hash_sha512

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

The description indicates it computes a hash and returns a hex-encoded string, but lacks details on string encoding (e.g., UTF-8) or deterministic behavior. Since no annotations exist, the description carries the full burden but is adequate for a simple hash tool.

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 very concise, with a clear three-line format including Args and Returns. Every sentence serves a purpose with no redundancy.

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 hash function, the description covers the essential information: input (string to hash) and output (hex-encoded hash). It is complete given the low complexity and existence of an output schema.

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?

With 0% schema description coverage, the description adds the meaning that 'data' is a string to hash. This is minimal but sufficient given the single parameter.

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 'Compute SHA-512 hash' and mentions the input and output format. However, it does not differentiate from sibling tools like hash_sha256 or hash_sha1, though the name itself provides the distinction.

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 on when to use SHA-512 versus other hash functions, nor are there any context or alternatives mentioned.

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