimal'), and target ('octal'), making the function unambiguous. However, it does not explicitly differentiate from sibling tools like 'decimal_to_binary' or 'decimal_to_hexadecimal', though the domain/category tags provide some context.

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. It mentions the domain ('arithmetic') and category ('number_systems'), but does not specify scenarios, prerequisites, or comparisons with sibling tools like 'base_conversion' or 'decimal_to_base'. Usage is implied by the name and description alone.

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