vm_agent_set_password

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

No annotations are provided, so the description must fully disclose behavior. It only states the operation but omits preconditions (e.g., guest agent must be running), side effects, permission requirements, or the fact that the password might be encrypted. The crypted parameter is mentioned but its implications are not explained.

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 concise, with a short main sentence followed by an Args list. The structure is clear, but the Args list is somewhat redundant given the schema. It could be more streamlined without losing information.

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 no annotations and the tool's complexity (5 parameters, mutation, no output schema in view), the description is incomplete. It lacks behavioral context, prerequisites, and result information, which are critical for an AI agent to use it correctly.

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%, so the description must compensate. It provides a one-line explanation for each parameter (e.g., 'The username'), adding basic semantics beyond the schema titles. However, it lacks constraints, format details, or examples, so it only partially compensates.

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 ('Set a user password'), the target ('inside a VM'), and the method ('via the guest agent'). It is a specific verb-resource pair that distinguishes this tool from other VM agent tools like vm_agent_exec or vm_agent_file_read.

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 such as change_password or other vm_agent commands. There are no context cues or exclusion criteria to help an agent decide between similar operations.

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