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

No annotations are provided, so the description carries the full burden, and it does not state that this is a pure, non-destructive, stateless transformation. It also omits edge-case behavior (empty input, acronyms, non-ASCII characters, how existing separators are treated), which matters for a text transformer. The nature of the operation makes these gaps low-risk, keeping it at a minimum-viable 3 rather than lower.

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?

A single sentence that front-loads the verb and resource and then packs the complete option list with zero filler. Nothing could be removed without losing 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 two-parameter string utility with no nested objects and an enum-constrained target, this is nearly sufficient; the return value is obviously the converted string. The only real omission is the relationship to the sibling 'slug' tool and any note on input edge cases.

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 0%, so the description must compensate. It does effectively document the 'to' parameter by listing all seven target formats in readable form (camelCase, snake_case, kebab-case, PascalCase, UPPER, lower, Title), matching the enum. The 'text' parameter is left entirely to the schema, and no input-format expectations are set.

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 gives a specific verb ('Convert') and resource ('text') and enumerates the seven target formats, which resolves the ambiguity of the bare name 'case'. It does not explicitly distinguish itself from the sibling 'slug', which is the closest neighbor (slugify also rewrites text casing/punctuation), so it stops short of a 5.

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?

Usage is only implied: the enumerated output formats let an agent infer this is the tool for case normalization, but there is no statement of when to use it versus 'slug', no prerequisites, and no exclusions. For a simple utility this is acceptable but leaves the slug overlap unresolved.

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