tool_classic_cipher

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only lists parameters and an output, but does not explain what transformation is applied, whether the operation is reversible, which algorithms are supported, or how the shift interacts with the algorithm. 'Outputs: result' is minimal and even conflicts with the input schema which also lists result as an input property.

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 short and has a clean structure with parameter and output sections. However, the parameter lines closely mirror the schema and add little value, so the conciseness is acceptable but the content is largely redundant.

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?

This is a crypto tool with no annotations and no output schema, so the description must compensate by explaining algorithm semantics, shift usage, and expected result. It does none of this, leaving the agent with an ambiguous skeleton. Sibling tool names also suggest a crowded crypto/encoding space, making the missing differentiation more damaging.

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 baseline is 3. The description simply repeats the schema's parameter names and descriptions, adding no accepted values, examples, or units. The 'Outputs: result' line is a small clarification, but it is confusing because the input schema also includes result as a property.

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 opens with '[crypto] Classic Cipher', which is essentially a restatement of the tool name and category. It does not state a specific action such as 'encrypt' or 'decrypt', nor does it clarify what 'Classic Cipher' actually does. The parameter list does not provide a clear verb+resource purpose.

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 given on when to use this tool versus alternative crypto tools such as tool_crypto, tool_hash, or tool_hmac. There are no exclusions, prerequisites, or examples of appropriate use cases.

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