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

With no annotations provided, the description carries full burden for behavioral disclosure. While it mentions the output format options (hex or base64), it doesn't address important behavioral aspects like whether the operation is deterministic, what happens with empty input, performance characteristics, or security considerations for different algorithms. The description provides basic functional information but lacks depth about how the tool behaves.

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 - a single sentence that efficiently communicates the core functionality, available algorithms, and output options. Every word earns its place with no redundancy or unnecessary elaboration. It's front-loaded with the essential 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 utility tool with 100% schema coverage and no output schema, the description provides adequate basic information about what the tool does. However, given that there are no annotations and this is a cryptographic operation, more context about algorithm security, performance trade-offs, or common use cases would be beneficial. The description is minimally complete but could be more informative.

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 schema already fully documents all three parameters. The description mentions the algorithm options and output encodings, which aligns with what's in the schema but doesn't add meaningful semantic context beyond what's already specified in the structured fields. This meets the baseline expectation when schema coverage is complete.

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 action ('Hash a string') and specifies the available algorithms and output encodings. It distinguishes from sibling tools like 'gen_password' or 'gen_random' by focusing specifically on hashing. However, it doesn't explicitly differentiate from potential similar tools that might exist elsewhere.

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 provided about when to use this tool versus alternatives. The description doesn't mention prerequisites, limitations, or comparison with other hashing or encoding tools that might exist in the broader ecosystem. It simply states what the tool does without contextual guidance.

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