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

With no annotations, the description must disclose behavior, but it only says 'transform strings between... etc.' without explaining edge cases, reversibility, or what 'detect' mode does. It is too vague for a transformation tool.

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 entire description is a single, front-loaded sentence with no filler. It conveys the core function immediately and is appropriately concise for a simple tool.

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 simple tool with complete schema descriptions and no output schema, the description is minimally sufficient. However, it omits details about mode behaviors and potential formatting outputs, making it only moderately complete for an end user.

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% for both parameters, so the baseline is 3. The description adds no additional parameter meaning beyond the schema, and the 'mode' enum values are not explained beyond their names, but the schema does document basic purpose.

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 transforms strings between common naming conventions (camelCase, snake_case, etc.) with a specific verb and resource. However, it does not explicitly distinguish from sibling tools like code-formatter or regex-tester, though the purpose is reasonably unique.

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 alternatives, nor does it explain the differences between the 'mode' options (case-convert, slug, detect). The description gives no context for selecting this tool over other string utilities.

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