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

With no annotations, the description carries the full burden, and it does add one genuinely useful behavioral fact: 'Self-inverse' tells the agent the same call both encodes and decodes, removing the need for a separate inverse operation. It says nothing about how non-alphabetic characters, case, or non-ASCII input are handled, so the disclosure is partial.

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?

Two short sentences, front-loaded with the operation and mapping, and the trailing property note is dense rather than filler. Nothing is wasted and nothing essential is buried.

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 single-parameter, no-output-schema transform, the description is nearly sufficient: purpose, mapping, and the self-inverse property are all covered. The only real omission is edge-case behavior for digits, punctuation, and case, which an agent would otherwise have to discover by trial.

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?

There is one parameter at 100% schema description coverage ('Text to encode/decode.'), so the schema already does the work; baseline is 3. The description's 'to text' confirms the input type but adds no format, length, or charset detail beyond the schema.

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?

States a specific verb (apply) and resource (Atbash cipher), and spells out the mapping (A=Z, B=Y, ...) so the transformation is unambiguous without opening anything else. It does not differentiate itself from cipher/encoding siblings such as rot13_convert, vigenere_process, or morse_convert, which keeps it 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 implied rather than stated: the agent can infer this is the tool for Atbash transformations, and 'Self-inverse' hints it serves both encoding and decoding. There is no explicit when-to-use or when-to-prefer-an-alternative guidance relative to the many other cipher tools in the sibling list.

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