hash_md5

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

The description correctly declares a deterministic computation with no side effects, but omits that MD5 is cryptographically broken, which is behaviorally relevant for security-sensitive tasks.

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?

Achieved in one efficient sentence with no redundant 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 simple 1-param tool without output schema, the description is nearly complete, though it could specify the output format (typically hex-encoded string) for clarity.

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 100%, and the description's parameter info ('input string') adds no meaning beyond the schema's description. Baseline score applies.

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 verb 'Generate' and resource 'MD5 hash of the given input string', differentiating it from sibling hash tools by algorithm.

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 guidance on when to use MD5 versus other hash algorithms (e.g., SHA256). Usage is implied but lacks alternatives or security caveats.

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