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. While 'encrypt' implies a write/mutation operation, the description doesn't disclose important behavioral traits: whether this requires specific permissions, what happens to the original unencrypted string, whether the encryption is reversible only via the sibling tool, what format the output takes, or any rate limits. It mentions the technology (Ansible Vault) but not how it 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 at just 6 words, with zero wasted language. Every word earns its place: 'Encrypt' specifies the action, 'a string' specifies the target, and 'using Ansible Vault' specifies the technology. It's perfectly front-loaded with the core purpose.

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 a 4-parameter tool with no annotations, 0% schema description coverage, and no output schema, the description is inadequate. For an encryption tool that presumably produces important output, the description should explain what the tool returns, what the parameters mean, and any behavioral constraints. The current description leaves too many unanswered questions for effective tool selection and invocation.

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 and 4 parameters (only 1 required), the description provides no information about any parameters. It doesn't explain what 'name', 'vault_id', or 'vault_password_file' mean, nor does it clarify the semantics of the required 'string' parameter. The description fails to compensate for the complete 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 target resource ('a string using Ansible Vault'), providing a specific verb+resource combination. However, it doesn't distinguish this tool from its sibling 'vault_decrypt_string' beyond the obvious encryption vs. decryption difference, nor does it explain what makes this tool unique among other encryption-related tools that might exist.

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. There's no mention of prerequisites (like needing Ansible Vault configured), when encryption is appropriate, or what scenarios warrant using this specific tool over other encryption methods. The sibling tool 'vault_decrypt_string' is clearly related, but no explicit comparison is provided.

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