Accounts post api key

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

Annotations already declare this is a non-read-only, non-destructive, open-world mutation, so safety signaling is covered. The description adds that the output is a client_credentials login secret, which is genuinely useful, but it omits the critical behavioral fact that rotating invalidates the previous key and that the plaintext key is only returned once.

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?

A single compact sentence with the key fact front-loaded and no filler. It is arguably too terse for a credential-mutating operation, but nothing is wasted.

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 credential rotation endpoint with an opaque schema, no output schema, and zero annotation detail on side effects, the description says nothing about what gets invalidated, whether the new key is returned in the response, or what the three body parameters are for. An agent cannot call this safely on the strength of the description alone.

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 the three parameters (form, params, json_body) are untyped with 'default: null', so the schema provides essentially no guidance. The description does not mention any parameter at all — not even whether a name, expiration, or scope can be supplied.

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?

Names a specific verb pair (generate/rotate) and a precise resource (the personal API key), and the parenthetical 'client_credentials login secret' clarifies what the key is actually used for. The qualifier 'personal' distinguishes it from the organization-level key tools, though the sibling vaultwarden_accounts_rotate_api_key is left un-differentiated.

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 statement of when to call this versus vaultwarden_accounts_rotate_api_key or vaultwarden_organizations_rotate_api_key, both of which appear in the sibling list and overlap in intent. The word 'personal' only weakly implies account-scope, and there are no prerequisites or exclusions given.

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