vault_encrypt_string

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 encrypts a string but doesn't reveal critical behaviors: whether it requires authentication, what encryption algorithm is used, if there are rate limits, what the output format is (e.g., encrypted string format), or potential side effects. This leaves significant gaps for an agent to understand how to use it effectively.

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 a single, efficient sentence with zero waste. It's front-loaded with the core purpose and appropriately sized for what it conveys, though it could benefit from additional context.

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 complexity (encryption tool with 4 parameters), no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It doesn't explain the return value, error conditions, dependencies, or parameter details, making it inadequate for safe and effective use by an AI agent.

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%, meaning none of the 4 parameters have descriptions in the schema. The tool description provides no information about parameters beyond implying 'string' is encrypted. It doesn't explain what 'vault_id', 'vault_password_file', or 'name' do, their formats, or defaults. This fails to compensate for the lack of schema documentation.

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 ('Encrypt') and the resource ('a string using Ansible Vault'), providing a specific verb+resource combination. However, it doesn't explicitly differentiate from its sibling 'vault_decrypt_string' beyond the obvious encryption vs. decryption distinction, which is why it doesn't reach a score of 5.

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 prerequisites like having Ansible Vault configured, when to choose encryption over other methods, or how it relates to sibling tools like 'vault_decrypt_string' beyond the implied inverse operation.

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