app_password_create

Generates an app password for a Nextcloud user via occ and returns it directly to the caller without storing it. Use this to obtain credentials that must be saved securely.

Instructions

Generate an app password for a user via occ. Returns the password to the caller — never stored or logged by this server. Store it securely (e.g. Vault) immediately after receiving it.

Behavior4/5

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

No annotations provided, so description carries full burden. It discloses that the password is returned only once and never stored/logged, which is critical. Missing details on authentication or rate limits, but the key behavioral trait is well communicated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the action, no redundant information. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers core functionality and security note. With an output schema (not shown), return values are assumed documented. Minor gaps: no mention that username must exist, but that is reasonable to infer.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, but description only indirectly mentions 'for a user' (mapping to username). The label parameter is not described at all, leaving the agent without guidance on its purpose or default behavior.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states it generates an app password for a user via occ, with a specific verb and resource. It distinguishes from siblings like user_create or app_manage by focusing on app password generation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides clear context on when to use (when needing an app password) and includes security instructions (store securely). However, it does not explicitly exclude alternatives or state prerequisites.

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