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. While it mentions the bidirectional operation (encode/decode), it doesn't describe what the tool actually returns (e.g., code point format like U+XXXX, hexadecimal values, or something else), error handling for invalid input, or any limitations. For a tool with no annotation coverage, this leaves significant behavioral gaps.

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 - a single sentence that directly states the tool's core functionality. There's zero wasted language or redundancy. It's front-loaded with the essential information and doesn't include unnecessary elaboration.

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 tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what format the output takes (critical for a conversion tool), doesn't mention error conditions, and provides no examples of expected input/output. While the schema covers parameters well, the overall context for proper tool usage is incomplete.

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 description coverage is 100%, so the schema already fully documents both parameters (input and operation with enum values). The description adds no additional parameter semantics beyond what's in the schema - it doesn't explain input format expectations, encoding/decoding specifics, or examples. Baseline 3 is appropriate when the schema does all the parameter documentation work.

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: converting text to Unicode code points and vice versa. It specifies the bidirectional nature of the operation (text↔Unicode), which is more specific than just restating the name. However, it doesn't explicitly differentiate from sibling tools like convert_text_to_binary or convert_text_to_nato, which perform different text transformations.

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. With many sibling text conversion tools (e.g., convert_text_to_binary, convert_text_to_nato), there's no indication of when Unicode conversion is appropriate versus other encoding methods. No context about typical use cases or prerequisites is mentioned.

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