Text-Toolkit

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool generates a hash but doesn't mention whether this is a read-only operation, if it has side effects, performance characteristics, or what the output format looks like. For a cryptographic tool with zero annotation coverage, this leaves significant behavioral gaps.

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 at just three words, with zero wasted language. It's front-loaded with the essential information and doesn't contain any unnecessary elaboration or repetition.

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 cryptographic hashing tool with no annotations and no output schema, the description is insufficient. It doesn't explain what format the hash output takes (hexadecimal, base64, etc.), whether the operation is deterministic, or any security considerations. The description should provide more complete context for proper tool usage.

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?

The description mentions 'SHA-512 hash' which implies text input, but doesn't explicitly describe the 'text' parameter beyond what the schema provides. With 0% schema description coverage and only one parameter, the description adds minimal semantic value. The baseline is appropriate given the simple parameter structure.

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 SHA-512 hash' clearly states the verb ('Generate') and resource ('SHA-512 hash'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like generate_md5, generate_sha1, or generate_sha256, which perform similar hashing operations with different algorithms.

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 like generate_md5 or generate_sha256, nor does it mention any prerequisites, constraints, or typical use cases for SHA-512 hashing. It simply states what the tool does without contextual usage information.

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