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

With no annotations, the description should disclose behavioral traits. It mentions handling surrogate pairs and code points, but does not describe output format, error handling, limitations, or whether operations are case-sensitive. This leaves important 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 three sentences and fairly concise. The first sentence contains a Menu ID which is not useful for the agent, but overall it is reasonably structured and not verbose.

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 zero annotations, no output schema, and 0% parameter coverage, the description should be thorough. It provides only high-level purpose and a pointer to more info. Missing parameter details, return value specification, and error conditions make it 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 coverage is 0%, so the description must clarify parameter meanings. It implies that 'operation' refers to escape/unescape and 'format' refers to the listed formats, but does not explicitly define valid values for these parameters or explain the 'text' parameter. This is insufficient for correct invocation.

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 it is a 'Unicode Escaper/Unescaper' that handles escape and unescape operations for Unicode characters in multiple formats (JSON, Python, Java, CSS, HTML, XML, URL). It explicitly mentions handling surrogate pairs and all code points, which distinguishes it from sibling encoding 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?

The description lists supported formats but does not provide explicit guidance on when to use this tool versus alternatives. It mentions using `describe_tool` for full guidance, but lacks direct exclusions or when-not-to-use scenarios.

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