hash_blake2s

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

No annotations given, so description must disclose behavior. Only states compute hash, no info on side effects, authentication, rate limits, or output format. For a hash tool, it's very minimal.

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 short sentence, front-loaded. Acceptable length but lacks important details, making it borderline too brief.

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 presence of many sibling tools and output schema, description fails to provide context: no explanation of output format, parameter defaults, or when to use this specific algorithm.

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 0%, and description adds no meaning for parameters 'data' or 'digest_size'. Agent must guess format or constraints from name and defaults.

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?

Description clearly states action (Compute) and resource (BLAKE2s hash) with bit length. However, it does not differentiate from sibling hash_blake2b, so agent may be unsure which to use.

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 on when to use this tool versus other hash functions (e.g., blake2b, sha256). No prerequisites or exclusions provided.

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