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

With no annotations, the description carries the behavioral burden. It discloses that the operation is offline and covers four algorithms, but it does not state side effects, output structure, or behavior for empty input; however, the output schema covers return values.

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?

Single compact sentence, front-loaded with the verb and resource, with no filler. The algorithm list and offline note are the only details included.

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 pure hash tool, the description is close to adequate, and the presence of an output schema reduces the need to document return values. However, the missing parameter explanation and lack of alternative guidance leave clear gaps.

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 needed to explain the meaning of 'q' as the text to hash. It refers to 'text' generally but never names or describes the parameter, leaving the agent to infer the mapping.

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 clear action ('Hash') and resource ('Text'), and enumerates the algorithms (md5/sha1/sha256/sha512), so an agent knows exactly what operation this performs. The parenthetical 'offline' hints at a distinction from lookup-style hash tools, though it does not explicitly name siblings.

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 explicit when-to-use or when-not-to-use guidance is provided. The description implies use when local text hashing is needed, but it does not contrast with nearby siblings like checksum, hashid, or sha256lookup, so an agent must infer the appropriate context.

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