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

Annotations indicate readOnlyHint=false, which aligns with the description's 'Generate' action (implying a write/output operation). The description adds minimal behavioral context beyond annotations—it doesn't specify output format (e.g., hex string), performance, or error handling. With annotations covering basic safety, a 3 is appropriate as the description adds little extra value but doesn't contradict annotations.

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 extremely concise with just two words, front-loading the core action. There's no wasted language or redundancy. For a simple tool with one parameter, this brevity is appropriate and efficient, earning a top score for conciseness.

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?

Given the tool's simplicity (one parameter, no output schema), the description is incomplete. It lacks context on MD5's characteristics (e.g., fast, non-cryptographic), output format, or comparison to sibling hashing tools. Without annotations or output schema to fill gaps, the description should provide more guidance for effective use.

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%, with the 'text' parameter fully documented in the schema. The description doesn't add any parameter details beyond what the schema provides (e.g., no examples, constraints, or formatting tips). According to guidelines, baseline is 3 when schema coverage is high (>80%), which applies here.

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 'Generate MD5 hash' clearly states the action (generate) and resource (MD5 hash), but it's vague about what exactly is being hashed. It doesn't differentiate from sibling tools like hash_sha1, hash_sha256, or hash_sha512, which all perform similar hashing operations on text. The purpose is understandable but lacks specificity about scope.

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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention MD5's specific use cases (e.g., checksums, legacy systems) or warn against its cryptographic weaknesses compared to siblings like hash_sha256. There's no context on prerequisites or when-not-to-use scenarios, leaving the agent to infer usage from the tool name alone.

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